The surprising finding? Dolphins are much more sensitive to these sounds than previously predicted, reacting at significantly lower levels than current regulatory impact assessments anticipated.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Groundbreaking Research Unveils New Insights</h2><p class=\"reg-normal\">The study, published on October 23 in Royal Society Open Science, involved an international team that conducted experiments with 34 dolphin groups, comprising thousands of individuals. The experiments tested the animals’ responses to both simulated and operational military sonar under carefully controlled conditions, as well as in situations where no sonar was played as a control measure. The results uncovered some unexpected behaviors in response to the noise.</p><p class=\"reg-normal\">\"We see clear evidence of acoustic responses—fine-scale changes in movement, including directed, sustained, strong avoidance, and changes in group configurations,\" explained Brandon Southall, the study\'s lead author and a senior scientist at Southall Environmental Associates (SEA). \"These behaviors occur on variable time scales, but they collectively show that dolphins respond to sound levels much lower than what regulatory guidelines predict. It’s clear that these animals are far more sensitive to noise exposure than we had thought.\"</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Innovative Techniques Bring New Precision to Dolphin Research</h2><p class=\"reg-normal\">The research utilized a novel approach by integrating aerial drone imagery, underwater listening recorders, and shore-based visual observers to monitor dolphin behavior. This combination of methods provided a comprehensive picture of how these social animals react to acoustic disturbances, says co-author Ari Friedlaender, an ocean sciences professor at UC Santa Cruz.</p><p class=\"reg-normal\">One key technological advancement used was \"drone photogrammetry,\" a non-invasive technique for measuring animal behavior from drone-captured photographs. John Durban, a senior scientist at SEA and co-author of the study, noted that SEA has pioneered this approach over the past decade for monitoring whale and dolphin health. \"In this study, we were able to develop this technique further to geolocate dolphins with centimeter-level precision, allowing us to quantify behavioral changes in an objective way,\" Durban stated.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Why Understanding Dolphin Sensitivity to Sonar Matters</h2><p class=\"reg-normal\">Social dolphins, which often gather in groups of hundreds or even thousands, are found off California’s coast and in many other regions. These areas frequently see the use of powerful military sonar systems, known to disturb and even harm various marine species. Before this study, there had been no direct data on how such sonar might impact dolphins, despite predictions that millions of these animals could be affected annually.</p><p class=\"reg-normal\">Concerns about sonar\'s impact on marine life have increased due to recent incidents where mass strandings of cetaceans, including dolphins, coincided with naval sonar operations. These strandings typically occurred when mid-frequency tactical sonars (1-10 kHz) were used, with most systems operating in the 3-4 kHz range.</p><p class=\"reg-normal\">\"Understanding how these animals respond to these acoustic signals is vital for mitigating the effects of this kind of disturbance,\" said Caroline Casey, a UC Santa Cruz researcher and study co-author. \"These disturbances can significantly impact social animals that rely on sound for communication, feeding, and other critical aspects of their lives.\"</p>','2024-10-24 22:55:09.472799','uploads/news/images_3_cm6AB6p.jpeg',1,'University of California - Santa Cruz','A new study reveals that dolphins are more sensitive to military sonar than previously believed, reacting at lower sound levels than expected.

Thankfully, deep-sea sediments contain microbial communities that act as natural filters, breaking down these compounds before they can escape into the oceans or the atmosphere. This process, known as anaerobic oxidation of alkanes, is crucial for maintaining the ocean\'s health, yet it remains one of the least understood areas of microbial biochemistry.</p><p class=\"reg-normal\">A recent breakthrough by scientists at the Max Planck Institute for Marine Microbiology in Bremen, Germany, offers new insights into this fascinating process. The researchers have published a study in Nature Communications detailing how certain microbes degrade ethane, the second most abundant alkane found in these deep-sea seeps. By identifying and characterizing the enzymes responsible for ethane degradation, the team has not only filled in some of the gaps in our knowledge but also overturned a long-standing assumption in the field.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\" style=\"font-family: &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif; color: rgb(51, 51, 51);\">A Missing Piece in the Microbial Puzzle</h2><p class=\"reg-normal\">While the anaerobic oxidation of ethane has been known for some time, the underlying mechanisms remained shrouded in mystery. \"When we tried to map out the chemical reactions involved, we found large gaps in our understanding of how these microbes extract energy,\" explains Olivier Lemaire, the study\'s first author. It became apparent that the traditional models of microbial metabolism did not fully apply.</p><p class=\"reg-normal\">The accepted view was that these microbes, like many others, used a protein called ferredoxin to handle the electrons produced during the conversion of ethane into carbon dioxide (CO2). However, when the researchers examined the microbes\' genomes, they discovered something unexpected: the necessary enzymatic machinery for ferredoxin-based energy extraction was missing. This revelation suggested the microbes had found another way to fuel their cellular processes.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\" style=\"font-family: &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif; color: rgb(51, 51, 51);\">An Unusual Collaboration That Unveiled a Hidden Pathway</h2><p class=\"reg-normal\">Solving this metabolic mystery required the combined efforts of multiple research teams at the institute. Gunter Wegener and his group tackled the challenging task of sampling and cultivating the ethane-degrading microbial communities from the seafloor. \"Working with these microorganisms is incredibly demanding because of their unique growth conditions, but our perseverance paid off,\" says Wegener.</p><p class=\"reg-normal\">Meanwhile, Tristan Wagner\'s team focused on isolating and studying the enzymes involved in ethane oxidation. This painstaking process allowed them to identify a crucial difference in the enzyme structure: an additional protein subunit, connected to the enzyme by an iron-sulfur \"wire.\" This novel configuration pointed to a different electron acceptor—F420, a molecule similar to vitamin B2, widely recognized for its role in human health.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\" style=\"font-family: &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif; color: rgb(51, 51, 51);\">A Metabolic Rewiring That Challenges Conventional Wisdom</h2><p class=\"reg-normal\">The discovery that these enzymes could use F420 as an electron acceptor was groundbreaking. \"Such an arrangement has never been seen before in CO2-generating enzymes,\" remarks Wagner. By confirming the use of F420 in the microbial oxidation process, the team effectively broke a dogma in the field of anaerobic metabolism. This finding expands our understanding of how enzymes can function and highlights the metabolic flexibility of these deep-sea microbes.</p><p class=\"reg-normal\">The researchers propose that the coupling of CO2 production with F420-based electron transfer could enhance the efficiency of the entire process. The electrons are then transferred across the cell membrane to another microbe, which uses them to reduce sulfate—a common process in communities of alkane-oxidizing microbes. This discovery reveals a previously unknown layer of complexity in the interaction between different microbial species at the deep-sea seeps.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\" style=\"font-family: &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif; color: rgb(51, 51, 51);\">Unraveling the Impact of Ethane-Degrading Microbes</h2><p class=\"reg-normal\">By shining a light on the unique metabolic pathways of ethane-degrading microbes, the researchers have provided a crucial piece to the puzzle of the ocean\'s carbon cycle. These microbes play a vital role in containing naturally occurring alkane emissions, thus acting as a biological barrier that prevents massive outflows of pollutants into our atmosphere and oceans.</p><p class=\"reg-normal\">Moreover, the study serves as a reminder that the conventional wisdom derived from studying a few well-known microorganisms doesn\'t always apply universally. \"Our findings illustrate just how little we still know about the metabolism of these ancient microbes, which have existed on Earth for billions of years,\" concludes Wagner. \"Their ability to adapt to diverse environments is far greater than we often assume, and understanding these adaptations requires hands-on experimental approaches.\"</p><p class=\"reg-normal\">This research not only deepens our understanding of microbial ecology but also has broader implications for environmental science and climate change mitigation. By revealing how deep-sea microbes help regulate the planet\'s carbon cycle, the study underscores the importance of protecting these often-overlooked ecosystems that play a significant role in maintaining Earth\'s balance.</p>','2024-10-24 23:08:20.800446','uploads/news/images_4.jpeg',1,'Max Planck Institute for Marine Microbiology','Researchers at the Max Planck Institute for Marine Microbiology have uncovered a surprising mechanism for the anaerobic oxidation of ethane, challenging established ideas in biochemistry.

A new study from Northwestern Medicine reveals a novel approach to alleviating narcolepsy-related nightmares, combining cognitive behavioral therapy for nightmares (CBT-N) with lucid dreaming techniques. The research, recently published in the Journal of Sleep Research, shows that this combined therapy can significantly reduce nightmare severity and frequency, potentially transforming the way sleep is managed for those with this chronic condition.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Why Nightmares in Narcolepsy Deserve Attention</h2><p class=\"reg-normal\">Nightmares affect 30-40% of individuals with narcolepsy, a neurological disorder that disrupts the brain\'s control over sleep and wake cycles. These nightmares aren\'t just unsettling—they can cause sufferers to fear sleep itself, leading to increased fatigue, anxiety, and even depression. Yet despite their impact, narcolepsy-related nightmares have long been overlooked in both research and clinical treatment.</p><p class=\"reg-normal\">\"Narcolepsy-related dreams have been an overlooked symptom within narcolepsy,\" said Jennifer Mundt, assistant professor of neurology and psychiatry at Northwestern University Feinberg School of Medicine and the study\'s lead author. \"People in the study had nightmares for decades but never received treatment, often because they were never asked about nightmares or didn\'t know treatments existed.\"</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">A First-of-Its-Kind Approach to Treatment</h2><p class=\"reg-normal\">This study is the first to apply CBT to address nightmares specifically related to narcolepsy. CBT-N, a variation of cognitive behavioral therapy that targets nightmares, has previously shown effectiveness in treating trauma-related nightmares. In this trial, six participants received weekly telehealth sessions over six weeks, during which they learned about sleep habits, bedtime relaxation techniques, and the process of rescripting their nightmares into preferred dream scenarios.</p><p class=\"reg-normal\">\"Imagine you\'re rewriting a movie script,\" explained Mundt. Participants created new, positive versions of their nightmares and mentally rehearsed these scripts every night before bed, in an effort to change the content of their dreams.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Introducing Lucid Dreaming into the Mix</h2><p class=\"reg-normal\">Halfway through the study, three participants underwent an additional procedure called targeted lucidity reactivation (TLR). TLR, which was tested in the lab of Ken Paller, professor of psychology at Northwestern, aims to induce lucid dreaming—a state in which the dreamer is aware they are dreaming and can sometimes control the dream. Using electroencephalogram (EEG) monitoring, scientists identified when participants entered the REM sleep stage, where lucid dreams are most likely to occur.</p><p class=\"reg-normal\">During REM sleep, the researchers played sound cues, such as a piano chord or specific words like \"calm\" or \"family,\" which participants had associated with their rescripted dream during prior rehearsals. The idea was to trigger lucidity and guide the dreamer into experiencing their preferred dream scenario.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Promising Results and Participant Reactions</h2><p class=\"reg-normal\">The results showed a significant improvement in all participants. After completing the treatment, every participant reported that their nightmares were less frequent and less intense. In four cases, nightmare severity dropped below the threshold for a nightmare disorder diagnosis.</p><p class=\"reg-normal\">While the small sample size prevented a formal comparison between the CBT-N only group and the CBT-N plus TLR group, the findings offer a promising proof-of-concept. Two participants in the TLR group entered REM sleep during the nap session, and one signaled lucidity by moving their eyes back and forth, as planned. Even those who did not formally signal lucid dreaming still reported dreams that resembled their rescripted scenarios.</p><p class=\"reg-normal\">\"When they were telling us about their dreams, they remembered similarities to the rescripted scenario,\" Mundt noted. \"This is really unique—patients undergoing traditional CBT-N don\'t typically experience their rescripted dream as vividly.\"</p><p class=\"reg-normal\">Participants described feeling less anxious and embarrassed about their nightmares following the treatment. For some, the experience was transformative. \"It\'s empowering for them,\" said Mundt. \"They\'re so surprised this works. It increases self-efficacy for managing their symptoms, and they describe how glad they are that this helped. It\'s really a game-changer, mentally.\"</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">The Potential of Combining CBT with Lucid Dreaming</h2><p class=\"reg-normal\">Narcolepsy-related nightmares have gone untreated for too long. This innovative approach, which merges established psychological therapy with cutting-edge sleep science, may open new doors for managing sleep-related disorders. By combining CBT-N with techniques like TLR, there is potential not only to reduce nightmares but also to optimize the restorative effects of sleep.</p><p class=\"reg-normal\">As Paller suggests, “This research highlights a new orientation to sleep, opening the door to novel methods for fine-tuning sleep to enhance its benefits and perhaps make people more likely to wake up on the right side of the bed.”</p><p class=\"reg-normal\">The study\'s next steps may involve larger trials to confirm these early findings and to explore the potential long-term benefits of using CBT and lucid dreaming techniques for people with narcolepsy.</p>','2024-10-24 23:40:37.705836','uploads/news/images_5.jpeg',1,'Northwestern University','A Northwestern Medicine study has found that combining cognitive behavioral therapy (CBT) and lucid dreaming techniques can reduce the severity and frequency of narcolepsy-related nightmares.

We often receive these snippets of information faster than we can process spoken words. But can we truly comprehend these quick texts as easily as we perceive the visuals that constantly fill our screens?</p><p class=\"reg-normal\">According to recent research by linguistics and psychology experts at New York University, the answer appears to be \"yes.\" The studies, detailed in Science Advances and the Journal of Neuroscience, reveal that our brains can detect the basic structure of a brief sentence in about 150 milliseconds—roughly the time it takes to blink.</p><p class=\"reg-normal\">\"Our experiments show that the brain\'s language comprehension system can perceive language almost as quickly as it perceives visual scenes,\" explains Liina Pylkkänen, a professor at NYU and the study\'s lead researcher. \"This suggests that our brains can process language much faster than previously thought—faster than the time it takes to hear a single syllable.\"</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">The Digital Shift in Reading</h2><p class=\"reg-normal\">The way we consume information has transformed dramatically with the rise of email, social media, and smartphones. Reading has shifted from being a leisurely, in-depth activity to something far more fragmented and fast-paced. Now, our brains are tasked with processing short, rapid-fire messages that pop up constantly across various digital platforms.</p><p class=\"reg-normal\">\"This shift makes it clear that not only do our brains have the capacity to instinctively process these rapid messages, but we can also make snap decisions based on them—like deciding to delete an email or how to react to a brief social media update,\" notes Pylkkänen. \"But how deeply do we understand these quick snippets, and how do our brains handle them?\"</p><p class=\"reg-normal\">The new research suggests that our brains can, at least partially, grasp the meaning of fast messages from just a glance, indicating something fundamental about the language system\'s processing capabilities.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Challenging Conventional Models of Language Processing</h2><p class=\"reg-normal\">Traditional language processing theories describe how we understand spoken language word by word, building meaning incrementally. However, this approach does not fully explain how our brains can process entire sentences in an instant—especially when the sentences are seen rather than heard.</p><p class=\"reg-normal\">To explore this, the researchers conducted a series of experiments using magnetoencephalography (MEG) to measure brain activity. Participants were shown either grammatical three-word sentences, such as \"nurses clean wounds,\" or unstructured word lists like \"hearts lungs livers.\" The results were striking: within 130 milliseconds, the brain’s left temporal cortex, a region associated with language comprehension, began to distinguish between structured sentences and mere word lists.</p><p class=\"reg-normal\">\"This rapid speed suggests that our brains comprehend a sentence flashed on a screen similarly to how they perceive a visual scene—quickly grasping its essence rather than processing it step by step,\" explains Pylkkänen. \"In the time it takes to hear just one syllable, the brain can detect the structure of a sentence.\"</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">The Brain’s Automatic Error Correction</h2><p class=\"reg-normal\">Interestingly, even when a sentence contained grammatical errors, such as a mismatch in verb agreement (\"nurses cleans wounds\") or lacked plausible meaning, this quick detection of structure still occurred. Jacqueline Fallon, the study’s first author, explains, \"This indicates that the brain\'s initial response reflects the detection of basic phrase structure, rather than deeper grammatical correctness or meaning.\"</p><p class=\"reg-normal\">Supporting research published in the Journal of Neuroscience, led by NYU graduate student Nigel Flower, found that even small mistakes in phrase structure—such as swapping adjacent words (\"all are cats nice\")—triggered a drop in the brain\'s rapid response. Yet, starting around 400 milliseconds, the brain appeared to \"correct\" the mistake internally, processing the sentence as if it were grammatically accurate.</p><p class=\"reg-normal\">\"This suggests that the brain not only quickly recognizes phrase structure but also automatically corrects minor errors,\" Flower adds. \"This explains why we often overlook small mistakes—our brains have already smoothed them over.\"</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Implications for Understanding Language and the Brain</h2><p class=\"reg-normal\">By presenting entire sentences all at once, instead of word by word, the researchers uncovered the brain’s ability to swiftly identify basic linguistic structures, even if the sentences made no sense or contained grammatical errors. The studies provide new insights into the brain\'s inherent language processing capabilities, independent of the sequential nature of spoken language.</p><p class=\"reg-normal\">\"These findings suggest that the human brain is equipped with an impressive capacity for rapid language comprehension, enabling us to cope with the barrage of information in our digital lives,\" says Pylkkänen. \"It challenges us to rethink the nature of language processing and the brain’s remarkable speed at interpreting both written words and visual scenes.\"</p><p class=\"reg-normal\">Supported by grants from the National Science Foundation and the NYU Abu Dhabi Institute, this research not only broadens our understanding of language comprehension but also highlights the adaptability of the brain in the age of digital communication.</p>','2024-10-25 00:07:48.223192','uploads/news/images_6.jpeg',1,'New York University','Recent studies by NYU researchers show that our brains can quickly grasp the structure of short sentences flashed on a screen, detecting basic linguistic patterns in just 130-150 milliseconds—about the time it takes to blink.

As the epidemic persists, the need for effective interventions has never been more urgent. Naloxone, a lifesaving drug commonly available as a nasal spray or injection, can quickly reverse an overdose by restoring normal breathing. However, its success often depends on having someone nearby who knows how to use it—an unfortunate barrier for many.</p><p class=\"reg-normal\">In a promising development, a collaborative team from Washington University School of Medicine in St. Louis and Northwestern University in Chicago has created a device that could change this scenario. The new implantable device has been shown in animal studies to detect opioid overdoses, deliver naloxone autonomously, and notify emergency responders—all without the need for a bystander. The study detailing these findings was published on Oct. 23 in Science Advances.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Challenges with Current Naloxone Use</h2><p class=\"reg-normal\">“Naloxone has saved many lives,” says Robert W. Gereau, PhD, a leading researcher in the study and the Dr. Seymour and Rose T. Brown Professor of Anesthesiology at Washington University. “But during an overdose, people are often alone, unaware of what\'s happening to them. Even if someone else is present, they need access to naloxone—also known as Narcan—and must know how to administer it within minutes. We saw an opportunity to address these challenges by developing a device that can automatically deliver naloxone to individuals at risk.”</p><p class=\"reg-normal\">Prescription painkillers like oxycodone have played a role in helping individuals cope with severe pain, yet their addictive nature has fueled misuse and abuse. The surge of synthetic opioids, such as fentanyl—highly potent and often illicitly manufactured—has further escalated overdose deaths, accounting for around 70% of such fatalities in 2023.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Introducing the Naloximeter: A Game-Changer in Overdose Intervention</h2><p class=\"reg-normal\">To tackle these issues, the research team collaborated with experts in engineering and materials science under the leadership of John A. Rogers, PhD, at Northwestern University. They designed an innovative device called the Naloximeter, which is implanted under the skin and continuously monitors oxygen levels. Opioid overdose causes breathing to slow down and eventually stop. The Naloximeter senses when oxygen in the surrounding tissues drops below a critical level, triggering an emergency response.</p><p class=\"reg-normal\">Here’s how it works: If the oxygen levels dip dangerously low, the device sends a notification to a mobile app. If the individual does not cancel the rescue process within 30 seconds, the device releases naloxone stored inside, counteracting the overdose effects. To further enhance safety, the Naloximeter also sends an alert to emergency responders, ensuring professional help arrives even if the initial intervention is successful.</p><p class=\"reg-normal\">In animal studies, the Naloximeter performed remarkably well. When implanted in the neck, chest, or back, it detected signs of overdose within a minute, delivering naloxone that led to full recovery in all cases within five minutes.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Why Immediate Intervention Matters</h2><p class=\"reg-normal\">Naloxone reverses the effects of opioids by displacing them from receptors in the brain, but its effects don’t last long. If opioids re-enter the receptors after naloxone wears off, overdose symptoms can return.

It marked a pivotal evolutionary shift, as the ancestors of today’s land animals crawled out of the water and began exploring new terrains about 390 million years ago. But how exactly did those early creatures manage to move from swimming to walking? With fossil evidence providing only a fragmented view, a team of researchers is turning to an unlikely ally: robots.</p><p class=\"reg-normal\">In a study published in Science Robotics, a collaborative team of roboticists, palaeontologists, and biologists from the University of Cambridge is pioneering the use of \"palaeo-inspired robotics\" to simulate the movements of ancient fish. Their goal? To better understand how fins evolved into limbs capable of supporting weight on land.</p><p class=\"reg-normal\">Lead researcher Dr. Michael Ishida from Cambridge\'s Department of Engineering explains the challenge: \"Fossils only give us a partial picture of how ancient species made their move to land. We can learn a lot from studying their bones, but bones alone don’t reveal how these creatures moved. That’s where our robots come in – helping us simulate the movements and behaviors of species that have long since disappeared.\"</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Robots Bridging the Gap</h2><p class=\"reg-normal\">At Cambridge\'s Bio-Inspired Robotics Laboratory, Professor Fumiya Iida and his team are developing energy-efficient robots inspired by the movement of animals. With the support of the Human Frontier Science Program, they\'re taking cues from modern \"walking fish\" like mudskippers and combining them with data from fossilized remains of ancient species.</p><p class=\"reg-normal\">The process involves creating robotic skeletons that replicate the anatomy of these early fish. \"In the lab, we can’t exactly teach a living fish to walk differently, and we certainly can’t ask a fossil to get up and move,\" says Ishida. \"Instead, we build robotic models that mimic their skeletal structures, complete with mechanical joints that act like muscles and ligaments.\"</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Simulating Ancient Movement</h2><p class=\"reg-normal\">The team aims to use these robots to run experiments that shed light on the locomotion of early land explorers. One of their key objectives is to analyze the energy requirements of different walking patterns, testing which movements might have been the most efficient. This approach can help validate or challenge existing theories about how these ancient animals evolved.</p><p class=\"reg-normal\">The robotic models also provide a new way to address the limitations of fossil records. Since many ancient species from this time period are only known from partial skeletons, scientists often have to make educated guesses about their mobility. Robots allow researchers to test these assumptions and refine their understanding of how early vertebrates moved.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">An Emerging Field</h2><p class=\"reg-normal\">Using robots to study extinct species is a relatively new field of research. While robotics has long been used to understand the movement of living animals, very few research groups have applied this technology to the biomechanics of ancient life forms. \"It\'s a natural fit, though,\" says Ishida. \"Robots can offer insights that we just can\'t get from studying fossils or living species alone.\"</p><p class=\"reg-normal\">By bridging the gap between fossil evidence and real-world mechanics, the researchers hope their work will inspire other scientists to explore robotics as a tool for studying ancient life. The potential goes beyond evolutionary biology – the approach could also foster new collaborations between engineers and researchers in fields like palaeontology, biomechanics, and robotics.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Looking Ahead</h2><p class=\"reg-normal\">The project is still in its early stages, with the team currently building their palaeo-robots. However, they aim to have preliminary results within a year. The researchers are optimistic that their robotic models will deepen our understanding of the evolutionary shift from water to land and potentially uncover why these early land pioneers moved the way they did.</p><p class=\"reg-normal\">The research is supported by the Human Frontier Science Program, with Professor Fumiya Iida serving as the senior author and Dr. Michael Ishida as a postdoctoral researcher. Their innovative use of robotics might just help answer one of the oldest questions in evolutionary history – how the first creatures made the leap to land, paving the way for all terrestrial life that followed.</p>','2024-10-25 05:14:59.541082','uploads/news/images_8.jpeg',1,'University of Cambridge','Researchers from the University of Cambridge are using \"palaeo-inspired robotics\" to study how ancient fish transitioned from swimming to walking roughly 390 million years ago.

This tiny marvel, named Heleocola piceanus (which fittingly means “swamp dweller”), lived about 70 to 75 million years ago. A team led by Jaelyn Eberle from the University of Colorado Boulder identified the creature from its jawbone and three distinctive molar teeth, published on October 23 in PLOS ONE.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Colorado\'s Rare Fossil Find</h2><p class=\"reg-normal\">While the towering dinosaurs of the Cretaceous tend to steal the spotlight, the discovery of H. piceanus sheds light on the less famous, but equally fascinating, ancient mammals that shared this world. Colorado is known for its fossil wealth, yet mammals from this era are exceptionally rare. As Eberle, a paleontologist and curator at CU Museum of Natural History, explained, “It’s really neat to see this slice of time preserved in Colorado.” Compared to the giants that roamed at the time—like tyrannosaurs and horned dinosaurs—this little mammal may seem insignificant, but it was a giant among its kind.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">A Window to an Ancient Swamp</h2><p class=\"reg-normal\">Picture a Colorado that looked more like the bayous of Louisiana than the mountainous landscapes we see today. The area was a patchwork of marshes and estuaries where land met water, providing an ideal habitat for an array of creatures. Giant crocodiles lurked in the swamps, turtles basked in the sun, and duck-billed dinosaurs wandered the wetlands. Even sharks and rays swam in the waterways. “The region might have looked kind of like Louisiana,” said ReBecca Hunt-Foster, a paleontologist based at Dinosaur National Monument.</p><p class=\"reg-normal\">For over 15 years, Hunt-Foster and her colleague John Foster have been searching this region for fossils, but it was in 2016 that a truly unique find emerged. The bit of jawbone they discovered seemed enormous for a mammal of the Late Cretaceous, which were typically the size of modern-day mice or rats. Foster recalls being struck by the find, saying, “I said, ‘Holy cow, that’s huge.’”</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">A Giant Among Ancient Mammals</h2><p class=\"reg-normal\">Although small by today’s standards, H. piceanus was larger than most of its contemporaries, weighing around 2 pounds—about the size of a muskrat. In the era before an asteroid wiped out the non-avian dinosaurs 66 million years ago, mammals were usually small, and their fossils often consist of little more than tiny teeth. H. piceanus, in comparison, was a giant. The fossil’s teeth suggest it likely enjoyed a mixed diet of plants, insects, and perhaps other small creatures. This discovery hints that some mammals in the Late Cretaceous were larger and more diverse than previously thought.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">A Treasure Trove for Paleontologists</h2><p class=\"reg-normal\">The discovery of H. piceanus adds to the growing list of significant finds from the Mountain West, a region celebrated by scientists worldwide for its fossil wealth. “We have scientists that come from all over the world specifically to study our fossils,” Hunt-Foster noted, emphasizing the importance of protecting these ancient treasures. She advises that anyone who encounters a fossil while hiking should refrain from collecting it, as these remains hold vital scientific information. Instead, she recommends documenting the location, snapping a photo, and reporting the find to a local museum or land agency.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">The Significance of Small Discoveries</h2><p class=\"reg-normal\">While it’s easy to be dazzled by the colossal remains of dinosaurs, the discovery of H. piceanus reminds us that even the smallest creatures played crucial roles in their ecosystems. “They’re not all tiny,” Eberle remarked, reflecting on how recent findings are challenging the old image of small, unimpressive mammals scurrying around dinosaur feet. As paleontologists continue to explore the fossil-rich lands of western Colorado, more surprises are likely hiding just beneath the surface.</p><p class=\"reg-normal\">The discovery of this ancient “swamp dweller” not only enriches our understanding of Colorado’s prehistoric past but also adds another chapter to the story of life before the dinosaurs met their untimely end.</p>','2024-10-25 05:40:45.872887','uploads/news/images_9.jpeg',1,'University of Colorado at Boulder','A team of paleontologists has uncovered a rare fossil mammal named Heleocola piceanus in northwest Colorado, dating back 70 to 75 million years.

The research, conducted by experts from Monash University’s Centre for Learning Analytics (CoLAM), the University of Luxembourg, and Goethe-University Frankfurt, explores how AI can be integrated to support human learning while addressing the ethical, practical, and social challenges it presents.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Harnessing GenAI for Learning Innovation</h2><p class=\"reg-normal\">As GenAI tools rapidly evolve, they are poised to reshape how we learn, work, and interact. Professor Dragan Gasevic, Director of CoLAM and the senior author of the paper, envisions a future where AI goes beyond automating tasks to becoming a true partner in education. \"Imagine students engaging in debates with digital twins of Socrates to explore ancient Greek philosophy, learning impressionist painting techniques from a humanoid robotic mentor modelled after Claude Monet, or visualising Einstein\'s special theory of relativity in virtual realities,\" Gasevic said, illustrating the profound potential of AI-enhanced learning experiences.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">A Dual Approach to Learning</h2><p class=\"reg-normal\">The study advocates for a dual learning approach: educating individuals not only with GenAI but also about it. This means equipping students, teachers, and policymakers with the knowledge and skills to critically engage with AI while leveraging its capabilities for deeper learning experiences. The researchers argue that for GenAI\'s potential to be fully realized, unified efforts across educational institutions, technology developers, and government agencies are essential.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Supporting Teachers in the GenAI Era</h2><p class=\"reg-normal\">One of the core challenges identified is supporting educators as they adapt to the new GenAI landscape. Dr. Lixiang Yan, CoLAM Research Fellow and the study\'s first author, noted that GenAI could shift teachers\' roles from traditional knowledge dissemination to more personalized mentorship and facilitation. \"Educational institutions must invest in ongoing professional development and support systems to help teachers manage techno-stress and workload burdens from adopting these new technologies,\" Yan said. Training programs must focus on enhancing AI literacy to ensure teachers and students can effectively use these tools for learning.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Ethics and Accountability in AI Integration</h2><p class=\"reg-normal\">While GenAI offers new avenues for learning, it also brings ethical challenges related to transparency, privacy, and equality. The researchers stress the importance of developing ethical guidelines to ensure that AI tools in education are used responsibly. Accountability measures should be put in place to prevent over-reliance on AI-generated content and to foster genuine learning and skill development.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Reshaping Assessments for the Age of AI</h2><p class=\"reg-normal\">The study highlights the need for assessment processes that prioritize authentic knowledge and skill improvement over AI-generated results. This calls for innovative approaches to evaluating student performance, ensuring that assessments measure real understanding rather than the ability to navigate AI tools. The researchers are also working on projects aimed at assessing human-AI collaborative writing and improving knowledge-sharing practices among educators.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Global Collaboration and Research Initiatives</h2><p class=\"reg-normal\">Supported by the Australian Research Council and other prominent organizations, CoLAM experts are conducting groundbreaking research worldwide.

This innovative device addresses the pressing need for scalable, cost-effective solutions to reduce atmospheric CO₂ emissions, with potential to become a cornerstone of future climate mitigation efforts.&nbsp;</p><p><br></p><p class=\"reg-normal\">In a study published in *Nature Energy*, the team describes a reactor design with a modular, three-chamber structure centered on a porous solid electrolyte layer. Haotian Wang, a Rice University chemical and biomolecular engineer leading the study, called it “a big milestone in carbon capture from the atmosphere,” emphasizing its relevance for industrial applications. “Our research findings present an opportunity to make carbon capture more cost-effective and practically viable across a range of industries,” Wang noted, underscoring the technology’s versatility and wide-scale potential.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">How It Works: Innovative Reactor Design&nbsp;</h2><p class=\"reg-normal\">The reactor has achieved impressive rates of carbon dioxide regeneration, demonstrating stability and adaptability with various cathode and anode reactions. Wang highlighted the technology\'s unique flexibility, explaining that it can operate with multiple chemistries and even coproduce hydrogen—an advantage that could significantly lower capital and operational costs for industries transitioning to net-zero fuels and chemicals.&nbsp;</p><p class=\"reg-normal\">Unlike conventional direct air capture methods, which require high temperatures to extract CO₂ from mixed gas streams, Rice’s electrochemical approach bypasses these energy-intensive steps. Traditional systems filter CO₂ by running a gas stream through high-pH liquids, creating bonds that require substantial heat, chemicals, or additional electrochemical processes to break. In contrast, this new reactor uses electrical energy instead of thermal energy, functioning at room temperature, eliminating the need for added chemicals, and generating no harmful byproducts.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">The Challenge of CO₂-Trapping Chemicals&nbsp;</h2><p class=\"reg-normal\">Capturing carbon dioxide from air typically requires sorbents that chemically bind with CO₂. Amine-based sorbents, popular for their energy-efficient bond breaking, are toxic and less stable. Water-based solutions, which are greener, require higher temperatures for CO₂ release. The Rice team’s design offers a better alternative, efficiently separating carbonates and bicarbonates into an alkaline absorbent and high-purity CO₂, using optimized electrical inputs to control ion movement and minimize energy costs.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Looking Ahead</h2><p class=\"reg-normal\">Wang hopes this breakthrough will motivate more industries to adopt sustainable practices, fueling momentum toward a net-zero future. \"Rice is the place to be if you are passionate about sustainability and energy innovation,\" he said.

However, scientists at the Buck Institute for Research on Aging have leapfrogged this standard approach using advanced machine learning and systems biology to analyze large-scale data from both flies and humans. This new method, detailed in a *Nature Communications* publication, has already revealed significant findings, including the potential of threonine, an essential amino acid, as a candidate for therapeutic interventions to promote healthy aging.&nbsp;</p><p class=\"reg-normal\">“This would not have been possible without this pioneering approach,” said Pankaj Kapahi, PhD, a senior author on the study. “There is a lot of data sitting out there that is not being correlated between species.

Threonine contributes to essential functions like collagen and elastin production, blood clotting, fat metabolism, and immune response. When tested, the amino acid extended the lifespan of flies, but the effects varied based on specific genetic and biological traits, hinting at its potential for personalized medicine approaches.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Data-Driven Approach: How the Study Worked</h2><p class=\"reg-normal\">The study began with Tyler Hilsabeck, PhD, a former postdoc at the Buck Institute, who analyzed metabolomic, phenotypic, and genomic data from 160 fruit fly strains on both restricted and regular diets, evaluating over 120 metabolites. “This allowed us to find the ‘needles in the haystack’ in terms of identifying metabolites that might impact lifespan and healthspan,” Hilsabeck explains.</p><p class=\"reg-normal\">Following this, postdoctoral fellow Vikram Narayan, PhD, cross-referenced the fly data with human data from the extensive UK Biobank. This cross-species comparison identified common metabolites with similar effects, including threonine, which appeared beneficial, and orotate, which was associated with shorter lifespan. The team further tested these metabolites in flies, confirming the initial findings.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Key Findings and Larger Implications</h2><p class=\"reg-normal\">The research found that threonine extended lifespan in a strain-specific way, showing potential in both flies and humans. However, not all results were positive: Orotate, a metabolite linked to fat metabolism, counteracted lifespan extension benefits in flies on restricted diets and correlated with shorter lifespans in humans.</p><p class=\"reg-normal\">\"We’re not saying threonine will work in all conditions,\" Kapahi clarifies. \"Our research shows it works in subsets of both flies and people. We no longer expect a \'magic-bullet\' solution for aging, and our method offers a precision approach to geroscience.”</p><p class=\"reg-normal\">Kapahi is hopeful that the wider scientific community will adopt this methodology, reducing the need for mice studies and advancing basic aging research. \"Many promising findings in flies and worms don’t make it to human studies due to limited resources.

These beetles, while diverse in function, from pollination to decomposition, also include species notorious for crop and forest damage. Utilizing x-ray microtomography, a cutting-edge imaging technique that allows scientists to see intricate internal structures without damage, Lewis and his team uncovered new insights into weevil morphology and taxonomy.</p><p class=\"reg-normal\">This technique enabled the researchers to digitally ‘peel back’ the scales of weevils to view their underlying cuticle structure, revealing significant differences between species that had previously been challenging to classify. Using a combination of microtomography, traditional light microscopy, and DNA barcoding, the team identified and named 12 new weevil species from Japan, Malaysia, Vietnam, and Taiwan. Among these discoveries are two new species in Japan, including *Aphanerostethus magnus* and *Aphanerostethus japonicus*—the latter inhabiting Okinawa’s Yanbaru National Park.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Novel Taxonomy Techniques</h2><p class=\"reg-normal\">The use of x-ray microtomography for examining and distinguishing weevil species marks a first in the field, providing taxonomists with a tool to analyze the morphology of beetles hidden under scales or debris. Traditional approaches like light microscopy and dissection were also employed to examine specific physical traits, including leg spines, elytra scales, and rostral canal shape. DNA barcoding supplemented these findings, allowing for genetic analysis and construction of a phylogenetic tree, which confirmed the species\' classifications.</p><p class=\"reg-normal\">One notable discovery pertains to the weevils’ hindwings: species within the genus *Aphanerostethus* have progressively lost their wings. X-ray microtomography enabled the team to examine these vestigial wings without invasive dissection, uncovering a fascinating glimpse into evolutionary biology. Some species have almost entirely lost their wings, while others retain partially developed, non-functional wings. \"The varying degrees of hindwing reduction among these species not only help in taxonomy but also reveal different stages of a key evolutionary adaptation,\" Lewis explained.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Preserving Japan\'s Biodiversity</h2><p class=\"reg-normal\">Lewis’ work highlights the immense challenge of studying weevil diversity.

Traditionally, clinicians rely on specific molecules in tumors, known as predictive biomarkers, to gauge potential treatment response. However, according to senior author Dr. Aleksander Popel, a professor of biomedical engineering and oncology, these biomarkers often lack the accuracy needed to guide treatment decisions for many patients, particularly for those with complex cancer types.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Leveraging Computational Models for Predictive Accuracy</h2><p class=\"reg-normal\">To address this, the Johns Hopkins team utilized a quantitative systems pharmacology model to simulate 1,635 ‘virtual patients’ with metastatic triple-negative breast cancer. These virtual profiles allowed the researchers to test immunotherapy drug responses and analyze 90 different biomarkers using advanced machine learning and statistical techniques. Notably, their model highlighted two categories of biomarkers with promising predictive power: on-treatment biomarkers, measured after therapy begins, and early tumor response metrics such as changes in tumor diameter.</p><p class=\"reg-normal\">Interestingly, the team found that measuring changes in tumor diameter within the first two weeks of treatment could significantly enhance predictive accuracy. \"This metric, which can be captured through standard CT scans, holds great potential in early identification of responders,\" Popel said. In a virtual trial based on early tumor diameter changes, the simulated response rates doubled, from 11% to 25%, suggesting a noninvasive way to monitor treatment efficacy without requiring invasive biopsies.</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Redefining Biomarker Assessment for Broader Application</h2><p class=\"reg-normal\">The team’s findings could redefine how biomarkers are assessed in other cancers. For instance, while certain markers like PD-L1 levels and lymphocyte presence in tumors provided valuable pretreatment data, the study found these markers were more accurate when measured before treatment rather than during. This discovery suggests that a combination of biomarker measurements taken at multiple points may be more effective in predicting outcomes.</p><p class=\"reg-normal\">\"Using computational modeling to examine these biomarker interactions helps us understand patient-specific responses better, especially in cases where traditional methods fall short,\" said Dr. Cesar Santa-Maria, a breast cancer immunotherapy expert at Johns Hopkins and study co-author. Santa-Maria added that noninvasive biomarkers could serve as alternatives where biopsy collection is challenging, helping avoid overtreatment in patients likely to do well without immunotherapy.</p><p class=\"reg-normal\">The researchers plan to apply their findings to future clinical trials, with hopes that this method could become a model for biomarker assessment across various cancer types.

This approach has particular relevance in the context of rheumatoid arthritis, an autoimmune disease that causes chronic pain, stiffness, and tissue damage, affecting 18 million people worldwide, including 456,000 Australians.</p><p class=\"reg-normal\">Though RA management has improved with biologic treatments, many patients still face considerable physical and mental challenges, with around 35% experiencing conditions like anxiety, depression, or mood disorders. Dr. Mittinty emphasized the impact of dyadic coping, noting that “supportive dyadic coping is linked to lower levels of depression, anxiety, and stress, as well as enhanced relationship quality, while negative coping behaviors can exacerbate psychological distress for both partners.”</p><h2 class=\"mt-4 mb-4 text-3xl font-extrabold tracking-tight text-gray-900 dark:text-white\">Study Findings and the Importance of Partner Perspectives</h2><p class=\"reg-normal\">The study surveyed 163 couples, incorporating both RA patients and their spouses, who completed assessments on their experiences of pain, coping, stress, and relationship satisfaction.

Wolff Distinguished Professor of Pathology &amp; Immunology, emphasized the significance of these findings: “We have discovered guardian brain peptides that actively engage with the immune system, potentially preventing harmful immune responses.” This research holds promise for enhancing treatments for various neuroinflammatory diseases, including multiple sclerosis (MS) and Alzheimer\'s disease.&nbsp;</p><p class=\"reg-normal\">Immune surveillance relies on T cells that respond to threats by recognizing tiny protein fragments presented by specialized immune cells. The study revealed that guardian peptides are displayed at the brain’s borders, attracting regulatory T cells that help suppress abnormal immune reactions. Min Woo Kim, a graduate student and researcher in Kipnis’s lab, investigated these immune cells in healthy mice and found that a key protein involved in myelin sheath integrity, which is often damaged in MS, was presented abundantly. However, in mice with MS, these proteins were significantly reduced.&nbsp;</p><p class=\"reg-normal\">To address this, the researchers injected vesicles containing the missing brain-derived peptides into the cerebrospinal fluid of MS-afflicted mice. This treatment successfully activated and expanded a subset of suppressor T cells, leading to improved motor function and slowed disease progression compared to control mice.&nbsp;</p><p class=\"reg-normal\">Kim noted, “We have identified a novel mechanism where the brain engages with the immune system to present a healthy representation of itself. In the case of MS, this representation is altered. We believe that other neuroinflammatory and neurodegenerative diseases may also exhibit distinct protein signatures that could serve as diagnostic markers.”&nbsp;</p><p class=\"reg-normal\">The study also involved contributions from other WashU Medicine researchers, including Cheryl Lichti, Clair Crewe, and Maxim N.

Their study, published in the *American Journal of Psychiatry* on October 30, highlights new clusters of cells with distinct gene expression patterns in the amygdala of humans and non-human primates, paving the way for more targeted treatments for anxiety and related disorders that affect millions.&nbsp;</p><p class=\"reg-normal\">Drew Fox, associate professor in the UC Davis Department of Psychology, emphasized the amygdala\'s central role in emotion but pointed out that its overall size and structure are not reliable predictors of emotional disorders. Previous research in rodents revealed that different cell types within the amygdala\'s subregions have unique and sometimes opposing functions, suggesting that specific alterations in these cell types could contribute to the emergence of disorders like anxiety and depression.&nbsp;</p><p class=\"reg-normal\">Graduate student Shawn Kamboj led a collaboration to identify these cell types in both human and rhesus macaque amygdalae by analyzing gene expression patterns. By employing single-cell RNA sequencing, the team isolated individual cells from brain samples and sequenced their RNA, revealing active genes and allowing for the classification of cells based on their gene expression.&nbsp;</p><p class=\"reg-normal\">One significant finding was the identification of cells expressing the FOXP2 gene, located in the intercalated cells at the edges of the amygdala. In rodent models, these cells are known as “gatekeepers” that regulate the flow of signals in and out of the amygdala, making them a promising target for developing new treatments.&nbsp;</p><p class=\"reg-normal\">The study also uncovered both similarities and differences in cell types between humans and non-human primates, enhancing our understanding of how animal models can inform human psychiatric disorders. Notably, FOXP2-expressing cells also exhibited anxiety-related gene expression and contained a receptor, Neuropeptide FF Receptor 2 (NPFFR2), which is a potential drug target. This discovery could guide the development of new treatment strategies by suggesting drugs that activate the NPFFR2 pathway for addressing anxiety-related disorders.&nbsp;</p><p class=\"reg-normal\">As anxiety disorders can manifest in various forms, identifying the specific cell types involved may allow researchers to pinpoint critical “chokepoints” that affect many individuals suffering from debilitating anxiety.

Project CETI (Cetacean Translation Initiative) is on a mission to make that a reality by collecting millions, if not billions, of high-quality vocalizations from these magnificent creatures. But here’s the catch: tracking sperm whales is no easy feat. Knowing where they will surface is like trying to predict the weather; it requires a lot of guesswork and precision.</p>\r\n\r\n\r\n<p class=\"reg-normal\">Today, a research team led by Stephanie Gil, an Assistant Professor of Computer Science at Harvard\'s John A. Paulson School of Engineering and Applied Sciences (SEAS), has introduced an innovative solution. They proposed a groundbreaking reinforcement learning framework that employs autonomous drones to locate and predict the surface behavior of sperm whales. This exciting research has just been published in *Science Robotics*.</p>\r\n\r\n\r\n<p class=\"reg-normal\">The team is utilizing advanced sensing technology, specifically aerial drones equipped with very high frequency (VHF) signal sensing capabilities. These drones can analyze signals from the tags attached to the whales, functioning like an \'antenna array in the air.\' This technology allows them to estimate the direction from which the whales\' vocalizations are coming, giving researchers valuable insights into their communication patterns. By combining sensor data with predictive models of sperm whale dive behavior, they can forecast when and where a whale is likely to surface. This knowledge is crucial for optimizing the drone\'s route to maximize encounters with these oceanic mammals.</p>\r\n\r\n\r\n<p class=\"reg-normal\">Not only does this research enhance our understanding of sperm whales, but it also has potential conservation applications. By knowing where whales are likely to surface, we can develop strategies to help ships avoid collisions with these majestic animals. The study introduces the Autonomous Vehicles for whAle Tracking And Rendezvous by remote Sensing (AVATARS) framework, which harmonizes two essential components: autonomy, which dictates the drone\'s movements, and sensing, which measures the Angle-of-Arrival (AOA) from whale tags to guide decision-making.</p>\r\n\r\n\r\n<p class=\"reg-normal\">The AVATARS framework takes measurements from the drones and existing underwater sensors to inform its autonomous decision-making algorithm, striving to minimize missed opportunities to rendezvous with whales. This innovative approach parallels rideshare apps, which use real-time data to efficiently match drivers with passengers. Similarly, Project CETI tracks whales in real-time, aiming to coordinate the drone\'s rendezvous with the whale as it surfaces.</p>\r\n\r\n\r\n<p class=\"reg-normal\">As the research unfolds, it brings Project CETI closer to its ambitious goal of collecting vast amounts of whale vocalizations. With a diverse array of data at their disposal, the team can refine their location estimates and routing algorithms, paving the way for more efficient data collection.</p>\r\n\r\n<p class=\"reg-normal\">“I’m thrilled to contribute to this breakthrough for Project CETI. By leveraging autonomous systems and advanced sensor integration, we’re tackling key challenges in tracking and studying whales in their natural habitats,” said Gil. “This is not just a technological leap; it’s a vital step toward understanding the intricate communications and behaviors of these magnificent creatures.”</p>\r\n\r\n\r\n<p class=\"reg-normal\">David Gruber, the Founder and Lead of Project CETI, expressed similar enthusiasm: “This research marks a significant milestone for our mission. We can now significantly enhance our capacity to gather high-quality datasets on whale vocalizations and their behavioral context, bringing us closer to interpreting what sperm whales are really saying.”</p>\r\n\r\n\r\n<p class=\"reg-normal\">Ninad Jadhav, a PhD candidate at Harvard and the paper’s first author, noted, “This project was an incredible opportunity to test our systems in a challenging marine environment. Our interdisciplinary approach combines wireless sensing, artificial intelligence, and marine biology, showcasing how robotics can help us unravel the social behaviors of sperm whales.”</p>\r\n\r\n\r\n\r\n<p class=\"reg-normal\">Sushmita Bhattacharya, a postdoctoral researcher in Gil\'s REACT Lab at SEAS, added, “This project is a fantastic chance to apply our algorithms in the field, where robotics and artificial intelligence can enhance data collection and accelerate research in language processing and marine biology, ultimately contributing to the preservation of sperm whales and their habitats.”</p>\r\n\r\n\r\n\r\n<p class=\"reg-normal\">For more information on Project CETI and its groundbreaking work, you can visit [Project CETI](https://www.projectceti.org/).</p>','2024-11-02 07:26:17.846333','uploads/news/images_39.jpeg',1,'Harvard John A.

A new study has revealed that cognitive behavioral therapy for insomnia (CBTi) can not only enhance sleep patterns for expectant mothers but also help combat postpartum depression. Researchers from the University of British Columbia’s (UBC) Okanagan and Vancouver campuses, alongside colleagues from the University of Calgary, discovered something remarkable: implementing CBTi during pregnancy can significantly reduce depressive symptoms after childbirth.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">\"Early intervention is crucial for infant and parental mental health,\" explains Dr. Elizabeth Keys, an Assistant Professor in UBCO\'s School of Nursing and a co-author of the study. \"Our research delves into how tackling sleep issues like insomnia can lead to improved mental health outcomes for families, ultimately helping both parents and their children thrive.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">So, what exactly is CBTi? It’s a therapeutic approach designed to identify the thoughts, behaviors, and sleep patterns that contribute to insomnia. The treatment involves challenging misconceptions about sleep and restructuring habits to enhance overall sleep quality. As Dr. Keys puts it, \"CBTi is the gold standard for insomnia treatment and has consistently demonstrated effectiveness in alleviating depressive symptoms.\" In fact, its benefits are comparable to those of antidepressant medications for adults, but with fewer side effects, making it a preferred option for many pregnant individuals.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">In their study, sixty-two women who were assessed for insomnia and depressive symptoms participated, with half receiving the intervention and the other half placed in a control group. \"We found that CBTi during pregnancy significantly improved sleep and reduced postpartum depressive symptoms for participants,\" Dr. Keys explains. \"These findings are incredibly encouraging for anyone who has faced sleepless nights in those early weeks and months with a newborn.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The results suggest that effectively treating insomnia during pregnancy may serve as a protective factor against postpartum depression.

It turns out, there’s a fascinating science behind this rapid adaptation. Researchers at Johannes Gutenberg University Mainz (JGU) have unveiled the neuronal networks and mechanisms that enable animals to perceive contrasts reliably, even as light levels fluctuate dramatically.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Professor Marion Silies, who led the study, explains, \"In these situations, it’s not enough for the photoreceptors in our eyes to adapt; we also need an additional corrective mechanism.\" Her team previously identified a corrective mechanism known as \'gain control\' in the fruit fly, *Drosophila melanogaster*, which operates just downstream of the photoreceptors. Their latest research, published in *Nature Communications*, details the algorithms and neuronal circuits that allow these flies to maintain stable visual processing despite rapid changes in light.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">So, why is stable visual processing so crucial? Our vision must function accurately in a variety of contexts—whether we are navigating through our environment or tracking an object that moves from light to shadow. This ability is essential not only for humans but also for thousands of animal species that depend on sight for navigation. Interestingly, self-driving cars face similar challenges with fluctuating light conditions, often relying on radar or lidar technology to maintain accurate contrast detection. Silies and her team sought to understand how animals achieve this naturally, without any technological aids.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Combining theoretical and experimental methods, the researchers studied the compound eyes of fruit flies, which are composed of about 800 individual units known as ommatidia. The contrast between an object and its background is determined in the visual circuitry behind the photoreceptors. When lighting conditions change suddenly—like when an object moves into the shadow of a tree—contrast responses can vary dramatically. Without gain control, these differences would disrupt subsequent stages of visual processing, causing the object to appear differently than it should.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">In the study, led by Dr. Burak Gür, the team utilized two-photon microscopy to pinpoint where stable contrast responses are first generated within the visual circuitry. They identified specific neuronal cell types located just two synapses away from the photoreceptors. These cells only respond locally to visual information. To accurately compute contrast, background luminance information requires narrow spatial pooling, a concept further explored through computational modeling by co-author Dr. Luisa Ramirez.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Silies shares, \"We started with a theoretical approach that predicted an optimal radius for capturing background luminance across specific regions in visual space, while simultaneously searching for a cell type that could facilitate this process.\" Eventually, they discovered a cell type, designated Dm12, that pools luminance signals over a defined radius, effectively correcting the contrast response even in rapidly changing light conditions.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">In conclusion, the Mainz-based neuroscientists have unraveled the algorithms, circuits, and molecular mechanisms that allow vision to remain stable amidst rapid luminance shifts. Silies, who has dedicated over 15 years to studying the visual system of fruit flies, suggests that similar mechanisms for luminance gain control likely exist in mammals, including humans, given the availability of the necessary neuronal substrates.</p>','2024-11-02 07:54:09.141421','uploads/news/images_l0JSsxC.jpeg',1,'Johannes Gutenberg Universitaet Mainz','New research from Johannes Gutenberg University Mainz reveals how neuronal networks in fruit flies enable stable visual processing under rapidly changing light conditions.

However, these critical immune responders can mistakenly identify beneficial biotechnologies as threats. If biotechnological devices are not crafted from the appropriate materials or designed with the right mechanical forces, they can trigger an adverse immune response, leading to inflammation, scar tissue formation, or device failure.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The question arises: What constitutes the right material or mechanical force? In a recent meta-analysis co-led by Dr. Abigail Clevenger, a biomedical engineering graduate student at Texas A&amp;M University, researchers stress the importance of context. Dr. Shreya Raghavan, a co-author and assistant professor in biomedical engineering, explains, \"Not any one force has the same effect on macrophages throughout the body. For instance, macrophages in the lungs, which experience inflation and deflation, are adapted to those mechanical forces. In contrast, macrophages in the uterus or gut will have different adaptations.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Clevenger, now a postdoctoral fellow, collaborated on this study with Dr. Aakanksha Jha from the University of Maryland. The article, published in *Trends in Biotechnology*, emphasizes the necessity of comprehending macrophage behavior to potentially pave the way for enhanced biotechnologies and targeted immunotherapy treatments.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Raghavan notes that when designing immunotherapy for conditions like colorectal cancer, one cannot merely create a solution in a lab dish devoid of mechanical considerations. \"Mechanics influence how macrophages behave. Your design solutions must recognize that these cells are mechanosensitive. Failing to do so risks the chance that macrophages, which can aid in device functionality, may mistakenly perceive harmful tumors as allies, allowing them to thrive,\" she warns.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The review meticulously summarizes significant research advancements regarding the interactions between biotechnologies and macrophages over the past four years. Raghavan emphasizes the remarkable progress made: \"Just five years ago, there was a substantial knowledge gap. Now, with integrated tools from biomedical engineering to molecular and computational biology, we have an abundance of data to analyze. It\'s beautiful.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">On a personal note, Raghavan shares her experience with a continuous glucose monitor, which she replaces every two weeks due to the immune system\'s reaction to the foreign materials affecting its readings.

However, many of these invaluable artworks have deteriorated over time. While modern 3D scanning and photogrammetry can preserve their current forms, they cannot restore the original appearance of these carvings. Conventional restoration techniques are laborious, further complicating the process.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">To address this, researchers have turned to the 3D digital reconstruction of reliefs using historic photographs taken before the damage occurred. Unlike traditional 3D sculptures or 2D paintings, reliefs are designed to be viewed from the front or sides, allowing a single image to provide most of the information required for effective reconstruction.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">In a significant advancement, a multinational research team led by Professor Satoshi Tanaka from Ritsumeikan University in Japan, alongside Dr. Jiao Pan from the University of Science and Technology Beijing, has developed an innovative multi-task neural network that facilitates this 3D reconstruction and digital preservation. \"Previously, our team proposed a method based on monocular depth estimation from photos, achieving 95% reconstruction accuracy. However, finer details like human faces were often missing due to high compression of depth values in 2D relief images. Our new method enhances depth estimation, particularly around soft edges, using a novel edge-detection approach,\" explains Prof. Tanaka.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">This collaborative effort also included Prof. Liang Li from Ritsumeikan University and Prof. Xiaojuan Ban from the University of Science and Technology Beijing. Their findings were presented at the ACM Multimedia 2024 conference in Australia and published in the conference proceedings.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The proposed multi-task neural network performs three interconnected tasks: semantic segmentation, depth estimation, and soft-edge detection. This trio works in concert to improve the accuracy of the 3D reconstruction. The core strength of the network lies in its depth estimation, achieved through an innovative soft-edge detector and an edge matching module. Rather than treating edge detection as a binary classification task, the soft-edge detector classifies edges in relief images as multi-class entities. This approach recognizes that edges represent not only changes in brightness but also variations in curvature, referred to as \"soft edges.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">By assessing the degree of softness of these edges, the network enhances depth estimation. The edge matching module employs two soft-edge detectors to extract multi-class soft-edge maps alongside a depth map from the input relief photo. This matching process hones in on soft-edge regions, leading to more detailed depth estimation. Additionally, the network optimizes a dynamic edge-enhanced loss function, incorporating loss from all three tasks to produce clear, detailed 3D images of reliefs.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The researchers applied this innovative model to reconstruct hidden reliefs at the Borobudur Temple, a UNESCO World Heritage Site in Indonesia. \"The ground-level wall reliefs of Borobudur are obscured by stone walls due to reinforcement work conducted during the Dutch colonial period, rendering them invisible.

Shungo Koyama from Tohoku University explains, \"Ancient Earth was nothing like our current home. It was a much more hostile environment, rich in metallic iron and characterized by an atmosphere laden with hydrogen and methane.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">These molecular compounds hold essential clues to the origins of life. When exposed to solar ultraviolet (UV) radiation, they engage in chemical reactions that yield organic compounds, which serve as the fundamental building blocks of life. Among these organic compounds are precursors to vital biomolecules, including amino acids and nucleic acids.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">However, understanding the impact of UV radiation on these early atmospheric conditions presents challenges. The atmosphere of ancient Earth was likely unstable and subject to rapid fluctuations due to various atmospheric chemical reactions. Additionally, UV radiation breaks down water vapor, creating oxidative molecules, but the specific branching ratios and timescales of these reactions remain uncertain.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">To tackle these complexities, the researchers developed a one-dimensional photochemical model to accurately simulate the ancient Earth’s atmosphere. Their calculations revealed that most hydrogen escaped into space while hydrocarbons like acetylene, produced from methane, acted as a shield against UV radiation. This shielding effect significantly reduced the breakdown of water vapor and the subsequent oxidation of methane, thereby enhancing the production of organics.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Tatsuya Yoshida of Tohoku University suggests, \"If the initial amount of methane was comparable to the carbon content found on present-day Earth’s surface, organic layers several hundred meters thick could have formed. This could have led to the accumulation of organics, creating an enriched ‘soup’ of essential building blocks from which life may have first emerged.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Interestingly, the model indicates that the atmosphere of ancient Earth bore striking similarities to the conditions we observe on neighboring planets, Venus and Mars. Despite their proximity, Earth has developed into a vastly different environment, prompting researchers to explore what sets our planet apart. This model not only enhances our understanding of Earth\'s atmospheric evolution but also raises questions about the common patterns shared by other planetary systems in their journey toward life.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The findings contribute valuable insights into whether the atmospheric evolution and origins of life on Earth are unique or if they resonate with processes occurring elsewhere in the cosmos.</p>','2024-11-02 07:56:44.260883','uploads/news/images_37.jpeg',1,'Tohoku University','A new model from researchers at Tohoku University and others explores the evolution of Earth\'s atmosphere and the origins of life, revealing how ancient conditions may have fostered the production of vital organic compounds.

The research, published in the *Proceedings of the National Academy of Sciences*, indicates that exposure to bright nights and dark days can significantly affect health outcomes.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Researchers found that individuals exposed to high levels of light at night faced a 21-34% increased risk of death, while those who enjoyed bright daylight saw a 17-34% reduction in their mortality risk. Senior author and sleep expert Professor Sean Cain from Flinders University emphasizes, \"Exposure to brighter nights and darker days can disrupt our circadian rhythms, which are linked to various health issues, including diabetes, obesity, cardiovascular disease, and increased mortality.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Co-senior author Associate Professor Andrew Phillips elaborates on the impact of light exposure on circadian rhythms. He notes that nighttime light can shift the timing and weaken the signals of the body’s central circadian pacemaker, which regulates various biological processes. \"Disruption of circadian rhythms is associated with the development of metabolic syndrome, diabetes, and obesity, and is also implicated in cardiometabolic diseases like myocardial infarction and stroke,\" he explains.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The study analyzed data from 89,000 UK Biobank participants aged between 40 and 69, using wrist-worn sensors to track personal light exposure over an average follow-up period of 8 years.

Their findings suggest that an organism\'s optimal pace of learning is closely linked to both the rate of environmental change and its life cycle.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">As the world constantly evolves, every organism—from microscopic bacteria to majestic blue whales—faces the challenge of adapting to shifting surroundings. Animals must learn to locate nourishing food sources that may vary with the seasons, making efficient learning crucial for survival. However, the process of learning requires both time and energy; an organism that learns too slowly risks falling behind, while one that learns too quickly may waste resources tracking insignificant changes.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The researchers\' mathematical model provides a quantitative approach to understanding the optimal learning pace. \"The key insight is that the ideal learning rate increases in a consistent manner, regardless of how quickly the environment changes or how the organism interacts with it. This suggests a universal principle applicable across diverse ecosystems,\" explains CSH PostDoc Eddie Lee.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The model envisions an environment that transitions between various states, such as wet and dry seasons, at a defined tempo. The organism perceives its surroundings and maintains a memory of past states, but older memories lose relevance over time, influenced by the organism\'s learning timescale.</p>\r\n<p class=\"reg-normal\"></p>\r\n<h2 class=\"text-1xl font-bold mb-5\">Learning at the Square Root of Change</h2>\r\n<p class=\"reg-normal\">What is the ideal learning timescale for optimizing adaptation? The model proposes a universal law: the learning timescale should be proportional to the square root of the environmental timescale. For instance, if environmental changes occur at half the speed, the organism\'s learning rate should decrease by a factor of 1.4 (the square root of 2). This relationship indicates a balance between learning too quickly and too slowly, while also suggesting diminishing returns on longer memory retention.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Additionally, the model explores organisms capable of actively shaping their environment, known as niche construction. Lee notes that if an organism can stabilize its environment, it gains an evolutionary advantage—provided it can monopolize the benefits. For example, beavers create stable habitats by building dams, securing a consistent food supply and protection from predators. However, this advantage can be undermined if other species exploit the resources of these constructed niches.</p>\r\n<p class=\"reg-normal\"></p>\r\n<h2 class=\"text-1xl font-bold mb-5\">Metabolic Overhead for Large Animals</h2>\r\n<p class=\"reg-normal\">The researchers also examined how learning abilities relate to metabolic costs—the energy requirements of an organism. They predict that for small, short-lived creatures like insects, the energy costs associated with learning and memory are significant. Conversely, for larger, longer-lived animals like mammals, the metabolic demands overshadow the costs of learning. This implies that smaller organisms exhibit finely-tuned memory adaptations, while larger animals, such as elephants, may retain information for longer but are influenced by factors beyond learning, such as social group dynamics.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The findings highlight that while small organisms have adapted to their environments with precision, larger species balance their memory retention against other survival needs. The new model provides a quantitative framework for understanding how organisms navigate the complexities of learning and survival in a dynamic world, suggesting an optimal adaptation rate that aligns with environmental change and lifespan across various life forms, from microbes to humans.</p>','2024-11-02 07:58:05.884547','uploads/news/images_6.png',1,'Complexity Science Hub','A new model from researchers at the Complexity Science Hub and Santa Fe Institute outlines how organisms should optimally learn in response to environmental changes.

The investigation analyzed survey and cognitive screening data from over 18,500 adults to explore the impact of known or suspected OSA on dementia risk.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Obstructive sleep apnea is characterized by episodes of disrupted or restricted breathing during sleep, and many individuals may be unaware that they have this condition. The findings indicate that adults aged 50 and older with known OSA or its symptoms face a higher likelihood of exhibiting signs or receiving a dementia diagnosis in the years to come. While the overall increase in dementia diagnoses was modest—never exceeding 5%—the association remained statistically significant even after accounting for other risk factors such as race and education.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The study revealed that at every age level, women with known or suspected sleep apnea were diagnosed with dementia more frequently than men. In fact, while the rate of dementia diagnoses among men decreased with age, it increased significantly for women. The results have been published in the journal *SLEEP Advances*.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">\"Our findings offer new insight into the role of a treatable sleep disorder on long-term cognitive health at the population level for both women and men,\" explained Dr. Tiffany J. Braley, the study\'s first author and a neurologist at the University of Michigan.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The reasons behind the sex-specific differences in dementia diagnosis related to sleep apnea remain unclear. However, researchers speculate that women with moderate sleep apnea may face a heightened risk of cardiovascular disease and are more susceptible to insomnia, both of which adversely affect cognitive function. \"As estrogen levels decline during menopause, women may experience memory, sleep, and mood changes that can lead to cognitive decline. Sleep apnea becomes more prevalent post-menopause but is often underdiagnosed,\" added co-author Dr. Galit Levi Dunietz.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">While approximately six million Americans have received an official diagnosis of sleep apnea, it is estimated that around 30 million may be affected by the disorder. A recent report from a Lancet Commission identified several modifiable risk factors contributing to nearly 40% of global dementia cases. Although sleep was not listed as an official risk factor, the commission acknowledged a potential association between sleep apnea and dementia, suggesting that screening questions for dementia should be considered for individuals with sleep disorders.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The study emphasizes the importance of early diagnosis and treatment of obstructive sleep apnea, as untreated cases may lead to cognitive impairment through inflammatory changes in the brain. Dr. Braley noted, \"These potential harms highlight the critical need for clinicians and patients to recognize the relationship between untreated sleep apnea and cognitive decline.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The study utilized existing data from the Health and Retirement Study, a representative survey of Americans aged 50 and older. However, the researchers caution that this observational study design cannot definitively establish causation. Co-author Dr. Ronald D. Chervin remarked, \"Proving that sleep apnea directly causes dementia would likely require a randomized trial comparing the effects of sleep apnea treatment against non-treatment over many years. In the absence of such trials, our analyses may provide valuable insights for the time being.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The findings serve as a compelling call for further exploration into how sleep disorders, particularly in women, can influence cognitive health, especially in the context of aging.</p>','2024-11-02 07:58:55.885779','uploads/news/images_35.jpeg',1,'Michigan Medicine - University of Michigan','A Michigan Medicine study highlights the association between obstructive sleep apnea and increased dementia risk in adults, particularly women.

When placed between hot and cold surfaces, the generators displayed increasing voltage correlated to the temperature difference and conductive material amount. For instance, a larger textile piece generated about 6 millivolts at a 30-degree Celsius temperature difference, suggesting potential for charging portable electronics via a USB connector when combined with a voltage converter. Remarkably, the thread maintained its performance for at least a year and proved machine washable, retaining two-thirds of its conductive properties after seven washes.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">However, the production of these thermoelectric textiles is still limited to laboratory conditions, requiring extensive manual sewing that takes several days.

The study, featured in *Couple and Family Psychology: Research and Practice*, indicates that families who increased their dinner frequency during lockdowns enjoyed more positive interactions, shared important news, and leveraged technology like videoconferencing to connect with extended family members.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Lead author Anne Fishel, PhD, a clinician and researcher in family therapy at Massachusetts General Hospital, emphasizes the need to evaluate both the frequency and quality of family meals. \"The predominance of past research on family dinners has focused on frequency as the key predictor of benefits for children and adolescents. This study highlights the importance of examining both frequency and quality to understand the full picture of how shared meals can impact families,\" Fishel noted.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The research team surveyed 517 parents from diverse ethnic and socioeconomic backgrounds in the U.S. in May 2021, exploring changes in family dinner frequency and quality during the pandemic. Participants answered questions about dinner frequency, quality, and their expectations post-pandemic, along with inquiries about their family dynamics.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Over 60% of respondents reported that they dined together more often during the pandemic compared to before. The study found a notable increase in positive interactions during these meals, including expressing gratitude, sharing laughs, and feeling a sense of connection. Specific findings revealed that:</p>\r\n<p class=\"reg-normal\">- 56% of families talked more about their daily experiences during dinner.</p>\r\n<p class=\"reg-normal\">- 60% engaged in conversations about their family identity.</p>\r\n<p class=\"reg-normal\">- 67% reported increased laughter.</p>\r\n<p class=\"reg-normal\">- 59% felt a stronger connection with one another.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">This positive trend was consistent across various demographics, including income levels, education, age, gender, and race. The pandemic also encouraged families to incorporate remote dining with extended relatives and discuss current events during meals, enhancing feelings of belonging to a larger family unit.

However, the emergence of superweeds resistant to common herbicides threatens current weed management strategies. A new study from the University of Illinois Urbana-Champaign explores how different types of farmers and fields are likely to adopt agricultural robotics for mechanical weeding and at what stage of resistance development.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Madhu Khanna, a professor of agricultural and consumer economics in the College of Agricultural, Consumer and Environmental Sciences (ACES) and director of the Institute for Sustainability, Energy and Environment at Illinois, explained, \"The exclusive reliance on herbicides for weed control has led to the appearance of superweeds, and we don\'t have anything in the pipeline in terms of new modes of action. If chemical control methods fail, it could result in millions of dollars per year in crop losses.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Small, lightweight robots designed to operate under crop canopies offer an efficient and environmentally friendly alternative. These robots use artificial intelligence for navigation and automate the process of pulling hoes through the soil to disrupt the emergence of weed seeds. Although not yet commercially available for corn and soybean crops, they hold promise for managing persistent threats like waterhemp (Amaranthus tuberculatus), which has already developed resistance to multiple herbicides.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The researchers investigated two distinct weed management strategies: myopic management, which considers immediate consequences, and forward-looking management, which anticipates future impacts. They assessed factors such as weed seed density, resistance levels, and economic thresholds that might trigger the adoption of robotic weeding at the farm level.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">According to co-author Shadi Atallah, an associate professor in ACE, \"We found that both seed density and resistance level are important for myopic management. For a forward-looking approach, seed density does not matter because resistant seeds are likely to spread in the future. This perspective considers resistance levels, but almost any level can trigger adoption.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">If a robot costs around $20,000, farmers with a forward-looking mindset are likely to adopt it when only 0.0001% of the seeds are resistant. In contrast, those with a myopic approach will wait until resistance levels exceed 5%. Atallah emphasized, \"If you\'re managing for the future, don’t even bother to look at seed density; just look at the resistance level, and no matter how low that is, you should go ahead and adopt the robots.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The study also evaluated the adoption rate and intensity over time. Findings indicated that farmers with a myopic perspective would refrain from using robots in the first six years, continuing to apply herbicides until their effectiveness waned before shifting entirely to robotic control in year seven. Conversely, forward-looking farmers would adopt robots sooner, using them to complement herbicide treatments to preserve their efficacy.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">At the outset, myopic management may lead to higher profits due to lower initial investments, but forward-looking management yields better long-term returns. Atallah pointed out, \"Farmers may adopt a myopic perspective if they lease land annually, preventing long-term planning. However, even those managing on a yearly basis will eventually need to adopt robots as other control options become ineffective.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">These differing management strategies have implications beyond individual farms, as resistant seeds can migrate to neighboring fields. A forward-looking approach can help reduce resistant seed populations, potentially reversing resistance trends. While resistance isn’t reversible for all weed species, in the case of waterhemp, the reproduction rate of resistant seeds decreases under lower selection pressure, allowing non-resistant seeds to prevail over time.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">While this research focused on maximizing profit at the farm level, future studies will explore the spillover effects of resistant seeds on neighboring farms and evaluate landscape-level impacts, providing further insights for policymakers.

Hilsabeck described the challenge of identifying relevant metabolites as finding \"needles in the haystack.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Postdoctoral fellow Vikram Narayan, PhD, then cross-referenced these findings with extensive human data from the UK Biobank.

The researchers subsequently validated their findings by reintroducing the relevant metabolites back into the flies.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The results revealed that threonine extended lifespan in a strain- and sex-specific manner, with individuals exhibiting higher levels of threonine-related metabolites enjoying longer and healthier lives. Kapahi cautioned, however, that threonine may not be universally effective, stating, \"We\'re not saying that threonine is going to work in all conditions. Our research shows it works in subsets of both flies and people.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Interestingly, the study also identified metabolites with negative associations with aging. Orotate, a lesser-known metabolite linked to fat metabolism, counteracted the benefits of dietary restriction in fruit flies and was associated with shorter lifespans in humans. Kapahi emphasized the larger implications of their findings, urging the scientific community to adopt this method to enhance the translational relevance of research. \"This approach allows us to say with a lot more certainty that discoveries are going to be relevant in humans,\" he stated, expressing hope that it could reduce reliance on mouse studies in future research.</p>','2024-11-02 08:02:58.386418','uploads/news/images_33.jpeg',1,'Buck Institute for Research on Aging','Researchers at the Buck Institute have developed a machine learning approach that links metabolites in fruit flies to human health, identifying threonine as a potential therapeutic for aging interventions.',1,36,'<ul>\r\n                <li>Justin R.

Barrett\'s esophagus occurs when the esophageal lining is damaged due to prolonged exposure to stomach acid, with lifestyle choices like drinking and smoking contributing to its development. Current estimates suggest that 2-4% of Australians have Barrett\'s esophagus, primarily affecting men over 40 years old, many of whom remain unaware of their condition due to symptoms that mimic regular heartburn.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Dr. Norma Bulamu from the College of Medicine and Public Health, the lead author of the study, emphasizes the urgency of this research: \"In most industrialized countries, including Australia, the incidence of esophageal cancers has increased fivefold in the past 40 years, with almost all these cancers arising from underlying Barrett\'s esophagus. This condition is clinically significant because individuals with Barrett\'s esophagus are at a heightened risk of developing esophageal cancer, which has a dismal five-year survival rate of about 20 percent. Our research aims to uncover better ways to identify and treat Barrett\'s esophagus to mitigate its progression to esophageal cancer and enhance patient survival rates.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Currently, diagnosis typically involves an endoscopy, an invasive procedure that examines the esophagus lining. The findings, published in the *Journal of Gastroenterology and Hepatology*, propose a multi-step strategy for Barrett\'s esophagus identification in the community. This approach starts with assessing patient risk levels, followed by the use of less invasive devices, and concludes with endoscopy only when necessary.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">One promising device under consideration is a non-endoscopic, pill-sized instrument that collects esophageal cells, which can then be retrieved via a string for testing. However, such devices are not yet available in Australia. Dr. Bulamu notes, \"Currently, there is no routine screening for Barrett\'s esophagus. Identification is opportunistic, limited to endoscopy, which is invasive for patients and costly for the healthcare system. Implementing a multi-step strategy is generally more economical than immediately resorting to endoscopy. The integration of less-invasive non-endoscopic devices with risk assessments could lead to an effective and cost-efficient screening method.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Senior researcher Professor David Watson adds that the study also evaluated blood-based screening tools, which were found to increase costs without significantly enhancing diagnostic accuracy. For blood tests to be viable, they need to demonstrate significantly higher sensitivity and specificity or be offered at a lower price point. Professor Watson states, \"If our approach can be successfully implemented in clinics, it could facilitate screening, enabling the identification of patients with Barrett\'s esophagus for regular surveillance. This would allow for earlier diagnosis and treatment, particularly for those at increased risk of esophageal cancer.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">While the research shows promise, the team acknowledges some limitations and suggests that further studies are needed to assess quality of life benefits and survival rates associated with early identification of esophageal cancer.

This widely recognized thought experiment serves to illustrate concepts of probability and randomness, demonstrating how chance can lead to unexpected outcomes.

For their calculations, the researchers assumed a keyboard with 30 keys, encompassing all letters of the English language and common punctuation. They analyzed scenarios with a single monkey as well as the current global population of approximately 200,000 chimpanzees, with the assumption of a typing speed of one key every second until the estimated end of the universe in about 10^100 years—a staggering figure represented by a 1 followed by 100 zeros.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The findings indicate that while a single chimp has a roughly 5% chance of typing the word \'bananas\' in its lifetime, even the combined efforts of all chimps would not suffice to produce Shakespeare\'s complete works (approximately 884,647 words) before the universe concludes.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The authors note, \"It is not plausible that, even with improved typing speeds or a larger chimpanzee population, monkey labor will ever serve as a practical method for generating significant written works.\" This study situates the theorem alongside other probability puzzles and paradoxes—such as the St. Petersburg paradox, Zeno\'s paradox, and the Ross-Littlewood paradox—where the concept of infinite resources yields outcomes that diverge from our understanding under finite constraints.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">In the age of generative AI, both the Infinite Monkey Theorem and its finite counterpart prompt philosophical considerations about the nature of creativity, meaning, and consciousness, and how these attributes emerge.</p>','2024-11-02 08:06:08.365440','uploads/news/images_31.jpeg',1,'University of Technology Sydney','A new study challenges the Infinite Monkey Theorem by examining the likelihood of producing Shakespeare\'s works under finite constraints, revealing that even with a global population of chimpanzees, it remains implausible to type out significant literary works before the universe ends.',1,62,'<ul>\r\n                <li>Stephen Woodcock, Jay Falletta.

In a review published in *Trends in Ecology &amp; Evolution*, researchers argue that ethanol, which is naturally present in nearly every ecosystem, is likely consumed regularly by most fruit- and nectar-eating animals.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Behavioral ecologist and senior author Kimberley Hockings from the University of Exeter explains, \"We\'re moving away from this anthropocentric view that ethanol is just something that humans use. It\'s much more abundant in the natural world than we previously thought, and most animals that eat sugary fruits are going to be exposed to some level of ethanol.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Ethanol became prevalent around 100 million years ago, coinciding with the emergence of flowering plants that produce sugary nectar and fruits amenable to fermentation by yeasts. Although ethanol is present in various ecosystems, its concentration is typically higher and more consistent in lower-latitude, humid tropical environments than in temperate regions. Natural fermentation of fruits often results in alcohol content of only 1%-2% ABV, but concentrations as high as 10.2% ABV have been recorded in overripe palm fruit in Panama.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Interestingly, animals already possessed genes capable of degrading ethanol before yeasts began producing it, and there is evidence of evolutionary adaptation among mammals and birds that consume fruit and nectar, particularly in primates and treeshrews, who metabolize ethanol efficiently.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">From an ecological standpoint, becoming inebriated poses risks for animals that climb trees or face predators, which stands in contrast to humans who often seek intoxication without the caloric intake. Molecular ecologist Matthew Carrigan of the College of Central Florida notes, \"It\'s the opposite of humans who want to get intoxicated but don\'t really want the calories—non-human animals want the calories but not the inebriation.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The research raises questions about whether animals intentionally seek ethanol, as further investigation is needed to determine its effects on animal physiology and evolution. Nonetheless, the team posits several potential benefits of ethanol consumption for wildlife.

Published in *Scientific Reports*, the research indicates that these tiny plastic particles not only hinder the effectiveness of antibiotic treatments but may also encourage the emergence of antibiotic-resistant bacteria.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Led by Lukas Kenner from MedUni Vienna, along with Barbara Kirchner from the University of Bonn and Oldamur Hollóczki from the University of Debrecen, the team focused on the interactions between a common antibiotic, tetracycline, and various types of nanoplastics. Tetracycline is a broad-spectrum antibiotic frequently used to treat bacterial infections, including respiratory, skin, and intestinal infections. The plastics studied include polyethylene (PE), polypropylene (PP), polystyrene (PS)—all common in packaging—and nylon 6,6 (N66), prevalent in textiles like clothing and carpets.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Nanoplastics, defined as particles smaller than 0.001 millimeters, pose a significant risk to both human health and the environment due to their diminutive size. Utilizing complex computer models, the researchers demonstrated that these nanoplastic particles can bind to tetracycline, thereby impairing its effectiveness. Kenner noted, \"The binding was particularly strong with nylon,\" highlighting a significant yet underestimated indoor risk: \"Micro- and nanoplastic loads are around five times higher indoors than outdoors, primarily due to nylon being released from textiles and entering the body through respiration.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">A critical concern raised by the study is the potential for antibiotic resistance. The research found that the binding of tetracycline to nanoplastics could diminish the antibiotic\'s biological activity while also leading to the drug being transported to unintended areas within the body. This misdirection could diminish its targeted effects and introduce undesirable outcomes. Kenner pointed out a particularly troubling detail: \"The local concentration of antibiotics on the surface of the nanoplastic particles can increase, which raises the risk of developing antibiotic-resistant bacteria.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The findings suggest that plastics like nylon 6,6 and polystyrene, which exhibit stronger binding to tetracycline, could elevate the risk of antibiotic resistance. Kenner emphasized the growing global threat of antibiotic resistance, stating, \"At a time when antibiotic resistance is becoming an ever-greater threat worldwide, such interactions must be taken into account.\" The study underscores that exposure to nanoplastics presents a dual risk: a direct threat to health and an indirect influence on the effectiveness of disease treatments.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Kenner concluded with a note of caution regarding future research: \"If nanoplastics reduce the effectiveness of antibiotics, determining appropriate dosages poses a significant challenge,\" urging further investigation into the impact of nanoplastics on other medications.</p>','2024-11-02 08:07:31.554533','uploads/news/images_29.jpeg',1,'Medical University of Vienna','An international study highlights the detrimental effects of nanoplastic particles on antibiotics, showing that they can impair drug efficacy and promote antibiotic resistance, raising significant health concerns.',1,4,'<ul>\r\n                <li>Leonard Dick, Patrick R.

The research reveals that sustainable lifestyles, green-tech innovations, and government-led transformations can significantly advance progress in these areas. Contrary to the perception that sustainable development is increasingly unattainable, the findings suggest that humanity has multiple strategies to shift away from its current unsustainable trajectory.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Bjoern Soergel, a scientist at PIK and the lead author of the study published in *Environmental Research Letters*, explains, \"Sustainable development pathways are strategies that prevent dangerous climate change while at the same time moving towards a world that allows people to prosper on a healthy planet.\" These pathways align with the 17 SDGs established by the United Nations in 2015.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The analysis indicates that all three sustainable development pathways outperform the current \'business as usual\' approach. They could reduce the number of individuals living in extreme poverty by two-thirds by 2030 and bring that number to virtually zero by 2050. Additionally, these pathways would mitigate global warming and prevent further environmental degradation. Importantly, they avoid the unintended consequences of simplistic climate protection strategies that overly rely on bioenergy or carbon capture without considering conflicts with food production or public acceptance.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The study examines three distinct pathways toward the SDGs, utilized by governments, companies, and NGOs to promote a sustainable future. This research is notable for being the first to systematically compare such diverse pathways, analyzing data from four models: two integrated assessment models addressing the global energy, economy, land, and climate systems, and two models focused on global buildings and materials sectors.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Isabelle Weindl, a PIK scientist and co-author of the study, highlights the importance of the question, \"All scenarios we looked into share the same set of goals, but the question is how to get there.\" Each pathway examined presents unique advantages. For instance, the sustainable lifestyle pathway emphasizes a swift transition to a flexitarian, primarily plant-based diet, which also offers significant health benefits. This approach aims for a reduction of global final energy use per capita of approximately 40% by 2050, with wealthier nations taking the lead in decreasing energy inequality. While these changes may present challenges regarding public adoption, they promise substantial benefits, as Soergel points out: \"The sustainable lifestyle pathway has the lowest reliance on unproven technologies and the most positive outcomes for biodiversity and climate protection.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">In contrast, the other pathways propose a gradual shift in diets and energy use while advocating for faster innovations in green technologies and enhanced government interventions. Each pathway comes with its own set of challenges. Elmar Kriegler, head of the research department Transformation Pathways at PIK and co-author of the study, emphasizes that, despite the differences in emphasis, all pathways can achieve their goals. \"If we stick to our current trajectory, none of the SDGs will be achieved. By 2030, 660 million people could still be living in extreme poverty, and environmental crises like biodiversity loss and global warming will worsen. It is clear we must act now. We can still choose which sustainable path to pursue, but ignoring them is no longer an option.\"</p>','2024-11-02 08:08:12.253353','uploads/news/SDG-illo-hires-c30a1488245caf97b1da2d1cce5a3d6d.jpg',1,'Potsdam Institute for Climate Impact Research (PIK)','A study from the Potsdam Institute for Climate Impact Research reveals three viable pathways to achieving the UN Sustainable Development Goals and addressing climate change, highlighting the importance of sustainable lifestyles, green technology, and government action.',1,231,'<ul>\r\n                <li>Bjoern Soergel, Sebastian Rauner, Vassilis Daioglou, Isabelle Weindl, Alessio Mastrucci, Fabio Carrer, Jarmo Kikstra, Geanderson Ambrósio, Ana Paula Dutra Aguiar, Lavinia Baumstark, Benjamin Leon Bodirsky, Astrid Bos, Jan Philipp Dietrich, Alois Dirnaichner, Jonathan C Doelman, Robin Hasse, Ariel Hernandez, Johanna Hoppe, Florian Humpenöder, Gabriela Ileana Iacobuţă, Dorothee Keppler, Johannes Koch, Gunnar Luderer, Hermann Lotze-Campen, Michaja Pehl, Miguel Poblete-Cazenave, Alexander Popp, Merle Remy, Willem-Jan van Zeist, Sarah Cornell, Ines Dombrowsky, Edgar G Hertwich, Falk Schmidt, Bas van Ruijven, Detlef van Vuuren, Elmar Kriegler.

This innovation relies on hypersensitive receivers and noise-free amplifiers to ensure that signals can travel vast distances without interference.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Unlike traditional radio wave communication, space communication increasingly depends on optical laser beams, which have been shown to incur less signal loss over long distances. However, even optical signals weaken during their journey, necessitating the use of extremely sensitive receivers capable of detecting faint signals upon their arrival on Earth.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The team at Chalmers has introduced a communication system that features an optical amplifier designed to enhance the signal while minimizing noise, allowing for effective data recycling. According to Peter Andrekson, Professor of Photonics at Chalmers and a lead author of the study published in *Optica*, \"We can demonstrate a new system for optical communication with a receiver that is more sensitive than has been demonstrated previously at high data rates. This means that you can get a faster and more error-free transfer of information over very long distances, for example, when you want to send high-resolution images or videos from the Moon or Mars to Earth.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The key innovation lies in the system\'s silent amplifier, which amplifies the signal with minimal noise. Traditionally, signals from space become so weak that they can be obscured by electronic noise within the receiver. After two decades of grappling with this challenge, the Chalmers team successfully demonstrated a noise-free optical amplifier. However, the amplifier\'s complexity previously hindered its practical application in optical communication systems due to the stringent demands placed on transmitters and receivers.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">To address this, the researchers devised a method in which the Earth-based receiver generates two of the three necessary light frequencies for noise-free amplification, while the transmitter only needs to produce one frequency. This innovation allows the noise-free amplifier to be integrated into an optical communication system for the first time, resulting in remarkable sensitivity without increasing the transmitter\'s complexity. Rasmus Larsson, a Postdoctoral Researcher in Photonics at Chalmers and co-author of the study, explains, \"This phase-sensitive optical amplifier does not, in principle, generate any extra noise, which contributes to a more sensitive receiver and that error-free data transmission is achieved even when the power of the signal is lower.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The advancement promises to solve a critical bottleneck faced by space agencies, often referred to as \'the science return bottleneck.\' NASA highlights this issue, emphasizing that the speed of data collection from space to Earth can hinder scientific progress. Andrekson asserts, \"We believe that our system is an important step forward towards a practical solution that can resolve this bottleneck.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The next phase of research involves field testing the optical communication system with the new amplifier on Earth, followed by trials in communication links between satellites and Earth.

A recent study published in *Environmental Science &amp; Technology Letters* by researchers at the University of Southern California has uncovered concerning findings about these fire suppressants. They discovered that several of these products contain elevated levels of toxic metals, including chromium and cadmium, which could contribute to increased metal concentrations in waterways after wildfires are extinguished.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">\"Wildfires are associated with the release of toxic heavy metals to the environment, but until now, it was assumed that these metals came from natural sources like soil,\" explains Daniel McCurry, the principal investigator of the study. This revelation suggests that fire retardants themselves may be a source of these harmful metals.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Fire suppression products, which are designed to inhibit fire activity before and after water evaporates, include fire retardants, water enhancers, and foams. With wildfires becoming increasingly frequent and severe, there is a growing need for larger volumes of water and these chemical suppressants, which are sprayed from both the ground and aircraft to combat the flames.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">While manufacturers typically disclose most active ingredients in these suppressants, some components remain proprietary. Previous studies have documented increased concentrations of potentially toxic metals in soil and streams following wildfires, prompting McCurry and his team to investigate the possible contamination from suppressants.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The researchers analyzed samples from 14 commercially available fire suppression products, testing for 10 metals known for their toxicity or regulated by the U.S. Environmental Protection Agency (EPA). Alarmingly, every product contained at least one metal at concentrations exceeding the EPA\'s Maximum Contaminant Level regulations for drinking water. Notably, two products classified as fire retardants were found to contain eight metals—chromium, cadmium, arsenic, lead, vanadium, manganese, antimony, and thallium—well above the EPA\'s safe limits. One of the retardants even exceeded California\'s hazardous waste regulations for three of these metals.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">These findings highlight the potential for fire retardants to contaminate aquatic environments and drinking water sources if they enter nearby bodies of water. An analysis of the volume of fire retardants used in the U.S. from 2009 to 2021 indicated a variable but generally increasing trend in the total amount of metals applied. For one wildfire in Southern California, researchers estimated that 31% of the observed cadmium concentration in a nearby stream could be attributed to the fire retardant used during the incident.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">While these results demonstrate that fire suppression activities could elevate metal levels in the environment, the researchers stress that further investigation is necessary to assess the potential risks to human and environmental health.

In a study published in the October 30 online issue of *Cell*, the team identified how these tumors manipulate their environment to resist treatment and pinpointed a potential drug target that could help overcome this resistance.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The research employed advanced spatial genomics technology alongside preclinical animal models and tumor specimens from ovarian cancer patients to validate their findings. A significant discovery was that ovarian cancer cells produce a molecule called Interleukin-4 (IL-4), which is commonly associated with conditions like asthma and eczema. This molecule helps create a protective environment that shields the tumors from killer immune cells, rendering them resistant to immunotherapy.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">A drug named dupilumab, which blocks IL-4\'s activity, has already received FDA approval for treating asthma and eczema. The findings from this study suggest that dupilumab, or similar drugs, could be repurposed to enhance the effectiveness of immunotherapy for ovarian cancer—a disease that has a high mortality rate, with 50 percent of patients dying within five years of diagnosis.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Current immunotherapy options, such as pembrolizumab that targets the PD-1 molecule, have shown effectiveness in treating other cancers like melanoma and lung cancer but have not significantly improved survival rates for ovarian cancer. One reason for this ineffectiveness is that ovarian tumors typically have fewer mutations, making it more difficult for the immune system to recognize them. Moreover, these tumors often develop barriers that prevent immune cells from infiltrating their borders.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">To investigate how tumors establish these protective environments, the research team, led by Dr. Alessia Baccarini and Dr. Brian D. Brown, utilized a novel genomics technology called Perturb-map. This technique enhances traditional CRISPR screening by integrating spatial imaging, allowing for a better understanding of each gene\'s role in shaping the tumor environment. Their experiments revealed that removing the IL-4 gene from ovarian cancer cells made the tumors susceptible to anti-PD-1 therapy. Remarkably, even when mixed with IL-4-producing cancer cells, the IL-4-deficient cancer cells were eliminated by the immune system, showcasing the concept of intratumoral heterogeneity, which often contributes to drug resistance.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The team further tested a combination of anti-PD-1 therapy and IL-4 receptor-blocking drugs in mice with aggressive metastatic ovarian cancer, resulting in significantly extended survival rates. Additional studies demonstrated that ovarian cancer employs IL-4 to program macrophages, a type of immune cell, into protectors of the cancer cells. These IL-4-programmed macrophages inhibit T cells from effectively targeting the cancer cells. However, blocking IL-4 altered the local environment around the cancer cells, making them vulnerable to immune elimination.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">To validate their findings, the researchers analyzed tumor samples from ovarian cancer patients and confirmed that the cancer cells also produced IL-4. Additionally, single-cell RNA sequencing revealed that the macrophages in these tumors displayed a strong IL-4 signature, indicating that IL-4 plays a similar role in human ovarian cancer and may contribute to the lack of benefits from immunotherapy for patients.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Dr. Brown remarked on the significance of these findings, noting that ovarian cancer had been largely considered non-responsive to existing immunotherapies. He emphasized the potential impact of simply blocking IL-4 to alter the tumor microenvironment, making these difficult-to-treat tumors more manageable. While these results are promising, the researchers stress the need for clinical trials to assess whether targeting IL-4 can enhance patient outcomes.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Given dupilumab’s existing FDA approval for asthma and eczema, there is potential for rapid clinical testing alongside immunotherapy to improve survival rates for ovarian cancer patients. Dr. Thomas Marron, Director of the Early Phase Trial Unit at Mount Sinai, is already exploring whether dupilumab can enhance anti-PD-1 immunotherapy in lung cancer patients, with several showing positive responses. Dr. Baccarini expressed optimism, stating, \"Ovarian cancer is a disease that\'s so hard to catch early and once diagnosed, it\'s often too late. I am excited that these findings may make a difference in patients\' lives. The IL-4 pathway is already targeted for diseases like eczema, and I am hopeful that if we target it in ovarian cancer, we can help women facing this terrible disease.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The research received support from various NIH awards and foundations, underscoring the importance of this study in advancing treatment options for ovarian cancer.</p>','2024-11-02 08:14:31.148644','uploads/news/images_24.jpeg',1,'The Mount Sinai Hospital / Mount Sinai School of Medicine','Mount Sinai researchers have identified how ovarian cancer tumors manipulate their environment to resist immunotherapy and discovered that blocking the molecule IL-4 could enhance treatment effectiveness.

This significant research was published today in *JAMA Psychiatry* under the title \"Slowing cognitive decline in major depressive disorder and mild cognitive impairment: A randomized controlled trial.\" The study reports the primary findings of the PACt-MD (Prevention of Alzheimer\'s dementia with Cognitive remediation plus transcranial direct current stimulation in Mild cognitive impairment and Depression) project, which received funding from the Canada Brain Research Fund.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The PACt-MD study focused on preventing cognitive decline in older adults suffering from conditions that heighten the risk for dementia, specifically Major Depressive Disorder in remission (rMDD), Mild Cognitive Impairment (MCI), or both. The Honourable Mark Holland, Minister of Health, emphasized the importance of this long-term research, stating, \"Investing in long-term, comprehensive research like this is not only a commitment to science but to the millions of individuals, families, and caregivers affected by dementia.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">In total, 375 older adults participated in the study, receiving either a control (“sham”) intervention or a combination of two active therapies. The first therapy involved specially designed Cognitive Remediation (CR) techniques aimed at improving cognitive functioning through activities like puzzles and logic problems. The second therapy was transcranial direct current stimulation (tDCS), a form of non-invasive brain stimulation. These therapies were administered five days a week for eight weeks, with follow-up “boosters” every six months.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The study was designed as a randomized, controlled, and double-masked trial, with assessments conducted at baseline, two months, and annually for a period of three to seven years. Results revealed that participants who received the combination of CR and tDCS experienced a slower rate of cognitive decline over a median follow-up period of four years compared to those who received the control intervention. Notably, the benefits were more pronounced in individuals with a lower genetic risk for Alzheimer\'s disease. Moreover, participants with rMDD (with or without MCI) showed better cognitive outcomes than those with MCI alone.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The overlapping nature of conditions contributing to cognitive decline underscores the importance of combination therapies, which can target different disease pathways synergistically to enhance patient outcomes. Dr. Tarek Rajji, lead author and Principal Investigator of the study, expressed satisfaction with the results, stating, \"We are very pleased to show, after seven years of close monitoring, that this combination of therapies is effective in slowing down cognitive decline for some of our most vulnerable populations.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Dr. Benoit Mulsant, senior author and lead of the research team, elaborated on the study\'s focus on the prefrontal cortex, an area of the brain essential for executive functioning and believed to be highly adaptable. He noted, \"While there are several presumed mechanisms underlying the increased risk for dementia in older adults with depression, impaired brain plasticity is thought to be one common pathway. In this study, we targeted the prefrontal cortex for treatment.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">As this promising research moves forward, it highlights the potential for non-pharmacological approaches to support individuals at high risk for dementia, helping them maintain independence for longer periods.

Published in *JAMA Surgery*, the study indicates that individuals aged 67 and older may experience double or even triple the risk of life-threatening complications, such as a debilitating stroke or another heart attack, if they proceed with surgery too quickly following a non-ST-segment elevation myocardial infarction (NSTEMI).</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The research analyzed data from the Medicare database, covering 5.2 million surgeries performed between 2017 and 2020. The findings suggest that waiting three to six months after an NSTEMI before scheduling additional surgical procedures can significantly lower the associated risks. This study aims to identify the optimal timing, or the \"sweet spot,\" for safely conducting surgeries in this vulnerable population, offering insights to potentially update decision-making guidelines that have remained unchanged for over two decades.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Dr. Laurent Glance, the lead author and a professor of Anesthesiology and Perioperative Medicine and Public Health Sciences at the University of Rochester Medical Center (URMC), emphasized the importance of current data for patient care decisions: \"The data physicians are using for patient care decisions today is outdated. Given the advances in care and the ever-changing mix of patients, clinicians need the latest information.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The existing American College of Cardiology and American Heart Association guidelines recommend waiting 60 days after a heart attack before undergoing elective noncardiac surgery. These guidelines were based on an analysis of 500,000 patients between 1999 and 2004. However, this new analysis reveals a decline in risk during the first 90 days following a heart attack, after which the risk levels off for the next 180 days.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">For aging patients who often present with multiple acute or chronic conditions, physicians face the challenge of balancing the risks of surgical procedures with patients\' expectations for quality of life. Dr. Marjorie Gloff, a co-author and director of URMC\'s Center for Perioperative Medicine, noted the difficulties that arise: \"Perioperative teams analyze a variety of health and lifestyle factors when we assess a patient\'s risk and work to optimize their outcomes.

Previously, researchers believed that the combination of chloroplasts—structures in plants and algae that contain chlorophyll—with animal cells was not feasible, as it was thought that chloroplasts would either not survive or would not function properly within the animal cells. However, the results demonstrated that photosynthetic activity persisted for at least two days after integration.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">This innovative technique holds promise for advancements in artificial tissue engineering. One of the challenges faced in tissue growth is oxygen deprivation, which can hinder development. By incorporating chloroplast-infused cells, it may be possible to supply energy and oxygen through light exposure and photosynthesis.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Imagine a world where you could harness the power of the sun to fuel your energy needs, akin to how plants and algae do. While this may sound like something out of science fiction, some animals, like giant clams, have already established symbiotic relationships with algae. In this arrangement, the algae, equipped with chloroplasts, photosynthesize to produce food and oxygen, while the clams provide shelter for the algae.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Professor Sachihiro Matsunaga from the University of Tokyo, the corresponding author of the research paper, stated, \"As far as we know, this is the first reported detection of photosynthetic electron transport in chloroplasts implanted in animal cells.\" Photosynthetic electron transport is vital for generating chemical energy, which supports numerous cellular functions in plants and algae. Professor Matsunaga added, \"We initially thought that the chloroplasts would be digested by the animal cells within hours, but our findings showed they continued to function for up to two days, demonstrating active electron transport and photosynthesis.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">In their experiments, the researchers inserted chloroplasts from red algae into cultured hamster cells. They utilized various imaging techniques, including confocal microscopy, superresolution microscopy, and electron microscopy, to examine the structure of the chloroplasts within the cells. Additionally, they confirmed photosynthetic electron transport through pulses of light using a technique known as pulse amplitude modulation fluorometry.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Matsunaga noted, \"This work has significant implications for cellular tissue engineering.

Their findings, published on October 30 in the American Journal of Psychiatry, reveal new clusters of cells with distinct gene expression patterns in the amygdala of both humans and non-human primates. This research holds promise for developing targeted treatments for anxiety and depression, disorders that affect millions worldwide.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Drew Fox, associate professor in the UC Davis Department of Psychology and senior author of the study, emphasized the importance of the amygdala in emotional processing. While variations in the size or structure of the amygdala have been linked to anxiety and depression, Fox notes that these factors do not reliably predict emotional issues. Recent research in rodents suggests that specific subregions of the amygdala contain various cell types with distinct and sometimes opposing functions, indicating that disorders may arise from alterations in these specific cell types.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">To bridge the knowledge gap regarding cell types in the primate amygdala, graduate student Shawn Kamboj spearheaded a collaboration between Fox’s team and Professor Cynthia Schumann’s lab at the UC Davis School of Medicine. They utilized single-cell RNA sequencing to analyze samples from human and rhesus macaque brains, identifying and categorizing cell types based on their gene expression. This innovative approach allows researchers to better relate findings across species and potentially identify new treatment targets.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">One key finding was the identification of cells expressing the gene FOXP2 in both humans and macaques. These cells, located on the edges of the amygdala, are known as intercalated cells, which have been shown to act as \"gatekeepers\" for signal traffic in the amygdala in rodents. This discovery suggests that intercalated cells could be a vital avenue for developing treatments for anxiety and related disorders.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The study also highlighted both similarities and differences in cell types between humans and non-human primates, enhancing understanding of how animal models relate to human psychopathology. For instance, the FOXP2-expressing cells also showed expression of the Neuropeptide FF Receptor 2 (NPFFR2), a receptor that could be targeted by pharmacological treatments. This insight could guide the development of new therapeutic strategies that activate the NPFFR2 pathway to address anxiety-related disorders.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Anxiety manifests in various ways, and a deeper understanding of the involved cell types could help identify \"chokepoints\" that affect a large number of individuals suffering from extreme anxiety.

This regrowth could sequester an impressive 23.4 gigatons of carbon over 30 years, addressing critical issues such as biodiversity loss and water quality.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The study, which highlights the importance of natural regeneration, indicates that more than half of the identified areas suitable for regrowth are located in five key countries: Brazil, Mexico, Indonesia, China, and Colombia. Co-lead author Brooke Williams, a researcher at the Queensland University of Technology and the Institute for Capacity Exchange in Environmental Decisions, emphasized that leveraging natural regeneration techniques can provide a cost-effective alternative to tree planting in degraded landscapes, helping nations achieve their restoration goals.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The study\'s foundation was laid by Matthew Fagan, an associate professor at the University of Maryland, Baltimore County (UMBC), who developed a dataset used in this research. By utilizing satellite imagery, Fagan identified millions of small areas with increased tree cover from 2000 to 2012, excluding areas that were artificially planted. This approach allowed the team to focus on natural regrowth, making this study the first of its kind to predict future forest regrowth based on observed past changes.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The study was co-led by Hawthorne Beyer, head of geospatial science at Mombak, a Brazilian startup focused on generating high-quality carbon credits through Amazon reforestation. The research drew on extensive global datasets, considering factors such as soil quality, slope, population density, and proximity to existing forests.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The findings revealed that the strongest predictors of regrowth potential include a patch\'s proximity to existing forest, the density of nearby forest, and soil carbon content. These factors help explain the patterns of regrowth observed worldwide, as close proximity to existing forests facilitates the availability of diverse seeds crucial for successful regeneration.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The culmination of this research is a comprehensive digital map of the global tropics, where each pixel (representing 30 x 30 square meters) indicates the estimated potential for regrowth.

These T cells rely on tiny protein fragments displayed by presenting immune cells to recognize and respond to danger. The researchers found that guardian peptides were prominently presented by immune cells at the brain\'s borders, effectively attracting and activating regulatory T cells that help suppress abnormal immune reactions.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Min Woo Kim, a graduate student in the Medical Scientist Training Program at WashU Medicine, investigated the immune cells in healthy mice and discovered a wealth of brain proteins presented by these cells, particularly a component of the myelin sheath. This protective covering of neurons is often damaged in conditions like multiple sclerosis (MS). The study noted a significant depletion of these proteins in mice with MS. By injecting missing brain-derived peptides into the cerebrospinal fluid of MS-affected mice, the scientists were able to activate and expand suppressor T cells, leading to improved motor function and slowed disease progression compared to control groups.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Kim stated, \"We have identified a novel process in the brain where the organ actively engages with the immune system to present a healthy image of itself.

This research marks the first time an international team of scientists has been able to quantify meltwater using positioning data, challenging existing models of how ice sheets contribute to global sea level rise. Currently, the Greenland Ice Sheet is the largest single contributor to global sea-level rise, with the potential to raise mean sea levels by as much as seven meters if it were to completely melt.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Despite extensive studies on the melt processes of the ice sheet, a key question remained: how does the storage of meltwater evolve within the ice sheet throughout the summer melt season? The study introduces a novel approach that provides an unprecedented view of meltwater movement and storage. Jiangjun Ran, an associate professor at Southern University of Science and Technology, explains, \"During the melt season, we found that a significant fraction of meltwater mass is stored temporarily within the ice sheet. This water buffering effect peaks in July and slowly recedes in the following weeks.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Utilizing data from the Greenland GPS Network (GNET), which consists of numerous stations around Greenland that continuously provide positioning data, the research team developed an innovative method to interpret the vertical displacements of the bedrock. These displacements occur as the mass of melting water pushes the bedrock down, allowing for a clearer understanding of how water is stored and released within the ice sheet.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The implications of this discovery are substantial for climate models, which often underestimate the complexity of water storage in ice sheets. During warmer years, models predicting water runoff toward the ocean may easily overlook this process, potentially requiring scaling adjustments of up to 20% for the warmest years. Michiel van den Broeke, a professor at Utrecht University, emphasizes, \"These findings are crucial for improving forecasts of the Greenland Ice Sheet\'s contribution to future sea-level rise. With climate change making the Arctic warmer than ever, accurate predictions are essential for preparing coastal regions for potential sea-level rise.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The study is the culmination of years of preparation and challenging expeditions to some of the most remote locations on Earth.

Aurochs roamed across Europe, Asia, and Africa for hundreds of thousands of years, and their domestication has led to the development of cattle, which now represent a third of the world\'s mammalian biomass.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Dr. Conor Rossi from Trinity, the first author of a recently published article in *Nature Communications*, stated, \"The aurochs went extinct approximately 400 years ago, which left much of their evolutionary history a mystery. However, through the sequencing of ancient DNA, we have gained detailed insights into the diversity that once thrived in the wild, as well as a better understanding of domestic cattle.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Although fossil records indicate that aurochs existed in Europe for up to 650,000 years, the researchers found that animals from the eastern and western extremes of Eurasia share a more recent common ancestry, suggesting a replacement around 100,000 years ago likely due to migrations from a southern Asian homeland. This replacement was not entirely complete, as traces of earlier ancestry survived in European aurochs.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Dr. Mikkel Sinding, co-author and postdoctoral researcher at the University of Copenhagen, noted, \"We typically view the European aurochs as one common type, but our analyses indicate there were three distinct populations: Western European, Italian, and Balkan. This suggests a much greater diversity in wild forms than we previously imagined.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Climate change has also left its mark on aurochs genomes in two significant ways: Firstly, European and north Asian genomes diverged at the onset of the last ice age, around 100,000 years ago, showing little mixing until the climate warmed again. Secondly, the study revealed that population sizes of aurochs dropped during the glacial period, with European herds experiencing the most pronounced declines as they retreated to isolated refugia in southern regions of the continent before repopulating afterward.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The most significant reduction in genetic diversity occurred between the domestication of the southwest Asian aurochs, just over 10,000 years ago, and the emergence of the first cattle. Remarkably, only a few maternal lineages, traced through mitochondrial DNA passed from mothers to offspring, contributed to the cattle gene pool. Dr. Dan Bradley, Professor at Trinity\'s School of Genetics and Microbiology and lead researcher of the study, commented, \"While Caesar exaggerated when he compared it to an elephant, the wild ox must have been a dangerous beast, suggesting that its initial capture and taming involved only a handful of animals.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">He further explained, \"The narrow genetic base of the first cattle was expanded as they spread with their herders, leading to extensive mating with wild aurochs bulls. This left a legacy of the four separate pre-glacial aurochs ancestries that continues among today\'s domestic cattle.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">This research not only sheds light on the history of aurochs but also underscores the intricate connections between climate change, genetic diversity, and the domestication processes that shaped one of humanity\'s essential livestock species.</p>','2024-11-02 08:25:22.668618','uploads/news/images_17.jpeg',1,'Trinity College Dublin','An international study decodes the prehistory of aurochs through genomic analysis, revealing their evolutionary history and the impact of climate change on their genetic diversity.

Researchers from the Wellcome Sanger Institute, in collaboration with the University of Zurich, mapped the behavior of stem cells in recipients\' bodies up to three decades post-transplant. This groundbreaking study, published on October 30 in *Nature* and partially funded by Cancer Research UK, reveals that stem cell transplants from older donors often yield significantly fewer surviving vital stem cells — ten times fewer, in fact — compared to transplants from younger donors.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The findings are crucial, especially since over a million people are diagnosed with blood cancer globally each year, including leukemia and lymphoma. Stem cell transplants, also known as bone marrow transplants, frequently represent the only curative option for patients. These procedures involve replacing damaged blood cells with healthy stem cells from a donor, thereby rebuilding the patient’s blood and immune system. In the UK, more than 2,000 people undergo this procedure annually. Despite being performed for over five decades, many fundamental questions about the inner workings of transplants have remained unanswered, particularly regarding the role donor age plays in transplant success.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Using advanced genome sequencing techniques, the researchers analyzed blood samples from ten donor-recipient sibling pairs, tracking changes over up to 31 years post-transplant. By examining mutations in the donor and recipient’s stem cells, they could determine how many cells survived the transplant process and continued producing new blood cells. The study found that transplants from younger donors in their 20s and 30s typically result in around 30,000 long-term surviving stem cells, compared to only 1,000 to 3,000 in older donors. This significant reduction could explain the poorer outcomes often associated with older donors, leading to reduced immunity and higher relapse risks.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Additionally, the transplant process appeared to age recipients’ blood systems by approximately 10 to 15 years compared to matched donors, primarily due to lower stem cell diversity. Surprisingly, despite the intense stress of the transplant process, stem cells acquired very few new genetic mutations as they rapidly divided to rebuild the patient’s blood, challenging previous assumptions regarding high mutation rates during transplantation.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The research also identified genetic factors that help certain stem cells thrive after transplantation, regardless of donor age. Understanding these advantages could pave the way for developing better treatments and improving transplant safety and efficacy for a broader range of patients.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Dr. Michael Spencer Chapman, the study\'s first author at the Wellcome Sanger Institute, emphasized the significance of tracking these changes, stating, \"When you receive a transplant, it\'s like giving your blood system a fresh start, but what actually happens to those stem cells? Until now, we could only monitor blood counts for signs of recovery. This study traces decades of changes in a single sample, revealing how certain cell populations thrive while others diminish, ultimately shaping a patient\'s blood over time.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Dr. Markus Manz, senior author at the University of Zurich, noted the importance of donor age in transplant success, asserting, \"While the hematopoietic stem cell system is remarkably stable over time, younger donors generally provide a larger and more diverse range of stem cells, which may be crucial for long-term recovery. We hope to explore other factors affecting long-term stem cell dynamics to optimize donor selection and recipient bone-marrow environments for better stem cell function.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Dr. Peter Campbell, another senior author at the Wellcome Sanger Institute, explained how the transplant process creates a genetic \'bottleneck\' for blood and immune cells. Their new approach enables them to investigate this bottleneck phenomenon more closely, identifying opportunities for specific stem cells to thrive in the recipient\'s new environment. Understanding which genes help some stem cells succeed could lead to improvements in the transplant procedure, enhancing the chances of successful outcomes for patients.</p>','2024-11-02 08:26:03.942788','uploads/news/images_16.jpeg',1,'Wellcome Trust Sanger Institute','A groundbreaking study by researchers from the Wellcome Sanger Institute and University of Zurich tracks stem cell dynamics for decades post-transplant, revealing crucial insights into donor age impacts and genetic factors that affect transplant success, paving the way for improved patient outcomes.',1,29,'<ul>\r\n                <li>Michael Spencer Chapman, C.

In a recent study published in *PLOS ONE*, researchers compared the weight loss results from low-fat and ketogenic diets, with and without ketone supplements, and found promising outcomes among pre-menopausal participants.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Of the 13 participants who achieved nutritional ketosis, 11 reported changes in their menstrual frequency or intensity during the intervention, while those on low-fat diets reported no changes. All participants lost a similar relative percentage of weight during the study, which lasted six weeks. Madison Kackley, the lead author and a research scientist at Ohio State University, highlighted a remarkable outcome: \"There were six women who hadn\'t had a period in over a year — who felt like their typical cycles were over. And their periods actually restarted on the diet.\" This suggests that the presence of ketones may influence women\'s health by regulating endocrine, cognitive, and metabolic factors.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The study involved 19 women, divided into three groups: seven on a ketogenic diet alone, six on a keto diet with ketone salt supplements, and six on a low-fat diet. Researchers provided all meals during the study, which led to clinically significant weight loss, reductions in body fat, improved cholesterol levels, and enhanced insulin sensitivity across both diet groups.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Interestingly, participants\' self-reports regarding their menstrual cycles were unexpected. Kackley noted, \"It\'s not a validated survey, but when we reviewed responses, we realized we were changing the majority of these women\'s cycles. Even for women who had normal menstrual cycles, their frequency changed.\" One participant, aged 33 and who had never had a period, experienced her first menstruation after just five days in nutritional ketosis. Notably, women who reported menstrual changes were not on birth control, whereas those who reported no changes were using oral contraceptives.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">While ketone salts did not lead to improved weight or health markers, all women on the keto diet exhibited high ketone levels, indicating a potentially individualized effect of added ketones. Kackley explained, \"It was just the presence of ketones that essentially changed the menstrual cycle. If we\'re looking for that signaling effect rather than just a weight loss effect, ketone supplementation could actually play a role in hormonal regulation.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Looking ahead, Kackley aims to further investigate the mechanisms behind this association, having established a new lab at Ohio State focused on the links between nutrition, exercise, and women\'s health. Her team is monitoring a pilot group of women to gather comprehensive data on the changes that occur during menstrual cycles, including muscle strength, fat composition, water retention, energy expenditure, hormone levels, and body temperature. Kackley believes this data will shed light on cyclical changes related to nutrition and exercise.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">This research holds significant importance, especially since 5 to 7% of women of reproductive age in the U.S. experience three months without a period annually.

However, recent excavations have revealed exceptional sites that offer new insights into the early stages of urbanization in this region. In their study, Charloux and colleagues present a detailed analysis of the Bronze Age town of al-Natah, located in Medinah province and occupied from around 2400 to 1500 BCE. This ancient town spanned approximately 1.5 hectares, featuring a central district and a nearby residential area surrounded by protective ramparts. The presence of a necropolis, characterized by burial practices indicative of social stratification, suggests a complex societal structure.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The researchers estimate that al-Natah was home to around 500 residents. While its size and organization bear similarities to other sites of the same age in northern Arabia, these sites are generally smaller and exhibit less socio-political complexity than their contemporaries in the Levant and Mesopotamia. The authors propose that al-Natah reflects a state of \'low urbanization,\' representing a transitional phase between mobile pastoralism and more complex urban settlements.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Archaeological evidence indicates that northern Arabia was characterized by small fortified towns during the Early to Middle Bronze Age, a period when other regions were experiencing advanced stages of urban development. The authors note that further excavations across Arabia will enhance our understanding of the timing of this urban transition and the corresponding changes in societal structure and architecture. They highlight that, for the first time in northwestern Arabia, archaeologists have discovered a small Bronze Age town connected to a vast network of ramparts, raising intriguing questions about the early development of urbanism in the region.</p>','2024-11-02 08:28:36.114897','uploads/news/images_14.jpeg',1,'PLOS','A new study reveals the Bronze Age town of al-Natah in northwestern Arabia, shedding light on the early urbanization process and social structures during the third to second millennium BCE.',1,170,'<ul>\r\n                <li>Guillaume Charloux, Shadi Shabo, Bruno Depreux, Sylvain Colin, Kévin Guadagnini, François Guermont, Sabine Dupuy, Mylène Bussy, Noisette Bec Drelon, Modwene Poulmarc’h, Diaa Albukaai, Saifi Alshilali, Rémy Crassard, Munirah AlMushawh.

In this study, Wendt and colleagues sought to identify the dominant large herbivores that roamed the northern Yellowstone area by analyzing preserved steroids from animal dung found in lake sediments dating back to around 238 B.C.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">To conduct their analysis, the researchers first identified the types of steroids present in the dung of various large herbivores believed to have inhabited the region, including bison, elk, moose, mule deer, and pronghorn. They found that while moose, pronghorn, and mule deer could be distinguished based on the steroids in their dung, bison and elk were more challenging to differentiate.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">By examining the steroids across different sediment layers, the researchers determined that either bison, elk, or a combination of both had been the primary large herbivore species in the watershed over the last 2,300 years. Interestingly, the analysis revealed elevated steroid levels during the 20th century, a period marked by hunting restrictions, diminished winter migrations for bison and elk, and the eradication of their natural predators.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The study also indicated that the increased populations of these large herbivores likely overgrazed local forage plants, such as willow and Idaho fescue, and their dung may have contributed to the fertilization of diatom growth in the lake, thereby altering the local ecosystem. Additionally, provisions of winter hay supplied by park managers encouraged animals to remain in the area longer, further impacting the watershed.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">This research illustrates that analyzing steroids in lake sediments is a promising method for wildlife managers and conservationists seeking to understand the historical dynamics of hoofed animal communities and their ecological impacts.

In particular, plants require boron, absorbed through boric acid channels. A research team led by Professor Junpei Takano at Osaka Metropolitan University\'s Graduate School of Agriculture has made important discoveries regarding the transport of these channels, focusing on a mutant line of *Arabidopsis thaliana*.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The study identified a mutant in which boric acid channels were not successfully transported to the plasma membrane due to a deficiency in the protein KAONASHI3 (KNS3). This protein’s name, meaning \"faceless\" in Japanese, was first given by a research team under Nagoya University Associate Professor Sumie Ishiguro in 2008. The current research delves into the transport mechanism of boric acid channels and reveals that KNS3, along with two homologous proteins—KNSTH1 and KNSTH2—form a protein complex crucial for moving these channels from the endoplasmic reticulum to the Golgi apparatus and ultimately to the plasma membrane.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">In addition to their role in nutrient transport, KNS3 and its homologs also influence pollen structure. Normally, the pollen of *Arabidopsis thaliana* displays a patterned surface reminiscent of muskmelon skin. However, in mutant strains lacking the KNS3 gene\'s protein-encoding function, this distinctive pattern disappears, rendering the pollen \"faceless.\" This loss of pattern may indicate abnormal transport of proteins unrelated to the boric acid channel, suggesting a broader role for KNS3 in plant biology.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Professor Takano noted, \"Based on the mechanism of intracellular transport of membrane proteins revealed in this study, plants might regulate nutrient uptake and pollen structure by controlling the transport of specific proteins via the KNS3-KNSTH1-KNSTH2 complex.

Conducted by an international team of paleobiologists, the research indicates that the large snout sinuses of these prehistoric reptiles prevented them from exploring deeper waters, a significant constraint not faced by cetaceans, which evolved from land mammals into fully aquatic creatures over a span of approximately 10 million years.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">During their evolutionary transition, cetaceans experienced a reduction in bone-enclosed sinuses and developed air sacs outside of their skulls. This adaptation allowed them to withstand the pressure increases associated with deep diving, enabling them to reach extraordinary depths—hundreds of meters for dolphins and thousands for whales. Thalattosuchians lived during the Jurassic and Cretaceous periods and are classified into two primary groups: Teleosauridae, which were similar to modern gharial crocodiles and likely inhabited coastal waters and estuaries, and Metriorhynchidae, which were fully adapted to marine life, exhibiting streamlined bodies and flipper-like limbs.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Researchers from the University of Southampton, University of Edinburgh, and other institutions aimed to determine whether thalattosuchians had developed sinus adaptations comparable to those of cetaceans. They employed computed tomography to analyze the sinuses of 11 thalattosuchian skulls alongside those of 14 modern crocodile species and six other fossil species.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The findings revealed a reduction in braincase sinuses as thalattosuchians evolved towards a more aquatic lifestyle, mirroring the evolutionary trajectory of cetaceans. Dr. Mark Young, the lead author from the University of Southampton, explained, \"The regression of braincase sinuses in thalattosuchians reflects the changes seen in cetaceans, diminishing during their semi-aquatic phases and further as they became fully aquatic. Both groups developed extracranial sinuses; however, the expansive snout sinus systems in metriorhynchids restricted their ability to dive deeply.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">At greater depths, the air within the sinuses would compress, leading to discomfort and potential damage due to the inability to equalize pressure. Unlike cetaceans, which have evolved highly efficient kidneys to filter salt from seawater, thalattosuchians likely relied on salt glands for excretion. The researchers propose that the complex snout sinuses in metriorhynchids may have played a role in draining their salt glands, similar to the behavior observed in modern marine iguanas. Dr. Young elaborated, \"When metriorhynchids\' sinuses experienced a contraction effect similar to a sneeze, it could have expelled excess salt, mitigating the issue of \'encrustation\' that affects animals with salt glands.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">This study sheds light on the major evolutionary transitions influenced by species\' anatomy and biology. Dr. Julia Schwab, a coauthor from the University of Manchester, remarked on the fascinating adaptations of thalattosuchians to ocean life, highlighting both their similarities and differences from modern cetaceans. Although thalattosuchians became extinct during the Early Cretaceous period, Dr. Young concluded, \"We can only speculate whether, given more evolutionary time, they might have further converged with modern cetaceans or if their need to drain salt glands presented an insurmountable barrier to further aquatic specialization.\" The research was funded by the Leverhulme Trust.</p>','2024-11-02 08:33:38.391471','uploads/news/images_11.jpeg',1,'University of Southampton','An international study reveals that the sinuses of thalattosuchians, ancient relatives of crocodiles, limited their ability to evolve into deep-diving creatures like whales and dolphins, providing insights into evolutionary adaptations to ocean life.',1,64,'<ul>\r\n                <li>Mark T.

Published in *Nature Energy*, this study highlights a modular, three-chamber reactor that incorporates a specially engineered porous solid electrolyte layer at its core, paving the way for more agile and scalable strategies to mitigate carbon dioxide emissions.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Haotian Wang, a chemical and biomolecular engineer at Rice and the study\'s corresponding author, emphasized the significance of this advancement, stating, \"Our research findings present an opportunity to make carbon capture more cost-effective and practically viable across a wide range of industries.\" The newly developed reactor demonstrates impressive industrial rates for regenerating carbon dioxide from carbon-containing solutions, showcasing long-term stability and adaptability to various cathode and anode reactions.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">One of the key advantages of this technology is its flexibility. Wang explained that the reactor operates with different chemistries and can coproduce hydrogen, which may lead to lower capital and operational costs for producing net-zero fuels or chemicals. Unlike conventional direct air capture processes that typically rely on high temperatures and chemical reactions to filter carbon dioxide, this new approach uses electrical energy at room temperature, avoiding the need for additional chemicals and eliminating unwanted byproducts.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Zhiwei Fang, a postdoctoral researcher and co-first author of the study, noted that traditional DAC technologies often depend on high-temperature processes to regenerate carbon dioxide from sorbents, which can be energy-intensive. \"Our work focused on using electrical energy instead of thermal energy to regenerate carbon dioxide,\" Fang explained. This method allows for the efficient splitting of carbonate and bicarbonate solutions, resulting in the production of alkaline absorbents in one chamber and high-purity carbon dioxide in another.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The team’s reactor optimizes electrical inputs to enhance ion movement and mass transfer, effectively reducing energy barriers. While amine-based sorbents are widely used for their relatively weak bonds that facilitate easier carbon dioxide extraction, they are also toxic and unstable. Conversely, water-based solutions like sodium hydroxide and potassium hydroxide, although greener, require much higher temperatures to release carbon dioxide. Wang’s innovative reactor addresses these challenges by efficiently managing the regeneration process.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Wang expressed hope that this research will inspire more industries to adopt sustainable practices and contribute to the momentum towards achieving a net-zero future.

This evolutionary coupling may have hindered bats from occupying as many ecological niches as their avian counterparts.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Andrew Orkney, a postdoctoral researcher in Brandon Hedrick\'s lab, expressed surprise at the findings, stating, \"We initially expected to confirm that bat evolution is similar to that of birds, and that their wings and legs evolve independently of one another. The fact we found the opposite was greatly surprising.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The study, published on November 1 in *Nature Ecology and Evolution*, challenges the long-held belief that the independent evolution of forelimbs and hindlimbs was essential for the origin of flight in vertebrates. Since legs and wings perform distinct functions, researchers had assumed that this independence would allow for greater adaptability to their specific roles.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">By comparing bats and birds—two groups that do not share a common flying ancestor—the researchers could effectively test this hypothesis. They found that within each species, the shapes of bones in the wings (including the handwing, radius, and humerus) or the legs (like the femur and tibia) evolve together, showing strong correlations. However, a stark contrast emerged when examining the correlation between legs and wings: bird species exhibited little to no correlation, while bats displayed a significant correlation.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">This means that, unlike birds, bats’ forelimbs and hindlimbs did not evolve independently. Instead, changes in wing shape—whether an increase or decrease—were accompanied by corresponding changes in leg shape.

This new physics-based computer modeling framework integrates indices of human comfort and social vulnerability with heat island mitigation strategies and advanced urban climate modeling. The findings were published in *PNAS Nexus*.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">In their application of this index to Houston, the researchers discovered that trees, rather than roof treatments, offered the best relief from heat in the most vulnerable areas of the city. Vulnerability was assessed based on factors such as socioeconomic status, household composition, and minority status, alongside adaptive capacity indicators like housing type and access to transportation.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Heat islands occur in urban areas where buildings and roads absorb more sunlight than natural landscapes, leading to elevated temperatures, increased energy consumption, and compromised human health and comfort. This effect varies significantly across different neighborhoods, intensifying the challenge for city planners.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The research introduces the universal thermal comfort index, which takes into account temperature, humidity, wind speed, and solar radiation to quantify how urban heat affects human comfort. Prior studies had largely overlooked the impact of direct sunlight on comfort levels in urban environments. \"For construction workers working under direct sunlight versus those shaded by trees, comfort levels will differ dramatically,\" explained Zong-Liang Yang, one of the lead researchers.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The study examined three heat island mitigation strategies: painting roofs white to enhance solar reflectance, implementing vegetation on roofs for increased evaporation, and planting trees for shade and cooling. While painting roofs white resulted in the most significant decrease in heat index during the day in a generic city block, the outcomes varied when considering different neighborhoods in Houston.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Utilizing the social vulnerability index developed by the U.S. Centers for Disease Control and Prevention, the researchers classified Houston neighborhoods by their vulnerability levels. Their analysis revealed that in areas with lower vulnerabilities, painting roofs white was the optimal cooling strategy, while in more vulnerable neighborhoods, planting trees proved to be more effective. \"By combining the cooling index with vulnerability data, we can pinpoint which methods will offer more relief to at-risk neighborhoods,\" said lead author Kwun Yip Fung, who conducted this research as part of his doctoral studies.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Interestingly, neighborhoods with higher vulnerability also had more available space for tree planting, while they had less roof area suitable for painting or vegetation. \"Now that we know vulnerable neighborhoods have more room for trees, we should prioritize tree planting in those areas,\" Fung stated. Conversely, in less vulnerable areas, strategies like cool roofs and green roofs should take precedence.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Adapting this methodology to other cities will require additional considerations, such as selecting heat and drought-tolerant trees in arid regions like Arizona, or addressing the absence of air conditioning in northern communities vulnerable to heat. The researchers envision that their methodology could also support hybrid strategies, integrating both rooftop treatments and tree planting, alongside reflective pavements. \"This is just the beginning; our index and methodology can be applied to numerous scenarios moving forward,\" Fung concluded.</p>','2024-11-03 06:58:21.088263','uploads/news/images_7.png',1,'University of Texas at Austin','Researchers at The University of Texas at Austin have created a new tool to identify effective strategies for urban heat mitigation, revealing that tree planting is more beneficial than roof treatments in vulnerable Houston neighborhoods.',1,164,'<ul>\r\n                <li>Kwun Yip Fung, Zong-Liang Yang, Alberto Martilli, E Scott Krayenhoff, Dev Niyogi.

Lead author Honorary Professor Graham Pyke from Macquarie University emphasized that these findings illuminate a common yet poorly understood process in plant biology. \"Our research delivers the first direct demonstration that plants can salvage resources from wilting flowers and reuse these resources to promote future reproduction,\" he stated.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The three-year study concentrated on *Blandfordia grandiflora*, commonly known as Christmas Bells, a perennial species native to eastern Australia that typically flowers in December. Characterized by its vibrant red and yellow blooms, Christmas Bells are often found in flower markets both locally and internationally. The research took place on a plantation encompassing several hectares of native wet heath, where Christmas Bells bloom profusely alongside a commercial shadehouse.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Using various techniques, the team controlled pollination and the wilting process of the flowers, subsequently examining the effects on seed production and reflowering. Surprisingly, they discovered that the plants did not use resources from wilted flowers to enhance short-term reproduction. Instead, these plants salvage resources invested in reproduction during one flowering season and store them for use during the next.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Specifically, *Blandfordia grandiflora* transfers energy and nutrients from its wilting flowers to underground corms and roots, which then support the production of new flowering stems in the subsequent season, typically a year later. Professor Pyke described the plant\'s strategy as a fascinating example of resource management and economic decision-making. \"Plant economics are all about trade-offs. Plants must decide where to allocate their limited resources; investing in one area means they can\'t invest as much in another.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">This study reveals that plants are not just focusing on immediate reproduction but are strategically saving resources for future growth. Professor Pyke noted the diverse strategies plants have developed for managing their flowers after their primary reproductive function, with wilting being one of several approaches. He pointed out that not all plants adhere to the flower wilting pattern; some flowers continue to bloom long after they can be fertilized or stop producing nectar, thereby enhancing the plant\'s attractiveness to pollinators.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">To further validate their findings, the researchers conducted experiments comparing seed production between plants with wilting flowers and those with petals removed to prevent wilting. They also examined plants where seed production was entirely prevented while allowing wilting in some. The results indicated that plants with wilting flowers had a higher likelihood of reflowering the following season compared to those where wilting was prevented.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Other factors influencing seed production were also evaluated, including flowering stem height, number of flowers per stem, and flower position. Taller stems produced more and heavier seeds, while flowers positioned lower on the plant tended to yield fewer and lighter seeds. Professor Pyke concluded that their findings open up new avenues for research into other plant species and how they manage and reuse resources from wilting flowers. Future studies could investigate the composition of these salvaged resources and assess whether the benefits of conserving them outweigh the costs of initial flower production.</p>','2024-11-03 06:59:04.710307','uploads/news/images_48.jpeg',1,'Macquarie University','A study reveals that *Blandfordia grandiflora* (Christmas Bells) can salvage resources from wilting flowers to enhance future reproduction, challenging previous assumptions about plant resource allocation.',1,10,'<ul>\r\n                <li>G.

This rule, known as Bredt\'s rule, asserts that molecules cannot have a carbon-carbon double bond at the ring junction of a bridged bicyclic molecule, also referred to as the \"bridgehead\" position. Traditionally, olefins, which are characterized by double bonds between carbon atoms, are expected to maintain a specific geometry, with atoms lying in the same 3D plane. Bredt\'s rule, introduced in 1924, suggests that double bonds at these junctions would lead to distorted shapes inconsistent with the rigid geometry of alkenes.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">This long-held belief has limited the types of synthetic molecules chemists could conceive and, consequently, hindered potential applications in pharmaceutical research. However, a new study published in the journal *Science* by UCLA scientists has overturned this notion, demonstrating the feasibility of synthesizing molecules known as anti-Bredt olefins (ABOs). Corresponding author Neil Garg, the Kenneth N. Trueblood Distinguished Professor of Chemistry and Biochemistry at UCLA, emphasizes that the perception of ABOs as unattainable has stifled innovation. \"We shouldn\'t have rules like this -- or if we have them, they should only exist with the constant reminder that they\'re guidelines, not rules. It destroys creativity when we have rules that supposedly can\'t be overcome,\" Garg stated.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">In their research, Garg\'s lab employed a technique involving the treatment of silyl (pseudo)halides with a fluoride source to initiate an elimination reaction that produces ABOs.

Garg noted, \"There\'s a big push in the pharmaceutical industry to develop chemical reactions that yield three-dimensional structures like ours because they can be used to discover new medicines. This study shows that, contrary to one hundred years of conventional wisdom, chemists can make and use anti-Bredt olefins to create valuable products.\" The research involved contributions from UCLA graduate students and postdoctoral scholars, alongside collaboration with computational chemistry expert Ken Houk.

Echolocating bats face a similar challenge, using sound waves instead of light. While bats have long been recognized for their echolocation abilities to avoid obstacles, this research led by Aya Goldshtein demonstrates that they can also identify their location after being displaced and navigate using an internal map.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The study focused on Kuhl\'s pipistrelle (Pipistrellus kuhlii), a bat species weighing just 6 grams, in Israel\'s Hula Valley. Over several nights, the researchers tracked 76 bats near their roosts and relocated them within a three-kilometer radius. The bats were equipped with an innovative lightweight reverse GPS tracking system called ATLAS, which allowed for high-resolution tracking. While some bats were solely fitted with the ATLAS system, others underwent additional manipulations to assess how various senses influenced their navigation.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Remarkably, 95 percent of the bats were able to return to their roosts within minutes, relying solely on echolocation. This finding underscores the efficiency of their navigation abilities, even with a highly directional sensory system. Notably, when vision was available, bats demonstrated improved navigation. Goldshtein remarked, \"We were surprised to discover that these bats also use vision... even with such small eyes, they can rely on vision under these conditions.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">In addition to field experiments, the research team created a detailed map of the Hula Valley to visualize the bats\' experiences during flight.

They utilized *Caenorhabditis elegans* (C. elegans), a roundworm model organism, to investigate the effects of this genetic variant. Their findings revealed that the worms with the patient’s mutation exhibited slower movement compared to those with a healthy gene copy, indicating that the genetic change impacts mobility and nervous system function.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The CCT3 protein is part of the TRIC/CCT molecular complex responsible for proper protein folding within cells. The study showed that insufficient levels of healthy CCT3 hinder the protein-folding machinery, leading to misfolded actin proteins, which are critical for cell shape and movement. Co-author Tim Schedl noted, \"Our studies revealed that the genetic change reduces the activity of the normal protein, decreasing the capacity of the protein-folding machinery.\"</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">To broaden their search for additional cases, the researchers analyzed a global database of individuals with intellectual and developmental disabilities, identifying 22 patients with genetic alterations in several CCT proteins forming the protein-folding machine.

These devices, made from a soft polymer called azobenzene, are battery-free and subcellular-sized, allowing them to gently wrap around neuronal structures like axons and dendrites without causing damage. Activated by light, these wireless devices can snugly enfold the neuronal processes, enabling the measurement of electrical and metabolic activity at a subcellular level.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The concept allows for thousands of these tiny devices to be injected into the body, where they can be actuated noninvasively. By controlling the dose of light, researchers can precisely manipulate how these devices wrap around cells, potentially aiding in restoring neuronal degradation seen in diseases like multiple sclerosis. \"The concept and platform technology we introduce here is like a founding stone that brings about immense possibilities for future research,\" says Deblina Sarkar, senior author of the study published in *Nature Communications Chemistry*.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The researchers faced challenges in creating bioelectronic implants that conform to the complex shapes of brain cells, which can vary widely in length and curvature. To address this, they developed thin-film devices that roll into microtubes when exposed to light, allowing them to gently wrap around highly curved axons and dendrites. By fine-tuning the intensity and polarization of the light, they can control the devices’ rolling diameter, enabling a snug fit around the fragile neuronal structures.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The fabrication process involved depositing azobenzene onto a water-soluble sacrificial layer, molding it with a stamp to create thousands of tiny devices, and using light to actuate them. The devices maintained their shape for days post-illumination, and biocompatibility tests showed that they could tightly wrap around rat neurons without causing harm.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The potential applications of these devices are significant, including their use as synthetic myelin to restore insulation around damaged axons, a critical function lost in conditions like multiple sclerosis. The researchers also plan to integrate the devices with optoelectrical materials for cell stimulation and to pattern atomically thin materials for enhanced functionality.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Sarkar expressed excitement over the intimate interface achieved between the devices and living cells, stating, \"We have shown that this technology is possible,\" and highlighted the potential for these devices to modulate neuronal activity with minimal energy requirements, paving the way for new treatments for brain diseases.</p>','2024-11-03 07:16:30.218164','uploads/news/images_41.jpeg',1,'Massachusetts Institute of Technology','MIT researchers have created battery-free wearable devices that wrap around neurons to measure and modulate their activity, potentially aiding in the treatment of neurodegenerative diseases.',1,134,'<ul>\r\n                <li>Marta J.

This acceleration, primarily attributed to intensified atmospheric winds, has resulted in stronger and shallower oceanic currents, which may affect both regional and global climate patterns, including the frequency and intensity of El Niño and La Niña events.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">Led by Franz Philip Tuchen, a postdoctoral scientist at the University of Miami\'s Rosenstiel School\'s NOAA Cooperative Institute for Marine and Atmospheric Studies (CIMAS), the research team collaborated with NOAA\'s Atlantic Oceanographic and Meteorological Laboratory (AOML) to synthesize three decades of ocean and atmosphere observations. They utilized data from satellites, mooring buoys, and ocean surface drifters to create a comprehensive view of changes in the Pacific upper-ocean circulation.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">The study indicates that stronger winds across the equatorial Pacific have accelerated westward near-surface currents by approximately 20 percent in the central equatorial Pacific. Additionally, poleward currents north and south of the equator have increased by 60 percent and 20 percent, respectively. Tuchen noted that the equatorial thermocline, a crucial ocean layer for El Niño-Southern Oscillation (ENSO) dynamics, has steepened significantly. \"This steepening trend could reduce ENSO amplitude in the eastern Pacific and favor more frequent central Pacific El Niño events,\" he explained, indicating potential alterations to regional and global climate patterns.</p>\r\n<p class=\"reg-normal\"></p>\r\n<p class=\"reg-normal\">This study provides a benchmark for climate models that have struggled to accurately represent Pacific circulation and sea surface temperature trends. The findings could enhance the predictability of ENSO events and their associated weather patterns, especially in regions like the United States that experience significant climate variability from these changes. Funding for this research was provided by NOAA\'s Global Ocean Monitoring and Observing (GOMO) programs, including the Global Tropical Moored Buoy Array (GTMBA), the Global Drifter Program (GDP), and the Tropical Atmosphere Ocean (TAO) program.</p>','2024-11-03 07:17:06.590982','uploads/news/images_40.jpeg',1,'University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science','A study reveals a significant acceleration of upper-ocean circulation in the equatorial Pacific, driven by intensified winds, with implications for climate patterns and ENSO events.',1,45,'<ul>\r\n                <li>Franz Philip Tuchen, Renellys C.
