Why yawns are contagious—in all kinds of animals - Last Episode Evolutionary biologist Andrew Gallup explains why we yawn after others Continuation from last episode, Q: Do all animals yawn the same way? A:  We’ve done a number of large-scale comparative studies, where we’ve recorded the yawn durations from over 100 mammalian and avian species. We find that even when controlling for body size, there are very strong positive relationships between how long an animal yawns and how large and complex their brain is. Q: One of the most curious things about yawning is that it can be contagious. Do all animals yawn contagiously? A: We’ve been talking about spontaneous yawns up to this point—those are internally, physiologically driven. Contagious yawns are elicited by seeing or hearing yawns in others, and [they] have only been documented in highly social species, humans included. There’s a wide variability in that response among individuals. Some individuals are very susceptib...

Why yawns are contagious—in all kinds of animals Evolutionary biologist Andrew Gallup explains why we yawn after others The mere sight of another person yawning causes many of us to open our mouths wide in mimicry. And we’re not alone—other social animals, such aschimpanzees and lions, can also catch so-called contagious yawns. It’s likely that all vertebrates yawn spontaneously to regulate inner body processes. Yawning probably arose with the evolution of jawed fishes 400 million or so years ago, says Andrew Gallup, an evolutionary biologist at State University of New York Polytechnic Institute who has spent years trying to figure out why we yawn. In a paper published this month in  Animal Behavior , he reports  some evidence  for how contagious yawns might have evolved to keep us safe.  Science  chatted with Gallup about why yawning is ubiquitous—and useful. This interview has been edited for clarity and length Q: First, let’s address a long-standi...

Nanomaterial could enhance diabetes treatment Conventional treatments for diabetes can increase the risk of neurological problems, an under-researched side effect.  U.S. National Science Foundation -supported scientists based at  The Ohio State University  developed a nanomaterial that binds insulin to a group of amino acids that includes antioxidants. The nanomaterial improved glucose consumption, leading to better brain function. When compared to mice treated with insulin alone, mice treated with the nanomaterial had improved glucose control and cognition outcomes.  The researchers published their findings in  Biomaterials . "We found in mice that our molecule and insulin combined was better than each treatment alone in reversing diabetes-related problems, and produced dramatically improved cognitive performance compared to all other groups," said Ouliana Ziouzenkova, senior author of the study. The beneficial results could be caused by the nanomat...

A first: Scientists grow plants in soil from the Moon      Scientists have grown plants in soil from the Moon, a first in human history and a milestone in lunar and space exploration. In a new paper published in the journal Communications Biology, University of Florida researchers showed that plants can successfully sprout and grow in lunar soil. Their study also investigated how plants respond biologically to the Moon's soil, also known as lunar regolith, which is radically different from soil found on Earth. This work is a first step toward one day growing plants for food and oxygen on the Moon or during space missions. More immediately, this research comes as the Artemis Program plans to return humans to the Moon. "Artemis will require a better understanding of how to grow plants in space," said Rob Ferl, one of the study's authors and a distinguished professor of horticultural sciences in the UF Institute of Food and Agricultural Sciences (UF/IFAS). Ev...

Rewriting the history books: Why the Vikings left Greenland One of the great mysteries of late medieval history itheorthe Norse, who established successful settlements in southern Greenland in 985, abandoned them in the early 15th century. The consensus view has long been that the colder temperatures of the Little Ice Age helped make the colonies unsustainable. However, new research, led by scientists at the  University of Massachusetts .  It wasn't dropping temperatures that helped drive the Norse from Greenland, but drought. The research was supported by the  U.S. National Science Foundation . "The team found no substantial temperature changes, but found a persistent drying period," says Colene Haffke, a program director in NSF's Office of Polar Programs. When the Norse thrived in Greenland in what they called the Eastern Settlement in 985, they made their way by clearing the land of shrubs and planting grass as pasture for their livestock. The populatio...

Scientists resurrect ancient enzymes to improve photosynthesis A Cornell University study describes a breakthrough in the quest to improve photosynthesis in certain crops, a step toward adapting plants to rapid climate changes and increasing yields to feed a projected 9 billion people by 2050. The study, "Improving the Efficiency of Rubisco by Resurrecting Its Ancestors in the Family Solanaceae," published April 15 in Science Advances. The senior author is Maureen Hanson, the Liberty Hyde Bailey Professor of Plant Molecular Biology in the College of Agriculture and Life Sciences. First author Myat Lin is a postdoctoral research associate in Hanson's lab. The authors developed a computational technique to predict favorable gene sequences that make Rubisco, a key plant enzyme for photosynthesis. The technique allowed the scientists to identify promising candidate enzymes that could be engineered into modern crops and, ultimately, make photosynthesis more efficie...

How do our eyes stay focused on what we reach for? Keeping our eyes focused on what we reach for, whether it be an item at the grocery store or a ground ball on the baseball field, may appear seamless, but, in fact, is due to a complex neurological process involving intricate timing and coordination. In a newly published study in the journal Nature, a team of researchers sheds additional light on the machinations that ensure we don't look away from where we are reaching. The work centers on a form of coordinated looking and reach called "gaze anchoring" -- the temporary stoppage of eye movements in order to coordinate reaches. "Our results show that we anchor our gaze to the target of the reach movement, thereby looking at that target for longer periods," explains Bijan Pesaran, a professor at NYU's Center for Neural Science and one of the paper's authors. "This is what makes our reaches much more accurate. The big question has been: How...

Kitchen sponge a better incubator for bacterial diversity than a laboratory petri dish Researchers at Duke University have uncovered a basic but surprising fact: A kitchen sponge is a better incubator for diverse bacterial communities than a laboratory petri dish. But it's not just the trapped leftovers that make the cornucopia of microbes swarming around so happy and productive, it's the structure of the sponge itself. In a series of experiments, the scientists show that various microbial species can affect one another's population dynamics depending on structural environment factors such as complexity and size. Some bacteria thrive in a diverse community while others prefer a solitary existence. And a physical environment that allows both to live their best lives leads to the strongest levels of biodiversity. Soil provides that optimal mixed-housing environment -- and so does a kitchen sponge. Bacteria are just like people living through the pandemic -- some f...

Scientists develop gel that delivers drugs directly to diseased joints Osteoarthritis (OA) is a progressive condition affecting the lives of more than 32 million Americans. Post-traumatic osteoarthritis (PTOA), a major subset of osteoarthritis that comprises 10% of diagnoses and disproportionally affects injured military personnel, has no effective therapeutic protocols that slow or stop the progression except for over-the-counter analgesics. Post-traumatic osteoarthritis leads to articular cartilage damage and results in more than $3 billion in health care costs each year. researchers based at New York University identified the molecular mechanism and therapeutic payload for delivering pharmacologic treatment directly to affected joints, effectively halting the onset and progression of post-traumatic osteoarthritis The researchers combined compounds to develop a porous gel that can reach and envelop affected joints, reduce inflammation and induce regeneration. The substanc...

Scientists identify neurons in the brain that drive competition and social behavior within groups New research in mice has identified neurons in the brain that influence competitive interactions between individuals and that play a critical role in shaping the social behavior of groups. Published in Nature by a team led by investigators at Massachusetts General Hospital (MGH), the findings will be useful not only for scientists interested in human interactions but also for those who study neurocognitive conditions such as autism spectrum disorder and schizophrenia that are characterized by altered social behavior. "Social interactions in humans and animals occur most commonly in large groups, and these group interactions play a prominent role in sociology, ecology, psychology, economics and political science," says lead author S. William Li, an MD/PhD student at MGH. "What processes in the brain drive the complex dynamic behavior of social groups remains poorl...

Novel analysis finds new mechanism underlying red blood cell aging Scientists have found a new mechanism underlying red blood cell aging. Red blood cells, the most abundant cell type in blood, carry oxygen throughout the human body. In blood circulation, they repeatedly encounter various levels of oxygen tension. Hypoxia, a low oxygen condition, is a very common micro-environmental factor in physiological processes of blood circulation and in conditions such as cancer, chronic inflammation, heart attacks and stroke In addition, a connection between poor cellular deformability -- the ability of blood cells to change shape in response to different levels of stress -- and impaired oxygen delivery is found in various pathological processes such as sickle cell disease. Sickle red blood cells simultaneously undergo drastic mechanical deformation during the sickling and unsickling process. The interactions between hypoxia and cell biomechanics and the underlying mechanisms of the ...

HEALTH CONSEQUENCE OF CAFFEINE Many of us rely on a morning cup of coffee or a jolt of caffeine in the afternoon to help us get through the day. caffeine is widely available to everyone,especially in u.s which made the u.s food and drug administration (FDA) , says about 80 percent of u.s adult take some form of caffeine everyday. Taking caffeine does more than just keeping you awake. Caffeine is a central nervous system stimulant that functionally affect your body in many ways. However, caffeine provides no nutritional value on its own,that is, it is tasteless, to the fact that you may not know if it is in your food. Infact, some of the medications you take might contain caffeine without your knowledge . Do you know that caffeine being an ingredient in your coffee causes some symptoms. After consuming caffeine, you may feel more energetic, but overtime , too much caffeine may cause withdrawal symptoms. According to mayo clinic, stated that it is safe for most healthy adult ...

New study has scientists re-evaluating brain size and mammalian intelligence How brain and body size evolved in mammals over the last 150 million years Brain size in mammals shows variation and similarities despite intelligence levels. Scientists at Stony Brook University and the Max Planck Institute of Animal Behavior have pieced together a timeline of how brain and body size evolved in mammals over the last 150 million years. The findings, published in Science Advances, show that brain size relative to body size -- long considered an indicator of animal intelligence --has not followed a stable scale over evolutionary time. The team of scientists, including biologists, evolutionary statisticians and anthropologists, compared the brain mass of 1,400 living and extinct mammals. For the 107 fossils examined -- among them ancient whales and the most ancient Old World monkey skull ever found -- they used endocranial volume data from skulls instead of brain mass data. The brain ...

First complete coronavirus model shows cooperation Frontera, Anton 2 supercomputers simulate holistic model of SARS-CoV-2 virion Supercomputers simulated a holistic model of the SARS-CoV-2 virion. The virus that causes COVID-19 holds many mysteries. Scientists remain in the dark on aspects of how it fuses and enters the host cell, and how it assembles and buds off the host cell. Computational modeling combined with experimental data provides insights into these behaviors. But modeling the dynamics of the SARS-CoV-2 virus over meaningful timescales has so far been limited to its pieces, such as the spike protein, a target for the current round of vaccines. A new multiscale coarse-grained model of the complete SARS-CoV-2 virion -- its core genetic material and shell -- has been developed for the first time using supercomputers. The model offers scientists new ways to exploit the virus's vulnerabilities. "We wanted to understand how SARS-CoV-2 works holistically as a ...

World's oldest DNA reveals how ice age mammoths evolved Discovery of new lineage, insights into when and how fast mammoths adapted to cold climate The mammoth that inhabited North America during the last ice age was a hybrid animal. An international research team has sequenced DNA recovered from mammoth remains that are up to 1.2 million years old.  The analyses, funded in part by the U.S. National Science Foundation, show that the Columbian mammoth that inhabited North America during the last ice age was a hybrid between the woolly mammoth and a previously unknown genetic lineage of mammoth. The study also provides new insights into when and how fast mammoths became adapted to cold climate. The samples are a thousand times older than Viking remains and pre-date the existence of humans and Neanderthals, say the scientists. Around one million years ago, there were no woolly nor Columbian mammoths, as they had not yet evolved. Researchers have now managed to analyze the ...
