Multifunctional computer chips have evolved to do more with integrated sensors, processors, memory and other specialized components. However, as chips have expanded, the time required to move information between functional components has also grown. “Think of it like building a house,” said Sang-Hoon Bae, an assistant professor of mechanical engineering and materials science at the McKelvey School of Engineering at Washington University in St. Louis. “You build out laterally and up vertically to get more ...

By studying the skull shapes of dipsadine snakes, researchers at The University of Texas at Arlington have found how these species of snakes in Central and South America have evolved and adapted to meet the demands of their habitats and food sources. The research, conducted in collaboration with colleagues at the University of Michigan, was published in the peer-reviewed journal BMC Ecology and Evolution. “We now have evidence that this group of snakes is one of the most spectacular and largest vertebrate adaptive radiations currently known to science,” said Gregory Pandelis, collections manager at UTA’s Amphibian and Reptile Diversity ...

INDIANAPOLIS—Indiana University researchers are collaborating on a novel approach to use neuroimaging and network modeling tools—previously developed to analyze brains of patients in the clinic—to investigate Alzheimer’s disease progression in preclinical animal models. The research team, led by Evgeny Chumin, PhD, a postdoctoral research fellow in the College of Arts and Sciences' Department of Psychological and Brain Sciences at IU Bloomington, and Paul Territo, PhD, professor of medicine at the IU School of Medicine, published their findings in Alzheimer’s & Dementia: The Journal of ...

ITHACA, N.Y. -- In sea fireflies’ underwater ballet, the males sway together in perfect, illuminated synchronization, basking in the glow of their secreted iridescent mucus. “It’s extreme,” said Nicholai M. Hensley, a postdoctoral fellow in the Department of Neurobiology and Behavior in the College of Arts and Sciences. “It’s an illustration of convergent evolution and a striking example of synchronized bioluminescent mating displays. The males are putting it all out on the dance floor. It’s a big bright display.” Hensley is the lead author of new research unwrapping the vivid mating ...

Philadelphia, November 30, 2023 – Everyone should get quality care, no matter the color of their skin. However, implicit bias, micro-aggressions, and a lack of cultural understanding persist, leading to oppression and unequal treatment in healthcare. An insightful article in the new themed issue of the Journal of Medical Imaging and Radiation Sciences on specialized populations, published by Elsevier, highlights this serious problem, specifically addressing the assessment and treatment of radiation-induced skin reactions (RISR) in patients across the world undergoing external beam radiotherapy. The article provides a stark example ...

Long before researchers discovered the electron and its role in generating electrical current, they knew about electricity and were exploring its potential. One thing they learned early on was that metals were great conductors of both electricity and heat. And in 1853, two scientists showed that those two admirable properties of metals were somehow related: At any given temperature, the ratio of electronic conductivity to thermal conductivity was roughly the same in any metal they tested. This so-called Wiedemann-Franz law has held ever since – except in quantum materials, where electrons stop behaving as individual particles and glom together into a sort of electron soup. ...

Dogs’ food preferences are mirrored in their brain activity, particularly within their caudate nuclei -a brain region associated with reward processing, a new study combining behavioural and neuroimaging data by researchers from the Department of Ethology, Eötvös Loránd University (Hungary) and Symrise Pet Food (France) finds. The study, which seamlessly blends behavioral observations with advanced neuroimaging techniques, offers novel insights into the influence of food quality on dogs' motivation. This work has been published in Scientific Reports. Similar to people, ...

Four in five primary caregivers of nine-month-old babies reported cuddling, talking and playing with their little one several times a day, in England's first national long-term study of babies in over two decades, led by UCL (University College London).  More than half engaged in physical or turn-taking play, singing, pretend games and noisy play with their babies several times a day – activities which were linked to improved early language development. Around three quarters showed their babies picture ...

The increased legalization of cannabis over the past several years can potentially increase its co-use with alcohol. Concerningly, very few studies have looked at the effects of these two drugs when used in combination. In a series of new studies, researchers at the University of Illinois Urbana-Champaign used rats to understand how brain structure and behavior can change when cannabis and alcohol are taken together. Most researchers have studied the effects of either alcohol or THC (delta-9-tetrahydrocannabinol), the primary psychoactive drug in cannabis, alone. However, when people, especially adolescents, use these drugs, ...

Scientists are working to protect the unique qualities of cacao beans grown in the Buenaventura region on the Pacific coast of Colombia. In a study published in the Journal of the Science of Food and Agriculture, researchers from the Colombian Corporation for Agricultural Research (AGROSAVIA) have examined a wealth of metrics to uncover the complex interactions between environmental factors and cacao quality. In a pioneering move, they have proposed that Buenaventura should be designated as a new Denomination of Origin (DO) for cacao trees. This is a legal recognition given to products that originate ...

By strategically straining materials that are as thin as a single layer of atoms, University of Rochester scientists have developed a new form of computing memory that is at once fast, dense, and low-power. The researchers outline their new hybrid resistive switches in a study published in Nature Electronics. Developed in the lab of Stephen M. Wu, an assistant professor of electrical and computer engineering and of physics, the approach marries the best qualities of two existing forms of resistive switches used for memory: memristors and phase-change materials. Both forms have been explored for their advantages over ...

MADISON – Nineteen million years ago, during a time known as the early Miocene, massive ice sheets in Antarctica rapidly and repeatedly grew and receded. The Miocene is widely considered a potential analog for Earth's climate in the coming century, should humanity remain on its current carbon emissions trajectory. Identifying how and why Antarctica's major ice sheets behaved the way they did in the early Miocene could help inform understanding of the sheets' behavior under a warming climate. Together, the ice sheets lock a volume of water equivalent to more than 50 meters of sea level rise and influence ocean currents that affect marine food webs and regional climates. ...

(MEMPHIS, Tenn. – November 30, 2023) Immunotherapy using modified chimeric antigen receptor (CAR) T cells has greatly improved survival rates for pediatric patients with relapsed and recurrent leukemia. However, these therapies are not as effective in treating solid tumors and can have significant toxicity. Findings from St. Jude Children’s Research Hospital showed that adding a modular chimeric cytokine receptor to CAR T cells increased their efficacy in multiple solid tumor models. The study was published today in Nature Biomedical Engineering.   “We designed modular chimeric cytokine receptors and showed that ...

Melting of glaciers, rising sea levels, extreme heat waves: the consequences of climate change are more visible than ever, and the scientific community has confirmed that humans are responsible. Yet studies show that a third of the population still doubts or disputes these facts. The cause is disinformation spread by certain vested interests. To try and prevent this phenomenon, a team from the University of Geneva (UNIGE) has developed and tested six psychological interventions on nearly 7,000 participants from twelve countries. The research, published in ...

Skin-to-skin contact between parent and infant during the first hours after a very premature birth helps develop the child's social skills. This is according to a new study published in JAMA Network Open by researchers from Karolinska Institutet and others. The study also shows that fathers may play a more important role than previous research has shown. In current practice, very premature babies are usually placed in an incubator to keep them warm and to stabilize them during the first hours after birth. In the “Immediate parent-infant skin-to-skin study” (IPISTOSS), 91 premature babies born at 28 to 33 weeks were randomized to either ...

Plants regulate their development with a distinct group of molecular players. ROP proteins, a group of plant-specific proteins, are known to control plant tissue formation. Now, Hugh Mulvey and Liam Dolan at the GMI show that ROP proteins evolved at the transition between unicellular and multicellular plant life. The findings are published on November 30 in the journal Current Biology.   Being non-mobile, plants follow a very different lifestyle from us animals. To grow and develop, plants also need a distinct ...

In a study with 22 pairs of identical twins, Stanford Medicine researchers and their colleagues have found that a vegan diet improves cardiovascular health in as little as eight weeks. Although it’s well-known that eating less meat improves cardiovascular health, diet studies are often hampered by factors such as genetic differences, upbringing and lifestyle choices. By studying identical twins, however, the researchers were able to control for genetics and limit the other factors, as the twins grew up in the same households ...

MIT geologists have found that a clay mineral on the seafloor, called smectite, has a surprisingly powerful ability to sequester carbon over millions of years.  Under a microscope, a single grain of the clay resembles the folds of an accordion. These folds are known to be effective traps for organic carbon.  Now, the MIT team has shown that the carbon-trapping clays are a product of plate tectonics: When oceanic crust crushes against a continental plate, it can bring rocks to the surface that, over ...

About The Study: In this study of 3 million U.S. adults, anxiety and depression were significantly higher among adults ages 18 to 39 compared with adults age 40 and older during the COVID-19 pandemic. Less favorable economic conditions and responses to social upheaval may have contributed to young adults’ worse mental well-being. These findings suggest a need for greater mental health care and economic policies targeted toward younger adults.  Authors: Sarah Collier Villaume, Ph.D., of Northwestern University in Evanston, ...

About The Study: The findings of this study suggest that structural racism must be considered as a fundamental contributor to the unequal distribution of lung cancer risk factors and thus disparate lung cancer risk across different racial and ethnic groups. Additional research is needed to better identify mechanisms contributing to inequitable lung cancer risk and tailor preventive interventions.  Authors: Sidra N. Bonner, M.D., M.P.H., M.Sc., of the University of Michigan in Ann Arbor, is the corresponding author. To access the embargoed study: Visit our For The Media website ...

A new analysis of the brain activity of people with post-traumatic stress disorder (PTSD) is the first to reveal that traumatic memories are represented in the brain in an entirely different way than sad autobiographical memories. This finding supports the notion that traumatic memories in PTSD are an alternate cognitive entity that deviates from regular memory, and may provide a biological explanation for why the recall of traumatic memories often displays as intrusions that differ profoundly from “regular” negative memories for patients with PTSD. The study, ...

New Haven, Conn. — It is well known that people who have lived through traumatic events like sexual assault, domestic abuse, or violent combat can experience symptoms of post-traumatic stress disorder (PTSD), including terrifying flashbacks, severe anxiety, and uncontrollable thoughts about the incident. But what exactly happens in the brains of PTSD patients as they recall these traumatic events? Are they remembered the same way as, say, the loss of a beloved pet — or, for that matter, a relaxing walk on the beach? A new study co-led by Yale researchers finds that the brain activity triggered by recollections of traumatic experiences ...

New study tackles the mystery of why bacteria often carry diverse ranges of weapons. The findings show that different weapons are best suited to different competition scenarios. Short-range weapons help bacteria to invade established communities; long-range weapons are useful once established. A new study led by the University of Oxford has shed light on why certain species of bacteria carry astonishing arsenals of weapons. The findings, published today in the journal Nature Ecology & Evolution, could help us to engineer microbes that can destroy deadly pathogens, reducing our reliance on antibiotics. Many species of bacteria possess ...
