The latest data underscores a stark gender disparity, revealing that female sihek are at greater risk for death and disease than their male counterparts.  As part of an ongoing Morris Animal Foundation-funded study, researchers at The Zoological Society ...

INDIANAPOLIS — It’s no secret that a good night’s rest can do wonders for one’s health, but those who struggle with insomnia have a nearly 50% increased risk of cardiovascular disease. One scientist in the School of Science at IUPUI will spend the next five years trying to figure out how those risks can be reduced. Jesse Stewart, a professor of psychology at the school, has received a five-year, $3 million grant from the National Institutes of Health’s National Heart, Lung and Blood Institute for a project named the Strengthening Hearts ...

EMBARGOED FOR RELEASE UNTIL 4 P.M. ET, WEDNESDAY, OCTOBER 25, 2023 MINNEAPOLIS – Older people who have higher levels of triglycerides, a type of fat, may have a lower risk of dementia and a slower cognitive decline over time compared to people who have lower levels, according to new research published in the October 25, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. While the study found a link, it does not prove that higher levels of triglycerides prevent dementia. Triglycerides are fatty acids and are the most common type of fat in the blood. Triglycerides contribute ...

In a study of different types of distraction involving more than 1,000 participants, researchers statistically derived a novel measure—dubbed the “d factor”—that could represent a person’s general tendency towards distraction and may be linked with attention-deficit/hyperactivity disorder (ADHD). Han Zhang of the University of Michigan, Ann Arbor, and colleagues present these findings in the open-access journal PLOS ONE on October 25, 2023. Prior research has explored various types of distraction, such as external stimulations, repetitive ...

A new study explores themes in Twitter discussions of deepfake videos related to the Russian invasion of Ukraine, highlighting the potential for real videos to be mistaken for deepfakes and for deepfakes to fuel conspiracy theories. John Twomey of University College Cork, Ireland, and colleagues present these findings in the open-access journal PLOS ONE on October 25, 2023. Created using artificial intelligence, deepfake videos typically feature a person saying and doing things they never actually did in real life. Deepfake technology has advanced considerably, sparking concerns about its potential harms. ...

Ancient people immigrated to Cancun Island and were treated just like locals, according to a study published October 25, 2023 in the open-access journal PLOS ONE by Andrea Cucina of the Autonomous University of Yucatan, Mexico and colleagues. The Late Postclassic (AD 1200-1500) in the northern Maya lowlands was a period of major changes, including the development of many settlements along the east coast of the Yucatan Peninsula, influenced in part by expanded trade routes. Previous research has found that these settlements were home to many non-local individuals, but it remains unclear whether these people were treated as “foreigners” ...

Human populations in Neolithic Europe fluctuated with changing climates, according to a study published October 25, 2023 in the open-access journal PLOS ONE by Ralph Großmann of Kiel University, Germany and colleagues. The archaeological record is a valuable resource for exploring the relationship between humans and the environment, particularly how each is affected by the other. In this study, researchers examined Central European regions rich in archaeological remains and geologic sources of climate data, using these resources to identify correlations between human population trends and climate change. The ...

A first ever study of wartime deepfake videos reveals their impact on news media and outlines implications for social media companies, media organisations and governments.   Deepfakes are artificially manipulated audio-visual material. Most deepfake videos involve the production of a fake ‘face’ constructed by Artificial Intelligence, that is merged with an authentic video, in order to create a video of an event that never really took place. Although fake, they can look convincing and are often produced to imitate or mimic an individual.  Researchers at University ...

A new research study shows that cerebrospinal fluid reduces current treatment efficacy in brain cancer and identifies new therapeutic opportunities. Cerebrospinal fluid, the clear colourless liquid that protects the brain, also may be a factor that makes brain cancers resistant to treatment, Australian researchers led by Associate Professor Cedric Bardy at the South Austraila Health and Medical Research Institute (SAHMRI) and Flinders University reveal in the journal Science Advances. Reporting how this occurs, the study in high-profile journal Science Advances shows that a decades-old anti-anxiety drug can improve the effectiveness of chemo-radiotherapy ...

Pair-bonded Java sparrows show enlarged eye rings to signal breeding readiness. Birds are known for their elaborate courtship rituals and romantic gestures that are replete with beautiful songs, complex dances, gift-giving practices, preening, and flamboyant plumage. While changes in colorful external attributes during this period has attracted much attention, the role of facial features remains an under-investigated aspect of this behavior.  Associate Professor Masayo Soma and her research group at the Graduate School of Science, Hokkaido University, reported increased swelling in Java sparrows’ eye rings—an area of blushed bare skin around the eyes—upon ...

Atrial fibrillation (AF) diagnosis was associated with a 45% increased risk of mild cognitive impairment (MCI) among a cohort of 4.3 million individuals in the UK, according to a new study published in JACC: Advances. These findings suggest that cardiovascular risk factors and multiple comorbidities could further the progression from MCI to dementia in this cohort. MCI is an early stage of cognitive function decline. In some cases it can be reversed, but it can indicate development of early dementia-associated disease. There has not been sufficient research on the development of MCI in AF patients and the subsequent development of dementia, so the authors of this study sought to ...

Flexible three-dimensional (3D) displays drive innovation in the next-generation display technology, as they allow for the creation of versatile and adaptable displays that can be easily manipulated and customized to fit various viewing scenarios.   Printing circularly polarized luminescence (CPL, generated by the intrinsic chirality of luminescent materials) materials on moving, deformable and free-form surfaces serves to fabricate large-scale and high-performance integral imaging 3D displays: CPL provides a helping hand using its unusual optical rotation characteristics to achieve considerable contrast ratio and wide viewing angle.   Scientists led by Professor ...

Zika virus infection in pregnant rhesus macaques slows fetal growth and affects how infants and mothers interact in the first month of life, according to a new study from researchers at the California National Primate Research Center at the University of California, Davis. The work, published Oct. 25 in Science Translational Medicine, has implications for both humans exposed to Zika virus and for other viruses that can cross the placenta, including SARS-CoV2, responsible for the COVID-19 pandemic. “Initially I thought this was a story about Zika, but as I looked at the results I think this is also a story about ...

Scientists have long known that chloroplasts help plants turn the sun’s energy into food, but a new study, led by plant biologists at the University of California, Davis, shows that they are also essential for plant immunity to viral and bacterial pathogens. Chloroplasts are generally spherical, but a small percentage of them change their shape and send out tube-like projections called “stromules.” First observed over a century ago, the biological function of stromules has remained ...

For four years, NASA’s InSight lander recorded tremors on Mars with its seismometer. Researchers at ETH Zurich collected and analysed the data transmitted to Earth to determine the planet’s internal structure. “Although the mission ended in December 2022, we’ve now discovered something very interesting,” says Amir Khan, a Senior Scientist in the Department of Earth Sciences at ETH Zurich. An analysis of recorded marsquakes, combined with computer simulations, paint ...

LAWRENCE — For the past 50 years, standardized tests have been the norm in American schools, a method proponents say determines which schools are not performing and helps hold educators accountable. Yet for the past 20 years, it has become clear that testing has failed to improve education or hold many accountable, according to a University of Kansas researcher whose new book details its history. “An Age of Accountability: How Standardized Testing Came to Dominate American Schools and Compromise Education” by John Rury, professor emeritus of educational leadership & policy studies at KU, tells the story of how testing became ...

During the summer of 2022, the Indus River in Pakistan overflowed its banks and swept through the homes of between 30-40 million people. Eight million were permanently displaced, and at least 1,700 people died. Damages to crops, infrastructure, industry, and livelihoods were estimated at $30 billion. In response to this, Stanford researchers from the Natural Capital Project (NatCap) and the Carnegie Institution for Science collaborated on a new way to quickly calculate the approximate depths of ...

Rutgers researchers have used neuroimaging to demonstrate that cocaine addiction alters the brain’s system for evaluating how rewarding various outcomes associated with our decisions will feel. This dampens an error signal that guides learning and adaptive behavior. The observed changes likely propagate a mysterious aspect of some addictive behavior—the tendency to keep doing harmful things that sometimes have no immediate benefit. Those changes also make it harder for long-term users of cocaine to correctly estimate how much benefit they’ll derive from other available actions. Experts have long hypothesized that cocaine and other addictive ...

A new study by UC Davis Health endocrinology researchers has shown a high prevalence of thyroid cancer among transgender female veterans. It’s the first evidence of such a disparity in the transgender female population in the United States. The researchers presented their findings this month at the American Thyroid Association Annual Meeting. The study was prompted by what the doctors noticed while caring for patients. “As a group of physicians, we observed anecdotally through clinical observation that among 50 transgender women in our clinic, two were diagnosed with thyroid ...

FOR IMMEDIATE RELEASE In a mouse study designed to explore the impact of marijuana’s major psychoactive compound, THC, on teenage brains, Johns Hopkins Medicine researchers say they found changes to the structure of microglia, which are specialized brain immune cells, that may worsen a genetic predisposition to schizophrenia. The findings, published Oct. 25 in Nature Communications, add to growing evidence of risk to brain development in adolescents who smoke or eat marijuana products. “Recreational ...

A team of scientists has used multiple space and ground-based telescopes, including NASA’s James Webb Space Telescope, NASA’s Fermi Gamma-ray Space Telescope, and NASA’s Neil Gehrels Swift Observatory, to observe an exceptionally bright gamma-ray burst, GRB 230307A, and identify the neutron star merger that generated an explosion that created the burst. Webb also helped scientists detect the chemical element tellurium in the explosion’s aftermath. Other elements near tellurium on the periodic table – like iodine, which is needed ...
