MINNEAPOLIS — A new study found that Native Hawaiian or Pacific Islander people had the highest rate of stroke among people from other race and ethnic groups, with a rate more than three times higher than that of white people. The study is published on August 27, 2025, in Neurology®, the medical journal of the American Academy of Neurology. “Multiple studies have shown racial and ethnic disparities in the rate of stroke in the United States, but there is little information on the rate among Native Hawaiian or Pacific Islander people, especially ...

The textbook picture of how planets form – serene, flat discs of cosmic dust – has just received a significant cosmic twist. New research, published in the Astrophysical Journal Letters, is set to reshape this long-held view. An international team of scientists, wielding the formidable power of the Atacama Large Millimetre/submillimetre Array (ALMA), has found compelling evidence that many protoplanetary discs, the very birthplaces of planets, are in fact subtly warped.   These slight bends and twists in the disc plane, often just a few ...

Humans could learn a thing or two from orangutans when it comes to maintaining a balanced, protein-filled diet. Great apes native to the rainforests of Indonesia and Malaysia, orangutans are marvels of adaptation to the vagaries of food supply in the wild, according to an international team of researchers led by a Rutgers University-New Brunswick scientist. The critically endangered primates outshine modern humans in avoiding obesity through their balanced choices of food and exercise, the scientists found. The researchers reported their findings, based on 15 years of firsthand observations of wild orangutans ...

Insomnia patients taking cannabis-based medical products reported better quality sleep after up to 18 months of treatment, according to a study published August 27 in the open-access journal PLOS Mental Health by Arushika Aggarwal from Imperial College London, U.K., and colleagues. About one out of every three people has some trouble getting a good night’s rest, and 10 percent of adults meet the criteria for an insomnia disorder. But current treatments can be difficult to obtain, and the drugs approved for insomnia run the risk ...

Intrusive distracting thoughts may be associated with anxiety and linked to lower well-being, and occur more often when alone than in company, per experience of sampling survey of students.    Article URL: https://plos.io/4lBYjWu Article Title: Patterns of ongoing thought in the real world and their links to mental health and well-being Author Countries: Canada, England, United States Funding: This research was supported by (i) a National Science and Engineering Research Council (NSERC) graduate fellowship (author: BM), (ii) an award from the Government of Canada’s New Frontiers in Research Fund (grant ID: NFRF-2021-00183, ...

A newly-discovered species of a large, crocodile-relative predator has been described via a remarkably well-preserved fossil from Argentina, according to a study published August 27, 2025, in the open-access journal PLOS One by Fernando Novas from Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”, Argentina, and colleagues. The Chorrillo Formation formed around 70 million years ago, during the Maastrichtian age at the very end of the Cretaceous period. At this time, southern Patagonia was a warm, seasonally humid landscape of freshwater floodplains, home to creatures like dinosaurs, turtles, frogs, and various mammals. The new fossil unearthed in this formation is ...

A new survey-based study suggests that the “unhappiness hump”—a widely documented rise in worry, stress, and depression with age that peaks in midlife and then declines—may have disappeared, perhaps due to declining mental health among younger people. David Blanchflower of Dartmouth College, U.S., and colleagues present these findings in the open-access journal PLOS One on August 27, 2025. Since 2008, a U-shaped trend in wellbeing with age, in which wellbeing tends to decline from childhood until around age 50 before ...

Breathwork while listening to music may induce a blissful state in practitioners, accompanied by changes in blood flow to emotion-processing brain regions, according to a study published August 27, 2025, in the open-access journal PLOS One by Amy Amla Kartar from the Colasanti Lab in the Department of Clinical Neuroscience at Brighton and Sussex Medical School, U.K., and colleagues. These changes occur even while the body’s stress response may be activated and are associated with reporting reduced negative ...

NEW YORK, August 27, 2025 — Researchers at the Nanoscience Initiative at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have made a breakthrough in the fight against viral diseases. Their study, published in the journal Science Advances, offers a promising path toward the development of the world’s first broad-spectrum antiviral (BSA), which could be deployed against a wide range of deadly viruses, including future pandemic threats. Unlike bacterial infections, which doctors often begin immediately treating with broad-spectrum antibiotics while they work to determine the specific bacteria, viral infections ...

A new study of young adults has strongly linked better sleep quality with better mental wellbeing, with fruit and vegetable consumption and physical activity also strongly associated with psychological wellbeing. Perhaps surprisingly, the findings also suggest that boosting fruit and vegetable intake could potentially help mitigate the effects on wellbeing of a poor night’s sleep. Dr. Jack Cooper, previously from the University of Otago, New Zealand, and colleagues present these findings in the open-access journal PLOS One on August 27, 2025. Prior research ...

A new study from researchers at Baylor College of Medicine brings hope for a more personalized approach to treat estrogen receptor-positive (ER+) breast cancer, the most common type of this cancer. The team identified a biomarker in preclinical ER+ breast cancer models that indicates that the tumor is more likely to respond to treatment with CDK4/6 inhibitors. The findings support further clinical studies to determine whether this marker may help identify patients who could benefit from CDK4/6 inhibitors. The study appeared in Science Translational Medicine. ER+ breast ...

Researchers at Stockholm University have succeeded in creating a molecular blueprint of how one of the world's most dangerous toxins, botulinum toxin, is structured, stabilised, delivered and released. The research, published in the scientific journal Science Advances, paves the way for more effective drugs. Botulinum toxin is the strongest poison known to man – a million times more toxic than that found in cobra venom. The toxin is produced by the bacterium Clostridium botulinum. The toxin causes the serious illness botulism. However, the toxin also has many medical uses, for treating chronic migraine, ...

Philadelphia, August 27, 2025 – Researchers at Children’s Hospital of Philadelphia (CHOP) found that certain lipids, or fats, in obesity-causing foods also cause asthma-like lung inflammation. The findings suggest that in addition to modifying dietary choices, certain existing drugs could be repurposed to help treat this type of asthma. The findings were published online today by the journal Science Translational Medicine. The study was prompted by researchers noticing an association between childhood obesity and neutrophilic asthma, a non-allergic type of asthma triggered ...

Supercell thunderstorms are among the most impactful weather events in Europe. They typically occur in summer and are characterized by a rotating updraft of warm, humid air that brings strong winds, large hail and heavy rain. The impact is significant and often leads to property damage, agricultural losses, traffic chaos and even threats to human safety. The collaboration between the Institute of Geography, the Oeschger Center for Climate Change Research and the Mobiliar Lab for Natural Risks at the University of Bern and the Institute for Atmospheric and Climate ...

SAN FRANCISCO—Certain brain cells are responsible for coordinating smooth, controlled movements of the body. But when those cells are constantly overactivated for weeks on end, they degenerate and ultimately die. This new observation made by scientists at Gladstone Institutes may help explain what goes awry in the brains of people with Parkinson’s disease. Researchers have long known that a particular subset of neurons die as Parkinson’s disease progresses, but they aren’t sure why. The new work, published in the scientific journal eLife, shows that in mice, chronic activation of these neurons can directly cause their demise. The scientists hypothesize ...

Bariatric surgery is usually effective on its own for weight loss, but an increasing proportion of patients who undergo bariatric surgery start taking one of the new glucagon-like 1 peptide receptor agonist (GLP-1) weight-loss drugs in the years after their surgery, according to a new study led by researchers at the Johns Hopkins Bloomberg School of Public Health. The researchers analyzed de-identified national electronic health records covering 112,858 individuals who underwent bariatric surgery from January 2015 to May 2023. They found that 14% of those patients used a GLP-1 such ...

Pelvic organ prolapse (POP) is a disorder that primarily affects older women who have experienced multiple vaginal childbirths.  Repeated vaginal deliveries can cause the muscles and connective tissue that hold the pelvic organs—the vagina, bladder, uterus, urethra, and rectum—to weaken, causing one or more of the organs to drop out of position and bulge or extrude outside the body.  “There’s a breakdown and loss of the elastic matrix which contributes to tissue elasticity, similar to how a rubber band can stretch and recoil,” says Lehigh University ...

We have all been familiar since childhood with the fact that our left and right hands are identical in structure but not in shape. They are mirror images of each other. In everyday life, this means that a left-handed glove does not fit on the right hand. This “handedness” is also a fundamental property of matter: similar to our hands, many molecules exist in two mirror-image versions, which, despite looking confusingly similar, are actually not identical. Chemists call this chirality. The distinction between right- and left-handed chiral molecules ...

(MEMPHIS, Tenn. – August 27, 2025) A study looking at the biophysical properties of an abnormal protein driving cancer cells is giving scientists new therapeutic clues for how to treat ependymoma, the third most common childhood brain tumor. St. Jude Children’s Research Hospital scientists were studying how the fusion protein ZFTA–RELA, implicated in 95% of ependymomas in the brain cortex, drives disease. Results of the study demonstrate that disordered regions of the fusion protein cause the formation of droplets within cells called condensates. The researchers revealed that these “membraneless organelles” are essential for ependymoma ...

"Thus, our studies revealed regulatory mechanisms of glycolysis-driven cellular senescence by AUF1-mediated decay of PGAM1 and PDP2 mRNAs.” BUFFALO, NY — August 27, 2025 — A new research paper was published in Volume 17, Issue 7 of Aging (Aging-US) on July 24, 2025, titled “RNA-binding protein AUF1 suppresses cellular senescence and glycolysis by targeting PDP2 and PGAM1 mRNAs.” In this study, Hyejin Mun, Chang Hoon Shin, Mercy Kim, Jeong Ho Chang, and Je-Hyun Yoon from the University of Oklahoma and Kyungpook National University investigated how changes in cellular metabolism contribute to aging. ...

What do the rumblings of Iceland’s volcanoes have in common with the now peaceful volcanic islands off Scotland’s western coast and the spectacular basalt columns of the Giant’s Causeway in Northern Ireland? About sixty million years ago, the Icelandic mantle plume—a fountain of hot rock that rises from Earth’s core-mantle boundary—unleashed volcanic activity across a vast area of the North Atlantic, extending from Scotland and Ireland to Greenland. For decades, scientists have puzzled over why this burst of volcanism was so extensive. Now, research led by the University of Cambridge ...

When faced with advanced cancer, many patients must make deeply personal decisions about their care plan. Some may pursue more aggressive treatment with the primary aim of extending life, while others may wish to prioritize comfort and quality of life.  But according to a new study led by researchers at the UCLA Health Jonsson Comprehensive Cancer Center and the UCLA Palliative Care Research Center, many people with advanced cancer report that their treatment does not align with their personal care goals. The findings, published in the journal Cancer, reveal that 37% of patients with advanced ...
