Phys.org / Researchers uncover gut-liver serotonin pathway that limits nanoparticle and viral delivery
A new study has for the first time elucidated the gut-liver immune regulatory axis jointly maintained by intestinal commensal bacteria and the intestinal endocrine system, and uncovered the fundamental mechanism underlying ...
Medical Xpress / FDA approves higher-dose Wegovy to help people lose more weight
A stronger version of the popular weight loss drug Wegovy is on the way after federal regulators signed off on a higher dose. The U.S. Food and Drug Administration (FDA) approved a 7.2-milligram dose of Novo Nordisk's semaglutide, ...
Medical Xpress / Initial tests find lead in children's fast-fashion clothing
Fast fashion is an inexpensive way to dress rapidly growing kids. But preliminary research has found that the fabric in some of these items contains an unwanted, toxic ingredient: lead. After testing several shirts from different ...
Medical Xpress / Guidance issued for conservative management of patients with kidney failure
Conservative management of people with kidney failure throughout the chronic kidney disease (CKD) trajectory is discussed in an article and executive summary published online Jan. 9 in the Journal of the American Society ...
Phys.org / Clearest evidence yet that giant planets spin faster than their cosmic lookalikes
For decades, astronomers have struggled to differentiate giant planets from brown dwarfs, a class of objects more massive than planets but too small to ignite nuclear fusion like true stars. Through a telescope, these cosmic ...
Phys.org / DESI maps C-19, an extremely metal-poor Milky Way stellar stream
Using the Mayall 4-meter telescope at Kitt Peak National Observatory, an international team of astronomers has observed C-19—an extremely metal-poor stellar stream in the Milky Way's halo. Results of the observational campaign, ...
Phys.org / How conversation works—and why people with hearing loss rely more on their powers of prediction
"Ultimately, the bond of all companionship, whether in marriage or friendship, is conversation," wrote Oscar Wilde.
Phys.org / Two-thirds of workers are burned out—here's what science says about how to tackle it
Burnout is at an all-time high, with some studies saying two-thirds of employees now cite job burnout as a major challenge. Overwork and chronic stress do not just drain energy, they can erode health, contributing to a wide ...
Medical Xpress / Study identifies liver–metabolic disease as a key risk factor for heart failure in older adults with atrial fibrillation
Atrial fibrillation (AFib) is the most common cardiac arrhythmia worldwide and a major contributor to heart failure (HF), affecting over 64 million people globally. Steatotic liver disease (SLD) encompasses a spectrum of ...
Phys.org / Physicists find electronic agents that govern flat band quantum materials
Physicists have directly visualized the fundamental electronic building blocks of flat-band quantum materials, a class of systems in which electron motion is effectively quenched and strong interactions give rise to emergent ...
Phys.org / The deep freshwater reservoir hidden beneath the Great Salt Lake
A potentially huge underground reservoir of freshwater beneath the Great Salt Lake is coming into sharper focus with a new study that used airborne electromagnetic (AEM) surveys to X-ray geologic structures under Farmington ...
Phys.org / Earth's toughest microbes could help save the planet and find life on other worlds
Extremophiles may well be tiny, but they are making a huge contribution to the health of our planet and our lives. A new review of these microorganisms, published in the journal Frontiers in Microbiology, explains how they ...
