GLP-1 drugs like Ozempic have transformed weight loss in the U.S., with nearly 12% of Americans having tried them, according to a new RAND report. Usage is especially high among women aged 50 to 64, while men catch up in older groups. Despite ...

Scientists in Korea have engineered magnetic nanohelices that can control electron spin with extraordinary precision at room temperature. By combining structural chirality and magnetism, these nanoscale helices can filter spins without complex ...

Researchers at UBC have found a way to mimic the elusive Schwinger effect using superfluid helium, where vortex pairs appear out of thin films instead of electron-positron pairs in a vacuum. Their work not only offers a cosmic laboratory for ...

Billions of years ago, Mars may not have been the frozen desert we see today. New simulations suggest that volcanic eruptions pumped out reactive sulfur gases, creating greenhouse effects strong enough to trap warmth and possibly liquid water. This . ...

Astronomers using the James Webb Space Telescope have uncovered mysterious "little red dots" that may not be galaxies at all, but a whole new type of object: black hole stars. These fiery spheres, powered by ravenous black holes at their core, could ...

Chronic insomnia may do more than leave you groggy, it could speed up brain aging. A large Mayo Clinic study found that people with long-term sleep troubles were 40% more likely to develop dementia or cognitive impairment, with brain scans showing .. ...

Researchers trained AI on tens of thousands of eye scans, enabling doctors to predict which keratoconus patients need early treatment and which can be safely monitored, cutting down on unnecessary procedures while preventing vision loss.

A massive Danish study reveals that despite the remarkable weight-loss benefits of semaglutide, more than half of adults without diabetes stop using it within a year. High costs, unpleasant side effects, and underlying medical or psychiatric ...

Not all barnacles just sit on rocks and ships. Some invade crabs, growing like a parasitic root system that hijacks their bodies. A mysterious group called y-larvae has baffled scientists for over a century, with no known adult stage. Genetic ...

Scientists have uncovered that "forever chemicals" like PFAS are even more acidic than anyone realized, meaning they dissolve and spread in water with alarming ease. Using a cutting-edge method combining NMR spectroscopy and computer modeling, ...
