Supplements are often marketed as shortcuts to better health, but for many older adults, the real issue is whether they have a specific deficiency. Vitamins like B12 and D can play an important role when levels are low, while protein may be one of .. ...

Scientists warn that free-living amoebae may be an underappreciated public health threat, capable of causing deadly infections and shielding other dangerous microbes from water treatment. Climate change and aging infrastructure could help these ...

A team at the University of Minnesota discovered that changing a metal film's thickness by just a few nanometers can dramatically alter how it behaves electronically. The finding reveals a surprising new way to control metals and could help power ...

NASA's PExT terminal has shown that spacecraft can seamlessly communicate through multiple government and commercial networks, a major step beyond traditional single-network systems. The mission is now expanding to test new capabilities that could .. ...

Scientists have successfully tested an AI-designed universal coronavirus vaccine in humans for the first time, finding it to be safe and well tolerated. The vaccine generated immune responses against multiple coronaviruses, including SARS-CoV-2, SARS ...

Scientists have identified genetic variants that may make some people less responsive to GLP-1 drugs used to treat Type 2 diabetes. Roughly 10% of the population carries these variants, which appear to cause a mysterious form of "GLP-1 resistance." . ...

Octopuses may be even smarter than we thought. Researchers at Dartmouth found that octopuses can learn to use mirrors to locate food hidden behind them--a skill previously seen only in vertebrates like mammals and birds. After training, the animals . ...

Scientists have proposed a new method for finding tightly bound supermassive black hole pairs by searching for stars that flash repeatedly as their light is magnified by the black holes' gravity. The timing and brightness of these bursts could ...

Scientists have uncovered a surprising force that may help explain how binary star systems form so quickly. New supercomputer simulations show that magnetic fields surrounding newborn stars can act like a cosmic brake, stripping away angular momentum ...

Scientists have uncovered unexpected quantum complexity inside cobalt, a metal long thought to be fully understood. Advanced measurements revealed a dense network of topological electronic states that remain robust at room temperature. These states . ...
