Exercise and healthy blood sugar levels in midlife may help slow cognitive decline decades later. Physical activity appeared especially beneficial for Mexican American adults, suggesting that some brain-protective factors may differ across ...
Physicists may have uncovered a hidden feature inside protons that helps preserve one of matter's most fundamental properties. RHIC collision data suggest baryon number is carried not simply by three quarks, but by a Y-shaped junction of the gluons . ...
As we age, the body appears to sacrifice walking efficiency in exchange for stability. Older adults stiffen the ankle more with each step, which may help prevent falls but also forces the muscles to work harder while producing less forward motion. .. ...
Scientists have discovered a new extinct amphibian species hiding in the fossil collections of Los Angeles' La Brea Tar Pits. Named Spea labreae, the Ice Age spadefoot toad is an exceptionally rare find--only one other extinct Pleistocene amphibian . ...
Astronomers have witnessed a black hole violently shredding a massive star, creating one of the most energetic stellar explosions ever observed. The event, nicknamed "the Whippet," briefly released about 400 billion times the Sun's energy and sent a ...
COVID-19 can reactivate dormant viruses hiding in the body, including Epstein-Barr, cytomegalovirus, and several herpes viruses. One poorly understood viral family was strongly associated with long COVID and lasting disability, offering a potentially ...
Fossils collected in Osaka more than 30 years ago have revealed a surprise hiding in plain sight: four previously unrecognized bones from a giant Cretaceous mosasaur. Among them is the first confirmed premaxilla--the frontmost bone of the upper jaw- ...
A widely available food-preservation chemical is emerging as a disturbing factor in rising UK suicide deaths, particularly among younger people and men. Researchers say the scale may be underestimated and are calling for urgent restrictions on access ...
Scientists have long thought an unusual genetic system helped ants, bees, and wasps evolve their extraordinary social colonies. A massive new analysis suggests that genetics alone can't explain it--and the real secret may lie in other traits unique . ...
Scientists have uncovered why two seemingly opposite ways of targeting the same brain receptor can both promote weight loss. In mice, activating the GIP receptor in the brainstem reduced appetite, while blocking it in the hypothalamus removed a kind ...
