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 ...
Scientists have discovered that the aging human brain may be far less isolated from the rest of the body than once believed. Stanford researchers found that large numbers of immune cells from the blood begin entering the brain as early as middle age, ...
Nuclear reactors may go dark, but their fuel continues producing a faint antineutrino "glow" long after shutdown. Researchers have now detected that residual signal for the first time, finding it closely matched predictions of radioactive decay ...
A tiny superconducting engine has successfully converted heat near absolute zero into useful work, demonstrating the first cyclic quantum heat engine of its kind. Future versions could operate autonomously inside quantum computers, potentially ...
A surprising stress-related signal may help the brain repair itself after injury. Researchers found that myelin-producing precursor cells rapidly release the stress hormone CRH near damaged brain tissue, helping control how those cells mature and ...
Women who used estrogen-only hormone therapy later in life were less likely to develop dementia and showed fewer signs of Alzheimer's disease in their brains, according to a large study of more than 21,000 participants. Hormone therapy use was linked ...
