A long-term brain study found that common risks such as smoking, high blood pressure, heart disease, and high blood lipids were strongly linked to damage associated with vascular dementia. The finding...
Genetic changes may set off a chain reaction that causes the spine’s natural shock absorbers to harden and deteriorate. Zebrafish with a faulty collagen-related gene developed mineral buildup and spin...
Millions of sperm do not always compete alone—some species send them into action as coordinated teams. A sweeping evolutionary study found that this cooperation is widespread among arthropods and has ...
Ancient seafloor sediments have revealed a surprising twist in how the Atlantic’s massive circulation system works. During a cold period about 3.4 million years ago, the flow of warm, salty water from...
Tiny pollution particles from smoke, soot, and dust may worsen rheumatoid arthritis and raise the risk of painful flares, particularly after prolonged exposure. The findings suggest that avoiding poor...
A prescription form of THC helped many people with PTSD escape recurring trauma-related nightmares, with more than one-third reporting that the nightmares disappeared completely after ten weeks. The r...
A mathematician working at Anthropic says he used the AI model Claude Fable 5 to uncover a remarkably simple counterexample to the Jacobian conjecture, a famous problem that has resisted mathematician...
A spectacular fossil site in Canada contains 567-million-year-old creatures that may represent some of the earliest animals to move, reproduce sexually, and develop recognizable body plans. The discov...
A simple change in posture may subtly affect how people feel and make decisions. Participants who sat upright reported greater feelings of pride and took more successful risks in a virtual balloon gam...
A group of brain cells called orexin neurons appears to help us keep working when reaching a reward becomes increasingly difficult. Blocking their activity weakened motivation in rats, pointing to a p...
An exceptionally preserved snake fossil from Brazil reveals that early snakes were far more diverse than scientists once thought. Detailed brain reconstructions show that Tametara mirim was adapted fo...
A massive magma reservoir has been detected deep beneath Tuscany, despite showing no obvious signs at the surface. Scientists mapped the roughly 6,000-cubic-kilometer body using natural ground vibrati...
