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 ...
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 discovery pushes key evolutionary milestones back by up ...
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 possible new target for understanding why people ...
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 for burrowing, while another ancient snake was ...
A massive crocodilian capable of attacking dinosaurs has been brought back to life as the first scientifically accurate mounted skeleton of Deinosuchus schwimmeri. The 31-foot replica at Georgia’s Tellus Science Museum was built from detailed ...
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 vibrations recorded by dozens of seismic sensors. It ...
Stanford researchers discovered immune cells in flatworms that explode within minutes, killing nearby bacteria and foreign cells before vanishing completely. Their unusually fast and localized attack ...
August brings four major celestial events, including a solar eclipse and the peak of the Perseid meteor shower. Dark New Moon skies could make the Perseids especially impressive, while Venus will blaze in the west after sunset. A deep partial lunar ...
Fossilized dinosaur bones from Wyoming are offering a rare glimpse into the feeding behavior of Tyrannosaurus rex. Researchers examined more than 3,000 bones dating back 72 to 66 million years and found just 12 with possible tooth traces, including ...
Scientists have uncovered a surprising way that “jumping genes” may move between species and speed up evolution. While these mobile genetic elements were thought to travel mainly inside viruses or plasmids, researchers found circular intron RNA ...
A specially engineered chewing gum reduced HPV by up to 93% and nearly eliminated two bacteria linked to head and neck cancer. The treatment preserved beneficial mouth bacteria, raising hopes for a safer and more affordable ...
A tiny 518-million-year-old sea creature has revealed the earliest known evidence of the structures that eventually became spiders’ fangs. Hidden inside the fossil were pincerlike limbs and preserved soft tissues that help explain how the ...
