Scientists have found that a famous 2-billion-year-old chemical signature, once thought to record a massive global change in Earth's carbon cycle, may instead have been produced by local magma, hydrocarbons, and methane-eating microbes. The discovery ...

Scientists discovered that tiny amounts of lead in ancient ink can make writing inside burned papyrus scrolls stand out dramatically in X-ray scans. The technique could help unlock lost Greek and Roman texts preserved by the eruption of Mount ...

Scientists recreated a particle-forming process linked to the extreme physics of the early universe using a 13-ion quantum simulator. The breakthrough suggests quantum computers could eventually help researchers investigate how matter formed and ...

Artemis II astronauts Victor Glover and Reid Wiseman are transitioning to emeritus status at NASA after their historic journey around the Moon earlier this year. The pair will continue advising and mentoring NASA teams as preparations accelerate for ...

Tirzepatide, sold as Mounjaro and Zepbound, activated calorie-burning brown fat in obese mice, revealing a potential metabolic effect beyond appetite suppression. If confirmed in humans, the finding could help explain the drug's powerful benefits and ...

Scientists discovered a surprising energy paradox in the brain during REM sleep, the stage most closely associated with dreaming. Blood supply to the brain begins increasing even before REM starts, but neurons' immediately available energy, measured ...

Scientists think beneficial fungi could help transform nutrient-poor lunar and Martian regolith into a material capable of supporting crops. By helping plants access nutrients and withstand harsh conditions, these microbes could someday make self ...

Scientists discovered rare flavoalkaloids in Cannabis leaves for the first time, along with dozens of other phenolic compounds that had never been reported in the plant. The findings suggest that Cannabis leaves, often discarded as waste, may contain ...

Scientists discovered two strange new sea spider species in the Salish Sea, including a hairy-legged, red-eyed species that can groom itself with comb-like appendages. Another is frequently covered in tiny parasites, and researchers say many more ...

A major analysis suggests Phelan-McDermid syndrome, a genetic disorder closely linked to autism, may affect about 1 in 7,300 people and more than 45,000 Americans. Researchers warn that thousands of cases may remain hidden because genetic testing is ...
