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 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 ...

Scientists have captured a subduction zone off Vancouver Island in the process of tearing itself apart, revealing that these massive tectonic systems may die piece by piece rather than all at once. The discovery could help explain ancient plate ...

A magnet-producing bacterium extended the average lifespan of C. elegans worms by more than 43% while helping protect their neurological and intestinal health. Researchers traced much of the effect to suppression of ferroptosis, a damaging form of .. ...

Scientists discovered two tiny new snail species in Montenegro, showing that even Europe still holds animals unknown to science. One lives in the threatened Komarnica Canyon, where a proposed hydropower reservoir could destroy habitat before its full ...

A broken rib from Scotty, the largest known T. rex skeleton, contains an extraordinary fossilized network of blood vessels formed while the dinosaur was healing. Scientists used neutron and X-ray imaging to look inside the 66-million-year-old bone .. ...

The Cascadia subduction zone and northern San Andreas fault may sometimes rupture in rapid succession, according to evidence preserved in 3,100 years of ocean sediments. Researchers identified unusual sediment layers suggesting that earthquakes on .. ...
