Scientists studying ancient ocean fossils found that the Arabian Sea was better oxygenated 16 million years ago, even though the planet was warmer than today. Oxygen levels only plunged millions of years later, after the climate cooled, defying ...
Small mammals are early warning systems for environmental damage, but many species look almost identical, making them hard to track. Scientists have developed a new footprint-based method that can tell apart nearly indistinguishable species with ...
Scientists have created a device that captures carbon dioxide and transforms it into a useful chemical in a single step. The new electrode works with realistic exhaust gases rather than requiring purified CO2. It converts the captured gas into formic ...
What looked like a pearl necklace on a tiny spider turned out to be parasitic mite larvae. Scientists identified the mites as a new species, marking the first record of its family in Brazil. The larvae attach to juvenile spiders and feed on lymph ...
The Ediacara Biota are some of the strangest fossils ever found--soft-bodied organisms preserved in remarkable detail where preservation shouldn't be possible. Scientists now think their survival in sandstone came from unusual ancient seawater ...
Scientists have found compelling new evidence that humans, not glaciers, brought Stonehenge's bluestones to the site. Using advanced mineral analysis, researchers searched nearby river sediments for signs glaciers once passed through the area--and .. ...
Our genome isn't as peaceful as it looks--some DNA elements are constantly trying to disrupt it. Scientists studying fruit flies discovered that key proteins protecting chromosome ends must evolve rapidly to counter these internal threats. When these ...
A 5,500-year-old skeleton from Colombia has revealed the oldest known genome of the bacterium linked to syphilis and related diseases. The ancient strain doesn't fit neatly into modern categories, hinting at a forgotten form that split off early in . ...
A Roman-era skeleton discovered in southern England has finally given up her secrets after more than a decade of debate. Known as the Beachy Head Woman, she was once thought to have roots in sub-Saharan Africa or the Mediterranean--an idea that ...
Long before farming took hold, ancient Indigenous peoples of the American Southwest were already shaping the future of a wild potato. New evidence shows that this small, hardy plant was deliberately carried across the Four Corners region more than 10 ...
