A massive study of over 4 million adults has revealed that cannabis use may nearly quadruple the risk of developing diabetes. Despite some earlier suggestions that cannabis might have metabolic benefits, this large analysis found significantly higher ...

By analyzing tooth enamel chemistry, scientists uncovered proof that Jurassic dinosaurs divided up their meals in surprising ways--some choosing buds and leaves, others woody bark, and still others a mixed menu. This dietary diversity helped massive ...

Sweetpotato, a critical food crop for millions, has finally had its genetic code fully decoded after decades of mystery. Scientists unraveled its extraordinarily complex genome of six chromosome sets, revealing a hybrid origin stitched together from ...

Billions of years ago, Mars may not have been the frozen desert we see today. New simulations suggest that volcanic eruptions pumped out reactive sulfur gases, creating greenhouse effects strong enough to trap warmth and possibly liquid water. This . ...

Not all barnacles just sit on rocks and ships. Some invade crabs, growing like a parasitic root system that hijacks their bodies. A mysterious group called y-larvae has baffled scientists for over a century, with no known adult stage. Genetic ...

Octopuses aren't just flexible--they're astonishingly strategic. A new study reveals how their eight arms coordinate with surprising precision: front arms for exploring, back arms for locomotion, and every arm capable of twisting, bending, shortening ...

Scientists in Tokyo have uncovered "Inocles," massive strands of extrachromosomal DNA hidden inside bacteria in human mouths. These giants, overlooked by traditional sequencing, could explain how oral microbes adapt, survive, and impact health. Found ...

Mars' Jezero Crater holds signs of ancient water and strange mineral reactions, some linked with organic compounds. With Perseverance's samples and AI-refined mineral maps, scientists are closing in on whether Mars once had the chemistry needed for . ...

Forever chemicals known as PFAS have turned up in an unexpected place: beer. Researchers tested 23 different beers from across the U.S. and found that 95% contained PFAS, with the highest concentrations showing up in regions with known water ...

Hidden within Arctic ice, diatoms are proving to be anything but dormant. New Stanford research shows these glass-walled algae glide through frozen channels at record-breaking subzero temperatures, powered by mucus-like ropes and molecular motors. .. ...
