Researchers in Japan traced a hidden medieval solar storm using ancient tree rings and centuries-old sky observations. The team linked reports of eerie red auroras with spikes of carbon-14 trapped in buried wood, revealing a powerful solar radiation ...

Scientists analyzing the genomes of thousands of people across Japan discovered evidence for a previously overlooked third ancestral group, challenging the long-accepted "dual origins" theory. The newly identified ancestry appears linked to the ...

A remote island between Australia and Antarctica is showing signs of a dramatic climate transformation. Scientists found storms over Macquarie Island now unleash much heavier rainfall than they did decades ago, soaking ecosystems and altering fragile ...

Humans may have returned to Britain far earlier than scientists once believed -- not long after the last ice sheet began retreating. New evidence suggests people were already moving into the British Isles around 15,200 years ago, tracking herds of .. ...

Researchers have uncovered unexpectedly high levels of silicone-based pollutants called methylsiloxanes floating through the atmosphere across cities, rural regions, and even forests. Much of the pollution appears to come from vehicle emissions, ...

Cacti may look like slow, stubborn desert survivors, but they're actually evolving at lightning speed. Scientists studying more than 750 cactus species discovered that what really drives the explosion of new cactus species isn't flower size or ...

Scientists at UBC Okanagan have uncovered how plants produce mitraphylline, a rare natural compound with promising anti cancer potential. The team identified two enzymes that work together to build the molecule's unusual twisted structure, solving a ...

Researchers created a special kind of algae that can grab microscopic plastic pollution out of water almost like a magnet. The algae produce limonene, an orange-scented oil that helps them bind to water-repelling microplastics, forming easy-to-remove ...

A bizarre new giant dinosaur discovered in Argentina is giving paleontologists a fresh look at how Jurassic titans evolved in the Southern Hemisphere. Bicharracosaurus dionidei stretched about 20 meters long and carried a strange mix of features seen ...

Scientists revisiting mysterious 540-million-year-old microfossils from Brazil have overturned a major idea about early animal life. What were once thought to be trails left behind by tiny worm-like creatures are now believed to be fossilized ...
