All Headlines
This 100 million-year-old snake had hind legs and a lost bone that changes evolution
Nearly 100 million years ago, snakes weren’t the sleek, limbless creatures we know today—they still had hind legs and even a cheekbone that has almost vanished in modern species. A remarkably preserved fossil of Najash rionegrina from Argentina has reshaped how scientists think about snake origins, suggesting early snakes were large, wide-mouthed predators rather than tiny burrowers.
Stunning 132 million-year-old dinosaur tracks are rewriting history
A long-standing mystery in southern Africa’s fossil record is beginning to unravel. After massive lava flows 182 million years ago seemed to erase evidence of dinosaurs in the region, scientists have now uncovered surprising new clues along the Western Cape coast. Dozens of dinosaur tracks, about 132 million years old, have been discovered in a tiny stretch of rock near Knysna—making them the youngest ever found in southern Africa.
Ancient mass grave reveals how a pandemic wiped out a city 1,500 years ago
A newly confirmed mass grave in ancient Jordan offers chilling insight into one of history’s first pandemics. Hundreds of plague victims were buried within days, revealing how the Plague of Justinian devastated entire communities. The findings show that people who usually lived spread out across regions were suddenly concentrated in death. It’s a powerful reminder that pandemics don’t just spread disease—they reshape how societies live and collapse.
Scientists find perfect fossils in rust beneath Australian farmland
Beneath the dry farmland of New South Wales lies a hidden window into a lost rainforest teeming with life from 11-16 million years ago. At McGraths Flat, scientists have uncovered fossils preserved in astonishing detail—not in typical rock like shale or sandstone, but in iron-rich sediment once thought incapable of such preservation. Tiny iron particles filled and captured entire cells, preserving everything from insect organs to fish eye pigments and delicate spider hairs.
Astronomers may have found a strange new kind of cosmic explosion
A mysterious cosmic explosion has astronomers buzzing, as a strange event may hint at an entirely new kind of stellar cataclysm. After detecting ripples in space-time, scientists spotted a fast-fading red glow that initially looked like a rare kilonova—the kind of collision that forges gold and uranium. But just days later, the signal shifted, behaving more like a supernova, leaving researchers puzzled. Now, some think they may have witnessed something never seen before: a “superkilonova.”
NASA scientist says a "fifth force" may be hiding in our solar system
Scientists are grappling with a cosmic mystery: why does the Universe behave differently on massive scales compared to our own solar system? While distant galaxies reveal clear signs of something bending the rules of gravity—often attributed to dark energy or a hidden “fifth force”—everything nearby seems to follow Einstein’s playbook perfectly.
Hidden voids found in Menkaure pyramid hint at secret entrance
A fresh mystery is unfolding inside Egypt’s pyramids. Researchers have discovered two hidden air-filled voids lurking behind the smooth eastern face of the Menkaure pyramid—an area long suspected to conceal something unusual. Using advanced, non-invasive techniques like radar and ultrasound, the team pinpointed these cavities with surprising precision, lending strong support to the idea that a secret entrance may exist.
Scientists warn about golden oyster mushrooms sold in Florida markets
The golden oyster mushroom may be a culinary hit, but it’s becoming an ecological problem. Scientists warn it’s spreading quickly through U.S. forests, where it outcompetes native fungi and reduces biodiversity. In just a decade, it has appeared in more than 25 states, largely due to human cultivation and transport. Its silent expansion is now raising concerns about long-term impacts on forest ecosystems.
For the first time, scientists pinpoint the brain cells behind depression
Scientists have identified two specific types of brain cells that behave differently in people with depression, offering a clearer picture of what is happening inside the brain. By analyzing donated brain tissue with advanced genetic tools, the researchers found changes in neurons linked to mood and stress, as well as in immune-related microglia cells. These differences point to disruptions in key brain systems and reinforce that depression is rooted in biology, not just emotions.
These 80-year-olds have the memory of 50-year-olds. Scientists now know why
A rare group of adults over 80, known as SuperAgers, are rewriting what we thought was possible for the aging brain. With memory abilities comparable to people decades younger, their brains either resist or withstand the damage typically linked to Alzheimer’s disease. Decades of research reveal that their social lifestyles and unique brain biology may hold the key to preserving cognitive function. Scientists believe these insights could pave the way for new strategies to delay or even prevent de
This simple fatty acid could restore failing vision
Scientists at UC Irvine have found a way to potentially reverse age-related vision loss by targeting the ELOVL2 “aging gene” and restoring vital fatty acids in the retina. Their experiments in mice show that supplementing with specific polyunsaturated fatty acids—not just DHA—can restore visual function and even reverse cellular aging signs.
AI just discovered new physics in the fourth state of matter
Physicists have taken a major step toward using AI not just to analyze data, but to uncover entirely new laws of nature. By combining a specially designed neural network with precise 3D tracking of particles in a dusty plasma—a strange “fourth state of matter” found from space to wildfires—the team revealed hidden patterns in how particles interact. Their model captured complex, one-way (non-reciprocal) forces with over 99% accuracy and even overturned long-held assumptions about how these force
