    This 100 million-year-old snake had hind legs and a lost bone that changes evolution
    24/04/26 08:59:58
    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
    24/04/26 10:14:27
    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.

    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.
    For the first time, scientists pinpoint the brain cells behind depression
    23/04/26 11:55:24
    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.
