This 100 million-year-old snake had hind legs and a lost bone that changes evolution

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.

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.

Ancient Antarctic ice is revealing a surprising new chapter in Earth’s climate story, stretching back 3 million years. By analyzing tiny pockets of trapped air and rare gases, scientists have discovered that while the planet cooled significantly—especially in the oceans—levels of key greenhouse gases like carbon dioxide and methane changed only modestly. This unexpected mismatch suggests other powerful forces, such as shifting ice sheets, ocean circulation, and Earth’s reflectivity, played major roles in driving long-term climate change.
