In 1960, a villager found something terrifyingly creepy in Greece’s Petralona cave—a humanoid cranium with a protrusion on its forehead, fused to the cave wall. Since then, researchers have been trying to date the strange specimen and understand how it got there, but these efforts so far have yielded only a frustratingly broad age range of between around 170,000 and 700,000 years. The skull’s ambiguous stratigraphic position is also less than helpful. So a team of researchers took a slightly di

Satellites Spotted a Strange Glow in the Ocean, and Scientists Have a Wild Explanation

Since the early 2000s, scientists have been puzzled by a gleaming turquoise spot in the middle of the Antarctic Ocean showing up in satellite images. The patch is located just south of the great calcite belt, a region that's rich in the mineral form of calcium carbonate, and teeming with coccolithophores, tiny marine organisms that grow reflective calcite shells out of the mineral. The patch itself, however, has been considered far too frigid to support these tiny plankton, causing a longstand
