A Robot That Melts and Reforms Researchers have devised a robot that can liquefy and then reform—an characteristic inspired by sea cucumbers that rapidly change their stiffness. The shape-shifting invention can move between liquid and solid states by making clever use of materials. It’s composed of a metal with a low-melting point called gallium which researchers then embedded with magnets to control movement. Through the …

World’s Oldest Fossilized Brain Discovered A 525-million-year-old fossil of an extinct worm-like animal known as the Cardiodictyon catenulum was first discovered in China in 1984, but only recently have scientists found that the barely half-an-inch animal has a brain. Using a technique called “chromatic filtering,” scientists were able to reveal the animal’s nervous system and brain in an unsegmented head. Not only is this finding …
