No larger than the average coin, the ray contains both biological and artificial parts—rat heart cells grown on a silicon mold fitted over a 3D printed gold skeleton. And it can move. Using a technique called optogenetics, the heart cells are genetically modified to contract when they’re hit with a beam of light.   Watch how it’s done: The heart cells are taken from two-day-old rat… read more
