Bio-Hybrid Stingray Robot – This tiny stingray is a robot powered by rat muscle cells. After going to the aquarium, lead scientist Kit Parker told his teammate: “We’re going to build a ray, we’re going to build it out of a rat, and we’re going to make it light-guided.”
The project was mainly done for the wow factor, but Parker hopes to one day build a whole human heart out of genetically engineered tissue using this type of technology.
