Scientists from Tufts and Harvard created microscopic robots from human cells. AdvertisementScientists have created tiny biological "robots" from lung cells that they hope could one day travel around our bodies, regenerating damaged tissues and treating disease. Their research, published Thursday in the journal Advanced Science, raises new questions about how human cells assemble and work together. The same research team had previously created similar tiny robots, or xenobots, from cells sourced from embryos of the African clawed frog. AdvertisementAlhough they're created from human cells, Levin said the anthrobots didn't have a full life cycle and so aren't considered as fully-fledged organisms.
