Scientists created living robots out of stem cells
Scientists have created a new life form that's something between a frog and a robot. Using stem cells scraped from frog embryos, researchers from the University of Vermont (UVM) and Tufts University assembled "xenobots." The millimeter-wide blobs act like living, self-healing robots. They can walk, swim and work cooperatively. Refined, they could be used inside the human body to reprogram tumors, deliver drugs or scrape plaque out of arteries.
