Scientists from the University of Vermont and Tufts re-purposed living cells scraped from frog embryos and assembled them into entirely new life forms. These tiny “xenobots” can move toward a target and heal themselves after being cut. They’re neither a traditional robot nor a known species of animal and so they are a new class of artifact: a living, programmable organism. The new creatures were designed on a supercomputer at UVM, and then assembled by biologists at Tufts University. Scientists think they could be useful for:
searching out radioactive contamination
gathering plastic pollution in the oceans
traveling in arteries to scrape out plaque
