Scientists from UVM and Tufts repurposed 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.

“These are novel living machines,” says UVM robotics expert Joshua Bongard.

They’re neither a traditional robot nor a known species of animal.

It’s 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
