Instead, in configurations designed by algorithms and constructed by humans, those cells have been assembled into something new: the first-ever robots constructed entirely out of living cells.

The creators have called them xenobots; tiny, submillimetre-sized blobs containing between 500 and 1,000 cells that have been able to scoot across a petri dish, self-organise, and even transport minute payloads.
