Scientists reassemble a frog’s living cells into robotic devices — with no electronics required. The African clawed frog, Xenopus laevis, typically lives in the streams and ponds of sub-Saharan Africa, scavenging for food that it rips apart with its feet. In January, researchers at the University of Vermont and Tufts University published a report that gave the amphibian a different lot in life. They harvested its embryonic skin and heart cells and reassembled the living matter into robotic devices — transforming Xenopus into xenobot.
Xenobots are the first robots made completely of living materials. They’re designed on a supercomputer running software that emulates natural selection…
