  • Scientists in the United States have created the world’s first “living machines”.
  • These are tiny robots built from the cells of the African clawed frog (Xenopus laevis), that can move around on their own.
  • They have named the millimetre-wide robots “xenobots” — after the species of aquatic frog found across sub-Saharan Africa from Nigeria and Sudan to South Africa, Xenopus laevis.
  • The xenobots can move toward a target, perhaps pick up a payload (like a medicine that needs to be carried to a specific place inside a patient) and heal themselves after being cut.
