- Scientists of University of Vermontand Tufts University have created the world’s first living and self-healing robots Xenobots, using stem cells from frogs. It is named after the African clawed frog, Xenopus laevis from which they take their stem cells.
- The machines used are less than a millimeter (0.04 inches) wide which are small enough to travel inside human bodies. They can walk and swim, survive for weeks without food, and work together in groups.
- Xenobots could be used to clean up radioactive waste, collect micro plastics in the oceans, carry medicine inside human bodies, or even travel into our arteries to scrape out plaque.
