Meet the xenobot: world’s first living, self-healing robots created from frog stem cells

Scientists used embryonic stem cells from African clawed frogs to develop tiny robotic devices complete with skin and heart muscle and self-healing capabilities.Traditional robots “degrade over time and can produce harmful ecological and health side effects.  As biological machines, xenobots are more environmentally friendly and safer for human health.Xenobots could be used to clean up radioactive waste, collect microplastics in the oceans, carry medicine inside human bodies, or even travel into our arteries to scrape out plaque. The xenobots can survive in aqueous environments without additional nutrients for days or weeks — making them suitable for internal drug delivery.
