Scientists have created living robots that can self-heal and record memories

Scientists have used the stem cells of frogs to create new living robots that can heal themselves and even record memories. Named “Xenobots” after the Xenopus laevis frog that supplies their cells, the machines are an upgraded version of devices that were first unveiled last year. Like their predecessors, the new Xenobots can work together in groups and self-heal. But version 2.0 are faster, live longer, and can record information about their surroundings. The researchers believe future models could detect diseases and deliver drugs to specific areas of the body. Programming nature Biologists at Tufts University made the tiny robots by microinjecting amphibian…
