Tiny 'living robots' made from FROG embryos could be used to destroy cancer cells

Tiny'Living robots' named Xenobots have been created from frog embryos and they could be used to destroy cancer cells or remove microplastics from the oceans. They were developed by researchers from Vermont University and Tufts University who adapted stem cells taken from the embryo of the African frog Xenopus Laevis. The bots are just a 25th of an inch wide (1mm) and can be programmed to perform a range of tasks including delivering medicine directly to a point in the body. Researchers say the new'artificial cells' can be shaped in any way necessary for the task at hand and are'indestructible' and able to self repair. 'They're neither a traditional robot nor a known species of animal.
