Scientists from the United States have created self-replicating robots out of frog cells that take a shape similar to “Pac-Man”. The study was published on Monday in Proceedings of the National Academy of Science. It found that these computer-designed and hand-assembled organisms are called “xenobots” and can reproduce in a method not seen in plants or animals.
Douglas Blackiston, co-author and senior scientist at Harvard University explained “people have thought for quite a long time that we’ve worked out all the ways that life can reproduce or replicate, but this is something that’s never been observed before,”
The xenobots were initially developed in 2020 and they are made from roughly 3,000 embryonic skin cells of an African clawed frog. When they are designed properly, xenobots can swim around while collecting hundreds of single cells to put together smaller versions of themselves in their mouths. They are a size that is just visible to the human eye, it would look similar to poppy seeds moving around.
