The xenobots are made of cells taken from the African clawed frog, or Xenopus laevis. The researchers hope that one day these xenobots - described by the same team in a paper published nearly two years ago - could be programmed to perform useful functions such as finding cancer cells in the human body or trapping harmful microplastics in the ocean. ![]() "You can think about this like using the different cells building blocks like you would build with LEGO or with Minecraft," Douglas Blackiston, a co-author of the study, tells NPR. The discovery involves a xenobot – a simple, "programmable" organism that is created by assembling stem cells in a Petri dish - and is described by a team of researchers from Tufts University, Harvard University and the University of Vermont in a paper published this week in the Proceedings of the National Academy of Sciences. Among other things, the findings could have implications for regenerative medicine. Scientists say they've witnessed a never-before-seen type of replication in organic robots created in the lab using frog cells. A dozen organisms designed by artificial intelligence known as xenobots (C-shaped beige) beside loose frog stem cells (white).
