With the help of a supercomputer, scientists have built tiny machines comprised entirely made of biological materials. Able to survive for days and even weeks, these xenobots could eventually be used ...

Computer scientists and biologists have teamed up to make a new class of living robotics that challenge the boundary between digital and biological. A xenobot, derived from the skin cells of frog ...

Although xenobots are not currently made from human embryos or stem cells, it is conceivable they could be. Their creation raises similar questions about creating and modifying ongoing life forms that ...
