It Isn’t Just Science Fiction Anymore

Remember when you first read a science fiction story with nanobots teaming inside a person? Were you afraid? I thought it was cool. But that was fiction. And nanobots aren’t real–yet. However, tiny robots inside your body isn’t just science fiction anymore. A team of researchers at the University of Vermont have created a new life-form. Computer-Designed Lead author and doctoral student, Sam Kriegman, used an evolutionary algorithm. He fed it into the Deep Green supercomputer cluster at UVM. The computer ran thousands of simulated designs over the next few months. The basic biophysics of what single frog skin and cardiac cells can do drove its decisions. It discarded designs that failed and refined the more successful ones. After a hundred independent runs of the algorithm, the research team chose the most promising designs. Repurposed A book is made of wood. But it is not a tree. The dead cells have been repurposed to serve another need. UVM News From there the research went to biologists at Tufts University. Michael Levin, who directs the Center for Regenerative and Developmental Biology at Tufts, and his team brought the computer designs to life. With vital help from microsurgeon Douglas Blackiston, they harvested stem cells […]
