WASHINGTON, Jan. 13 (Xinhua) -- U.S. researchers have created a "living" robot made from a single cell, a programmable organism that can move toward a designated target and repair itself after being cut open. The results were published in the National Journal
the 13th.
at the University of Vermont in the United States first ran an evolutionary algorithm on a supercomputer, simulating an organism's design based on the laws of biophysics. Researchers at Tufts University in the United States then extracted stem cells from embryos from African claws and bred them into skin cells or heart muscle cells, splitting them into individual cells and assembling them under a microscope into structures similar to lysed.
previously randomized contraction of myocardial cells that moved forward in an orderly and autonomous manner and for days or weeks in a watery environment, according to a study. Further experiments showed that the "living" robots were able to move around in circles, pushing the balls together to the center. The researchers cut the robots out of them, and they were able to stitch them up and continue working on their own, something traditional robots could not do.
" robots could be used in the future to search for radioactive contamination, collect microplastics in the sea, or remove atherosclerotic plaques from arteries, said co-author Michael Levine, a biologist at Tufts University.
