Pretty impressive.
Scientists at Harvard University and the California Institute of Technology have created a jellyfish robot out of silicone and living muscle cells taken from a rat heart, according to an article in the journal Nature Biotechnology published today.
The researchers arranged the muscle cells on an eight-armed silicone shape so that when the cells were zapped with electricity, they would contract and the robot would swim through water like a live jellyfish, the Wall Street Journal reported.
