One day at the New England Aquarium in Boston, biophysicist Kit Parker saw a jellyfish and said “I know I can build that.” As Nature reports, when the idea came to the Harvard University professor, he saw it as a way to understand the “fundamental laws of muscular pumps” that could eventually be used to create replacements for damaged human hearts. With help from other researchers at Harvard and the California Institute of Technology, a juvenile moon jellyfish was created with a single layer of rat heart muscle. When an electric field was applied to the artificial jellyfish, it would move like the real creature would, and similar to how a muscular pump would react to electric pulses. According to The Guardian , the jellyfish took four..
