Researchers at Harvard University have built an artificial jellyfish using a sheet of silicone and rat heart cells, which they lovingly call a medusoid. When electricity is run through the tank, it swims exactly like a real jellyfish.
"Morphologically, we've built a jellyfish. Functionally, we've built a jellyfish. Genetically, this thing is a rat," says Kit Parker, a biophysicist at Harvard University in Cambridge, Massachusetts, who led the work. The project is described today in Nature Biotechnology1.
Parker's lab works on creating artificial models of human heart tissues for regenerating organs and testing drugs, and the team built the medusoid as a way of understanding the "fundamental laws of muscular pumps". It is an engineer's approach to basic science: prove that you have identified the right principles by building something with them.
