Lab-Made Jellyfish Hints at Heart Fix

Researchers have designed a bioengineered jellyfish that can swim, an early step in scientists’ quest for a way to make fresh tissue for patients with damaged hearts. Researchers have designed a bioengineered jellyfish that can swim, an early step toward potentially finding a way to make fresh tissue for patients with damaged hearts reports WSJ’s Gautam Naik. The lab-made jellyfish is created with a mix of silicone and rat-heart cells. Although it isn’t a living organism, the robot’s muscular structure closely resembles that of a real jellyfish, enabling it to swim freely through water. Scientists hope that such techniques will make it possible to harvest cells from one organism and then reorganize them in sophisticated…
