But Michael Levin's ideas were so wild, I decided to go back after I finished the book and look a little more closely. He is the topic of my latest story for popular science. This guy has done some crazy stuff -- he has reprogrammed the cells of frogs so that they grow six arms, induced a tadpole to grow an eye on its gut. He has even made a worm with two heads. He sent me a video that is truly spooky.

He and his colleague David Kaplan at Tufts have designed a sleeve they call a biodome. More details on the link. But they soak the amputation site in a solution that effects the flow of ions across cells membrane, then protect it from infection.....
