Persuading the Body to Regenerate Its Limbs

(The New Yorker) – Levin had been invited to present at an A.I. conference because his work is part of a broader convergence between biology and computer science. In the past half century, scientists have come to see the brain, with its trillions of neural interconnections, as a kind of computer. Levin extends this thinking to the body; he believes that mastering the code of electrical charges in its tissues will give scientists unprecedented control over how and where they grow. In his lab, he has coaxed frogs to regenerate severed legs, and tadpoles to grow new eyeballs on their stomach.
