xenobots

Lex Fridman talks with Tufts biologist Michael Levin about bioelectricity, embryogenesis, xenobots and how cells collectively pursue goals. They range into cognition, evolution and the possibility of aliens.

Biologist Michael Levin explains the bioelectric layer that coordinates cells to build organs and bodies, showing footage of two-headed worms and introducing xenobots. He discusses implications for medicine and the nature of life.
