For some animals, losing a limb is a decidedly permanent affair. But for salamanders, particularly axolotls, amputation is just a temporary affliction. Not only can they grow back entire limbs in as little as six weeks, they can also regenerate heart and even brain tissue. So, how does this astonishing adaptation work? Jessica Whited explores the incredible regenerative capacity of salamanders. [Directed by Anton Bogaty, narrated by Jack Cutmore-Scott, music by Cem Misirlioglu, WORKPLAYWORK].
