?How do animals regrow their limbs? And why can't humans do it?
?Jessica Whited
?Subtitle: ??English

?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].

?David R. Flum
?Subtitle: ??English | ??Turkish

?In 1961, an Antarctic expedition took a harrowing turn: Dr. Leonid Rogozov began feeling feverish, with an excruciating pain in his right side. It soon became clear that he had appendicitis. While Rogozov’s predicament was extreme, appendicitis is not uncommon; affecting roughly one in 12 people. So, what causes appendicitis? And why is this organ so prone to bursting? David R. Flum investigates. [Directed by Igor Ćorić, Artrake Studio, narrated by Addison Anderson, music by Salil Bhayani, cAMP Studio].
