A new type of artificial blood has been created which, in the future, could bring people back from the dead - or what we think of now as dead, at least. This special fluid has been shown to preserve the organs of dead pigs, long after what was previously thought possible - which the team says could be a game-changer for organ transplants.

Rowan talks to legendary writer Neil Gaiman about the new Netflix series, out this week, based on his smash-hit Sandman comics. They also discuss the function of dreams, and the inspiration Neil draws from them.

This week we also chew over the recent massive news that DeepMind’s artificial intelligence AlphaFold has predicted the structure of nearly all proteins known to science. It is, says the team, as monumental as the discovery of the structure of DNA. The team explains how transformative this could be in areas like disease prevention.

Leaving Earth, we talk with cosmologist Laura Mersini-Houghton about her theory that we live in just one of a vast multiverse of universes, a subject she tackles in her new book ‘Before the Big Bang’.
