Does new science get us closer to finding out how life on earth began?

Perhaps it’s the biggest question science has left to answer, how did life begin? Now, molecular biologists in Cambridge university have discovered tiny molecules of RNA which they say might provide some clues. Science journalist and author Philip Ball explains what we know and whether we’ll ever find the origins of life on earth. Professor Michael Wooldridge has given this year’s Royal Society’s Michael Faraday Prize lecture. He speaks to Tom Whipple about why the AI we have is not what he wanted it to be; rational. And science columnist at the Financial Times Anj Ahuja brings her favourite new science to discuss.
