In the latest instalment of our weekly science and technology podcast, we welcome guest Lucy Hawking, the daughter of legendary physicist Stephen, and co-author of a new children's book with him.
George's Secret Key to the Universe follows the story of a child who is enthralled by space and, handily, has access to a supercomputer that can draw doors to anywhere in the cosmos - but what's it like trying to interest children in science and technology?
Elsewhere we discuss the scientific tussle over the fossilised "Hobbit", hear from Chris Rapley - the new director of London's Science Museum - and discuss the UK's DNA database.
