Adam Rutherford presents the weekly digest of science in and behind the headlines. Joining him on the programme this week is Dr Ian Crawford from Birkbeck College, University of London, who will be discussing the future of human space flight and what it holds now that the final shuttle missions are almost completed. Also on the show; we find out what daffodils are really made of and we visit the science museum where the orginal workshop of engineer James Watt is about to be opened to the public. Finally, the champion of science that makes us laugh and think Marc Abrahams, the creator of the Ig Nobel awards, is in the studio.
