Quentin Cooper presents the week's digest of science in and behind the headlines. In this edition: the latest planet capable of supporting life; how the World Wide Web unveils the laws of our collective behaviour; 'dry water' - a powder that's 95% H2O; and the discovery of Francis Crick's lost correspondence, revealing the fractious exchanges between the rival parties hunting the structure of DNA. The producer is Roland Pease.
