The science of epigenetics.

As well as discussing the badger cull in the UK and geo-engineering, this show reports from the British Science Festival in Newcastle where the inaugural Huxley debate took place. Alok Jha interviews the protagonists, Prof Gambling Tim Spector and Prof George Davey Smyth, who debate the emerging study of epigenetics – changes in gene expression during one generation that may be inherited by the next. Has the whole field been overblown?
