Alok Jha selects his favourite bits from the show over the past 12 months, including interviews with Stephen Hawking and Simon Baron-Cohen, the end of the space shuttle programme, imaging the female brain during orgasm, and the dawning of a new era in particle physics with the potential discovery of the Higgs boson.
In 2011, there were also shows featuring Steven Pinker on human aggression, Carlos Frenk on dark matter, and the human heart.
