in a ceremony that was held on 5 December in the ceremonial Hall of the university of Copenhagen, the UNESCO Niels Bohr Gold Medal was awarded for special contributions to ground-breaking research in physics and open international collaboration. cern received the medal “in recognition of its outstanding global action in promoting scientifi c co-operation across borders”, which is particularly appropriate given the themes of the 60th anniversary this year (p5 and p58). Also honoured with the medal were Jimmy Wales, the founder of Wikipedia – in recognition of “his invaluable contribution 21 IEEE NUCLEAR SCIENCE SYMPOSIUM SEMICONDUCTOR X-RAY AND GAMMA-RAY DETECTORS & MEDICAL IMAGING& MEDICAL CONFERENCE to free, quality knowledge access” – and Alain Aspect of Ecole Polytechnique,
