Cambridge Science Festival Q&A


Dave Ansell

Chris Smith

Kat Arney

Every year the Cambridge Science Festival celebrates some of the best and most exciting science and engineering going on in the UK - and the Naked Scientists were there! We find out about the cool science of ice cream, the microscopic world of microbes, and the IgNobel awards for science at its most silly. Looking further afield, the University of Auckland's Peter Metcalf unlocks the secrets of a viral sarcophagus, and Mike Brown from the California Institute of Technology discusses the origin of some mysterious objects in the Kuiper Belt. To cool us down after all that excitement, Dave and Azi sit back and explain the best way to get a cold beer.
