It is quite literally a festival of science on this week's show as we look back on the BA's, er, Festival of Science.
Ian Sample, James Randerson, and Alok Jha guide us through the main headlines from the event, including pioneering face recognition technology; the debate over a possible cure for autism; research into cocaine-laced banknotes; and postcode profiling.
We also have interviews with Robert Winston on transplanting pig organs into humans, and Sir Martin Rees and Ian Crawford on the British space programme. There's more too on the devastating impact of rock n' roll, which has Producer Ben in a pickle.
