Hosted by comedian Susan Morrison, top academics explore dangerous ideas. Dr Ross Donaldson (Heriot-Watt University) asks should we regulate light to allow scientists to create new laser gadgets? Or are the boffins out of control? And Nicola Osborne (The University of Edinburgh) explores what creative work looks like when we use data and technology to imagine wild new ideas, from data-driven knitwear and robot avatars in space, to new forms of performance.
