Continuing our annual tradition of watching the Nobel Prize announcement and making a video in the immediate aftermath. This year's prize was awarded jointly to Robert Lefkowitz and Brian Kobilka "for studies of G-protein-coupled receptors". Our video features Professor Martyn Poliakoff and special guest Barrie Kellam from the University of Nottingham School of Chemistry.
