Odour enthusiast Will Andrews from Proctor and Gamble's perfume creation team tells us about the science of smells and predicts that future perfumes may remind us of PlayStations and warm electronics.
Will also teaches us how to smell like an expert, and conducts a fragrance test live in the studio.
Next week he will be giving a lecture on the subject at the Royal Institution in London.
In the newsjam, the panel discusses what the outcome of Britain's general election could mean for science, and the discovery of the remains of a possible new species of human ancestor, Australopithecus sediba.
