In this week's Science Weekly, Alok Jha meets author Donovan Hohn who was inspired by the epic journey of a rubber duck to write Moby Duck, an exploration of the sea and an insight into oceanography.
Plus, science writer John Whitfield discusses his latest book People Will Talk: The Surprising Science of Reputation.
John and Alok are joined by Robin McKie, science and technology editor for the Observer, to discuss the reading habits of baboons and the latest research into gravitational waves.
