About the show

Science you can trust. Questions that matter.   Join Professor Brian Cox and a panel of the world’s top scientists and experts as they tackle your questions about some of the biggest science challenges facing society today.  Can we cure cancer? How do you separate nutrition fact from fiction? What do climate change and the march of AI mean for our future? Could we live forever? Each episode is recorded in front of a live audience and it’s their questions that drive the debate.  Hear from the experts who actually know what they’re talking about, including Adam Rutherford, Helen Sharman, George Monbiot, Giles Yeo, Jeanette Winterson, Rory Cellan-Jones, Paul Nurse, Kevin Fong and You, Me and the Big C’s Lauren Mahon.   With a focus on accuracy, openness, and debate, A Question of Science brings you the latest on what we know, what we don’t, and where science might take us next.  A BBC Studios production for the Francis Crick Institute, an independent charity and world-leading research lab.
