Professor Brian Cox and our expert panel explore the frontier of human bioengineering and building, replacing, and enhancing our bodies.
Will we ever have bionic brains and cloned humans? Is there a danger of science fiction getting too close for comfort?

Professor Brian Cox and an expert panel explore the elusive science of consciousness – what it is, how it arises, whether it can be observed in the brain, and the most compelling theories explaining it.
In a deep, often mind-bending discussion, the panel tackles the many ways of interpreting consciousness itself, and how fields like psychophysics can be used to quantify imagination and perception.
With questions from the audience, the conversation delves into hallucinations and reality, how memory helps to build identity, and whether AI could ever be conscious too.

Katharina Schmack – Consultant Psychiatrist and Group Leader, Neural Circuits and Immunity in Psychosis Laboratory, Francis Crick Institute
Steve Fleming – Professor of Cognitive Neuroscience, UCL

Professor Brian Cox and our expert panel dive into the complex world of diet, nutrition and food choices.
With new probiotic and high-protein products appearing on supermarket shelves every day and conflicting nutritional advice coming from every direction, it’s difficult to cut through the noise when it comes to what we eat.
Our panel uses expertise from their roles as nutritionists, geneticists, gastroenterologists and policymakers to answer audience questions about food advertising, wellness advice, and whether it’s really possible – or worthwhile – to avoid food ‘additives’.
Panellists
Giles Yeo – Professor of Molecular Neuroendocrinology, MRC Metabolic Diseases Unit, University of Cambridge
Christina Vogel – Professor in Food Policy and Director of the Centre for Food Policy, City St George’s, University of London
Saliha Mahmood Ahmed – Gastroenterologist and MasterChef winner, 2017
Nita Forouhi – Professor of Population Health and Nutrition, MRC Epidemiology Unit, University of Cambridge
