A Question of Science

Professor Brian Cox takes a deeper dive into the science of fertility, with a panel of returning experts answering more of your questions.  Should we sequence the DNA of embryos and use A.I. to choose which to implant? Are ultra-processed foods and microplastics really effecting fertility? And will new technologies mean humans could one day reproduce like squid?See omnystudio.com/listener for privacy information.

Professor Brian Cox takes a deeper dive into the science of cancer, with a panel of returning experts answering more of your questions.

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?    From mechanical implants to lab-grown organs to whether humans could evolve to live in space, the discussion delves into what’s possible today and where science might take us next.  Panellists  Mark Pollock – Explorer, motivational speaker and Chairman of Collaborative Cures George Malliaras – Prince Philip Professor of Technology, University of Cambridge Madeline Lancaster – Group Leader, Medical Research Council (MRC) Laboratory of Molecular Biology    Robin Lovell-Badge – Group Leader, Stem Cell Biology and Developmental Genetics Laboratory, Francis Crick Institute  Watch the video version of this episode and read a transcript on our website: www.crick.ac.uk/podcast/buildahuman   A BBC Studios Production for the Francis Crick Institute.   Music by John Biddle  © BBC Studios / Francis Crick Institute 2025   See omnystudio.com/listener for privacy information.

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  Watch the video version of this episode and read a transcript on our website: www.crick.ac.uk/podcast/nutrition   A BBC Studios Production for the Francis Crick Institute.    Music by John Biddle © BBC Studios / Francis Crick Institute 2025 See omnystudio.com/listener for privacy information.

Professor Brian Cox and our expert panel explore the science of fertility.   Making babies is big business but our scientific understanding of fertilisation, pregnancy and embryo development is surprisingly limited.     In this episode, our panel discuss emerging technologies that could shape the future of fertility and tackle audience questions on declining sperm counts, egg freezing and the ethics of genetic screening.  Panellists: Joyce Harper – Professor of Reproductive Science, UCL Gunes Taylor – Molecular Biologist, University of Edinburgh Naomi Moris – Group Leader, Developmental Models Laboratory, Francis Crick Institute   Lucy van de Wiel – Senior Lecturer in Global Health & Social Medicine, King’s College London                                                                                                                                                   Watch the video version of this episode and read a transcript on our website: www.crick.ac.uk/podcast/fertility A BBC Studios Production for the Francis Crick Institute Music by John Biddle © BBC Studios / Francis Crick Institute 2025   See omnystudio.com/listener for privacy information.

Professor Brian Cox and our expert panel are talking all things ancient DNA. Over the past 50 years, new technology has allowed researchers to sequence and study centuries-old DNA taken from ancient, long-buried human remains. This new insight into our past has led to a whole new understanding of our ancestors, from our migration across the globe, to the environmental changes we’ve experienced, and even the spread of ancient deadly pandemics like the black plague. Our panel of scientists answers questions from a studio audience about the usefulness of commercial DNA tests, the true meaning of ancestry, and what our ancient genetic material could reveal about our future. Panellists Pooja Swali – Research Fellow in Pathogen Genomics, UCL Pontus Skoglund – Group Leader, Ancient Genomics Lab, Francis Crick Institute Adam Rutherford – Lecturer in Biology and Society, UCL Tom Booth – Senior Research Scientist and Archaeologist, Francis Crick Institute Watch the video version of this episode and read a transcript on our website: www.crick.ac.uk/podcast/ancientDNA.
