Our biological sex affects every cell in our body, so how does it influence our health - from embryo development through to the risk of disease and diagnosis? How and why do some conditions affect females and males differently? And what can we do to ensure medicine is safe and effective for everyone, after decades of male biology bias?

Across autoimmune disorders, cancer, dementia, heart disease and even responses to everyday medications, sex‑based biological differences can shape who becomes ill, how symptoms appear and what treatments work.

Join our expert panel as they explore sex differences in biology, hormones and gene regulation.

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.

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’.

Professor Brian Cox and an expert panel tackle the technology, politics and ethics of space exploration.  

From space tourism to the search for life on Mars, space is a rapidly expanding, multi-trillion-pound global industry, driven by scientific, commercial and often political goals.  But what are the rules of space and who makes them?    

In this episode, the panel answers audience questions on how Earth’s geopolitics are reflected in space, when asteroid mining might become a reality, and whether those star-buying kits are value for money.

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.

Professor Brian Cox and our expert panel explore ageing, longevity and the science behind our lifespans. 

Human life expectancy has increased steadily over the last 200 years, but we may be reaching a ceiling. Is this our biological limit, or could the next big scientific breakthrough push it even further? Might repurposing existing drugs help extend our lifespans? Our panel of researchers answers audience questions about the societal impacts of longer lives, our cellular ticking clock, and whether we can learn anything from the 400-year-old sharks of the North Atlantic.
