From anorexia nervosa to binge-eating, eating disorders are potentially fatal conditions that are traditionally very difficult to diagnose and treat - not least because those affected often don’t recognise that there’s anything wrong. But also because of the diverse factors that can influence and encourage them. Janet Treasure is a Professor of Psychiatry at King’s College, London - where she's focused on understanding the drivers behind these disorders, to help develop more effective treatments. Her study of twins in the 1980s offered one of the earliest arguments of a genetic link to anorexia, rather than the purely psychological motivations accepted at the time; while her most recent work explores holistic ways to better treat these conditions.Speaking to Jim Al-Khalili, Janet explains the work that's revealed anorexia's roots in both body and mind - as well as how attitudes towards eating disorders are slowly changing.

Marfan syndrome is a genetic disorder that makes renders the body’s connective tissues incredibly fragile; this can weaken the heart, leading to potentially fatal aneurysms. What’s more, anyone with the condition has a 50/50 chance of passing it on to their children.Dr Anne Child is a clinical geneticist who’s dedicated her professional life to finding answers and solutions for people affected by Marfan’s. Born in Canada, she met her British future-husband while working in Montreal in a case she describes as "love at first sight" - and in the 1970s she relocated her life to the UK.There, an encounter with a Marfan patient she was unable to help set Anne on a career path for life. She subsequently established the team that discovered the gene responsible for Marfan's, and founded the Marfan Trust to drive further research. Since then, life expectancy for those with the condition has jumped from 32 years old, to over 70. Speaking to Professor Jim Al-Khalili, Anne shares how she and her team achieved this remarkable turnaround.Presented by Jim Al-Khalili Produced by Lucy Taylor

Many of us have heard of seismology, the study of earthquakes; but what about asteroseismology, focusing on vibrations in stars?Conny Aerts is a Professor of Astrophysics at the University of Leuven in Belgium - and a champion of this information-rich field of celestial research. Her work has broken new ground in helping to improve our understanding of stars and their structures.It hasn’t been an easy path: Conny describes herself as always being “something of an outlier” and she had to fight to follow her dream of working in astronomy. But that determination has paid off - today, Conny is involved in numerous interstellar studies collecting data from thousands of stars, and taking asteroseismology to a whole new level. In an epsiode recorded at the 2024 Cheltenham Science Festival, Professor Jim Al-Khalili talks to the pioneering Belgian astrophysicist about her lifelong passion for stars, supporting the next generation of scientists, and her determination to tread her own path.

What is the universe made of? Where does space dust come from? And how exactly might one go about putting on a one-man-show about Sir Isaac Newton? These are all questions that Mike Edmunds, Emeritus Professor of Astrophysics at Cardiff University and President of the Royal Astronomical Society (RAS), has tackled during his distinguished career. And although physics is his first love, Mike is fascinated by an array of scientific disciplines - with achievements ranging from interpreting the spread of chemical elements in the Universe, to decoding the world’s oldest-known astronomical artefact. Recording in front of an audience at the RAS in London, Professor Jim Al-Khalili talks to Mike about his life, work and inspirations. And who knows, Sir Isaac might even make an appearance…Produced by Lucy Taylor.

Neuroscientist Hannah Critchlow discusses the complexities of the brain, character, behavior, and collective intelligence. She shares insights on brain activity, individual trajectories, and the potential of a 'super brain'. The podcast includes an experiment measuring brain waves during meditation and explores advancements in neuroscience for mental health.

The reputation of the nuclear industry has had highs and lows during the career of Dr Fiona Rayment, the President of the Nuclear Institute. But nowadays the role of nuclear science and engineering has become more widely accepted in the quest for carbon net zero.Growing up in Hamilton, Scotland during a time of energy insecurity, Fiona was determined to understand more about why her school lacked the energy to heat up all of the classrooms or why there were power cuts causing her to have to do her homework by candlelight - and in nuclear she knew there was a possible solution. But it’s not just in clean energy that Fiona has spent her career, she’s also been involved in investigating how nuclear science can be used in treating cancer and space travel, as well as promoting gender diversity in the nuclear industry. Speaking to Professor Jim Al-Khalili, Fiona discusses how she’s always tried to keep close to the science during her career in order to keep her ‘spark’!Produced by Jonathan Blackwell

Dr. Nick Longrich, a palaeontologist, shares how he discovers new dinosaurs from overlooked bones. He talks about uncovering new species, childhood adventures on Kodiak Island, nature's influence on his work, and the complexities of identifying new dinosaur species. The podcast also delves into the controversy surrounding the classification of Tyrannosaurs and the value of scientific openness in paleontology.

Dr Sheila Willis is a forensic scientist who was Director General of Forensic Science Ireland for many years. She has spent her life using science to help solve cases, working on crime scenes and then analysing material in the lab, and presenting scientific evidence in court.It’s a complicated business. Forensic science relies on powerful technology, such as DNA analysis, but it cannot be that alone - it’s also about human judgement, logical reasoning and asking the right questions. It is these fundamentals of forensic science that Sheila has fought for through her long career and what she fears may be becoming lost from the field now.We find out what happens when the two very different worlds of science and the law clash in the courtroom. How to walk the line of presenting scientific evidence where there is pressure to be definitive where often science cannot be - and what this part of the job has in common with food packaging.And what makes a good forensic scientist? We’ll turn the studio at London’s Broadcasting House into a live crime scene to see if host Professor Jim Al-Khalili would be any good as a forensic investigator…Produced by Gerry Holt

Professor Charles Godfray discusses the role of parasitic wasps in fighting diseases like Malaria and the challenge of feeding a global population of 9 billion. He explores sustainable food production methods and the ethical considerations of genetically modified organisms. The podcast also covers his career transition to leading solution-oriented research initiatives and groundbreaking projects in brain tissue reconstruction.

Sir Jonathan Van-Tam, or ‘JVT’ as he's arguably better known, first came to widespread public attention in his role as Deputy Chief Medical Officer during the Covid-19 pandemic.But even before that, Jonathan had built an impressive career based on a long-held fascination with respiratory illness and infectious diseases. He’s worked across the public and private sectors, contributing significantly to improving our understanding of influenza and treatments to address such viruses. It’s hard to believe that back in his teens, JVT – the man who advised the nation on pandemic precautions and helped make the UK’s vaccine roll-out possible – nearly didn’t get the grades he needed to go to medical school. But early challenges aside, Jonathan went on to discover a love for both medical research and public speaking: making complex public health messages easier to digest – not least by using analogies relating to his beloved football. Speaking to Professor Jim Al-Khalili in the first episode of a new series of The Life Scientific, Jonathan discusses his life and career: from academic emphasis in childhood and imposter syndrome at medical school, to pandemic pressures around Covid-19 and big birthday celebrations.Produced by Lucy Taylor.
