    The Life Scientific: Raymond Schinazi

    In recent decades, we have taken huge steps forward in treating formerly fatal viruses - with pharmacological breakthroughs revolutionising treatment for conditions such as HIV, hepatitis and herpes. Raymond Schinazi has played a big role in that revolution. Ray was born in Egypt, where his mother’s brush with a potentially deadly illness during his childhood inspired a fascination with medicine. His childhood was scattered; after his family were forced to leave their homeland and travelled to Italy as refugees, Ray ended up on a scholarship to a British boarding school - and subsequently went on to study and flourish in the world of chemistry and biology. Today, Ray is the director of the Laboratory of Biochemical Pharmacology at Emory University in Atlanta, where he also set up the renowned Center for AIDS Research. His work in the early days of HIV studies led to drugs that many with the virus still take today; while his contribution to developing a cure for Hepatitis C has saved millions of lives around the world. Speaking to Jim al-Khalili, Ray reflects on his route to success and explains why he is confident that more big breakthroughs are on the horizon.

    The Life Scientific - Janet Treasure

    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.

    The Life Scientific: Anne Child

    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.

    The Life Scientific: Conny Aerts

    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. 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. Recorded at the 2024 Cheltenham Science Festival, Prof 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.

    The Life Scientific: Dr Nira Chamberlain

    When does a crowd of people become unsafe? How well will the football team Aston Villa do next season? When is it cost-effective to replace a kitchen? The answers may seem arbitrary but, to Nira Chamberlain, they lie in mathematics. You can use maths to model virtually anything.

    The Beaches

    A top secret little-known mission that changed the outcome of World War II. Not Alan Turing's Enigma code-breaking mission but a daring foray, conducted behind enemy lines on the shores of Normandy. Harrison Lewis and wetland scientist Christian Dunn re-enact one of the most remarkable feats of the Second World War and discover the intricate details of the daring but forgotten science that underpinned D-Day.

    Protein: Powerhouse or piffle?

    Take a trip around the supermarket and you'll see shelves of products claiming to be 'high in protein'. Scroll through your social media and you'll find beautiful, sculpted people offering recipes and ideas for packing more protein into your diet. Science presenters Dr Julia Ravey and Dr Ella Hubber have noticed this too. They wanted to unpick the protein puzzle to find out what it does in our bodies and how much we really need. Can this macronutrient really help us lose weight, get fit and be healthier? Along the way, they speak to Professor Giles Yeo from the University of Cambridge, Bridget Benelam from the British Nutrition Foundation, Paralympian hopeful Harrison Walsh, and food historian Pen Vogler.

    The Life Scientific: Mike Edmunds

    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.
