    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. 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.

    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. Presenters: Dr Julia Ravey and Dr Ella Hubber Producer: Alice Lipscombe-Southwell Editor: Martin Smith

    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.

    Hannah Critchlow

    With 86 billion nerve cells joined together in a network of 100 trillion connections, the human brain is the most complex system in the known universe. Dr Hannah Critchlow is an internationally acclaimed neuroscientist who has spent her career demystifying and explaining the brain to audiences around the world. Through her writing, broadcasting and lectures to audiences – whether in schools, festivals or online – she has become one of the public faces of neuroscience. She tells Prof Jim Al-Khalili that her desire to understand the brain began when she spent a year after school as a nursing assistant in a psychiatric hospital. The experience of working with young patients - many the same age as her - made her ask what it is within each individual brain which determines people’s very different life trajectories. In her books she explores the idea that much of our character and behaviour is hard-wired into us before we are even born. And most recently she has considered collective intelligence, asking how we can bring all our individual brains together and harness their power in one ‘super brain’. And we get to hear Jim’s own mind at work as Hannah attaches electrodes to his head and turns his brain waves into sound.

    The Life Scientific: Fiona Rayment

    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’!

    Sheila Willis

    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…
