  • As the famous frog once said, it's not easy being green. And when it comes to decarbonising industry, indeed, reducing emissions of all sorts, the task is a complex one.

    Fossil fuels are used to manufacture some of mankind’s most ubiquitous products, from plastics to cement to steel; and even in areas where we’re trying to improve our footprint, there are repercussions. Mining lithium for electric car batteries isn’t exactly without impact. Add to the mix stories of corporations prioritising profits, and governments focusing on short-term popular policies – and it would be easy to feel disheartened.

    Professor Anna Korre says her role is to be the champion of science in this debate: providing clear evidence to help reduce environmental impacts, while allowing vital production processes to continue.

    Anna is an environmental engineer at Imperial College London and Co-Director of the university’s Energy Futures Lab. Her work has led to a risk model that's now used in mining operations around the world – and her current research into sub-surface CO2 storage could hold the key to decarbonising British industry. But as she tells Jim Al-Khalili, social and familial expectations when she was growing up in her native Greece meant her succesful career in engineering very nearly didn't happen...

  • Rosalie David is a pioneer in the study of ancient Egypt. In the early 1970s, she launched a unique project to study Egyptian mummified bodies using the techniques of modern medicine. Back then, the vast majority of Egyptologists regarded mummies as unimportant sources of information about life in ancient Egypt. Instead they focussed on interpreting hieroglyphic inscriptions, the written record in papyrus documents and archaeological remains and artefacts. Rosalie David proved that the traditionalists were quite wrong.

    Professor David’s mummy research started at the Manchester Museum when she began to collaborate with radiologists at the nearby Manchester Royal Infirmary, taking the museum’s mummies for x-rays at the hospital. Her multi-disciplinary team later moved to a dedicated institute at the University of Manchester, the KNH Centre for Biomedical Egyptology. Over the decades, the team there has made remarkable discoveries about disease and medicine in ancient Egyptian society, providing a new perspective on the history of medicine and giving extraordinary insights into the lives of individuals all those years ago.

    Rosalie tells Jim Al-Khalili about her journey from classics and ancient history to biomedicine, including some of her adventures in Egypt in the 1960s. She talks about some of her most significant research projects, and the 21st Century forensic detective work on the mummy of a young woman which revealed a gruesome murder 3,000 years ago...

  • In the summer of 2003, Europe experienced its most intense heatwave on record - one that saw more than 70,000 people lose their lives. Experiencing the effects whilst on holiday in Tuscany, climate scientist Peter Stott was struck by the idea that just maybe, he could use a modelling system developed by his team at the UK’s Met Office Hadley Centre, to study extreme weather events such as this very heatwave mathematically; and figure out the extent to which human influences were increasing their probability.

    That’s exactly what he went on to do - and, through this work and more, Peter has helped to shine a light on the causes and effects of climate change.His career, predominantly at the Met Office Hadley Centre, has seen him take on climate change sceptics and explain the intricacies of greenhouse gas emissions to global leaders. His work with the Intergovernmental Panel on Climate Change even earned him a share of the 2007 Nobel Peace Prize.

    But the biggest challenge remains: Peter talks to Jim Al-Khalili about whether humanity can adapt quickly enough to deal with the increasingly dangerous effects of our warming world...

  • Imagine a nanoparticle, less that a thousandth of the width of a human hair, that is so precise that it can carry a medicine to just where it’s needed in the body, improving the drug’s impact and reducing side effects. Ijeoma Uchegbu, Professor of Pharmaceutical Nanoscience at University College London, has spent her career with this goal in mind. She creates nanoparticles to carry medicines to regions of the body that are notoriously hard to reach, such as the back of the eye and the brain. With clinical trials in the pipeline, she hopes to treat blindness with eyedrops, transform pain relief and tackle the opioid crisis. Ijeoma took an unconventional route into science. Growing up in the UK and in Nigeria, she tells Professor Jim Al-Khalili her remarkable life story, from being fostered by a white family in rural Kent, while her Nigerian parents finished their studies, to struggling to pay the bills through her PhD as a single mum with young children. So passionate is Ijeoma to spread her love of science, she’s even turned to stand-up comedy to help get her message across!

  • Darren Croft studies one of the ocean’s most charismatic and spectacular animals – the killer whale. Orca are probably best known for their predatory behaviour: ganging up to catch hapless seals or attack other whales. But for the last fifteen years, Darren Croft’s focus has been on a gentler aspect of killer whale existence: their family and reproductive lives . Killer whales live in multi-generational family groups. Each family is led by an old matriarch, often well into her 80s. The rest of the group are her daughters and sons, and grand-children. Especially intriguing to Darren is that female orca go through something like the menopause - an extremely rare phenomenon in the animal kingdom, only documented in just five species of toothed whales and of course in humans. Halting female reproduction in midlife is an evolutionary mystery, but it is one which Darren Croft argues can be explained by studying killer whales.Darren is Professor of Animal Behaviour at the University of Exeter. He talks to Jim Al-Kalili about his research on killer whales, his previous work revealing sophisticated social behaviour in fish, his life on the farm, and the downsides and upsides of being dyslexic.

  • Bill Gates is one of the world's best-known billionaires - but after years at the corporate coalface building a software empire and a vast fortune, his priority now is giving that wealth away. And his ethos for doing it has been shaped by science.

    Famed for co-founding Microsoft, in recent decades Bill’s attention has turned to philanthropy via The Gates Foundation: one of the largest charities in the world. Since its inception in 2000, the organisation's helped tackle issues around health, education, inequality and climate change in some of the world’s poorest countries, with an undeniable impact: from contributing to the eradication of wild poliovirus in Africa, to helping halve global child mortality rates within 25 years.

    But, as Jim Al-Khalili discovers, for a man with lofty ambitions and an even loftier bank balance Bill has surprisingly humble tastes - from cheeseburgers and a bingeable spy series, to a good game of pickleball...

  • The final episode in this series of The Life Scientific is a journey through space and time, via black holes and wormholes, taking in Nobel-prize-winning research and Hollywood blockbusters!

    Kip Thorne is an Emeritus Professor of Theoretical Physics at Caltech, the California Institute of Technology, and someone who’s had a huge impact on our understanding of Einsteinian gravity. Over the course of his career Kip has broken new ground in the study of black holes, and been an integral parts of the team that recorded gravitational waves for the very first time – earning him a share in the 2017 Nobel Prize for Physics.

    He went on to promote physics in films: developing the original idea behind Christopher Nolan’s time-travel epic Interstellar and, since then, advising on scientific elements of various big-screen projects; including, most recently, the Oscar-winning Oppenheimer.

    In a special edition of The Life Scientific recorded in front of an audience of London’s Royal Institution, Professor Jim Al-Khalili talks to Kip about his life and career, from his Mormon upbringing in Utah to Hollywood collaborations – all through the lens of his unwavering passion for science.

  • The engineering industry, like many other STEM sectors, has a problem with diversity: one that Dawn Bonfield believes we can and must fix, if we're to get a handle on much more pressing planetary problems...

    Dawn is a materials engineer by background, who held roles at Citroën in France and British Aerospace in the UK. But, after having her third child, she made the difficult decision to leave the industry - as she thought at the time, for good. However a short spell working in post-natal services and childcare gave her new skills and a fresh perspective. This led to Dawn rehabilitating the struggling Women in Engineering Society and creating ‘International Women In Engineering Day’, which has just celebrated its 10th anniversary.

    Today, she’s Professor of Practice in Engineering for Sustainable Development at King’s College London, and the founder of Magnificent Women: a social enterprise celebrating the story of female engineers over the past century. She’s also President of the Commonwealth Engineers’ Council and has had her work supporting diversity and inclusion recognised with an MBE.

    Dawn talks to Professor Jim Al-Khalili about why 'inclusive engineering' should not be dismissed as tokenism, and why she's optimistic about the engineering sector's power to change the world.

  • In recent decades, we've 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's confident that more big breakthroughs are on the horizon.

  • 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.

  • 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…

  • 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 Professor 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’s explored the idea that much of our character and behaviour is hard-wired into us before we’re even born. And most recently she’s 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 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’!

  • We are fascinated by dinosaurs. From blockbuster hits to bestselling video games, skeleton exhibitions to cuddly plushies, the creatures that once roamed the planet have fully captured our imagination, giving us a portal to a completely alternative Earth. And it’s likely new species are still out there, waiting to be found...

    Dr Nick Longrich is a palaeontologist and senior lecturer at the University of Bath, and he studies the dinosaur bones that many have overlooked. By rummaging through the back rooms of museums, he finds traces of never-before-described dinosaurs and goes on the hunt for other specimens to confirm or deny his hunch. Through these adventures, he’s discovered over a dozen new species, painting a more detailed picture of our prehistoric world.

    Nick is also fascinated by rare ‘one in a million year’ events – like asteroid collisions or mega volcanic eruptions – and investigates how the event that wiped out the dinosaurs created the world we live in today. From an Island off the coast of Alaska, Jim Al-Khalili discovers how Nicks early immersion in nature has trained his brain to spot the subtle differences in the world around us that many would overlook.

  • 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…

  • Professor Charles Godfray, Director of the the Oxford Martin School tells Jim Al-Kahlili about the intricate world of population dynamics, and how a healthy obsession with parasitic wasps might help us solve some of humanity's biggest problems, from the fight against Malaria to sustainably feeding a global community of 9 billion people.

  • 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.
