    Sir Magdi Yacoub on pioneering heart transplant surgery

    To access this episode early and ad-free, subscribe to BBC Podcast Premium on Apple Podcasts. The episode will be available for free with adverts on 19th March. What does it take to earn the nickname, ‘The Leonardo da Vinci of heart surgery’? That's the moniker given to today's guest - a man who pioneered high-profile and often controversial procedures, but also helped drive huge medical progress; carrying out around 2,000 heart transplants and 400 dual heart-lung transplants during his 60-year career. Sir Magdi Yacoub is Emeritus Professor of Cardiothoracic Surgery at Imperial College London, and Director of Research at Harefield Hospital’s Magdi Yacoub Institute. Inspired by a surgeon father and impacted by the tragic early death of his aunt from a heart condition, his medical career includes various surgical firsts alongside numerous research projects, to further our understanding of and ability to treat heart disease. He headed up the teams that discovered it is possible to reverse heart failure, and that successfully grew part of a human heart valve from stem cells for the first time. But it hasn't always been plain sailing. At times, his work – such as early, unsuccessful transplant attempts, or using a baboon as a life-support system for a baby – attracted serious public criticism. Speaking to Professor Jim Al-Khalili, Sir Magdi reflects on the highs and lows of his cardio career, and offers his advice to the next generation of surgeons and researchers hoping to make their mark in heart medicine.

    Tim Peake on his journey to becoming an astronaut and science in space

    What's it like living underwater for two weeks? What's the trickiest part of training to be an astronaut? What are the most memorable sights you see from space? Several extreme questions, all of which can be answered by one man: Major Tim Peake. After a childhood packed with outdoor adventures, via the Cub Scouts and school Cadet Force, Tim joined the British Army Air Corps and became a military flying instructor then a test pilot; before eventually being selected as a European Space Agency (ESA) astronaut. In 2015, Tim became the first British ESA astronaut to visit the International Space Station. Over the course of a six-month mission, he took part in more than 250 scientific experiments and worked with more than two million schoolchildren across Europe. In a special New Year’s episode recorded in front of an audience at London’s Royal Society, Professor Jim Al-Khalili talks to Tim about his lifelong passion for adventure, the thrill of flight and why scientific experiments in space are so important.

    Anna Korre on capturing carbon dioxide and defying expectations

    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 on the science of Egyptian mummies

    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...

    Peter Stott on climate change deniers and Italian inspiration

    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...

    Ijeoma Uchegbu on using nanoparticles to transform medicines

    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! Presented by JIm Al-Khalili Produced by Beth Eastwood

    Darren Croft on killer whale matriarchs and the menopause

    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 on vaccines, conspiracy theories and the pleasures of pickleball

    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...

  • Peak Danger is Season 2 of Extreme, the BBC podcast about those who chase the impossible... who strive for superhuman status and refuse to accept that life has any limits. Every season tells an unforgettable, action-packed story about people who’ve pushed their minds and bodies to the very edge – but at what cost? A mountain of trouble... In August 2008, around 30 climbers took on K2. Over 2 disastrous days, 11 of those people would lose their lives. This is the story of what really happened. Sitting on the border between China and Pakistan, K2 is a perfect pyramid that pierces through the clouds. It looks like a kid’s drawing of a mountain…but this terrifying peak is anything but child’s play. Newlyweds Cecilie Skog and her husband Rolf Bae loved climbing mountains almost as much as they loved one another. In the summer of 2008, they embarked on a honeymoon like no other, when they decided to climb K2. What happened next would change their lives and the lives of everyone around them…forever. A devastating avalanche scatters high altitude climbers across K2’s steep slopes. Life and death rescue missions quickly get underway. Who can be saved… before time runs out? Historian and podcaster Natalia Mehlman Petrzela returns with a sky-high story of human vs nature, and of survival against all the odds. What does it really take to push yourself to the brink of human possibility? How does it feel to stand with the whole world at your feet? And is it ever worth risking death… in order to feel alive?

And: The Abercrombie Guys. Investigating sexual exploitation claims against the former CEO of fashion giant Abercrombie & Fitch. Delve into a World of Secrets: the global investigations podcast from the BBC. Uncovering stories around the world and telling them, episode by episode, with gripping storytelling. Latest season: The Bad Guru. A yoga school in London. A guru running from the police. How did Miranda get sucked in? Journalist Cat McShane investigates the international yoga movement headed by Gregorian Bivolaru, the spiritual guide arrested by French police in November 2023 and charged with human trafficking, organised kidnapping, rape and organised abuse of weakness by members of a sect. “Nobody joins a cult. You just get sucked in,” says Penny, the mother of a university tutor from London. In 2017, Penny’s daughter Miranda joins a yoga charity with studios in London and Oxford. The classes make Miranda feel amazing and the people make her feel loved. “There was this sense that these people cared,” says Miranda. But as Miranda becomes more deeply involved with the international yoga movement that her group in London is part of, her mother Penny starts to worry. “When she rang us, she'd be speaking in very hushed tones,” says Penny. Miranda has fallen under the spell of guru Gregorian Bivolaru. She joins thousands of his followers from around the world on a free holiday at a coastal resort in Romania. It’s part of a search for spiritual enlightenment which will see her driven through Paris blindfolded and doing sex work in Prague. This series includes explicit sexual content and strong language. Previous seasons of World of Secrets: Season 5: Finding Mr Fox. Investigating a plot to smuggle around a hundred millions of dollars’ worth of drugs from Brazil to Europe and the miscarriage of justice that followed. But where is the man Brazilian police believe to be at the centre of it all? Season 4: Al Fayed, Predator at Harrods. Egyptian billionaire Mohamed Al Fayed – then owner of Harrods, one of the most famous shops in the world – is accused of rape and attempted rape by women who worked for him. Now they refuse to be silenced any longer. Season 3: The Apartheid Killer. All the victims were black and the youngest was just 12 years old. Some relatives are still searching for the graves. They were killed during a three-year bloodbath in the 1980s, in the South African city of East London – by one person. He killed so many, he lost count. In piecing together this story, we expose the disturbed past and racial injustices of South Africa itself. Season 2: The Disciples. The cult of Nigerian prophet TB Joshua. A story of miracles, faith and manipulation, told by people from around the world, who gave up everything for one of the most powerful religious figures of the century. Lured by TB Joshua’s claimed healing powers, they live as disciples in a guarded Lagos compound, cut off from family and friends. Season 1: The Abercrombie Guys. An investigation into claims of sexual exploitation made against the former CEO of fashion giant Abercrombie & Fitch. He and his British partner were accused by several men, recruited for sex events they hosted around the world.
