Explorations in the world of science.

    Uncharted: The returning soldier

    Uncharted: The returning soldier

    In a few specific years across the 20th Century, the proportion of boys born, mysteriously spiked. We follow one researcher’s obsessive quest to find out why.
    And next, a tale of science and skulduggery. Michael Mann was a respected climate scientist, unknown outside of a small academic circle, until he produced a graph that shocked the world and changed his life forever.
    Hannah Fry explores two tales of data and discovery.

    The Life Scientific: Michael Woolridge

    The Life Scientific: Michael Woolridge

    Humans have a long-held fascination with the idea of Artificial Intelligence (AI) as a dystopian threat - from Mary Shelley's Frankenstein, through to the Terminator movies. But somehow, we still often think of this technology as 'futuristic', whereas in fact, it's already woven into the fabric of our daily lives, from facial recognition software to translator apps.
    And if we get too caught up in the entertaining sci-fi narrative around AI and the potential threat from machines, there is a more pressing danger that we overlook real and present concerns - from deep fakes to electoral disinformation.
    Michael Wooldridge is determined to demystify AI and explain how it can improve our lives, in a whole host of different ways. A professor of Computer Science at the University of Oxford, and the director of Foundational AI Research at the Alan Turing Institute, Mike believes the most common fears around this technology are "misplaced".
    In a special 300th edition of The Life Scientific, recorded in front of an audience at London's Royal Institution (RI), Mike tells Jim al-Khalili how he will use this year's prestigious RI Christmas Lectures to lift the lid on modern AI technology and discuss how far it could go in future. Mike also reminiscences about the days when sending an email was a thrilling novelty, discusses why people love talking to him about the Terminator at parties, and is even challenged to think up a novel future use of AI by ChatGPT.

    The Life Scientific: Mercedes Maroto-Valer

    How do you solve a problem like CO2?
    As the curtain closes on the world’s most important climate summit, we talk to a scientist who was at COP 28 and is working to solve our carbon dioxide problem.
    Professor Mercedes Maroto-Valer thinks saving the planet is still Mission Possible - but key to success is turning excess of the climate-busting gas, carbon dioxide, into something useful. And as Director of the Research Centre for Carbon Solutions at Heriot-Watt University and the UK’s Decarbonisation Champion, she has lots of innovative ideas on how to do this.
    She also has a great climate-themed suggestion for what you should say when someone asks your age…

    The Life Scientific: Sir Harry Bhadeshia

    The Life Scientific: Sir Harry Bhadeshia

    The Life Scientific zooms in to explore the intricate atomic make-up of metal alloys, with complex crystalline arrangements that can literally make or break structures integral to our everyday lives. Professor Sir Harry Bhadeshia is Professor of Metallurgy at Queen Mary University of London and Emeritus Tata Steel Professor of Metallurgy at the University of Cambridge. He’s been described as a ‘steel innovator’ – developing multiple new alloys with a host of real-world applications, from rail tracks to military armour. Harry’s prolific work in the field has earned him widespread recognition and a Knighthood; but it's not always been an easy ride... From his childhood in Kenya and an enforced move to the UK as a teenager, to the years standing up to those seeking to discredit the new path he was forging in steel research - Jim Al-Khalili discovers that Harry's achievements have required significant determination, as well as hard work.

    The Life Scientific: Cathie Sudlow

    The Life Scientific: Cathie Sudlow

    “Big data” and “data science” are terms we hear more and more these days. The idea that we can use these vast amounts of information to understand and analyse phenomena, and find solutions to problems, is gaining prominence, both in business and academia. Cathie Sudlow, Professor of Neurology and Clinical Epidemiology at the University of Edinburgh, has been at the forefront of enabling health-related research using ever-increasing datasets. She tells presenter Jim Al-Khalili why this type of research matters and how the COVID-19 pandemic changed attitudes towards data in healthcare. Over the course of her career, Cathie has held a variety of roles at different organisations, and she is currently Chief Scientist and Deputy Director at Health Data Research UK. She believes that there is no room for prima donnas in science, and wants her field to be open and collaborative, to have the most impact on patients’ lives.

    The Life Scientific: Sir Michael Berry

    The Life Scientific: Sir Michael Berry

    Professor Jim Al-Khalili meets one of Britain's greatest physicists, Sir Michael Berry. His work uncovers 'the arcane in the mundane', revealing the science that underpins phenomena in the world around us such as rainbows, and through his popular science lectures he joyfully explains the role of quantum mechanics in phones, computers and the technology that shapes the modern world. He is famed for the 'Berry phase' which is a key concept in quantum mechanics and one Sir Michael likes to explain through an analogy of holding a cat upside down and dropping it, or parallel parking a car.
