    2018 Nobel Prize winner, Donna Strickland, on laser physics
    When the first laser was built in 1960, it was an invention looking for an application. Science fiction found uses for these phenomenally powerful beams of light long before real world applications were developed. Think Star Wars light sabres and people being sliced in half. Today lasers are used for everything from hair removal to state of the art weapons. Working with her supervisor Gerard Mourou in the 1980s, the Canadian physicist, Donna Strickland found a way to make laser pulses that were thousands of times more powerful than anything that had been made before. These rapid bursts of intense light energy have revolutionised laser eye surgery and, it’s hoped, could open the doors to an exciting range of new applications from pushing old satellites out of earth’s orbit to treatments for deep brain tumours. Donna tells Jim Al-Khalili why she wanted to work with lasers and what it feels like to be the first woman to win a Nobel Prize for Physics in 55 years. Producer: Anna Buckley

    Gwen Adshead on treating the minds of violent offenders
    Whether it’s a news story or television drama, human violence appals and fascinates in equal measure. Yet few of us choose to dwell on what preoccupies the mind of a perpetrator for long. Professor Gwen Adshead, however, thinks about little else. As a Forensic Psychotherapist, she works with some of the most vilified and rejected members of society. They are the violent offenders who are detained in prisons and in secure NHS hospitals, like Broadmoor, whose actions have been linked to their mental illness. Gwen has sought to understand the psychological mechanisms behind their violent behaviour so that she can help them. A pioneer in the field, she provides an environment in which men and women are encouraged to speak the unspeakable and think the unthinkable, in the hope that they will one day be able to change their minds.Producer: Beth Eastwood

    2018 Chemistry Nobel Prize winner, Sir Gregory Winter
    In an astonishing story of a scientific discovery, Greg Winter tells Jim Al-Khalili how decades of curiosity-driven research led to a revolution in medicine. Forced to temporarily abandon his work in the lab when a road rage incident left him with a paralysed right arm, Greg Winter spent several months looking at the structure of proteins. Looking at the stunning computer graphics made the pain in his arm go away. It also led him to a Nobel Prize winning idea: to ‘humanise’ mouse antibodies. A visit to an old lady in hospital made Greg determined to put his research to good use. He fought hard to ensure open access to the technology he invented and set up a start up company to encourage the development of therapeutic drugs. It took years to persuade anyone to fund his Nobel Prize winning idea that led to the creation of an entirely new class of drugs, known as monoclonal antibodies. In 2018, the market for these drugs, which include Humira for rheumatoid arthritis and Herceptin for breast cancer, was worth $70 billion. Producer: Anna Buckley

    Sue Black on women in tech
    Sue Black left home and school when she was 16. Aged 25, she attended an access course to get the qualifications she needed to go to university to study computer science. It was a bit lonely being the only student in a mini- skirt surrounded by a sea of suits, but she came top of the class nonetheless. She signed up to do a PhD (not really knowing what a PhD was) and worked on the ripple effect in software. What happens when you change one bit of code? Does it mess up everything else? A lot of new software is created by building on and adapting existing programmes so these are important questions to ask. In 2003 she embarked on a three year campaign to save Bletchley Park where ten thousand people built some of the first computers and cracked the Enigma code used by the Nazis during World War Two. More than half of the people who worked there were women. No-one had any previous experience of computers. And more than half a century on, there are fewer women working in tech than there were in the 1960s. Sue is determined to change this backwards step. Perhaps another Bletchley Park recruitment drive is needed to encourage more people, women in particular, to engage with tech and help to build our future? Producer: Anna Buckley
