Chris Jackson is the kind of scientist who just loves to get out into the landscape he loves. He’s often introduced as ‘geologist and adventurer’. For the past five years he’s been Professor of Basin Analysis in the Department of Earth Sciences and Engineering at Imperial College London and he’s now about to move back to the University of Manchester, where he studied as a student, to become Professor of Sustainable Geoscience.

As a child growing up in Derby, Chris learned to love the outdoors on family trips to the Peak District. Recently, you may have seen him abseiling into a crater of an active volcano in the Democratic Republic of Congo for a BBC TV series. He’s also been telling us about the link between our planet’s geology and climate change as part of the recent Royal Institution Christmas lectures.

Chris talks to Jim al-Khalili about working in the oil and gas exploration industry at the start of his career, searching for massive deposits of salt deep inside the earth and his experience of being a black geologist.

More of us have been exposed to so more science than ever before during 2020. And our insatiable appetite for science shows no sign of diminishing. Back in 2019, most scientists struggled to get any media attention. Now scientists involved in fighting the pandemic are generating headlines almost daily. On top of working harder than ever to further our understanding of the virus, many have become public figures. Some have been caught in the headlights. Others have stepped into the footlights. Many have found themselves at the centre of highly politicised conversations - not something a scientific training prepares you for. And the fact that everyone is now an expert on R numbers and immunology has created a new set of challenges. Jim Al-Khalili explores how The Life Scientific has changed during the pandemic and asks if, during these difficult times, a new relationship between scientists and the media has been forged.

We look to science for certainty (all the more so during uncertain times) but there is no magic moment when scientists can announce with absolute certainty that ‘this is how it is’. Now that science is being reported in real time, revealing all the ups and downs on the bumpy road to discovery is there a danger that our faith in science will be undermined. Or could one legacy of the pandemic be a much greater appreciation of the true nature of scientific knowledge and how it’s formed? Has good journalism helped science to progress by synthesising scientific findings and interpreting what they mean? And, when the pandemic is over,

Neil Ferguson is known to many as Professor Lockdown. The mathematical models he created to predict the spread of Covid-19 were influential but, he says, it took him quite a long time to be persuaded that full lockdown was a good idea. A physicist by training, Neil switched from studying string theory to the spread of disease and presented scientific advice to government during the BSE crisis, an outbreak of foot and mouth disease in livestock in 2001 and the swine flu pandemic of 2009. In January 2020, he issued his first report on Covid-19 estimating the extent of the outbreak in Wuhan City in China. In March, he predicted that 510,000 people in the UK could die if nothing was done to mitigate the spread of this pandemic. Does he stand by that prediction? And how worried is he now? Jim Al-Khalili talks to Neil Ferguson about his life and work, the tricky relationship between politics and science and asks if he has any regrets about lockdown.

Sarah Gilbert started working on a vaccine for Covid-19 just as soon as the virus genome was sequenced. Within weeks, she had a proof of principle. By early April, her team at the Jenner Institute in Oxford had manufactured hundreds of doses ready for use in clinical trials. In phase one of these trials, completed in July, this vaccine was shown to be safe for use in a thousand healthy volunteers, aged between 18 and 55. It also provoked exactly the kind of immune response to Covid-19 that Sarah was hoping to achieve. Larger scale clinical trials are currently underway in the UK, South Africa and Brazil. If everything goes according to plan and the vaccine meets all the necessary regulatory standards, it will be manufactured in multiple locations including the Serum Institute in India and made available for use in low to middle income countries. AstraZeneca has already committed to making two billion doses, each costing about $4. The UK has an order in for 100 million. Sarah talks to Jim Al-Khalili about her life and work. As a young woman, she nearly gave up on a career in science. Now she’s in charge of one the most successful vaccine projects in the world. How did Sarah and her Oxford team get so far, so fast in developing a vaccine against Covid-19?

Steve Haake,has spent much of his career using technology to help elite sports people get better, faster and break records. He has turned his hand to the engineering behind most sports, from studying how golf balls land, to designing new tennis racquets and changing the materials in ice skates. He’s now Professor of Sports Engineering at Sheffield Hallam University and was the Founding Director of the Advanced Wellbeing Research Centre there.

Since the 2012 London Olympics, Steve has also been working to improve the health and wellbeing of all of us. As Chair of the Parkrun Research Board he’s heavily involved in this international phenomenon in which thousands of people have sprinted, jogged and stumbled around a 5-kilometre course on Saturday mornings, which he’s shown really does encourage people to be generally more active.

Jim al-Khalili talks to Steve Haake about how he got from a physics degree to being one of the leading sports engineers in the world, and how we can all improve our health by moving more.

When Francesca Happé started out as a research psychologist thirty years ago, she thought she could easily find out all there was to know about autism – and perhaps that wouldn’t have been impossible as there were so few papers published on it. Francesca’s studies have increased our knowledge of how people with autism experience the world around them, and their social interactions. She’s looked at their brains using various imaging techniques, studied the families of people with autism to explore their genetics, and raised awareness of how the condition can appear differently in women than in men. Jim al-Khalili talks to Francesca, now Professor of Cognitive Neuroscience at the Institute of Psychiatry, Psychology and Neuroscience in London, about her research career and her current projects, including how people with autism experience mental health issues, such as PTSD.

Professor Heather Koldewey wants to protect our oceans from over-fishing and plastic pollution. An academic who is not content to sit back and let the science speak for itself, she wants to turn science into action and has found conservation allies in some unexpected places. Working with a carpet manufacturer, she created Net-Works, a business that turns old fishing nets into high-end carpet tiles and she has collaborated with Selfridges department store to give marine conservation a make-over. A research career that began studying the genetics of brown trout in Welsh rivers took her to the Philippines to save seahorses and a job running the aquarium at London Zoo. In 2018, she was made a National Geographic Fellow. Heather tells Jim Al-Khalili why, despite all the challenges to marine life, she remains an ‘ocean optimist’ and how she learned to drop her ‘scientific seriousness’.

Professor Dale Sanders has spent much of his life studying plants, seeking to understand why some thrive in a particular environment while others struggle. His ground breaking research on their molecular machinery showed how plants extract nutrients from the soil and store essential elements. Since plants can’t move, their survival depends on these responses. In 2020, after 27 years at the University of York, he became the Director of the John Innes Centre in Norwich, one of the premier plant research institutions in the world. Meeting the food needs of a growing global population as the climate changes is a major challenge. And, Dale says, it’s not only about maximising yields. We need crops that are more resilient and more nutritious. Drought resistant crop varieties, for example. And zinc-rich white rice. Dale talks to Jim about how plant science is helping to feed the world in a sustainable way and why plant scientists don’t always get the recognition they deserve.

Professor Andrew Fabian from Cambridge's Institute of Astronomy has spent his career trying to unravel the mystery of how some of the most dramatic events in the universe can profoundly influence its evolution. For over 50 years he’s been examining our universe using X-ray satellites orbiting way above earth’s atmosphere . He’s built up compelling evidence that supermassive black holes at the heart of galaxies are the engines that drive the movement of energy through the universe and provide the building blocks for the formation of new galaxies. They're extraordianry insights, for which he’s now been awarded the 2020 Kavli Prize in Astrophysics, one of the world's most prestigious science prizes.

Jim Al-Khalili hears how Andy gets to capture epic galactic events in motion to build up a picture of this vast ecosystem - and also how he earned a place in the Guinness Book of Records for discovering the deepest note in the universe – a B flat , 57 octaves below middle C.

It’s amazing what we can learn from a pile of old bones. Having worked as a paediatric surgeon for several years (often doing the ward round on roller blades), Alice Roberts spent a decade teaching anatomy to medical students and studying human remains. A niche interest in the collar bone and how it has changed since we evolved from the common ancestor we share with other apes 6 million years ago, led her to some of the biggest questions in science. Who are we? And where do we come from? She is the presenter of several landmark TV series on human evolution and archaeology, such as The Incredible Human Journey and Digging for Britain. And in 2019 she became President of the British Science Association. In conversation with Jim Al Khalili, Alice shares her passion for the bones of our ancient ancestors and of the freshly dead, and describes her own incredible journey from a basement full of medieval bones to an eminent science communicator and public figure.
