The Life Scientific

Jim al-Khalili talks to botanist Geoff Palmer, the UK's only professor of brewing and distilling, about revolutionising the malting industry and his unusual scientific career after arriving from Jamaica in 1955 as a 14 year old boy. When he went for an interview for an MSc in 1964 the representative from the Ministry of Agriculture suggested he go back home and grow bananas. Why? Because he didn't know the difference between wheat and barley. Undeterred he went on to become a world authority on barley, brewing and distilling and Scotland's first black professor. His research on how malt could be made more quickly saved the brewing industry millions. But he says, it's only through good luck and with the help of good Samaritans that his career took the course it did, helping him get to university and even to finish school. Now at the age of 75, he's still fighting to make education and a scientific career available to everyone, regardless of their background.

EO Wilson has been described as the "world's most evolved biologist" and even as "the heir to Darwin". He's a passionate naturalist and an absolute world authority on ants. Over his long career he's described 450 new species of ants. Known to many as the founding father of socio-biology, EO Wilson is a big hitter in the world of evolutionary theory. But, recently he's criticised what's popularly known as The Selfish Gene theory of evolution that he once worked so hard to promote (and that now underpins the mainstream view on evolution). A twice Pulitzer prize winning author of more than 20 books, he's also an extremely active campaigner for the preservation of the planet's bio-diversity: he says, "destroying rainforest for economic gain is like burning a Renaissance painting to cook a meal".EO Wilson talks to Jim al-Khalili about his life scientific.

Forensic chemist Niamh Nic Daeid talks to Jim Al-Khalili about investigating fires and analysing legal highs.Her team were involved in studying the infamous Philpott case in Derby when six children tragically died in a fire set by their parents, Mick and Mairead. They devised experiments to find out why, despite having smoke alarms fitted inside the house, none of the children woke up.Chemistry has also been pushed to the limits to identify 'legal highs', or Novel Psychoactive Substances. Around 350 new drugs are released on to the market every month, with Europe a hotspot for buyers. Plus, Niamh talks about the serious problems facing the world of forensic science. The field, she says, is in crisis. With rock-bottom research budgets, and the list of miscarriages of justice growing, how can we fix forensic science?Producer: Michelle Martin.

Carlos Frenk, Ogden Professor of Computational Cosmology at the University of Durham, studies the universe, but not by spending nights looking out at the dark skies through telescopes. Rather he creates the cosmos on computers. He is also one of the Gang of Four of astrophysics who thirty years ago came up with one of the most important theories in their field. They worked out that the universe is full of cold dark matter. In 2011 Carlos Frenk and his colleagues were awarded the Gruber prize, one of the leading accolades in astronomy, for their theory.Carlos Frenk discusses this mysterious missing mass, which is still mysterious and missing, with Jim al-Khalili. They talk about modelling the universe inside computers, and how Carlos persuaded his university to hire the architect Daniel Liebskind to design a building for creative thinking about the cosmos.

Dorothy Bishop is a world-leading expert in childhood language disorders. Since the 1970s, she has been instrumental in bringing to light a little-known language disorder that may affect around two children per class starting primary school.'Specific Language Impairment', or SLI, was originally deemed to be the fault of lazy parents who didn't talk to their children. But through her pioneering studies on twins, Dorothy found a genetic link behind this disorder, helping to overturn these widespread misconceptions. Dorothy talks to Jim Al-Khalili about how families react when they discover there's a genetic basis to their problems, and why this language impairment isn't as well known as other conditions, like autism and dyslexia.A critic of pseudoscience and media misreporting, Dorothy discusses her experiences of speaking out against folk psychology and bad science journalism.Producer: Michelle Martin.

Neurosurgeon Henry Marsh talks to Jim Al-Khalili about slicing through thoughts, hopes and memories. Brain surgery, he says, is straightforward. It's deciding whether or not to operate that's hard.The stakes are high and it's never clear cut. He often dreads having to talk to patients and their families. Damage to healthy brain cells can result in a dramatic change to someone's quality of life; but if a bit of a tumour remains, it's likely to grow back. "How do you tell someone that the best option may be to go away and die?"Once, against his professional judgment, Henry went ahead with surgery because the patient wanted him to operate. The patient died and he blames himself for not being stronger. He talks openly about the cemetery that all doctors inevitably carry with them; and why he would rather be seen as a fallible human being, than either a superhero or villain. Perhaps it's inevitable that doctors are put on a pedestal but it can be unhelpful.Despite a chronic lack of science at school and university, Henry decided to become a neurosurgeon, having found general surgery rather disgusting. Soon after, his three month old son had surgery for a brain tumour: an experience which, he says, helped him to appreciate the fog of anxiety and concern that descends on the people he treats.Getting the balance right between compassion and detachment is a constant challenge. And Henry admits, he pioneered brain surgery under local anaesthetic, in part as a way of confronting head on the almost 'Jekyll and Hyde like split' between being a surgeon in the operating theatre and a friendly consultant who talks to and cares for his patients.

Kate Jones is Professor of Ecology and Biodiversity at UCL and the Institute of Zoology. An expert in evolution and extinction, her special interest is in bat research and conservation.Bats make up one in five of all mammal species on Earth, from the miniscule bumblebee bat to the enormous megabat.As well as controlling harmful insects bats also pollinate a large variety of crops, from bananas to blue agave plants that are used to make tequila.Kate has pioneered ground-breaking technologies that allow the public to monitor bats, including the citizen science website Bat Detective.This work led her to investigate human infectious diseases, including those spread through animals. Together with a global team of researchers, they drew up a map of global hotspots to try and predict where the next 'zoonotic' disease will emerge.Producer: Michelle Martin.

Anil Seth is professor of cognitive and computational neuroscience at the Sackler Centre at the University of Sussex, where he studies consciousness.His research has taken him in all kinds of directions, from reading philosophy, to computing and virtual reality, and mapping the brain. As well as running the interdisciplinary centre and carrying out experiments that test ideas about consciousness, Anil Seth has co-written a popular book, The 30 second brain, and was the consultant on Eye Benders, the winner of the Junior Royal Society Book Prize in 2014.He talks to Jim al-Khalili about how scientists can study altered states of consciousness, such as sleep and coma. He explains how he uses virtual reality to understand conditions where our idea of ourselves is distorted, such as in the Alice in Wonderland syndrome.

Fat, sugar, salt - we all know we should eat less of them, and take more exercise, but as a nation with an ever expanding waistline we are becoming increasingly overweight.Jim al-Khalili talks to Professor Susan Jebb, the UK's authority on obesity, who has spent much of her career trying to help us put those good intentions into practice.Her challenge is not for the faint hearted. When she first got interested in obesity, as a research scientist, rates were already on the rise. Yet no one took the problem seriously. Today, with over sixty percent of adults overweight or obese, Susan remains unwavering in her commitment to ensuring we do.As Professor of Diet and Population Health at Oxford University and Chair of the government's Responsibility Deal Food Network, she wants all of us and the food industry to improve the nation's health by translating the science of what we eat into practice.And health is what it's all about. Obesity now poses such a danger that it's been dubbed the 'new smoking'.Produced by Beth Eastwood.

Sir Nigel Shadbolt, Professor of Artificial Intelligence at Southampton University, believes in the power of open data. With Sir Tim Berners-Lee he persuaded two UK Prime Ministers of the importance of letting us all get our hands on information that's been collected about us by the government and other organisations. But, this has brought him into conflict with people who think there's money to be made from this data. And open data raises issues of privacy.Nigel Shadbolt talks to Jim al-Khalili about how a degree in psychology and philosophy lead to a career researching artificial intelligence and a passion for open data.
