Episodes

Richard Henderson zooms in on the molecules of life 13.02.2018

What once took decades, now takes days, thanks to an astonishingly powerful new technique invented by Richard Henderson, winner of the 2017 Nobel Prize for Chemistry. Richard grew up in a remote village in the Scottish borders exploring the countryside and reading the weekly bundles of comics sent by his great aunt, as part of a care package for his family. When he started work at the Laboratory o...

Wendy Barclay and the flu virus 30.01.2018

2018 is having the worst flu season for seven years. Influenza continues to make a lot of us feel very ill, and it can of course be fatal. Wendy Barclay, Professor Virology at Imperial College London, has spent many years trying to learn everything she can about the way flu viruses behave. These microscopic infectious organisms are formidable foes - they mutate all the time, making it hard to pred...

Eugenia Cheng on the mathematics of mathematics 23.01.2018

Nothing annoys Eugenia Cheng more than the suggestion that there is no creativity in mathematics. Doing mathematics is not about being a human calculator, she says. She doesn't spend her time multiplying big numbers in her head. She sits in hotel bars drawing (mainly arrows) with a fine quill pen, thinking about how ideas from different areas of mathematics relate to one another and hoping to reve...

Eben Upton on Raspberry Pi 16.01.2018

When Eben Upton was in his twenties, he wanted to get children thinking about how computers think, to boost the number of people applying to read computer science at university. He dreamt of putting a chip in every classroom. The result was Raspberry Pi, a tiny gadget, little bigger than a credit card, that can be hooked up to any keyboard and monitor, to create a programmable PC. And it's cheap....

Adrian Thomas on the mechanics of flight 31.10.2017

As a young man Adrian Thomas took to the skies in order to better understand the mechanics of flight. He's a paragliding champion and a Professor of Zoology who specialises in the dynamics of insect flight. On a typical day, he can be found inside a wind tunnel that's been custom-made to study insects instead of jumbo jets. Using lines of smoke and high speed video cameras, he measures exactly how...

Ellen Stofan on being NASA chief scientist 24.10.2017

When Ellen Stofan was just four years old, she witnessed the worst rocket launch-pad disaster in NASA's history convinced that her father, (who was a rocket engineer) was on board. He wasn't. Nonetheless, for many years NASA was not her favourite place. In 2013, however, she became she became their chief scientist, a post she held for 4 years. Barak Obama dreamt of putting people on the red planet...

Tim Birkhead on bird promiscuity 17.10.2017

Professor Tim Birkhead talks to Jim Al Khalili about his 40 years of research on promiscuity in birds, his love of Skomer Island and its guillemots, and the extraordinary musical talent of the male bullfinch. Tim Birkhead is an evolutionary biologist and ornithologist at the University of Sheffield. The primary focus of his research has been reproduction in birds. He pioneered the study of promisc...

Steve Cowley on Nuclear Fusion 10.10.2017

Steve Cowley has said that "fusion is arguably the perfect way to power the world". But he's had to add that "it is hard to make fusion work. Indeed, after more than 60 years of fusion research, no device has yet made more energy than it consumes". But Steve Cowley isn't giving up. He's spent over 30 years working towards making nuclear fusion a viable way of generating energy. Steve Cowley has do...

Lucie Green on the sun 03.10.2017

Lucie Green studies the sun - that giant, turbulent ball of burning gas at the centre of our solar system. Her first ambition was to become an art therapist, but she soon switched from art to astrophysics, and before long had fixed her gaze on our local star. It may be 93 million miles away, but the sun's extensive and ever changing magnetic field determines the 'weather' throughout our solar syst...

Tracey Rogers on leopard seals and Antarctica 26.09.2017

Marine ecologist Tracey Rogers talks to Jim Al Khalili about her research on one of Antarctica's top predators. This is the leopard seal - a ten foot long killer which glides among the ice floes in search of prey ranging from other seals to penguins to tiny krill. Tracey's research has encompassed the animal's prolific and eerie underwater singing to radical changes in its diet that appear to be l...

Jennifer Doudna 19.09.2017

Jennifer Doudna's research has transformed biology. And this is not an understatement. Her work has given us the tools to edit genes more precisely than ever before. Her scientific career began with work to understand the actions of RNA, part of the machinery of every cell. But, after a meeting in 2005 with a colleague at the University of California, Berkeley, where Jennifer is currently a profes...

Tamsin Mather on what volcanic plumes reveal about our planet 30.05.2017

To volcanologist Tamsin Mather, volcanoes are more than a natural hazard. They are 'nature's factories', belching out a rich chemical cocktail of gases. It's these gases or 'plumes' that fascinate her the most. She likes nothing more than crouching on a crater's edge collecting a smouldering mix of ash and gases, a clue to what's brewing deep inside. As Professor of Earth Sciences at Oxford Univer...

Tim O'Brien on transient stars and science and music festivals 23.05.2017

Tim O'Brien has earned the nickname 'the awesome astrophysicist dude from Jodrell Bank' He is Professor of Astrophysics at Manchester University, and the associate director of Jodrell Bank Observatory, best known for the giant, iconic radio dish of the world-famous Lovell telescope which sits majestically on the Cheshire plain, where he carries out research on the behaviour of transient binary sta...

Ottoline Leyser on how plants decide what to do 16.05.2017

To the untrained eye, a plant's existence may seem rather uneventful. It spends its days rooted to the spot, seemingly at the mercy of its environment. Not so, plant biologist Ottoline Leyser explains to Jim Al-Khalili. Plants are intelligent creatures that possess a unique ability to adapt in ways we animals can only dream of. They can alter their entire body plan of roots and shoots, when requir...

Fay Dowker on a new theory of space-time 09.05.2017

For a long time Fay Dowker was mathematically precocious, but emotionally uncertain. These days, despite working in an area with few academic allies, she is more confident than ever. Her approach to a Theory of Everything, known as causal set theory, acknowledges the quantum nature of the universe and takes the arrow of time more seriously than Einstein. Bye bye time travel. Fay started her Life S...

Ann Clarke on The Frozen Ark 02.05.2017

Tiny tree dwelling snails, partula, were so abundant across French Polynesia that garlands of partula shells would be presented to visitors to the islands. But when immunologist Dr Ann Clarke joined her husband, the late evolutionary biologist Professor Bryan Clarke, on expeditions to research the unique way this species had developed, a study in speciation turned, before their eyes, into a study...

Graham MacGregor on tackling the demons in our diet 25.04.2017

The food we eat is the greatest cause of death and illness worldwide. The main culprits - salt, sugar and fat - are now so embedded in our diet, in the form of processed foods, that most of us consume far too much. Yet Professor Graham MacGregor doesn't believe it's up to us to reverse this situation. It's up to the food industry, he says, who manufacture the processed foods, to take the 'rubbish'...

Liz Sockett on friendly killer bacteria 18.04.2017

Professor Liz Sockett studies an extraordinary group of predatory bacteria. Bdellovibrio may be small but they kill other bacteria with ingenious and ruthless efficiency. Liz has devoted the last fifteen years of her career as a microbiologist to work out how this microscopic killer invades and consumes its victims - victims which include a host of disease-causing bacteria which have also acquired...

Nick Fraser on Triassic reptiles 11.04.2017

Nick Fraser regularly travels back in time (at least in his mind) to the Triassic, a crazily inventive period in our evolutionary history that started 250 million years ago. Wherever there are ancient Triassic creatures buried underground, Nick is never far behind; and his 'fossil first' approach to life has been richly rewarded. In 2002, he unearthed a new species of gliding reptile in Virginia,...

Daniel Dennett on the evolution of the human brain 04.04.2017

Daniel Dennett has never been one to swallow accepted wisdom undigested. As a student he happily sought to undermine the work of his supervisor, Willard Quine. Only one of the most respected figures in 20th century philosophy, a thinker eminent enough to appear on US postage stamps. Later in Oxford, he became frustrated by his fellow philosophers' utter lack of interest in how our brains worked an...

Alison Woollard on what she has learnt from mutant worms 28.02.2017

C. elegans is a rather special worm, so-named for the elegant way it moves in sinusoidal curves. It's studied, and much loved, by thousands of scientists around the world. Alison Woollard joined this exclusive club of worm scientists when she moved to the world famous Laboratory of Molecular Biology in Cambridge, also known as 'worm Mecca' in 1995. She started her career working as a lab technicia...

Alan Winfield on robot ethics 21.02.2017

Alan Winfield is the only Professor of Robot Ethics in the world. He is a voice of reason amid the growing sense of unease at the pace of progress in the field of artificial intelligence. He believes that robots aren't going to take over the world - at least not any time soon. But that doesn't mean we should be complacent. Alan Winfield talks to Jim al-Khalili about how, at a young age, he delight...

Simon Wessely on unexplained medical syndromes 14.02.2017

Professor Sir Simon Wessely has spent his whole career arguing that mental and physical health are inseparable and that the Cinderella status of mental health funding is a national disgrace. His current role, as President of the Royal College of Psychiatrists, has given him a platform to bang the drum for parity of funding, better training for doctors and the need to reduce stigma around mental he...

Sean Carroll on how time and space began 07.02.2017

How did time and space begin? From the age of ten, Sean Carroll has wanted to know. He first read about the big bang model of the universe as a child. Later, he turned down two job offers from Stephen Hawking. The big bang model of the universe is well established but, as Sean readily admits, the big bang itself remains a mystery. In the beginning, Sean applied Einstein's theories of relativity to...

Alison Smith on algae 31.01.2017

Think of algae and you'll probably think trouble. Algal blooms turned the diving pool green at the 2016 Rio Olympics. Smelly seaweed ruins many a trip to the beach. But Alison Smith, Professor of Plant Biochemistry at the University of Cambridge, argues that we should appreciate algae more. They range in size from giant kelp to microscopic diatoms. They are found all over the world from the Arctic...
