The Life Scientific

Callum Roberts, Professor of Marine Biology at the University of York, learnt to dive in a leaky wet suit in the North Sea when he was a boy. As a student, he was introduced to the extraordinary diversity of marine life on a coral reef in the Red Sea. His job was to count different species of fish but he also noticed several different species of fish working together to defend a common resource, l...

Stephen Reicher is a social psychologist at St Andrews University who has spent decades understanding how people behave when in a group. To do so, he's often had to immerse himself among the subjects of his studies, from the Bristol riots in 1980 to the millions of Hindu pilgrims who go to the Magh Mela. Stephen Reicher talks to Jim al-Khalili about the positive and the negative sides to a crowd a...

Next time you swear at the battery in your mobile phone, spare a thought for the chemist, Clare Grey. Having developed a new way of looking inside solids (using nuclear magnetic resonance), her interest in batteries was sparked by a man from Duracell who asked her a question at an academic conference, and charged up by some electrochemists she met playing squash. For the last twenty years she has...

Professor Sir John Burn, has made Newcastle on Tyne a centre for research on genetics and disease. He was one of the first British doctors to champion the study of genes in medicine back in the 1980s. More recently his research with families with a propensity to develop certain cancers has shown the benefits of taking aspirin as a prevention against the disease. John Burn was part of the team that...

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...

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...

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...

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....

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...

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...

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 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 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...

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'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...

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 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...

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...

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...

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...

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'...

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 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 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...

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...
