The Life Scientific

Chemical reactions are the backbone of modern society: the energy we use, the medicines we take, our housing materials, even the foods we eat, are created by reacting different substances together. If we zoom in, it’s the atoms within these substances that rearrange themselves to give rise to new substances with the properties we need.

However, chemical reactions are far from perfect. They're often inefficient and their waste prod...

Have you ever considered the lighter side of dark matter? Comedy has proved an unexpectedly succesful way to engage people with science - as today's guest knows first-hand.

Astrophysicist Catherine Heymans is a Professor at the University of Edinburgh and the current Astronomer Royal for Scotland. She’s spent her career studying dark matter and dark energy: the mysterious ingredients that make up an estimated 95% of our cosmos, but...

As a young man, traveling in Africa, Tim Coulson - now Professor of Zoology at the University of Oxford - became seriously ill with malaria and was told a second bout would probably kill him. Aged only 20, this brush with his own mortality led him to promise himself he would write a complete guide to science: life, the universe and everything. His aim was to understand the existence of all living things - no mean feat!

Over the cou...

Claudia de Rham has rather an unusual relationship with gravity.

While she has spent her career exploring its fundamental nature, much of her free time has involved trying to defy it - from scuba diving in the Indian Ocean to piloting small aircraft over the Canadian waterfalls. Her ultimate ambition was to escape gravity’s clutches altogether and become an astronaut, a dream that was snatched away by an unlikely twist of fate.

Ho...

When you think of Artificial Intelligence, does it inspire confidence, or concern?

Although it's now generally accepted that this technology will play a major role in our future, a lot of conversations around AI and machine learning come back to the argument over us losing control and robots taking over.

Happily, Neil Lawrence has a more optimistic view of the power of AI, and how we might navigate the potential pitfalls. Neil is th...

A frozen, white world at the far-reaches of the globe, where you're surrounded by snow and silence, might sound rather appealing. Factor in temperatures that drop to -57°C and a few of us might be put off - but for glaciologist Liz Morris, that's very much her happy place.

Liz is an Emeritus Associate at the University of Cambridge’s Scott Polar Research Institute, and was among the first British women scientists to work on the pla...

Welcome to a world where medicine meets politics: a space that brings together scientific research, government wrangling, public push-back and healthcare conspiracies…

Dr Anthony Fauci was the Director of America’s National Institute of Allergy and Infectious Diseases for nearly four decades, during which time he not only helped study, treat and prevent viruses such as HIV/AIDS and Covid-19; he also advised seven US Presidents, from...

Have you ever pondered the fact that the universe is expanding? And not only that, it's expanding at an increasing speed - meaning everything around us is getting further and further away?

If that isolating thought makes you feel slightly panicked, don't worry: this programme also contains wine!

Brian Schmidt is a Distinguished Professor of Astrophysics at the Australian National University, known for his work on supernovae: massiv...

How much information can you extract from a burnt fragment of human bone?

Quite a lot, it turns out - not only about the individual, but also their broader lives and communities; and these are the stories unearthed by Jacqueline McKinley, a Principal Osteoarchaeologist with Wessex Archaeology.

During her career, Jackie has analysed thousands of ancient burial sites across the British Isles, bringing to life the old traditions around...

Surgeons often have to deal with the consequences of violent attacks - becoming all too familiar with patterns of public violence, and peaks around weekends, alcohol-infused events and occasions that bring together groups with conflicting ideals.

Professor Jonathan Shepherd not only recognised the link between public violence and emergency hospital admissions, he actually did something about it.

As a senior lecturer in Oral and Maxi...

Doyne Farmer is something of a rebel. Back in the seventies, when he was a student, he walked into a casino in Las Vegas, sat down at a roulette table and beat the house. To anyone watching the wheel spin and the ball clatter to its final resting place, his choice of number would’ve looked like a lucky guess. But knowing the physics of the game and armed with the world’s first wearable computer, which he’d designed, a seemingly ran...

Elephants are the largest living land mammal and today our plant is home to three species: the African bush elephant, the African forest elephant, and the Asian elephant.

But a hundred thousand years ago, in the chilly depths of the Ice Age, multiple species of elephant roamed the earth: from dog-sized dwarf elephants to towering woolly mammoths.

These gentle giants' evolutionary story and its parallels with that of humankind has lon...

What does it take to earn the nickname, ‘The Leonardo da Vinci of heart surgery’?

That's the moniker given to today's guest - a man who pioneered high-profile and often controversial procedures, but also helped drive huge medical progress; carrying out around 2,000 heart transplants and 400 dual heart-lung transplants during his 60-year career.

Sir Magdi Yacoub is Emeritus Professor of Cardiothoracic Surgery at Imperial College Londo...

What's it like living underwater for two weeks? What's the trickiest part of training to be an astronaut? What are the most memorable sights you see from space? Several extreme questions, all of which can be answered by one man: Major Tim Peake.

After a childhood packed with outdoor adventures, via the Cub Scouts and school Cadet Force, Tim joined the British Army Air Corps and became a military flying instructor then a test pilot; ...

As the famous frog once said, it's not easy being green. And when it comes to decarbonising industry, indeed, reducing emissions of all sorts, the task is a complex one.

Fossil fuels are used to manufacture some of mankind’s most ubiquitous products, from plastics to cement to steel; and even in areas where we’re trying to improve our footprint, there are repercussions. Mining lithium for electric car batteries isn’t exactly witho...

Rosalie David is a pioneer in the study of ancient Egypt. In the early 1970s, she launched a unique project to study Egyptian mummified bodies using the techniques of modern medicine. Back then, the vast majority of Egyptologists regarded mummies as unimportant sources of information about life in ancient Egypt. Instead they focussed on interpreting hieroglyphic inscriptions, the written record in papyrus documents and archaeologi...

In the summer of 2003, Europe experienced its most intense heatwave on record - one that saw more than 70,000 people lose their lives. Experiencing the effects whilst on holiday in Tuscany, climate scientist Peter Stott was struck by the idea that just maybe, he could use a modelling system developed by his team at the UK’s Met Office Hadley Centre, to study extreme weather events such as this very heatwave mathematically; and fig...

Imagine a nanoparticle, less that a thousandth of the width of a human hair, that is so precise that it can carry a medicine to just where it’s needed in the body, improving the drug’s impact and reducing side effects. Ijeoma Uchegbu, Professor of Pharmaceutical Nanoscience at University College London, has spent her career with this goal in mind. She creates nanoparticles to carry medicines to regions of the body that are notori...

Darren Croft studies one of the ocean’s most charismatic and spectacular animals – the killer whale. Orca are probably best known for their predatory behaviour: ganging up to catch hapless seals or attack other whales. But for the last fifteen years, Darren Croft’s focus has been on a gentler aspect of killer whale existence: their family and reproductive lives . Killer whales live in multi-generational family groups. Each f...
