Adam Hart investigates the most famous and feared predator in all the ocean – the great white shark! With rows of large, serrated teeth, it’s often thought of as a ferocious man-eater and was the villain of the film Jaws – which frightened a generation of beachgoers. This star of the silver screen may be the subject of fascination and fright for many, but is it really the ultimate predator of the ocean as Hollywood has led us to believe? Adam hears what it’s like to see these sharks up-close...

Adam Hart investigates the largest terrestrial member of the weasel family – the wolverine. They’re far more than just a superhero played by Hugh Jackman! With a reputation for gluttony and ferocity, these solitary killers use snowstorms to hunt much larger prey. Found in the snowy tundra and boreal forests of the Northern Hemisphere, their future looks uncertain – they've come into conflict with Scandinavian farmers by hunting their reindeer and are threatened by climate change in North...

With the world's biodiversity being lost at an alarming rate, Alexandre Antonelli, Director of Science at the Royal Botanic Gardens, Kew, has made it his life's mission to protect it. He is a bio-geographer revealing how changes to the Earth's landscape, such as the formation of mountain ranges and rainforests, leads to the evolution of new species and causes plants, fungi and animals to move around the world. His work is a masterclass in joined-up thinking, bringing together different fields...

Astronomer Paul Murdin believes a good imagination is vital for scientists, since they're so often dealing with subjects outside the visible realm. Indeed, over a long and successful career his imagination has taken him on a journey through space, discovering various new and unusual celestial occurrences - notably the first successful identification of a black hole, Cygnus X-1. Paul tells Jim Al-Khalili how he spent much of his career at the Royal Greenwich Observatory, working with...

Some of the most complex medicines available today are made from living cells or organisms - these treatments are called bio-pharmaceuticals and in this episode of The Life Scientific Dr Bahija Jallal, CEO of Immunocore, shares her story of leaving her home in Casablanca, Morocco to become a world leader in developing bio-pharmaceutical cancer treatments. She tells Professor Jim Al-Khalili that she has always found herself ahead of the curve. When she began in oncology, the study of cancer,...

Reproductive science has come a long way in recent years, but there's still plenty we don't understand - particularly around male fertility. The reliability and availability of data in this field has become more of a concern in light of a study published this year, suggesting that sperm counts worldwide have dropped 62% in the past 50 years. As yet there is no clear answer as to why that is. Professor Chris Barratt is one of the scientists working to change that. He's the Head of Reproductive...

We’re used to hearing the stories of scientists who study the world as it is now but what about the study of the past - what can this tell us about our future? Gideon Henderson’s research focuses on trying to understand climate change by looking at what was happening on our planet thousands of years ago. His work has taken him all around the world - to the deepest oceans and the darkest caves - where he collects samples containing radioactive isotopes which he uses as “clocks” to date past...

If you’ve ever seen the ocean during a storm, you’ll understand the extraordinary power contained in waves. On an island nation like Britain, that power could well be harnessed to produce clean energy; so why have we barely begun to tap this bountiful resource? Deborah Greaves is trying to change that. As Professor of Ocean Engineering at the University of Plymouth, she combines physical wave tanks with sophisticated computer modelling to test how well wave power devices respond to stormy...

Erica McAlister on the bee intellect and whether bigger brains are always better. Plus cockroaches may be reviled by many people, but Erica discovers the extraordinary flexibility of their simple nervous system led to the birth of neuroendocrinology.

What are allergies and what is the purpose of them? What can we do to try and prevent them? And what are the best ways of accurately and safely diagnosing them?

Erica McAlister on the innocuous wasp-like black soldier fly, a crown jewel of a fast-growing insect farming industry that's addressing the urgent need to find cheap clean protein. And how Namib Desert beetles have evolved in a very special environment, where the only source of water exists in the air. (Image: Desert beetle in Namib desert. Credit: Martin Harvey/Getty Images)

Blowflies may be some of the most reviled insects on the planet, but as Erica McAlister discovers, they are central to the surprisingly long tradition of forensic entomology and how there's more than meets the eye in the distinctive structural colour of the morpho butterfly wing, whose dazzling sheen is a key for camouflage and commerce.

Dr Erica McAlister uncovers a treasure trove of remarkable insights from the insect world including the innocuous flies that are Drosophila melanogaster. More is known about these flies than any other animal on the planet, as a model for human genetics. And the hoverfly that arguably undergoes the biggest transformation of any animal and how insect metamorphosis could be a tool to track future climate change.

Dr Erica McAlister uncovers a treasure trove of remarkable insects from the humble flea whose jump enables them to fly without wings and the mystery of the hawkmoth’s tongue, whose varying length has offered the simplest and most effective proof of Charles Darwin's theory of natural selection in action.

Imagine a world in which your laptop or mobile device accesses the internet, not via radio waves – or WiFi – as it does today but by using light instead: LiFi. Well, that world may not be as far away as you might think. In fact, the technology is already here; and it’s thanks in large part to the engineering ingenuity of Harald Haas, Distinguished Professor of Mobile Communications and Director of the Li-Fi Research and Development Centre at the University of Strathclyde. He tells Jim...

Anne-Marie Imafidon passed her computing A-Level at the age of 11 and by 16, was accepted to the University of Oxford to study Maths and Computer Science. She's used to the 'child prodigy' label that's followed her throughout her career, but that doesn't mean she's had an easy ride. It was a combination of personal experience and the discovery that the number of women working in the STEM sectors - Science, Technology, Engineering and Mathematics - was in free-fall that inspired Anne-Marie to...

Our genes can tell us so much about us, from why we look the way we look, think the way we think, even what kind of diseases we might be likely to suffer from. But our genes aren't the whole story. There are other, complex and intriguing systems within every cell in our bodies which control which of our tens-of-thousands of genes are switched on, or off, in different parts of the body, and under different circumstances. Welcome to the fascinating world of 'epigenetics', which our guest, the...

From landslides and wildfires to floods and tornadoes, Bruce Malamud has spent his career travelling the world and studying natural hazards. Today, he is Wilson Chair of Hazard and Risk and executive director of the Institute of Hazard, Risk and Resilience at Durham University - but as he tells Jim al-Khalili, a lifelong passion for discovery has taken Bruce from volunteering with the Peace Corps in West Africa and a Fulbright Fellowship in Argentina, to fieldwork in India; not only studying...

The world around us is three-dimensional. Yet, there are materials that can be regarded as two-dimensional. They are only one layer of atoms thick and have remarkable properties that are different from their three-dimensional counterparts. Sir Andre Geim created the first-ever man-made 2D material, by isolating graphene, and is one of the pioneers in this line of research. Even beyond his Nobel Prize-winning work on graphene, he has explored new ideas in many different areas of physics...

Norwegian jazz musician Jon Larsen was having breakfast one clear spring morning when he noticed a tiny black speck land on his clean, white table. With no wind, birds or planes in sight, he wondered if it fell from space. Dust from space is not as fanciful as it sounds. Billions of microscopic meteorites, dating back to the birth of our solar system, fall onto Earth every year. But they are so tiny, hidden among the copious dust of everyday life, that scientists believe they are...

We've been building computers to think like us for years, but our ability to replicate human senses has been impossible. Until now. Evolutionary biologist and broadcaster Professor Ben Garrod, is off to meet some of the sensory innovators and technological pioneers who are developing human like-sensing technology. From skin patches that can read our sugar levels, to brain implants that could use our thoughts to control computers. This is the technology that could blur the boundary between...

We've been building computers to think like us for years, but our ability to replicate human senses has been impossible. Until now. This technological revolution is starting to profoundly change not only how we interact with the world around us, but is allowing us to see, hear, smell, taste and even touch things we never imagined possible before. An artificial intelligence revolution is super-charging sensing technology, promising us eyes with laser precision, ears that can distinguish every...

In The Evidence on the BBC World Service, Claudia Hammond will be exploring the concept of solastalgia; broadly defined as the pain or emotional suffering brought about by environmental change close to your home or cherished place. Made in collaboration with Wellcome Collection, Claudia Hammond and an expert panel examine this relatively new concept, one that might be increasingly heard about as the effects of climate change are felt. Claudia will be hearing stories of solastalgia from...
