Discovery
An in-depth look at the most significant ideas, discoveries and trends in science, from the smallest microbe to the furthest corner of space. Podcast weekly on Mondays.
The Evidence: Is the world becoming more allergic?
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?
Metamorphosis: Soldier fly and desert beetle
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…
Metamorphosis: Blowflies and Dazzling disguise
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…
Metamorphosis: Drosophila melanogaster, hoverfly
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…
Metamorphosis: Jumping Fleas and Mighty Mouthparts
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…
Anne-Marie Imafidon
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…
Anne Ferguson-Smith
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…
The Life Scientific: Bruce Malamud
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…
The Life Scientific: Andre Geim
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…
In Search of Stardust
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 isn’t as fanciful as it sounds. Billions…
Bodies, brains and computers
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…
Remote touch
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…
The Evidence: Exploring the concept of solastalgia
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…
Smelly people
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…
Sound solutions

Sperm Counts
James Gallagher get's behind the hype to find out if sperm counts are really falling? There are plenty of headlines telling us they are, but also scientists who disagree - he unpicks the evidence with two of them. James also gets his own sperm sample analysed and meets a couple…
Psychedelics
James Gallagher reports on a psychedelic renaissance; a new wave of research testing hallucinogenic drugs like magic mushrooms to treat mental health conditions. There’s genuine excitement and some early encouraging evidence. A manufacturer tells James that in five years’ time, it’s possible that psychedelics could be part of the medicine…
Fungal Pandemic Threat
We’re familiar with fungal infections like Thrush and Athlete’s foot, but fungal diseases that can kill are on the increase. The World Health Organisation is so concerned that it’s published its first ever list of life threatening fungi. In this edition of Discovery, James Gallagher hears stories of hospitals being…
