BBC Radio 4


A weekly programme that illuminates the mysteries and challenges the controversies behind the science that's changing our world.


BBC Inside Science

A shortage of medical isotopes used to detect cancer has experts concerned that the shortfall could be delaying diagnosis and could even be costing lives. 

Exactly what these nuclear medicines are and how they are made is key to understanding the national scarcity. So, we’re going back to basics and learning all about medical isotopes. 

We also speak to world-famous conservationist and primatologist Jane Goodall who, now aged 90, continues to travel the globe campaigning to protect the natural world. 

Dame Goodall reflects on a life of studying our closest living animal relatives, chimpanzees, and as COP29 gets under way, speaks about the “closing window of time” to turn the tide on climate change and nature loss. 

Also this week, we answer the listener question “Why don’t we just throw nuclear waste into volcanoes?” and can Marnie spot AI vs real poetry?

Nuclear medicine shortages and Jane Goodall on COP29

As conflicts in the Middle East and Ukraine continue to dominate the news, many Inside Science listeners have been in touch with the same question: 

What is the carbon footprint of war? 

How significant is the impact – and is it crass to even talk about it? We’re joined by Benjamin Neimark from Queen Mary University in London. 

Also this week, we chat to the incoming DG of Europe’s particle-smashing facility Cern, what have we learnt by defrosting an extinct big cat and, the beetle that could ruin Christmas...

The climate cost of war

The south Wales town of Pontypridd saw cars submerged, people bailing floodwater out of their homes using bins, and the beautiful park and lido transformed into a brown mess, as parts of the UK were flooded. 

But, it's nothing new. Pontypridd was severely flooded just four and a half years ago – and these are scenes that play out around the UK every winter. 

So, is the way we warn people about floods failing? 

We’re going to unpick exactly how floods are forecast – and what went wrong – with natural hazards researcher and hydrologist, Professor Hannah Cloke. 

Also this week, sharing your microbiome with friends, alternative plastics, and was the most recent climate summit good COP or bad COP?

Is flood forecasting failing?

Some social media users have been pouring milk down the drain and chucking their butter in the bin in protest over a new additive in cow feed that claims to reduce methane emissions. 

The online posts, attacking Arla Food’s trial of Bovaer with three big supermarkets and 30 farms in the UK, have had millions of views. 

So, what do we know – what is this additive and how is it going to tackle burpy cows? And what is the evidence it is safe? 

We interrogate the science with Sharon Huws, professor in animal science, and food scientist Dr Stuart Farrimond... 

Also this week, are billionaires really deserting Earth for space? What is the upshot for our plastic waste problem after global talks on a treaty ended in failure? And why, just why, are orcas being spotted wearing salmon hats?

Fact-checking the Bovaer backlash

More species infected than ever, an uptick in human cases, and some concerning biological modifications. How close are we to a bird flu pandemic? 

We digest the last year of bird flu changes with virologist Tom Peacock and public health journalist Melody Schreiber. 

Also this week, we address the absurd problem of transporting something that can't be touched, we find out how animals make their epic migratory journeys, and Victoria Gill visits a town which has learnt to ward off a fearsome predator, polar bears.

The rising threat of bird flu

We look back on 2024 in science, from billionaires in space, to record-breaking heat here on Earth, and the meteoric rise of new weight-loss drugs. 

From the biggest stories to the unsung and the plain fun, Inside Science presenter Victoria Gill hosts a special panel, featuring: 

- Libby Jackson, head of space exploration at the UK Space Agency 
- Penny Sarchet, managing editor of New Scientist 
- Mark Miodownik, a materials scientist from University College London

The Year in Science

It’s that time of the year when many of us are at home with friends and family, losing track of time, eating leftovers, and, of course, playing games. 

This festive season, we look at the science of games and, of course, play some ourselves. 

It’s presenter Marnie Chesterton versus producer Florian Bohr at Marnie's kitchen table.... Who will win the Inside Science games special?

Irving Finkel from the British Museum tells Marnie about the Royal Game of Ur, one of the most ancient board games which is strikingly similar to more modern examples of race games. Also, why we play games with author and neuroscientist Kelly Clancy, and why we struggle to comprehend the randomness of dice with author Tim Clare. 

To finish it off, mathematician Marcus du Sautory explains the geometry behind the game Dobble and leaves listeners with a Christmas puzzle: Can you figure out the symbols on the two missing Dobble cards?

Board Game Science

Why do we laugh more when we’re with others? Are humans the only animals that laugh? Does ‘laughter yoga’ actually do anything? We're delving into the neurobiology, evolutionary history, and health effects of a good old chuckle.

Live from the Hay Festival Winter Weekend, Marnie Chesterton is joined by laughter expert and neuroscientist, Professor Sophie Scott, and an expert in making people laugh, comedian Miles Jupp, in this side-splitting panel show.

Science in 2025

It’s the biggest story of recent weeks. Literally. 

Trillion-tonne iceberg A23a is on the move. But where is it headed and why – and what might it mean for the scientists and penguins in its path? 

And from a giant ‘megaberg’ to a giant pile of highly radioactive material, we find out what locking away a load of radioactive waste has in common with baking a cake. 

And we’re joined by science journalist Caroline Steel to guide us through this week’s science news. 

We’ll hear about the first study into whether banning phones in schools works, why scratching an itch might have benefits beyond just satisfaction, and the perfect formula to boil an egg... 

Presenter: Victoria Gill 
Producers: Sophie Ormiston, Ilan Goodman & Gerry Holt 
Editor: Martin Smith 
Production Co-ordinators: Jana Bennett-Holesworth & Josie Hardy

Science-backed boiled egg recipe:

- You need two pans… and exactly 32 minutes
- Keep one pan at 100 degrees Celsius (boiling) and the other pan at 30 degrees Celsius
- Move the egg between the two every two minutes for 32 minutes

Enjoy!

The World’s Biggest Iceberg

Space junk. 

It might sound like an out-of-this-world problem that we don’t need to worry about here on Earth – but is it? 

As we send more and more metal in the form of satellites up into space, scientists are warning it is becoming more of a risk both here – and up there. 

We dig into the problem and what’s being done to clean it up. 

Also this week, we answer a listener question about oceans and their influence on global temperatures, and we ponder the use – and sometimes abuse – of scientific language. 

And with the Paris Olympics well under way, how much does sex affect sporting performance? 

Presenter: Victoria Gill 
Producers: Ella Hubber & Gerry Holt 
Editor: Martin Smith 
Production Co-ordinator: Jana Bennett-Holesworth

How much of a risk is space junk?
