BBC Inside Science

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 th...

CERN’s plans to build a bigger, faster particle collider, with a hefty 17 billion Euro price tag, are in question. Physicists Andrew Pontzen and Harry Cliff discuss if the new machine is really worth it. A place on the podium or disappointment in the Olympics can come down to the precise position of a foot or angle of the hips. Science reporter Ella Hubber visits the University of Bath to check ou...

Antarctica is a 'natural reserve, devoted to peace and science' - that’s according to an international treaty. But with visitor numbers at a record high, how does tourism fit into that – and what kind of impact is it having on its fragile ecosystem? We discuss whether tourists – and even scientists – should be allowed to go at all. Swimming in the Seine has been banned for more than a century beca...

We visit Wimbledon’s iconic Centre Court... but we’re not interested in the tennis, we want to know all about the grass. Just how important is science to cultivating the perfect playing surface? Also this week, we discuss the aims and ethics of human stem-cell-based embryo models in research after a new code of practice for the UK made headlines. And we answer a listener question about whether whi...

It’s election time but over here in Science Land, we’re heading off to the seaside for our summer special. We chat seagulls with Professor Paul Graham on Brighton beach and find out why they are so misunderstood - from what we call them to why they pinch our chips. We bust some sun safety myths with dermatologist Dr Jess Felton and find out why ice cream is such a chemical marvel with chef Terri M...

As another week of disruptive Just Stop Oil protests grabs media attention, sociologist Dana Fisher discusses which actions might help a cause - and which could harm it. Japanese scientists have developed artificial skin for robots made from real human cells. Inside Science producer Dr Ella Hubber digs into the uncanny invention. Inside Science reporter Patrick Hughes goes on the trail of methane...

Taylor Swift fans danced so hard they made the ground shake at her recent Edinburgh gig so this week we’re meeting Earth Scientists Emma Greenough and James Panton to measure the Cardiff show - and explain some Swiftie Seismology. We’re joined by the BBC’s disinformation and social media correspondent Marianna Spring and Cardiff University's Professor Martin Innes to talk the science of tracking e...

Elon Musk’s implanted brain chip, Neuralink, is coming to the UK for clinical trials. Is controlling computers with our minds a future reality or is it all hype? Neuroscientists Dean Burnett and Christina Maher weigh in. Zoologist Jules Howard ponders the strange effects drugs in our sewage have on frogs from his garden pond. How do we measure the distance to distant galaxies? Astrophysicist Edwar...

The looming danger of antibiotic resistance may have fallen out of the public consciousness but is still very much in the mind of those in public healthcare and research. As promising new research is published, the University of Birmingham’s Laura Piddock and GP Margaret McCartney get to the bottom of why antibiotic resistance is still so difficult to tackle. Marine biologist Helen Scales joins us...

Guest presented by Liz Bonnin. We all instinctively know that sleep is incredibly important but science doesn’t actually have a satisfying answer for why we need to sleep. There are multiple theories, but now, new research from Imperial College London has suggested that the leading idea might actually be incorrect. Science journalist Ginny Smith explains. Nearly 80 years ago, one of the rarest ele...

Guest presented by Liz Bonnin. As the UK strives to achieve net zero by 2050, nuclear energy is looking more and more likely as a key player in reaching this goal. But it’s not just massive power plants like Hinkley point C - there’s are newer smaller reactors on the scene: small and micro modular reactors. 100 to 1000 times smaller than a conventional reactor, faster to build, and put together en...

Last week, a girl who was born deaf had her hearing restored following gene therapy. In the US, the first commercial gene therapy for sickle cell disease has just begun. And Great Ormond Street Hospital has found great success in their trials and a gene therapy for children lacking an immune system. Gene therapy is clearly having a moment. But how do these groundbreaking therapies actually work? A...

There has been increasing public outrage at raw sewage discharges into our rivers and seas, but new research at Lake Windermere suggests that treated sewage is as much to blame. Wastewater experts Simon Evans and Ali Morse get into the nitty gritty of sewage treatment and why it might be causing so many problems. Last week, the Sumatran orangutan Rakus made headlines when he was spotted by researc...

One year ago, the World Health Organisation declared that COVID-19 would no longer be categorised as a global health emergency. But the pandemic has left us with a new normal in all areas of our lives. From vaccine rollout to wastewater monitoring, we’re asking: how has COVID altered the scientific landscape? Marnie Chesterton is joined in the studio by Linda Geddes, science journalist, and Barbar...

As the UN tries to get a global agreement on plastic waste we hear from two delegates at the conference in Ottawa; John Chweya, a Kenyan waste picker, and plastics scientist, Steve Fletcher, discuss the impacts of plastic pollution and the possible solutions. Taylor Swift’s new album, The Tortured Poets Department, exposes the pain a break up can cause. Heartbreak is a common theme in music and ar...

Earlier this week, some of the world's leading astrophysicists came together at The Royal Society to question the very nature of our Universe. Does the Lambda Cold Dark Matter model, which explains the evolution of the cosmos and the Big Bang, need a rethink? Dr Chris North, an astrophysicist from the University of Cardiff, joins us in the studio to explain what this model says, and why it might n...

A strain of highly pathogenic bird flu, H5N1, has been spreading unchecked through wild bird, and some mammal, populations for the past few years. Last week, news of a large number of dairy cows in the USA being infected with bird flu has alarmed the public and virologists alike. One farm worker has also picked up the virus and although they are not seriously ill, the jump between cattle and human...

In 1824, 200 years ago, Megalosaurus was the first dinosaur to ever be described in a scientific paper. William Buckland studied fossils from Stonesfield in Oxfordshire in order to describe the animal. In this episode, Victoria Gill visits palaeontologist Dr Emma Nicholls at the Oxford University Museum of Natural History, who shows her those very fossils that launched the new science of palaeonto...

Microbiomes are a multi-million-pound industry. Every week, many people send off poop samples to be examined so we can learn about our own ecosystems of bacteria, virus and fungi that live in our guts, with a view to improving health. But how accurate are these tests? Microbiologist Prof Jacques Ravel is calling for better controls in what is currently an unregulated industry. He joins us along wi...

Professor and presenter, Chris Lintott, talks about his new book Our Accidental Universe; a tour of chance encounters and human error in pursuit of asteroids, pulsars, radio waves, new stars and alien life. Even with incredible technological developments, the major astronomical events of the past century are largely down to plain ol’ good luck; discovered not, as you might assume, by careful exper...

The world’s oldest fossilised forest was uncovered in Somerset last week. We head to palaeobotanist, Dr Christopher Berry’s, lab at Cardiff University to learn about these cladoxylopsids. They lived 390 million years ago and although they are not the ancestors of today’s trees, they reveal some extraordinary evolutionary secrets. Also, Marnie speaks to Dr Chris Thorogood of the University of Oxfor...

A recent study on how to get rid of microplastics in water sparked presenter Marnie Chesterton’s curiosity. When she turns on the tap in her kitchen each day, what comes out is drinkable, clean water. But where did it come from, and what’s in it? Dr Stewart Husband from Sheffield University answers this and more, including listener questions from around the UK. Is water sterile? Should I use a fil...

Switzerland has submitted a proposal to create a United Nations expert group on solar geoengineering to inform governments and stakeholders. The idea was discussed at the UN Environment Assembly in Nairobi, Kenya, this week. Professor Aarti Gupta shares how, after tense negotiations, the different member states could not agree, and the proposal was withdrawn. Why is solar geoengineering a controve...

Professor Ben Garrod guest presents. As a new 'meaty rice' is created and Fortnum & Mason launch a scotch egg made with cultivated meat that they hope to have on sale as early as next year, we investigate the world of laboratory-grown meat. Mark Post made the first ever synthetic meat in 2012 to the tune of £200,000. He tells us how these lab-grown meats are made and how, he thinks, they could...

The Gulf Stream, also known as the Atlantic Meridional Overturning Circulation (AMOC), is essential to stable global climate, and the reason we have moderate temperatures in Northern Europe. Now, a new modelling study suggests that this circulation could, at some point, be at a tipping point and collapse. We hear from one of the minds behind the model, post-doctoral researcher René van Westen from...
