Twenty years ago this week two physicists at the University of Manchester published a ground-breaking paper describing the extraordinary qualities of graphene. The thinnest and strongest material known to exist – and better at carrying electricity than any metal – its discovery was hailed as revolutionary. But two decades on, it doesn’t seem to have changed the world, or if it has, it is doing so very quietly. So, what happened? We go on the trail of graphene, meeting Nobel Prize winner and Godfather of Graphene Andrew Geim, and learning what it has – and hasn’t – done and what might be next... Also this week, how to kill an asteroid and we talk the “other” COP with chief scientific adviser to the government, Dame Angela McLean.

“That’s the end of coal in the UK for electricity.” The UK’s last coal-fired power station has closed, ending Britain's 142-year reliance on coal. But what difference will the closure of Ratcliffe-on-Soar make – and could it mark a new dawn for clean energy? After 20 years of research into microplastics and headline upon headline on their potential harms, how much do we really know about these tiny particles? Also this week, Marnie turns lab rat for a navigation experiment, and why are we all so obsessed with Moo Deng?

The images beamed back to Earth of the first civilian spacewalk have prompted a very pertinent question from one Inside Science listener: What effect is space travel having on our climate? We're used to delving into the carbon footprint of Earth-bound travel – so this week we’re going to explore the impact of the rapidly growing space industry on our climate. How does a rocket launch compare to a flight taking off? Do we even know the true cost yet – and if it’s significant, what might the solution be? Also on the programme, a personal perspective from a remote island on worrying seabird declines, the results of a project to refreeze Arctic sea ice, and why new evidence unearthed about the Falkland Islands suggests it may once have looked very different...

Lab-grown meat, cultivated meat, cultured meat, in-vitro meat - whatever you call it, the industry claims it could be a game changer. Not just economically, but for feeding the planet in a sustainable way. But is it too good to be true? And will people even eat it? In this special episode of Inside Science, we take a deep-dive into lab-grown meat; visiting a production facility to see how it's made, hearing about the nuanced perspectives of British farmers, asking if this new industry can learn from the failings of GM foods, and trying to figure out what the true environmental costs of entirely new way of producing food really is. Presenter: Victoria Gill Producer: Ella Hubber Editor: Martin Smith Production Co-ordinator: Andrew Rhys Lewis

Today incredible images were beamed around the world of civilians walking in space – for the very first time. All eyes were on businessman Jared Isaacman and engineer Sarah Gillis as they ventured outside a Space X capsule. But is this an historic space exploration milestone - or just a very exciting holiday for a billionaire? We'll find out more from the BBC’s own expert space-watcher Jonathan Amos. Also this week, we visit Sellafield which processes and stores more radioactive material per square metre than any other site in Europe. But it is getting full. So where is our nuclear waste going to go in future? As the UK searches for a new potential site, we look at the science of what we do with nuclear waste and why. We’ll also delve into the fascinating world of nuclear semiotics. How can we communicate the dangers of nuclear waste to people living 100,000 years from now?

He tells us how statistics impact every aspect of our lives, and joins Marnie as a studio guest throughout the show. A drug – lecanemab – that can slow the progression of Alzheimer’s disease has recently been approved for use in the UK, but the healthcare regulator NICE has said that it won’t be available on the NHS. But what is behind this decision, and what makes creating an Alzheimer’s drug so difficult? Professor Tara Spires-Jones from the University of Edinburgh talks us through the science. And could ‘smart paint’ supersize our fruit and veg? Reporter Roland Pease heads over to the experimental greenhouses of Cranfield University’s crop science unit to see if the technology works. Thee Paralympic Games are now underway in Paris, with athletes competing across 22 different events. But as competitors have a range of different impairments, how is it ensured that there's a level playing field? Professor Sean Tweedy from the University of Queensland calls in from Paris to explain how athletes are sorted into categories for competition.

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?

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 because of pollution concerns. The main culprit? Human waste. We find out if it really will be safe in time. And every summer we ready ourselves for 'flying ant day' – that one day where winged ants take to the skies across Britain. Or do they?
