  • 637 - What makes a healthy river?

    River health has captured the public imagination, particularly as overspills from sewers have been getting more attention in the media. But the condition of a river is so much more complicated than what flows into it from our water treatment systems. Agriculture, roads, how we use our drains, what we buy and even the medicines and drugs we take can all have an impact on our rivers and the plants and animals that call them home. So how are UK rivers doing? And what needs to happen to help those waterways that are drowning in pollution? Joining the BBC's Marnie Chesterton on stage at Green Man Festival in Wales to discuss all this is: Dave Johnston, team leader of environmental reporting at Natural Resources Wales, whose responsibility it is to monitor Welsh rivers. Joanne Cable, head of organisms and environment division at Cardiff University, whose focus is on biodiversity and what we at home can do to support our rivers. Simon Evans, chief executive of The Wye and Usk Foundation, who runs citizen science projects to support these two rivers local to the festival. Christian Dunn, wetland biologist at Bangor University, who is keen to explain the power of wetlands and has also done some surprising research into the river near Glastonbury Festival.

  • 636 - Why do we want to go back to the Moon?

    Two plucky spacecraft, one Russian and one Indian, are currently blasting towards the Moon’s South Pole. Both Russia’s Luna-25 and India’s Chandrayaan-3 are due to touch down next week. They’re heading to that particular region of the Moon in order to hunt for water, the presence of which could have huge implications for our further exploration of the Solar System. Victoria Gill talks to Dr Becky Smethurst, an astrophysicist at the University of Oxford, to find out more. Victoria then heads to the Lake District to witness the release of water voles into the ecosystem. Next up, Professor Lewis Griffin, a computer scientist from University College London, tells us how bad we are at distinguishing between real and deepfake voices. He then reveals what implications this might have for scams. Finally, Dr Helen Pilcher tells us all about the intriguing ways that animals can bend time. You can find out more in her book, How Nature Keeps Time.

  • 635 - Time is still ticking for the Amazon

    After decades of exploitation, time is running out for the Amazon rainforest. Eight South American nations came together this week for the first time in 14 years in an attempt to draw up a plan for a more sustainable future. The BBC’s South America correspondent Katy Watson sends us an update on the summit from Belém, Brazil. We also hear from Brazilian scientist Joice Ferreira who tells us why the Amazon is so important for the entire planet. Next up Victoria Gill finds out more about how British Sign Language is adding key scientific concepts to its dictionary in order to open up science communication to a broader community of people. There are still many words and phrases that have not yet been ‘signed’. Now did you know that the inhalers used by asthmatics emit a tiny amount of greenhouse gas with every puff? Victoria speaks to Dr Veena Aggarwal, a GP registrar and former member of Greener NHS, about whether the government’s new plan for environmentally friendly inhalers will help. Finally Victoria catches up with palaeoanthropologist Lee Berger. He’s written a book that tells a harrowing tale about his trip into a labyrinth of underground tunnels to find out more about an ancient human-like creature called Homo naledi.

  • 634 - Reality check: carbon capture and storage

    This week the UK government announced that around 100 new oil and gas licences for the North Sea will be issued. At the same time the Prime Minister said the government would back two new carbon capture and storage plants, one in Aberdeenshire and one in the Humber. Victoria Gill speaks to Angela Knight, former chief executive of Energy UK, about what this decision means for the UK’s aim of reaching net zero carbon emissions by 2050. She then discovers more about the capabilities of carbon capture and storage from Paul Fennell, a professor of clean energy at Imperial College London. Next Victoria travels to the sunnier shores of Spain where orcas have been ramming fishing boats. She speaks to one of the sailors who witnessed an attack. To find out more about the orcas’ behaviour, she interviews Dr Luke Rendell, a whale and dolphin expert from the University of St Andrews. We then move to Skomer, off the coast of West Wales. This important seabird colony has recently recorded an avian flu outbreak. Reporter Roland Pease speaks to Lisa Morgan from the Wildlife Trust for South and West Wales. To finish the show Dr Stuart Farrimond is back with the final instalment of his science of gardening series.

  • 633 - Battles with flames

    We're in the heart of summer in Europe, where extreme heat has spiralled into out-of-control wildfires across the Mediterranean, leading thousands to flee their homes. Previously on Inside Science we've looked at how and why temperatures are soaring across the globe. Now we're homing in on one of the most visible effects of that. First, BBC climate and science reporter Georgina Rannard paints a picture of the link between these fires and climate change. Next up we hear from Professor Stefan Doerr, director of the Centre for Wildfire Research at Swansea University, on whether Europe is prepared for a future where these blazes are more frequent and intense. Another effect of climate change you might have heard about this week is the potential collapse of the Gulf Stream. Georgina explains why leading researchers have reservations about the science behind that claim. We investigate a sometimes overlooked and under-reported source of pollution: particles from vehicle tyres. Dr Marc Masen from Imperial College London tells us about the impact they’re having on our health. And pollution from tyres is affecting flora and fauna too. Dr Paul Donald, senior researcher at Birdlife International, explains how vehicles on our roads have impacted wildlife in the environment. Finally, from four wheels to two wheels! Geneticist and body weight scientist Dr Giles Yeo is cycling from Land's End to John O'Groats with two glucose monitors on his arm. He tells us what he's hoping to learn.
