What does caffeine do to our bodies?

Sweet, caffeinated energy drinks are in the headlines again as the UK Government says it wants to ban under 16s from buying them. Some can contain the equivalent caffeine as 2 to 4 espressos. James Betts, Professor of Metabolic Physiology at the University of Bath, explains the science behind how caffeine affects the bodies of adults and children. Earthquake scientist Dr Judith Hubbard from Cornell University in the US explains what we are learning from the magnitude 6 earthquake which hit Afghanistan this week. Professor Dan Levitin is a neuroscientist, cognitive psychologist, musician, and the third author shortlisted for the 2025 Royal Society Trivedi Book Prize. In his book ‘Music as Medicine’ he explores whether music can be harnessed to heal us. And BBC science journalist Caroline Steel brings her selection of brand new research.

Does warm weather mean more rats in UK towns and cities?

Summer heatwaves and missed bin collections have created panic in the press that rat numbers in the UK are increasing. We ask Steve Belmain, Professor of Ecology at the Natural Resources Institute at the University of Greenwich for the science. This summer Wales became the first country in the UK to ban plastic in wet wipes, with the other nations pledging they will do the same. Over the past few weeks there’s been work to remove a giant mound of them, known as ‘Wet Wipe Island’ on the Thames in west London. Marnie Chesterton has been to find out how they got there and what damage they could be doing to the river’s ecosystem. Professor Sadiah Quereshi, Chair in Modern British History at the University of Manchester explains why we should see the extinction of species as a modern, and often political phenomenon. Her book Vanished: An Unnatural History of Extinction is the second book we’re featuring from the shortlist for the 2025 Royal Society Trivedi Science Book Prize. And Lizzie Gibney, senior physics reporter at Nature brings us a round up of the news causing a stir in science circles this week.

Could solar panels in space be the energy source of the future?

As new research looks at the financial and environmental case for solar panels in space, we explore how likely the technology could be to power our future energy needs back on Earth. Marnie Chesterton hears from the author of a new study into the topic, Dr Wei He from King’s College London, and is joined by Professor Henry Snaith from Oxford University to look at the future of solar panel technology. We also hear from conservation scientist Adam Hart about his views on whether allowing trophy hunting could actually help to protect threatened species in the long term. Marnie also speaks to the author of one of the books shortlisted for the annual Royal Society Trivedi Book Prize, Simon Parkin. His book, The Forbidden Garden of Leningrad, explores the story of the botanists working at the world’s first seed bank during World War Two, and the extraordinary lengths they went to to protect the specimens they were keeping. We also hear from one of the judges of the awards, the crime writer Val McDermid. And science journalist Caroline Steel joins us to highlights the week’s most fascinating new pieces of research.

What will we be wearing in the future?

What are you wearing today? What processes, chemical and otherwise, have gone into creating the garments in your wardrobe? And how might they be improved, honed, transformed in the future? Professor of Materials & Society at UCL, Mark Miodownik, Dr Jane Wood, Lecturer at the University of Manchester and expert in textile technology, and materials scientist, writer and presenter Dr Anna Ploszajaki join Marnie Chesterton to take a closer look at possibly the most familiar materials we own, our clothes.

What’s the evidence for vaccines?

US Health Secretary Robert F Kennedy Jr announced plans this week to cancel $500 million dollars of funding for mRNA vaccine development. The research was focusing on trying to counter viruses that cause diseases such as the flu and Covid-19. Marnie Chesterton is joined by Professor Anne Willis, Director of the MRC Toxicology Unit at the University of Cambridge, to explore the claims made by The US Department of Health and Human Services that the technology “poses more risks than benefits”, and to look at the evidence behind the vaccines. We also visit the most powerful computer the UK has ever seen at the University of Bristol, and explore how the Isambard-AI supercomputer is being used to carry out groundbreaking new research. After last week’s call for our listeners to pay homage to the satirical songwriter and mathematician Tom Lehrer, who died at the age of 97, we hear a range of your brilliant musical tributes. And Marnie is joined by journalist Caroline Steel to explore the week’s fascinating scientific discoveries.

Why wasn’t the Russia mega earthquake as damaging as previous ones?

A massive 8.8 magnitude mega earthquake off Russia's east coast sent tsunami waves into Japan, Hawaii and the US west coast this week. While more than two million people across the Pacific were ordered to evacuate, there were no immediate reports of any fatalities. After recent devastating tsunamis like the ones that hit Fukushima in 2011 and the Boxing Day disaster of 2004, we speak to Environmental Seismology lecturer at University College London, Dr Stephen Hicks, to ask why this quake didn’t cause anywhere near the same amount of harm. After the Lionesses successfully defended their UEFA European Women’s Championship, Marnie Chesterton is joined by Professor of Sports Engineering at Sheffield Hallam University, Steve Haake, to looks at the role data analysis and Artificial Intelligence is now playing in football and other sports. We hear about fascinating new research from primatologist Professor Cat Hobaiter at the University of St Andrews into what we can learn about our evolution by studying how apes eat alcoholic fermented fruit. And Marnie is joined by technology broadcaster Gareth Mitchell to hear about the week’s brand new scientific discovery news, and for a musical homage to the satirical songwriter and mathematician Tom Lehrer, who died this week at the age of 97.
