  • Buried Mars Landers, Freezing Species, and Low-Tide Archaeology

    16/06/2022 Duration: 28min

    Since 2018, Nasa's InSight Mars lander has been sitting on the surface listening to the seismic rumbles of the red planet's deep interior. But this week, plans were announced to finally phase down its activity, as martian dust obscures too much of its solar panels to power it through the forthcoming winter. Jon Amos tells Vic Gill of some of its many successes, and quite why it didn't fly with a duster on board. 50 years of observations across Australia's northern tropical forests suggest yet more bad news for the climate. Trees’ mortality has, it seems, doubled since the 1980s. As Oxford University's David Bauman tells Vic, it seems to be linked to a drying of the air as temperatures rise, and if the trend is also true across the world's other moist tropical forests, they could rapidly slip from being carbon sinks, to carbon sources.Conservationists say we’re losing animal species faster today than at any point in the last 10 million years of Earth’s history. And one approach aims to save as many of those lo

  • Running Rings Around Matter

    09/06/2022 Duration: 28min

    Astronomers have captured the first image of Sagittarius A*, the gargantuan black hole at the centre of our galaxy. Dr Ziri Younsi, University College London, shares what it took to capture a picture of a supermassive black hole that is 26,000 light-years away and from which (almost) nothing, not even light, can escape. The world’s largest and most powerful particle accelerator, the Large Hadron Collider, is restarting after three years of upgrades. Roland Pease visits the European Particle Physics Laboratory, CERN, to see how things are going, and looks back on some of the team's past successes. Also, how do you investigate the mysterious deaths of the world’s biggest fish when their bodies sink without trace? That’s the quandary facing marine scientists who’ve been trying to figure out what exactly is killing whale sharks. Freya Womersley, UK Marine Biological Association, shares how satellite tracking technology is helping us solve the mystery.And finally, what’s in a name? As our inventory of Earth’s bio

  • Precious Metals, Earlier Eggs, and Meaningful Meteorites

    02/06/2022 Duration: 32min

    With the cost of living spiralling, many are probably thinking more about the price of food than lithium, titanium, copper or platinum. But the volatility in the global market for these materials - partly because of the pandemic and geopolitical unrest - is causing 'chaos' in the technology supply chain. Elizabeth Ratcliffe, Royal Society of Chemistry, tells Vic that many of us are unwittingly stockpiling these precious metals in our homes, in our old phones and defunct computers, because we don't know what to do with them. Reporter Samara Linton visits N2S, a company in Bury St Edmunds which has found a way to recycle the precious metals and other scarce elements in discarded circuit boards using bacteria. This week more evidence that spring is springing earlier, as Vic heads to what might be the most studied woodland in the world: Wytham Woods in Oxfordshire. Ella Cole, Oxford University, explains how climate change is causing birds to lay eggs three weeks earlier than they did in the 1940s. And Chris Perr

  • The Ebb and Flow of the Tidal Power Revolution

    26/05/2022 Duration: 43min

    This week, we begin with a disturbing medical mystery. Since the start of the year, almost 200 children worldwide have fallen ill with hepatitis—or liver inflammation—without any apparent cause. Most of the children are under five, and nearly half of the cases were in the UK. Vic Gill asks clinical epidemiologist Deepti Gurdasani, Queen Mary University of London, what we do and don't know about these rare cases.Also on the programme, with a huge tidal range, Wales and the west coast of England have become the focal point for a new generation of tidal power plans. So, is the tidal energy revolution finally happening? Roger Falconer, Emeritus Professor of Water and Environmental Engineering at Cardiff University, and Andrew Scott, CEO of Orbital Marine Power, which has demonstrated a working tidal stream turbine - called O2 - off Orkney, share their insights.And fancy eating an insect burger? Or how about adding seaweed smoothies or mycoprotein meatballs to your diet? Fellow BBC science correspondent Helen Brig

  • Building Better Engagement

    19/05/2022 Duration: 34min

    Victoria Gill and guests ask why does scientific communication matters in society and how it might be done better, with Sam Illingworth, Berry Billingsley and Ozmala Ismail.The climate crisis and Covid-19 have shown over the recent years the importance of reliable, relatable, transparent and trusted science communication. But just like science itself, it comes in different forms and takes different approaches. Always keen to keep you up to date, BBC Inside Science takes a moment to discuss good practice and how it might be done better. Dr Oz Ismail is a dementia researcher who also finds time to do stand-up, public engagement and a podcast called Why Aren’t You A Doctor Yet?Sam Illingworth is an Associate Professor at Edinburgh Napier University who investigates science and communication between disciplines. He is also a poet and writer, and has a podcast called The Poetry of Science.And Berry Billingsley is Professor in Science Education at Canterbury Christchurch University. Erstwhile science broadcaster, s

  • A Trip-Switch for Depression?

    12/05/2022 Duration: 35min

    Could magic mushrooms be the key to a revolution in treating depression? Professor David Nutt, director of the Imperial Centre for Psychedelic Research, thinks so. He tells Vic Gill about recent research suggesting that psilocybin - the psychedelic compound found in magic mushrooms - triggers rewiring of the brain in people with treatment-resistant depression. Vic Gill speaks with trial participant Steve Shorney who was diagnosed with depression 30 years ago. Nanobodies. That's the name scientists have given to the tiny antibodies found in the blood of camelids like llamas, alpacas and camels. Reporter Samara Linton heads to Berkshire to meet the llamas whose nanobodies were recently found to neutralise the Covid-19 virus. We hear from Professor Gary Stephens, University of Reading, who is responsible for the llamas' safety and well-being, and Professor James Naismith, director of the Rosalind Franklin Institute which is carrying out the pioneering research with engineered nanobodies. And just as the James

  • Declining Data, Climate Deadlines and the Day the Dinosaurs Died

    05/05/2022 Duration: 36min

    Covid-19 infections in the UK are at an all-time high. But most people in England can no longer access free Covid-19 tests, and the REACT-1 study, which has been testing more than 100,000 individuals since the pandemic began, ended last week after its funding stopped. Martin Mckee, Prof of European Health at the London School of Hygiene and Tropical Medicine, shares his insights on what these changes might mean for ambitions to 'live with the virus'. This week, the UN's latest Intergovernmental Panel on Climate Change (IPCC) report has unveiled a to-do list of ways to save the planet from climate catastrophe. How do scientists reach a global consensus on climate change amid war, an energy crisis, and a pandemic? Vic Gill speaks to report co-author Jo House, University of Bristol, and Ukrainian climate scientist Svitlana Krakovska who took part in signing off every line of the report while sheltering from the war in Kyiv. And from our planet's present and future to its ancient past. Scientists working on the

  • How can the UK get to zero carbon?

    28/04/2022 Duration: 27min

    Energy is essential: every living thing needs energy to survive, and today’s industrialised societies consume enormous quantities of it. At the moment, the vast majority of this comes from burning fossil fuels that emit carbon. But the government is committed to reaching net zero carbon emissions by 2050. Meanwhile, oil and gas prices are rocketing, exacerbated by the ongoing war in Ukraine. And the energy price cap is being raised on April 1st, hitting millions of householders in the UK. While we await the government’s energy strategy, Inside Science looks at how to solve the problem, finding the best possible ways to meet our energy needs while slashing our carbon emissions. Joining us to discuss this are Alice Bell, co-director of the climate charity Possible, and Jan Rosenow, director at the Regulatory Assistance Project. We also hear from Chris Stark of the Climate Change Commission on how the government might meet its decarbonisation targets, visit a Cornish field that might be a rich source of homegro

  • Racial inequality in UK science

    21/04/2022 Duration: 32min

    This month the Royal Society of Chemistry released a shocking report on racial inequality at all stages of academia, from research funding to career progression. Black scientists in particular are unfairly disadvantaged when it comes to funding allocation. This is bad for them, bad for science, and bad for society. So how do we change things? Dr Diego Baptista from the Wellcome Trust, Professor Melanie Welham from the UKRI, and Dr Addy Adelaine, from the non-profit organisation Ladders4Action, join us to discuss the issue. Both of Earth’s poles were hit by heatwaves this week. The Arctic was 30 degrees above average for this time of year, and the Antarctic was an unprecedented 40 degrees above average. We are seeing more extreme temperatures everywhere on earth, but for both poles to experience such heatwaves at the same time is highly unusual. Ed Blockley of the Met Office’s Polar Climate Group explains what’s going on. One of the simplest ways to improve your local environment is to plant a hedge, which no

  • Global food security during Ukraine conflict

    14/04/2022 Duration: 28min

    The Russian conflict in Ukraine is already causing hunger there, and as Ukraine and Russia are huge grain exporters, the crisis will be far reaching. Food prices everywhere are expected to rise, and there’s fear that the war could affect food supplies in some of the poorest parts of the world. Tim Lang, Emeritus Professor of Food Policy at City University of London, and Dr Hannah Ritchie, Head of Research at the website Our World in Data, join us to discuss food security. Lead is highly toxic to humans and other animals. One source of lead in the environment is the bullets and shot used to hunt wild game, and new research shows that lead shot has a significant effect on birds of prey such as eagles, buzzards and vultures across the whole of Europe. One of the study’s authors, Professor Debbie Pain, explains the research. Many of us have spent the past two years anxiously following Covid graphs, but from next month the government is cutting funding to several surveillance programmes. Mass free testing will als

  • High Seas treaty talks and discoveries from the deep

    07/04/2022 Duration: 28min

    The High Seas make up most of our oceans but belong to no-one and are largely unregulated, leaving them at risk of plunder. UN talks start afresh this week with the aim of protecting the marine biodiversity of these vast swathes of living ocean. Covid-19 can shrink our brains and lead to cognitive decline, even in mild cases, according to a new study out this week. Professor Gwenaëlle Douaud, who led the research, explains how they used hundreds of brain scans to discover the effects of Covid infection. A completely different discovery this week was made at the bottom of the sea; we hear how, after 107 years, scientists have finally found The Endurance, the lost shipwreck of Antarctic explorer Sir Ernest Shackleton. How might the Russian invasion of Ukraine affect international space exploration? After a Twitter spat between a former NASA astronaut and the Russian space chief, we’re joined by BBC science correspondent Jonathan Amos and BBC Russian’s Nikolay Voronin to discuss how science in Russia and the res

  • Cyber frontlines in Ukraine

    31/03/2022 Duration: 28min

    As conflict continues in Ukraine, there are invisible ‘cyber frontlines’ running in parallel to the physical fighting. We hear how the country’s tech scene is responding to the Russian invasion, as Mike Sapiton, Tech Editor at Forbes Ukraine gives us a view from the ground, and Professor Madeline Carr explains why cyber warfare can be particularly dangerous. A major report published this week speaks to a different kind of crisis: climate change. There are stark warnings for humanity and the planet, with the Intergovernmental Panel on Climate Change assessing the impacts of global heating on people and places, as well as how we can adapt to a drastically changed world. One of its lead authors, Professor Richard Betts, reflects on the report. Russia is one of the world's biggest producers of coal, gas and oil, so what might their invasion of Ukraine, and the ensuing sanctions, mean for global energy supplies? Simon Evans, deputy editor of the climate website Carbon Brief, discusses whether we're more likely to

  • World’s largest Jurassic pterosaur found on Skye

    24/02/2022 Duration: 28min

    In a week of exciting fossils finds we get up close to a 170 million year old pterosaur, found on the Isle of Skye. And over in the States, some fossilised fish hold the clue to what time of year the dinosaurs, along with three quarters of life on Earth, met their end. We hear from researcher Melanie During who tells us how growth patterns in sturgeons' bones reveal the season of this mass extinction.Predictions for how our climate will change over the coming years are essential in setting and meeting emissions targets, however human behaviour is usually left out of climate model equations. Fran Moore and Katherine Lacasse explain why and how they factor public opinion, habits and political trends into their climate model. And finally, why is it so important we clean up after our pets? Dog poo is incredibly nutrient rich, and Professor Pieter de Frenne has been looking into the surprising negative effect any waste left behind can have on woodland and nature reserves. Presented by Marnie Chesterton Producer

  • COVID-19: Beginnings... and endings?

    17/02/2022 Duration: 32min

    With the prime minister proposing an end to self-isolation requirements as early as the end of the month, we thought we would check in with all things pandemic-related this week. We hear from mathematical biologist Dr Kit Yates from the University of Bath and UCL’s Professor Christina Pagel, who, like many scientists, are concerned about the consequences of relaxing protective measures. However, epidemiologist Professor Irene Petersen tells us why she feels it is the right time to loosen restrictions. A new omicron sub-variant has been making headlines this week. Professor David Male takes us through what we know about omicron BA.2 so far. And from possible endings to the pandemic’s origin story. Roland Pease spoke to Beijing-based journalist Jane Qiu who’s gained unprecedented access to the Wuhan scientist at the centre of lab leak theories.Presented by Marnie Chesterton Producer Samara Linton Assistant Producer Emily Bird Made in association with The Open University

  • Fusion energy smashes world record

    10/02/2022 Duration: 28min

    This week the UK-based JET Laboratory broke its 25-year-old record for energy extracted by nuclear fusion - the process that powers the stars. Using temperatures 10 times hotter than the sun, nuclear fusion has the potential to provide vast amounts of energy at a very low carbon cost. But re-creating the power of the stars here on earth is no easy feat, and Roland Pease has been in Culham, speaking to the scientists at the forefront of this breakthrough.We discuss the Advanced Research and Invention Agency ( ARIA. The ARIA bill is about to go through the final stages of parliamentary approval and will have a budget of £800 million to play with over four years. But it’s not without its critics. Many in the science community have questioned ARIA’s transparency and accountability to the public, because the government have decided to exempt ARIA from Freedom of Information Requests. We hear from UKRI head Professor Dame Ottoline Leyser and Professor of Research Policy James Wilsdon. And from blue skies research t

  • The Continuing Story of the Nuclear Waste Bill

    03/02/2022 Duration: 36min

    Whilst energy prices are shooting up due to gas demand, in the UK the plans for the next generation nuclear reactors are moving ahead. The costs of eventually decommissioning these, and the spent fuel products they will create is all part of the new contract. But what is to be done, and how far have we got with the 70 years of legacy waste piling up in the UK? Claire Corkhill of Sheffield university helps advise the government about nuclear waste disposal. As she tells Marnie, it's a long-term problem that must be dealt with some day, and even future nuclear fusion plants will have radioactive parts when they need replacing.You may feel that spring seems to come earlier each year. Ulf Buntgen and colleagues at the University of Cambridge have been using data from "Nature's Catalogue", a database of observations going back as far as the c18 to determine the dates each year that certain species of UK native plants first flower. And they have found a clear signal that plants are indeed flowering earlier due to c

  • Predicting Long Covid, and the Global Toll of Antimicrobial Resistance

    27/01/2022 Duration: 36min

    Prof Onur Boyman, Director of department of Immunology at University Hospital, Zurich, this week published a paper in the journal Nature Communications that presents a way of quantifying the risk of a Covid patient going on to develop Long Covid (or PACS as some call it) based on certain symptoms, but crucially also two key biomarkers in the blood. As he explains to Gaia, combining the levels in the blood of two key immunoglobulins (IgM and IgG3) with other pointers, first identified last year, allowed him and his team to make successful predictions as to the relative likelihood his sample group of patients might go on to still be exhibiting symptoms beyond four weeks after infection. Asthma is of particular interest to these researchers, partly because it can share this blood signal of Ig markers. Might it even also shed any light on things such as Chronic Fatigue Syndrome?Dr Claire Steves, of Kings College London, whose previous work on symptom gathering Onur's team have built upon, agrees this is a promisi

  • The 'perfect' depth for a destructive eruption

    20/01/2022 Duration: 37min

    Why was the blast from the Hunga-Tonga-Hunga-Ha'apai volcano so explosive? Where are we on the global climatic thermostat? And how you can get involved in the Big Repair Project.Gaia Vince speaks with Auckland University volcanologist Prof Shane Cronin, one of the few human beings to have visited the now-disappeared volcanic land bridge that stretched until last week between the islands of Hunga-Tonga and Hunga-Ha'apai. It was destroyed in the disastrous eruption of the volcano beneath it last week that has wrought such devastation to the nation of Tonga, and whose effects were felt in the Americas and detectable all around the world. Why was this submarine eruption quite so explosive, given that the eruption itself was not one of the biggest or longest in living memory?Previous eruptions - notably Mount Pinatubo in the Philippines in 1991 - released huge amounts of particles and sulphates into the stratosphere such that they had a cooling effect on the atmosphere globally, lasting 2-3 years. Prof Richard Bet

  • The Rutland ‘Sea Dragon’, An Astronomer's Christmas and some Animal Magic

    13/01/2022 Duration: 28min

    After 20 years of planning, preparation and a nail-biting build up fraught by delays The James Webb Space telescope finally launched on Christmas day 2021. Anxious astronomers across the globe looked on as the JWST then completed even riskier manoeuvres to unfurl the 18 hexagonal components that make up its 6.5 meter diameter primary mirror. Cosmologist Dr Sheona Urquhart from the Open University tells us about the astronomical community’s tense Christmas day. Fresh from a TV spot on BBC Two’s Digging for Britain this week, Dr Dean Lomax and PhD candidate Emily Swaby share their excitement unearthing Rutland’s ‘Sea Dragon’ and explore what this find could tell us about Ichthyosaurs. At over 10 meters long this ancient ocean predator is the largest complete fossil of its kind to be discovered in the UK. Ichthyosaurs are commonly associated with Dorset and Yorkshire coastlines where fossils are often revealed as surrounding rock is eroded by the elements. Finding an ichthyosaur fossil inland is unusual but not
