Heatwave: the consequences
The severity of last week's heatwave is changing the narrative. Gaia Vince talks to Simon Evans, deputy editor of the climate publication Carbon Brief, who has been following the media coverage of this heatwave, and Lorraine Whitmarsh, professor of environmental psychology at the university of Bath. What has the recent hot weather done to the plants in our gardens, and the crops in our fields? Dr Nicola Cannon from the Royal Agricultural University in Cirencester tells us the low-down. Expect your potatoes to get more expensive this autumn. The RHS want to know about how the heatwave has affected YOUR garden. You can help science by answering on this survey https://www.surveymonkey.co.uk/r/NVNH5FN What if we could use all the excess heat from summer, and store it to heat our homes in winter. It's something a team in the Netherlands and Austria have been looking at, using a thermochemical battery. Wim van Helden from AEE Institute in Gleisdorf in Austria explains how they made a prototype, and what the stumbling blocks are to widespread use of their system.Is this thermal battery the holy grail of heat supply? We run it, and other options, past Michael de Podestra. An ex-measurement scientist at the National Physics Laboratory until his retirement two years ago, he has since become an expert in retrofitting his house to try and make it carbon-neutral.
Multiverses, melting glaciers and what you can tell from the noise of someone peeing
The Multiverse Laura Mersini-Houghton is an internationally renowned cosmologist and theoretical physicist and one of the world's leading experts on the multiverse and the origins of the universe. She talks to Gaia Vince about finding evidence that supports her multiverse theory as more than just a hypothetical collection of diverse universes, including the one that houses our planet. She also shares her story of growing up with the horrors of a brutal Albanian communist regime.Glacier Collapse In Italy this month eleven people were killed when Marmolada glacier collapsed. A few days later, hikers recorded another huge glacier collapse in Kyrgyzstan. Is there any way of monitoring glaciers to give us a warning of these events? Glaciologist Liam Taylor, a researcher at Leeds University explains to Gaia our options for monitoring vulnerable glaciers, and why a black spot in those observations is about to open up.Pees and queues. Lower urinary tract symptoms are common and affect an estimated 60% of men and 57% of women. These can be detected using a gadget called a uroflowmetre, but patients often face delays getting to clinics to use one. Dr Lee Han Jie and Professor Ng Lay Guat, with colleagues at Singapore General Hospital and the Singapore University of Technology and Design have developed an artificial intelligence algorithm that is trained to listen to patients pass urine. From just the noise of peeing, the AI is able to identify abnormal flows and could be a useful and cost-effective means of monitoring and managing urology patients at home. Heatwave Records Richard Betts from the Met Office explains why the official highest temperature is only 40.3C, whereas many of us have clocked temperature in the mid forties in our cars and on patios.
Deep Space and the Deep Sea - 40 years of the International Whaling Moratorium.
The James Webb Space Telescope is finally in business - what further treasures will it find? Also, the origins of the International Moratorium on Whaling, 40 years old this month.This week NASA invited President Joe Biden to help them publish the first of five images of full scientific value from the newest super telescope now operating a million miles away from us. It is capable of gazing as far deep into the sky as humans have ever gazed. That first image, an upgrade of one of the Hubble Telescope's "Deep Field" shots from some years ago, shows some of the oldest matter ever seen, including light distorted into smudges and whorls by the gravitational field of galaxies in line of sight from us, much nearer and younger than the light being bent around them.The other images show even more of what the telescope is capable of seeing. Dr. Stefanie Milam of Nasa's Goddard Space Flight Centre in Maryland, US and BBC Science correspondent Jonathan Amos talk to Gaia about this new, exciting phase in astronomy.This month marks 40 years since the International Whaling Commission decided to pursue a moratorium on commercial whaling. Many whales are still struggling, but scientists have seen several species recover since then. The moratorium followed campaigning in the 1970s by such groups as Greenpeace, and even the commercial success of audio recordings of humpback whales, released by Drs. Roger and Katy Payne. Greenpeace co-founder Rex Weyler describes to Gaia the motivations behind the original Save the Whale campaign, and some of his memories of intercepting a Russian whaling ship in 1975.Since 1982, cetacean science has come a long way, and scientists know far more about whale's behaviour, vulnerabilities and interaction with ocean climate and ecosystems than we did back then. Dr. Asha De Vos of the University of Western Australia describes the science, including some recent findings on the continued perils of anthropogenic noise to these giants of the deep.Presenter Gaia Vince Assistant Producer Joleen Goffin Produced by Alex Mansfield
Robotic Thumbs, Mending Bones with Magnets, and the State of Science this Summer
Gaia Vince takes you for a mosey around his year's Summer Science Exhibition, held by London's Royal Society. Along the way, PRS Sir Adrian Smith talks of reforming A-Levels and a sorry international science collaboration situation as many european research grants are terminated amidst a Brexit withdrawal agreement stand-offs.The Royal Society Summer Science Exhibition is on until Sunday 10th July, it is free to attend and there are many activities and events online too.Presented by Gaia Vince Produced by Alex Mansfield
10 Years of the Higgs Boson
In 1964 a theoretical physicist called Peter Higgs suggested a mechanism via which elementary particles of a new theoretical scheme could obtain mass. It had been a thorny mathematical stinker in the framework that today we now call the standard model of particle physics. Ten years ago this July, the particle this mechanism predicted, the Higgs Boson, was confirmed to exist in experiments conducted at the Large Hadron Collider at CERN.Prof Frank Close, whose new book - Elusive - is published this week, is a friend of Peter's. The book describes the background to Higg's idea, and how a generation of physicists worked to test it and identify it. He and Prof Malcolm Fairbairn of King's College London discuss the significance at the time, what we we've learned since, and what we might in the future.As covid cases are on the rise again in the UK, Prof Jonathan Ball gives Marnie his observations on the current variants. Prof Trevor Cox, acoustician at Salford University describes his part in a collaboration to design a new type of DIY facemask that still allows people to see your lips moving as you speak, whilst also muffling your words far less. It was developed with collaborators at University of Manchester, and also by Salford's Maker Space, and you can download plans and a video and have a go yourself at the link from our programme page.An article in Nature food recently suggested that our estimates of food miles, the carbon footprints we assign to the foods we eat, may have been underestimated and could be 3.5 times what was previously thought. But does that change the choices we make in what we buy?Presented by Marnie Chesterton Produced by Alex Mansfield
Engineering Around Mercury, Science Festivals, and The Rise of The Mammals
How hard is it to get to Mercury and why are we going? Also, do science festivals work? And why did mammals survive when dinosaurs died? Marnie Chesterton and guests dissect.As this programme went out, scientists and engineers eagerly wait for new images of the planet Mercury to arrive, snapped from a speeding probe passing just 200km from the surface, as it desperately tries to shed some velocity on its seven-year braking journey. ESA/JAXA's BepiColombo mission to Mercury is using gravitational swing-shots (just four more to go) to lose enough energy to eventually, in Dec 2025, enter orbit around the planet closest to our sun.Dr Suzie Imber of Leicester University has skin in the game, being co-investigator on one of the instruments that will eventually be able to teach us more than we've ever known about this bizarre world.Suzie is also last year's winner of the Royal Society's Rosalind Franklyn Award, and works hard doing science outreach talks and events to help inspire the next generation of scientists and engineers.Thurs 23rd June is International Women in Engineering Day, celebrating remarkable engineering as a career option. Report Emily Bird goes along to the Great Exhibition Road Festival to see how science festivals such as this one can help raise the profile of engineering and scientific endeavours in the society of tomorrow.One thing most kids like is Space. The other is dinosaurs. But what about long-dead Mammals? Prof Steve Brusatte of Edinburgh university is a palaeontologist and author whose last book on dinosaurs even led to him being consulted for the latest film in the Jurassic Park franchise. Why then does his new book focus on furrier beings in The Rise and Reign of The Mammals? He tells Marnie of the exciting millions of years of evolution that led to us, after the dinosaurs croaked their last,.Presented by Marnie Chesterton Reporting by Emily Bird Produced by Alex Mansfield
Inside Sentience
Marnie Chesterton and guests mull over the saga of an AI engineer who believes his chatbot is sentient. Also, climate scientists propose a major leap in earth system modelling, that might cost £250m a year but would bring our predictive power from 100 km to 1km. And the story of a Malaysian Breadfruit species that turns out to be two separate strains - something locals knew all along, but that science had missed.Philp Ball's latest book, The Book of Minds, explores the work still to be done on our conception of what thinking is, and what it might mean in non-human contexts. Beth Singler is a digital ethnographer - an anthropologist who studies societal reaction to technological advancement. They discuss the story this week that a google AI engineer has been suspended on paid leave from his work with an experimental algorithm called LaMDA. He rather startlingly announced his belief that it had attained sentience, publishing some excerpts from interactions he has experienced with it.Prof Dame Julia Slingo this week has published a proposal in Nature Climate Change, co-authored with several of the world's greatest climate scientists, for a multinational investment in the next generation of climate models. Currently, models of the global climate have a resolution of something like 100km, a scale which, they suggest, misses some very fundamental physics of the way rain, clouds and storms can form. Zooming into 1km resolution, and including the smaller physical systems will allow scientist to better predict extreme events, and crucially how water interacts in a real way with rising temperatures in different climes.And can zooming in on taxonomy reveal insights in conservation and biodiversity? Researchers in the US and Malaysia have described a species of breadfruit that has hitherto been considered one species by mainstream science. Locals have long described them as different species, and the genetics proves that view correct. Can more local, granular knowledge help us get a better handle on the conservation status of our planet's biodiversity? Emily Bird Reports.Presenter Marnie Chesterton Reporter Emily Bird Producer Alex Mansfield
Miscounting Carbon, EU Funding Stalemate, and How to Make a Royal Hologram
This week on inside science Marnie Chesterton is looking at how companies measure and account for their use of renewable energy, how politics is impacting science funding in the UK and the technology behind the Queen’s holographic stand in at jubilee celebrations. Dr Anders Bjorn from Concordia university in Montreal talks us through ‘Renewable Energy Certificates’ explaining how they can sometimes be disconnected from real-life reductions in emissions. As he explains in a paper in Nature Climate Change this week, this is a problem, with businesses buying renewable energy certificates that may, even with the best of intentions, mean that corporate estimates of how much they have transferred to renewable energy could be out by as much as two-thirds. For example, in Poland, where much of the grid is powered by fossil fuels, a company can buy RECs from energy producers in Norway, where so much of the grid is de-carbonised and users feel no need to purchase such a certificate. As negotiations on the New Greenhouse Gas Protocol get underway, and delegates in Bonn discuss COP 26 progress, yet more food for thought. In the UK, some long term collaborations and research structures are under threat as the ratification of UK membership of Horizon Europe continues to be delayed. This has led to some researchers running out of funds, some having to relinquish membership, and others moving to different institutions in Member Countries. Professor Nicky Clayton at the university of Cambridge has for many years run a “Corvid Palace” where she keeps very clever birds and examines their thinking. It is threatened with closure, and she is searching for funding to keep the research going, even setting up an open letter from academics around the world in support of this globally renowned facility.Carsten Welsh, a physicist at Liverpool University has also been impacted, facing a difficult decision about whether to give up leadership of his newly funded project or leave the country to pursue it. EU Horizon is one of the most ambitious and well-funded research and international collaboration schemes in science and with every EU nation signed up and countries like Canada and Japan keen to join too, it's no wonder the UK wants to take part. Martin Smith, head of policy lab at the Wellcome Trust explains what’s getting in our way and what might happen next for British scientists who rely on Horizon to fund their research. And finally, celebrations last weekend for the celebration of Her Majesty’s Platinum Jubilee were seemingly led by a holographic queen riding in the Golden State Coach at the head of the pageant in London. At least, that was how it was reported. But was it really? BBC Inside Science managed to track down the leader of the team that made it – whatever it was – happen, and in a generous world exclusive, Willie Williams, head of Treatment Studio, kindly spills the magic beans on quite how you make a Royal Hologram.

A Reign of Science
Society itself and the ways we live have been transformed in 70 years of science. Marnie Chesterton, Andrea Sella, and Gemma Milne take a tour of the archive to evaluate some of the biggest hits on Inside Science's jubilee list. What did we miss?Presented by Marnie Chesterton. Assistant Producer Emily Bird Produced by Alex Mansfield
Monkeypox, Pompeii aDNA, and Elephant Mourning Videos
Why are non-African monkeypox cases causing concern? Also, the first complete human genome from a Pompeiian cadaver, and how YouTube is aiding animal behaviourists.As cases of monkeypox appear strangely dispersed around Europe and elsewhere in the world outside of Africa, BBC health and science correspondent James Gallagher outlines to Vic the symptoms and some of the mysterious elements of this outbreak.In Pompeii, scientists have for the first time managed to sequence the whole genome of an individual killed by the eruption of Vesuvius in 79AD. Serena Viva of the University of Salento describes the site of two individual's tragic demise all that time ago, one female aged around 50 years, and a younger male, both leaning on a couch in a dining room. Geneticist Gabriele Scorrano describes how the ancient DNA (aDNA) was preserved and extracted, and how the male individual's genome was so well preserved it could be sequenced in full. As they suggest this week in Nature, there weren’t too many surprises in what they found, but the ability to do this sort of science opens up a new era of Pompeiian archaeological treasure.Faced with covid lockdowns and unable to observe in the wild, elephant conservationists Nachiketha Sharma and Sanjeeta Sharma Pocharel decided to see if videos uploaded to YouTube could enlighten science on rare behaviours of Asian elephants. African Elephants are known to have a strange fascination, even respect, for the death of other elephant individuals, especially those near to their families such as calves and parents. Asian elephants’ thanatological (death related) behaviour is less well observed however. But the researchers turned to videos of strange grieving-like behaviour to begin a catalogue of the different reactions such as carrying dead calves, standing guard, or vocalizing. They dedicate their work, published by the Royal Society, to the elephants involved.This sort of research, using video observations captured and shared by members of the public are proving rather useful to zoologists and animal behaviourists. Ximena Nelson of the University of Canterbury in New Zealand was one of the first scientists to suggest the usefulness of trawling the internet for odd video of animals and explains a bit more to Vic.Presented by Victoria Gill Produced by Alex Mansfield
Buried Mars Landers, Freezing Species, and Low-Tide Archaeology
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 lost animals as possible – after they’ve died. Biobanking – saving frozen tissue from dead animals for future cloning or other reproductive technologies could buy us time to prevent extinction - or even reverse it. Vic visits Nature's Safe, where technology used in pedigree breeding is being deployed to preserve the cells and tissue of endangered species when individuals die or are euthanised, for possible research in the future, or even cloning.Meanwhile, 2.5 miles off the coast of Jersey, archaeologists are holing up in a medieval fortress waiting for the few lowest tides of the year to give them access to the Violet Bank - an area of reef thought once to have been home to Neanderthal populations, but which now is for most of the year submerged by the sea. Marnie Chesterton has been talking to UCL’s Matt Pope between the ebbs and flows. Presented by Victoria GillReporters: Marnie Chesterton and Jonathan AmosProduced by Alex Mansfield
Running Rings Around Matter
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 biodiversity progresses, the number of species given a Latin name is also growing. So, where do scientists find their naming inspiration? In Royal Society Proceedings B this week, an analysis of nearly 3,000 parasitic worm species uncovered some intriguing patterns and worrying biases.

Precious Metals, Earlier Eggs, and Meaningful Meteorites
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 Perrins, of Oxford University, shares his thoughts on the changing woodland.And from new life to the very stuff of life. Could the building blocks of DNA have first been delivered to earth on a meteorite? In a paper in Nature Communications, scientists announce the discovery of the last two of the five key nucleobases locked in meteorites dating to the formation of the solar system. Samples of the Murchison Meteorite, a specific type of soft, loamy rock (CM2 carbonaceous chondrite) that fell to earth in 1969, have been re-examined, and the confirmation extends the ongoing debate around the nature and composition of terrestrial life's original crucible. Sara Russell, Professor of Planetary Sciences at London's Natural History Museum, helps Vic unravel the complicated and surprisingly controversial history of space rocks and primordial soup.Presented by Vic GillProducer: Alex Mansfield Reporter: Samara Linton
The Ebb and Flow of the Tidal Power Revolution
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 Briggs shares how lab-grown proteins could make our diets much kinder to the planet.And a recent study has found that a fifth of reptile species are at risk of extinction. Conservation scientist and study co-author Monika Bohm, Indianapolis Zoo in the US, tells us how, despite the gloomy findings, she remains hopeful. Presented by Victoria Gill Produced by Alex Mansfield and Samara Linton
Building Better Engagement
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, she looks at ways science education could be enhanced through building what her team call Epistemic Insight - transforming the nature of science education in society's younger members.Presented by Victoria GillProduced by Alex Mansfield and Samara Linton
A Trip-Switch for Depression?
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 Webb Space Telescope is poised to peer deep into the universe, we look at a recent image captured by its great predecessor, Hubble, which has thrown down a telescopic gauntlet. Astronomer Dr Emma Chapman, author of the book “First Light” guides us through these incredible pictures of the furthest, faintest, most ancient of stars yet seen.Presented by Victoria Gill Reporter: Samara Linton Producer: Alex Mansfield
Declining Data, Climate Deadlines and the Day the Dinosaurs Died
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 Tanis fossil site in North Dakota in the US have dug up a dinosaur's leg, complete with skin and scales. Is this 66-million-year-old fossil, alongside similar nearby victims, the key to unveiling those transformative minutes after the infamous Chicxulub asteroid struck the earth and ended the era of the dinosaurs? BBC science correspondent Jonathan Amos has seen the fossil and speaks with Paul Barrett of London's Natural History Museum about the significance of this un-reviewed new finds. And from earth to Mars. After a year of analysing audio recordings from NASA's Perseverance rover, scientists have found not one but two speeds of sound on Mars. Trevor Cox, Professor of Acoustic Engineering at the University of Salford, guides us through this sonic wonder, and how sound may become a key tool for exploring distant worlds.

How can the UK get to zero carbon?
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 homegrown lithium for batteries, and talk to Jonathan Atkinson from People Powered Retrofit about how to make our homes greener and warmer.
Racial inequality in UK science
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 not only helps wildlife but can reduce flooding and pollution. But what kind of hedge should you plant? Scientists at the University of Reading and the Royal Horticultural Society are beginning a two year experiment to see which combinations of hedges bring the most benefits. Dr Tijana Blanusa tells us why planting hedges and generally greening our gardens is so important in the current climate.Presented by Gaia Vince Producer Cathy Edwards Assistant Producer Emily Bird
Global food security during Ukraine conflict
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 also end, though the Office for National Statistics survey will continue. Given that case numbers are rising, is reduced monitoring wise? Professor Adam Kucharski from the London School of Hygiene and Tropical Medicine discusses how important surveillance has been in the pandemic. The last crewed mission to the Moon was half a century ago, and no one has made that one small step since. But a new NASA programme aims to change that, and tonight is the rollout of Artemis I, the first stage on a journey to return humans to the moon, including the first woman on the moon and the first person of colour on the moon. BBC science correspondent Jon Amos paints a picture of what we’ll see tonight.
High Seas treaty talks and discoveries from the deep
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 rest of the world may be impacted by the current conflict. And finally, the stunning discovery of a 330 million-year-old vampyropod fossil, the earliest known relative of modern-day octopuses and vampire squids, gives us an opportunity to imagine the world it inhabited, a third of a billion years ago.
Cyber frontlines in Ukraine
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 see a push towards renewables and energy efficiency, or further reliance on fossil fuels.

World’s largest Jurassic pterosaur found on Skye
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.

COVID-19: Beginnings... and endings?
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
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 to blue seas research, scientists have found a surprising seabed community that lives in the cold nutrient-sparse waters under the central arctic ocean: giant sponges. And it turns out these resourceful organisms have been feasting on the thousand-year-old remains of now-extinct worms. We hear from Teresa Maria Morganti from the Max Planck Institute for Marine Microbiology and Autun Perser from the Alfred Wegener Institute, Helmholtz Center for Polar and Marine Research.
The Continuing Story of the Nuclear Waste Bill
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 climate change, some as much as a month earlier, on average, since the pre-1986 average. Aaron Rice of Cornell University speaks fish. But not fluently. His field of marine bioacoustics is growing fast. The oceans are, it seems, babbling with fish and other animal chatter. But does everything down there make a noise? In a paper published recently his team have traced evolutionary patterns in the ray-finned fish (which means nearly all the things most people would think of as a fish) and found that the ability to produce fishy sounds, be it bone vibrations, swim bladder vibrations or various other techniques, has likely emerged 33 times in this clade alone. Such convergent evolutionary history clearly suggests a strong selective pressure to do so. Aaron describes how much work there is to be done listening to fish, and how it can be used to help find out how life works, and how it may help us preserve it.

Predicting Long Covid, and the Global Toll of Antimicrobial Resistance
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 promising bit of work, and also discusses some other potential clues to the Long Covid mystery.But Covid of course is not the the only major cause of death in the world today. A major paper in the Lancet recently is one of the first deep estimates of the global health burden of Antibiotic Microbial Resistance. And it suggests that 1.25 million people died in the world in 2019 because many bacteria are evolving a resistance to our favourite antibiotics. As Prof Chris Murray, Director of the Institute for Health Metrics and Evaluation at the University of Washington who led the massive collaboration explains. The surprisingly huge number points to a massive and growing problem that political and health leaders around the world must address.And finally, the genetics of fingerprints might be a bit better understood thanks to work published in Cell recently. Dr Denis Headon of the Roslyn Institute at the University of Edinburgh talks to Gaia about a huge survey he and colleagues have done looking at the hints certain genes can give as to the types of fingerprints you grow. The genes that seem to govern the general form of your prints are the ones that shape your limb development, rather than skin patterns as perhaps might be expected. And a pro-tip if you want to search the literature for more info on this: use the word "dermatoglyph" rather than the overused and progressively meaningless word "fingerprint".Presented by Gaia Vince Producer Alex Mansfield Assistant Producer Emily BirdMade in Association with The Open University.
The 'perfect' depth for a destructive eruption
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 Betts, Head of Climate Impacts at the UKs Met Office tells Gaia how current estimates of the recent eruption's emissions suggest it will not have such an affect, their being around ten times less than the 1991 event.Richard was one of the contributors to the UK Government’s Climate Risk Assessment 2022 which was published this week. He describes to Gaia some of the modelling that went into it, and the urgency of cutting CO2 and similar emissions it describes.Last year Prof Mark Miodownik, head of the Institute of Making at UCL made a series for Radio 4 called Dare to Repair, looking at the vanishing art and practice of repairing our old and malfunctioning consumer devices, rather than binning them and buying new ones as most of us do these days.At the end of 2021 Mark, together with representatives from manufacturers, consumers, and other groups, took part in a round-table meeting to discuss possible challenges and measures to increase the so-called Right to Repair, towards building a circular economy in the UK for recycling plastic and metals. In this week's show he launches a new citizen science project aimed at gathering granular data on UK citizens views and practices when it comes to "disposable" electronic devices. To take part in The Big Repair Project, to record successes and failures, even to share how impossible it can be sometimes to change a battery, follow the link on the BBC Inside Science homepage.Presenter Gaia Vince Producer Alex Mansfield Assistant Producer Emily BirdMade in Association with The Open University
The Rutland ‘Sea Dragon’, An Astronomer's Christmas and some Animal Magic
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 unexpected as the higher sea levels 200 million years ago would put the east midlands underwater. And whilst the palaeontologists have been struggling through the Jurassic mud, cognition researchers at the University of Cambridge have been wowing their birds with magic tricks. Professor Nicky Clayton FRS, Professor of Comparative Cognition, explains what we can learn about the way jays think by assessing their reaction to different sleight-of-hand tricks. Corvids, the family to which these feathered friends belong, have long interested researchers due to their impressive cognitive abilities and Nicky’s team has shown that their Jays are not fooled by all of the same mis-directions as we are, but are fooled by some. And it could be down to not being able to tell the difference between a finger and a feather.Presented by Marnie Chesterton Produced by Alex Mansfield Assistant Producer Emily BirdMade in association with The Open University
Deep ocean exploration
UCL oceanographer Helen Czerski explores life in the ocean depths with a panel of deep sea biologists. They take us to deep ocean coral gardens on sea mounts, to extraordinary hydrothermal vent ecosystems teeming with weird lifeforms fed by chemosynthetic microbes, to the remarkable biodiversity in the muds of the vast abyssal plains.Helen's guests are Adrian Glover of the Natural History Museum in London, Kerry Howell of Plymouth University and Alex Rogers, scientific director of REV Ocean. They discuss the dramatic revelations made by deep ocean explorers in just the last forty years, and the profound connections that the deep sea floor has with life at the Earth's surface. They also consider the threats to the ecosystems down there from seabed mining and climate change.Producer: Andrew Luck-BakerBBC Inside Science is made in association with the Open University.
A new space age?
Dr Kevin Fong convenes a panel of astronautical minds to discuss the next decade or two of space exploration.2021 was an eventful year in space. Captain James Kirk a.k.a William Shatner popped into space for real for a couple of minutes, transported by space company Blue Origin's tourist rocket New Shepard. Elon Musk's Space X ferried more astronauts and supplies between Earth and the International Space Station, using its revolutionary resuable launchers and Dragon spacecraft. On Mars, the latest NASA robot rover landed and released an autonomous helicopter - the first aircraft to fly on another planet. 2022 promises even more. Most significantly NASA plans to launch the first mission of its Artemis programme. This will be an uncrewed flight of its new deep space vehicle Orion to the Moon, propelled off the Earth by its new giant rocket, the Space Launch System. Artemis is the American space agency's project to return astronauts to the lunar surface and later establish moon bases. China has a similar ambition.Are we at the beginning of a new space age and if so, how have we got here? When will we see boots on the Moon again? Could we even see the first people on Mars by the end of this decade? Even in cautious NASA, some are optimistic about this.Kevin's three guests are:Dr Mike Barratt, one of NASA's most senior astronauts and a medical doctor, based at the Johnson Space Center in Houston, Texas Dr Anita Sengupta, Research Associate Professor in Astronautical Engineering at the University of Southern California Oliver Morton, Briefings editor at The Economist and the author of 'Mapping Mars' and 'The Moon'Producer: Andrew Luck-BakerBBC Inside Science is made in association with the Open University
The Origin of Celtic Culture in Britain?
Victoria Gill hears of ancient DNA evidence for an unrecognised mass migration from continental Europe 3,000 years ago that may even have brought the Celtic languages with it.In a paper in the journal Nature, an international team of researchers have gathered hundreds of middle-late Bronze Age DNA samples to identify a moment in pre-history when half the ancestry of people living in southern Britain became continental European. Sometime around 1000 BC, continental Europeans living in Kent spread rapidly into what is now England and Wales. As Prof Ian Armit tells Vic, the spread need not have been one event, and likely spanned around 200 years, but by the start of the Iron Age, Britons' DNA was 50% changed. The researchers suggest further that this may have been the time when Celtic languages spread from the continent into the islands too. Data are starting to be published that suggest the Omicron variant of SARS CoV-2 may be a little less awful than was first feared, though it clearly is still a lethal foe. Prof Penny Moore, one of the scientists in South Africa who helped alert the world to the new virus is very tentatively relieved that death and hospitalisation numbers there and in the UK are beginning to show clinically some of the resilience that earlier strains and vaccines may have bestowed on populations. Three "Glimpses of Spike", either through prior infection and survival or vaccination and boosting seem to be accompanied by improved survival rates.Gaia Vince has been to the Arctic Circle to talk climate change and reindeer. Sami language and culture in Lapland is under strain as climate change rapidly changes alters the predatory threats reindeer farmers face, increasing numbers of wolves and even sea-eagles that prey on young reindeer calves. And over at UCSC in California, recordings of elephant seal pups have been played to maternal harems to ascertain how well mothers recognize their own. Caroline Casey and colleagues report in Royal Society journal Biology Letters, how they can spot their own offspring from their call alone in as little as two days after birth. But if they can do that, why then do so many lactating females feed pups that aren’t their own? Elephant seal mothers fast throughout lactation and lose a huge percentage of their own body weight, quite what the evolutionary driver is for this behaviour remains uncertain, but it can’t now be a case of mistaken identity.

The James Webb Space Telescope
The launch of the James Webb Space Telescope is only days away. Scheduled for lift off on 24 December, the largest and most complex space observatory ever built will be sent to an orbit beyond the moon. James Webb is so huge that it has had to be folded up to fit in the rocket. There will be a tense two weeks over Christmas and the New Year as the space giant unfurls and unfolds. Its design and construction has taken about 30 years under the leadership of NASA’s Goddard Space Flight Center.With its huge 6.5 metre-wide primary mirror, the giant observatory promises to extend our view across the cosmos to the first stars to shine in the early universe. That’s a vista of Cosmic Dawn: the first small clusters of stars to form and ignite out of what had been a universe of just dark clouds of primordial gas. If the James Webb succeeds in capturing the birth of starlight, we will be looking at celestial objects more than 13.5 billion light years away. Closer to home, the telescope will also revolutionise our understanding of planets orbiting stars beyond the solar system.BBC science correspondent Jonathan Amos reports from the European Space Agency’s launch site in French Guyana from where James Webb will be sent into space. He talks to astronomers who will be using the telescope and NASA engineers who’ve built the telescope and tested it in the years leading to launch.Producer: Andrew Luck-BakerBBC Inside Science is made in association with the Open University.Image: James Webb Space Telescope.

Initial Omicron Lab Data, Creative Naps, and Fishy Sounds.
T-Cells in vaccinated people may be holding the fort, or at least fighting serious illness, against the latest SARS CoV2 variant. Also, how the briefest of sleeps aids creativity.Prof Penny Moore, of South Africa’s National Centre for Infectious Disease and Witwatersrand University in Johannesburg, joins us again this week to give us an update from the front line of scientists trying to get the data we need to try to predict the seriousness of the omicron variant. These early data, published as pre-prints and not yet peer-reviewed, seem to suggest that for those in the world lucky enough to have "seen a spike" three times (double vaccination plus booster, or double vaccination plus recovered from infection) the chances of serious illness remain similar to earlier variants.One chink of hope continues to be the fascinating response of the "killer" T-Cells. Prof Danny Altmann of Imperial College London attempts to give us a T-Cell 101 course. This other division of the body’s defences, besides the binding antibodies of which we hear so much, may be more resilient to the sorts of mutations the virus has shown so far, and also perhaps have a slower waning in their ability to recognize it at all.What did Salvador Dali and Thomas Edison have in common? A fondness for the occasional creative nap. And this week scientists suggest they weren't wrong.Delphine Oudiette, a sleep researcher at the L’Institut du Cerveau et de la Moelle épinière in Paris, has been experimenting with the idea that just a small nap, where you doze off for a few seconds but don't fall into deep sleep statistically helps you solve creative or mathematical problems. Her results are published in the journal Science Advances. Meanwhile, in shallow seas off Indonesia, attempts to regrow coral reefs previously pounded to rubble by fishing with explosives, really sound like they are recovering. How do scientists know? By swimming about with microphones of course. Dr Tim Lamont, a marine Biologist at the University of Exeter has been listening to thousands of recordings of fish and other marine animal noises and talks Vic through some of the odder ones that so far can't be recognized. He says the sheer number and frequency of the odd sounds point to an ecosystem beginning to thrive. The coral rebuilding strategy there won't work for all the world's dwindling corals, but this new way of monitoring success or failure makes for a great listen.Presenter: Victoria Gill Producer: Alex Mansfield Assistant Producer: Emily BirdMade in Association with The Open University
When Pandemics Collide
As virologists around the world race to investigate the latest SARS CoV2 variant of concern, the UN’s World AIDS Day this week reminds us of the other global pandemic raging for some 40 years. Much of the work achieved over the last two years on SARS CoV2 has been achieved because of the investment made into, and the understanding gained from, HIV research over the last two decades. But to what further extent do they overlap in the population? There is a theory that the omicron variant, displaying so very many mutations compared to previous variants, might well have been incubated in a person suffering from a compromised immune system, possibly due to HIV, in whom the covid virus was able to linger longer than in fitter individuals. Prof. Penny Moore, of South Africa’s National Centre for Infectious Disease and Witwatersrand University in Johannesburg, is one of many virologists who transferred from HIV to coronavirus research, and hers, like hundreds of labs around the world, is racing to clone the parts of the omicron virus to enable research into its transmissibility and severity as soon as possible. She describes to Vic what we yet know and what we don’t about it, and also how it is high time to bring the same sense of urgency back to HIV research.Nottingham University’s Prof. Jonathan Ball is another virologist who suddenly transferred experience over to coronaviruses early on. He outlines something of what is really happening when viruses mutate, and how the arms race between host and invader can play out. Our regular Inside Science listener will be interested to know that this week Merlin Sheldrake was awarded the Royal Society’s Science Book Prize, sponsored by Insight Investment, and the hefty cheque that accompanies it, for his book Entangled Life: How Fungi Make Our Worlds, Change Our Minds and Shape Our Futures. Merlin is one of several high profile advisors to something called the Society for the Protection of Underground Networks - SPUN. They have received funding recently to begin an international mission to map the world’s subterranean fungal mycelial networks, including the infamous Wood Wide Web. SPUN Co-Founder Prof. Toby Kiers of VU University in Amsterdam tells Vic about the need to preserve, map and cherish this unseen yet essential part of the global ecosystem.And could rising sea levels paradoxically be used to help fight climate change? Researchers up in St Andrews took Vic for a squelch about the salt marshes reclaimed recently by the sea in an estuary near Grangemouth, where flora and fauna are thriving just a few years since the seas were allowed back in. Finally, you may have thought that wasps eat meat whereas bees eat honey and nectar. But this week we learned that some bees eat meat, preserving it in honeycombs to feed young and augment their own nutrition. Intrepid field entomologist Laura Figueroa of Cornell University describes to Vic her work in the jungle with Vulture Bees, social bees that over evolutionary time seem to have rescinded their vegetarian instincts and now are happy to enjoy a bit of “chicken on the side”. Laura found that they can digest their flesh because of big adjustments to their gut microbes, including acid-loving bacteria also found in other carnivorous animals.

Malaria: what's in it for the mosquito?
Malaria, a disease that infects hundreds of millions of people and kills hundreds of thousands each year. It is caused after a plasmodium parasite is passed from a blood-feeding mosquito into a human host. Subject to much research over hundreds of years, of both host and parasite, one of the evolutionary mysteries has been why the plasmodium so prospers in the mosquito populations in infected areas. Why haven’t mosquitoes’ immune systems learned to fight back for example? In short, what’s in it for the mozzies? Ann Carr, working with Laurence Zwiebel at Vanderbuilt University, reports in the journal Nature Scientific Reports how they managed to discover a mutual symbiotic relationship between the plasmodium and the mosquito. Using advanced sequencing technology they discovered that the infected insects can live longer, and have enhanced sensing (olfaction) and egg positioning than their uninfected brethren. This, in turn, could help them finds meals better, bestowing higher numbers of infection opportunities for the parasite, and benefitting both.NASA this week successfully launched its DART mission, which will next year attempt to nudge an asteroid in its orbit by smashing a mass into it. Could this method allow future humans, endangered by an impending collision push an asteroid out of the way to save the planet? It is billed as human’s first ever “earth-defence mission”, but as relieved-sounding mission leads Nancy Chabot and Andy Rivkin of Johns Hopkins University told the BBC, it is perhaps finally time to stop talking about these sorts of things and have a go.Less relieved perhaps are astronomers around the world, as the James Webb Space Telescope team announce a further small delay to its launch to sometime after December 22nd. The BBC’s John Amos a few weeks ago stood in the presence of the telescope before it was coupled to the launch vehicle, and spoke with ESA’s Peter Jensen about its cost and complexity. BBC Inside Science is planning a special episode devoted to the instrument to accompany the launch of this successor to the Hubble Space Telescope. Watch, as they say, this space...And finally an insight perhaps into the origin of words and language. Apart from onomatopoeia, where a word can sound like the noise of a noise-making thing, can a word sound like other properties, such as for example its shape? In the late 1920s psychologists found that different people would match certain made-up words with the same abstract shapes. This “Bouba/ Kiki” effect has been studied since, where the word “Bouba” is associated with rounded blobby shapes, and “Kiki” with spikier, angular forms.But there wasn’t so much evidence whether or not the effect worked across different languages or different written alphabets, until now.Aleksandra Ćwiek of Leibniz-Zentrum Allgemeine Sprachwissenschaft in Berlin tells Gaia of her international study (published in Royal Society Phil. Trans. B) looking at the effect in 25 different languages and cultures. The effect is robust across the different writing systems and locations, so the link is not simply about the shape of a letter b or letter k when written in a latinate alphabet, but could allude to something much deeper.Presented by Gaia Vince Produced by Alex Mansfield Assistant Producer, Emily BirdMade in Association with The Open University.
Yet More Space Junk; COP-up or COP-out; The End of Bias.
Earlier in the week the current ISS crew had to prepare to evacuate after Russia tested an anti-satellite weapon, spreading thousands of high velocity shards of ex-satellite into a reasonably low-earth orbit and potentially endangering many other earth observation and communication satellites of all nations. How can we clear this and all the other debris? BBC Space Correspondent Jonathan Amos tells Gaia Vince about the Russian test and of efforts to de-orbit some other deceased orbital vehicles.Simon Evans, deputy editor of the website Carbon Brief, was one of many attending the COP26 summit which ended at the weekend. How do all the declarations, promises and the "Glasgow Pact" itself add up in the great carbon ledger we all need to worry about? And the last of BBC Inside Science's Royal Society book prize nominees, Jessica Nordell talks to Gaia about writing her book "The End of Bias: A Beginning: The Science and Practice of Overcoming Unconscious Bias".

Propane: Keeping Your Cool as the World Warms Around You
How propane might prevent air conditioning and refrigeration becoming an even bigger burden as our planet warms. Also, covid antiviral pills, and how we forgot to breathe properly.The Montreal Protocol is famous for reducing CFC emissions to help protect the Ozone Layer. We only started using things like CFCs as refrigerants in our fridges and air-conditioning because they weren't as flammable as many alternatives. They were mainly replaced by HFCs, though these are also on the way out. The reason? Their huge greenhouse warming potential (or GWP). Propane has long been thought to be an alternative because of its comparatively tiny GPW, but the safety standards haven't been in place in much of the world for many of the types of application that would make the big difference. Sophie Geoghegan, Climate Campaigner at the Environmental Investigation Agency, and Asbjørn Vonsild who has been working on some of the new standards, due to become normal in Europe next year tell Gaia what greenhouse savings there are to be made, both in terms of efficiency and the contents of the systems themselves. If public opinion and consumer choice can drive the transition as our cities heat up.This week two new Anti-viral pills that are designed to fight SARS CoV2 infections have made headlines in the UK. Professor Penny Ward is Chair of the Faculty of Pharmaceutical Medicine’s Policy Expert Group, and explains how they work, how they were developed, and when they will be properly available. And in the penultimate of our 2021 Royal Society Insight Investment Science Book Prize shortlisted authors, science journalist James Nestor describes his book, Breath: The new science of a lost art. The book documents James’s journey around the world investigating traditional eastern practices, the latest pulmonology research, and learning from the palaeontology of ancient skulls, and he attempts to cure himself with better breathing habits.Presented by Gaia Vince Produced by Alex MansfieldMade in association with The Open University
How Whales Farmed For Food, COP progress, and The Last Stargazers
Gaia Vince hears how blue whales' huge appetites and energetic eating behaviours helped generate more food for themselves. Also, an update from COP26, and Emily Levesque on The Last Stargazers.New research published this week in the journal Nature reveals new insights into blue whales eating habits. Matthew Savoca and colleagues suggest these biggest of marine animals actually eat up to three times the mass of krill previously estimated. And they do this by finding the blooms of krill and using a spectacular lunging approach to open their massive mouths and filter the gulp of seawater for tonnes of food. But how come, since the near destruction of their population by commercial whaling in the twentieth century, are current krill populations lower than when the voracious whales themselves were far more numerous? Shouldn't there be more krill now than then?The answer, as Victor Smetacek, of the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research in Bremerhaven, describes to Gaia is that whales themselves help to keep iron in the upper waters of the southern oceans, re-fertilizing it for the lower ecosystem member like phytoplankton, and their powerful diving lunges and defecation effectively plough the waters, akin to herds of bison treading manure into prehistoric grass plains.Former GSO David King, of the Centre For Climate Repair at Cambridge University, is beginning experiments next year that seek to mimic this whale-defecation effect to bring about eventual repopulation of whales and fish to allow the oceans to restart this historical cycle.From Glasgow, above the hubbub of delegates and dignitaries CarbonBrief's deputy editor Simon Evans talks to Gaia about his perceptions of progress so far at the COP26 climate summit. Amongst the flurry of declarations so far this week, what are the details and how do they add up towards our eventual recovery back down to the 1.5C rise everybody is talking about?And in the latest of Inside Science's interviews with shortlisted finalists of this year's Royal Society Insight Investment Science Book Prize, Prof Emily Levesque, an astronomer at Washington State University tells Marnie Chesterton of her adventures and astronomical anecdotes at some of the world's most famous observatories. Researching her book, "The Last Stargazers: The Enduring Story of Astronomy’s Vanishing Explorers", she interviewed hundreds of practicing and practical astronomers, many of whose jobs, she suggests, will soon be transformed as the act of observation becomes more remote, automated, and data-heavy.

Atmospheric Pollutants and Where to Find Them
This week London's Ultra Low Emission Zone was extended to 18 times its previous size. In an effort to cut levels of various nitrogen oxides and other gases dangerous to humans from urban air, cities encouraging lower emission vehicles is a trend soon stretching across the UK and other European countries. But some are sceptical as to their efficacy. Dr Gary Fuller of Imperial College London is author of The Invisible Killer, and has been studying the air in London and elsewhere since these zones began.As COP26 begins in Glasgow, a wealth of climate science is being published and publicised. Victoria Gill describes a couple of stories this week that point out quite how complex the science is, let alone the diplomacy and economics. Whilst the world's forests taken as a whole undoubtedly still capture more CO2 than they release, research this week shows that ten of Unesco's World Heritage Forests - making up for an area twice the size of Germany - have in the last ten years actually moved from being a carbon sink to a carbon source. There are several reasons, land use pressure being one of them, but also extreme climate events like wildfires (and even a hurricane in one instance) have tipped the balance, and show what how sharp the knife edge is for natural resilience. Meanwhile, the Financial Times reports that scientists have found an unexpected outflow of methane into the atmosphere from a site very close to the COP26 conference centre in Glasgow, highlighting just how great a challenge net zero will be.Alongside some of humans' most earth-changing achievements, the domestication of the horse stands as something outstanding in human history. Without it, war, traded and culture would be unrecognizable. But quite when and where the modern horse originated has been something of a mystery. In Nature this week, researchers have published an extensive study into ancient DNA that seems to pinpoint finally a moment and a place where this happened, 4,200 years ago. Geoff Marsh takes Marnie for a canter through the mystery. Presenter: Marnie Chesterton Producer: Alex Mansfield Made in association with The Open University
The Possible Impact of false-negative PCR Tests
As many as 43,000 PCR tests for people living in and around the South West of England could have been wrongly returned as negative recently, thanks to a seemingly unknown error, or errors, at a laboratory near Wolverhampton. For an extraordinarily long time the mistakes went undetected, and every day many hundreds of people who really had Covid, were told they hadn't.To discuss the numbers and difficulty in calculating the full tragic consequences of the events, Marnie Chesterton speaks to Dr Deepti Gordasani of Queen Mary, University of London, and Dr Kit Yates, of Bath University.How many people may have died as a result of this? BBC Inside Science's back-of-the-envelope suggests 500-1000 preventable deaths, and counting..As accusations of fossil fuel lobbying begin to encircle the pre-negotiations of the COP26 negotiations, we heard last week of the sad death of Dutch climate scientist Geert Jan van Oldenborgh. Listeners to BBC Science programmes will recognise his work from earlier this year, as flash floods and heatwaves ravished Europe and North America, when he and his colleagues at the World Weather Attribution Initiative were able to say unambiguously that these events could only have happened because of anthropogenic climate change. Roland Pease looks at Geert Jan's work and legacy.And the latest of the Royal Society Book Prize finalists to speak to BBC Inside Science is Stuart Ritchie, a psychologist at Kings College London. His book explores the murkier corners of science as a process. Certainly the so-called replication crisis has dogged psychological sciences for several years, but in "Science Fictions: How Fraud, Bias, Negligence, and Hype Undermine the Search for Truth" Stuart outlines quite how deep some of the flaws in the modern experimental reporting and publishing model go, and in almost all fields. However, as he explains to Marnie, there may be ways of rescuing the great achievement of the scientific method by tweaking some of our peer-review norms.Presented by Marnie Chesterton Produced by Alex Mansfield Made in association with The Open University
Early Alzheimer's Alert
Marnie Chesterton hears of a simple test for the earliest signs of Alzheimer's disease. She finds out about UK scientists using robots to map radiation at Chernobyl, and talks to Merlin Sheldrake about fungi.Roland Pease travels to Bath University to meet scientists who may have developed a way to diagnose Alzheimer's in the earliest stages of the disease. Dr George Stothart, has led the team in the development of this simple 2 minute test.Prof Thomas Scott of Bristol University and team develop robotic techniques to scan areas of high radiation that would otherwise be unsafe for humans to enter. Their rolling, quadruped or even flying robots have recently been deployed in and around the reactor building at the Chernobyl disaster site. Authorities there have recently been licensed to begin disassembling remains inside the vast concrete shield, but as they do so, areas of intense radiation are likely to shift from day to day. Being able to map these changes in 3D at the end of each working shift should enable workers to avoid the areas of biggest danger.Dr Merlin Sheldrake is one of the nominees for this years Royal Society Insight Investment Book Prize. "Entangled Life - How Fungi Make Our Worlds, Change Our Minds, & Shape Our Futures" is a rich tale of interconnectedness and subtle intrusion and extrusion between different living things, and particularly fungi's huge influence on human existence, from beer, bread and psychedelia to the whole history of life on earth.Presented by Marnie Chesterton Produced by Alex MansfieldMade in Association with The Open University
Surprising choice for Nobel prizes in a pandemic?
This week saw the announcement of the Nobel prizes for physiology or medicine, chemistry and physics. None of them reward research connected with Covid. Roland Pease, science journalist and Nobel watcher, and Gaia Vince discuss the decisions, which some have said are controversial in this pandemic year. The BepiColombo space craft, a joint European and Japanese mission, has just completed its first fly-by of Mercury, after a three year journey. Professor Dave Rothery, a planetary geologist at the Open University, who’s been involved since the early days of the mission in the 1990s, talks about what Mercury's cameras have seen and what the mission aims to find out when it finally gets into orbit around the planet in 2026.Plants remove carbon from the air during photosynthesis, and forests will be a key part of meeting our climate goals. But there’s a lot of uncertainty about how forests will react as temperatures and CO2 rise. Now researchers at University of Birmingham have bathed ancient oak trees in the sort of carbon dioxide concentrations we expect in 2050, and measured the impact. Anna Gardner led the research from a forest in Staffordshire. The shortlist for the Royal Society Insight Investment Science Book Prize for 2021 was announced last week. Inside Science will be featuring the six authors. The first is The Sleeping Beauties: And Other Stories of Mystery Illness by Suzanne O’Sullivan. She's a consultant neurologist at the National Hospital for Neurology and Neurosurgery in London, who’s been described as “a detective of the mind”. Suzanne O’Sullivan specialises in epilepsy but this leads her to see a number of patients with symptoms such as unexplained paralysis or blindness. For The Sleeping Beauties, she travelled around the world investigating what is often referred to as psychosomatic illness. Sometimes whole groups of people have been affected in mysterious ways. Claudia Hammond spoke to her about the strange case of refugee children in Sweden who fell asleep for years at a time.
Covid vaccine boosters; why we don't have a tail; cassowary domestication; Royal Society Science book prize shortlist
Booster vaccines are now being offered to people in England most at risk of Covid, who had their second jab at least 6 months ago. Most people are getting an mRNA vaccine as a booster, mainly the Pfizer one. Dr Andrew Ustianowski, national clinical lead for the UK COVID Vaccine Research Programme, and infectious diseases consultant in Manchester, explains why people are not being offered new vaccines, specifically tweaked to prevent the current highly transmissible delta variant. And he talks about a trial with a new vaccine that works against more than just the spike protein. Why don’t we have a tail? We share that absence with our primate cousins, the great apes. What made the difference genetically speaking has eluded scientists, until now. Professor Jef Boeke of NYU Langone Health tells Gaia Vince why it was a change in just one gene that caused us to lose our tail.New research just published in PNAS pushes back the origins of farming by thousands of years. Professor Kristina Douglass of Penn State University and team studied 18 000 year old eggshells of cassowaries, found in human shelters in New Guinea. She explains how the finds suggest that these Pleistocene people had domesticated these large flight less birds. And six authors this week learned that their books have made the shortlist of the Royal Society Insight Investment Science Book Prize for 2021. Chair of the judges, Luke O’Neill, Professor of Biochemistry at Trinity College Dublin, tells Gaia how the panel made their choices from the 350 books entered.
La Palma volcano; wind energy in the UK; origins of SARS-Cov2; Formula 1 safety
Thousands of people have been forced to flee the path of the lava that has been spewing from the Cumbre Vieja volcano on La Palma since Sunday 18th September. Dr Rebecca Williams of Hull University is an expert on the geology of the Canary Islands and tells Gaia Vince that eruptions are regular events on the islands. There's been much discussion about where we are going to get our energy from in the UK. Gas prices are soaring, a fire has knocked out a key power cable, and the weather has affected the amount of power that can be generated from our wind turbines. And to meet our climate targets we're going to become ever more dependent on renewable, and variable, sources. Tom Butcher from the Met Office talks about wind forecasting. He says that the winds have been between 10% and 20% lower in intensity this summer. Professor Deborah Greaves, of Plymouth University and Head of the Supergen Offshore Renewable Energy Hub, explains how the UK is planning to increase the number of wind turbines, moving into deeper waters. A team from the Institut Pasteur in Paris, investigating bats in caves in Northern Laos, has found bats that are infected with a coronavirus that’s genetically almost identical to the one now causing Covid in humans. Lead researcher Dr Marc Eloit discusses what they have discovered and how coronaviruses could move from bats to humans. Lewis Hamilton and Max Verstappen had what looked like a very serious crash at their recent Formula 1 race in Italy. Max Verstappen’s car landed on top of Lewis Hamilton’s, but amazingly Hamilton got out unscathed. The safety features on these cars which can travel at more than 200 mph, are very sophisticated. Nick Wirth, a Fellow of the Royal Academy of Engineering who has many years experience of engineering in the F1 world, describes the Halo which saved Lewis Hamilton's life.
Perseverance drills on Mars; space tourism; Australian fire debris and algal blooms; DNA vaccines against Covid
NASA's Perseverance rover has been trundling around the Jezero crater since it landed successfully in February 2021. A few weeks ago it made its first attempt at collecting a sample of rock. Unfortunately the rock turned out to be so crumbly it disintegrated away. But Perseverance lives up to its name and has been drilling elsewhere and has now collected two samples. The rover has stored them in special canisters for later collection. Katie Stack-Morgan, Deputy Project Scientist of the Mars 2020 mission at NASA, tells Gaia Vince what they've found out so far.The Inspiration 4 mission has just blasted off from the Kennedy Space Center with 4 civilian astronauts on board. Unlike previous billionaire space flights, which have shot up far enough to officially cross into space before immediately returning, these four are going further out than the International Space Station, where they will orbit the earth for three days. BBC Science Correspondent Jonathan Amos talks about the recent boom in space tourism, and about the Chinese rover on Mars. The terrible Australian wildfires of the summer of 2019/20 had a devastating impact, burning across more than 18 million hectares and causing loss of life and livelihoods.. Now, it turns out the impacts stretched far beyond Australia. Climate scientists have been looking at satellite images of the vast Southern Ocean, which plays a major role in controlling the global climate, and found massive algal blooms, fertilised by debris blown thousands of kilometres from the fires. Gaia discusses the observations with Nicolas Cassar of Duke University, one of the authors on a recent Nature paper, and what they tell us about geoengineering to cool down the earth. This month India licensed the world’s first DNA vaccine against Covid. Jonathan Ball, Professor of Virology at the University of Nottingham, is involved with a DNA vaccine that is just starting in clinical trials. He explains the pros and cons of this kind of vaccine. It could be of benefit to those who are needle phobic.
Climate change and oil and gas exploration; cutting methane emissions; African wild dog populations; freezing eggs and sperm
We’re just weeks away from the big international climate talks in Glasgow, where governments will be trying to figure out a workable plan for how to keep global temperature rise below 1.5 degrees. Gaia Vince explores a couple of strategies to tackle climate change.By far the biggest source of the rise comes from the release of greenhouse gases when we burn fossil fuels, like coal, oil and gas. So it’s no surprise that we need to cut back on this habit - but much of the discussions are over how much of our reserves countries can continue to burn. Earlier this year, a landmark report from the International Energy Agency said there must be an immediate end to new fossil fuel exploration, and that current production must drop by 75% by 2050 if we are to stay within emissions targets. Daniel Welsby from UCL talks to Gaia about his just published massive analysis of fuel reserves and extraction. His study doesn’t go as far as the IEA’s, but still says that 60% of the remaining oil and gas, and 90% of coal reserves must stay underground if we are to keep below that 1.5C temperature rise. Natural gas, or methane, has a much stronger effect on temperature than carbon dioxide, but because it doesn’t last very long in the atmosphere before converting into carbon dioxide, it’s been a bit overlooked by governments. Two recent reports, from the IPCC and the UN, have pointed out that cutting methane emissions would be a quick win in reducing global heating. Most of our methane emissions are because of leaks from the oil and gas industry, or from landfill sites and agriculture. Gaia discusses tackling methane with Drew Shindell, of Duke University in North Carolina, the author of the Global Methane Assessment from the UN Environment Programme. Climate change is already having an impact on life everywhere. We’ve all seen the powerful pictures of polar bears on melting ice, but global warming is also causing problems for species in the tropics. Dani Rabaiotti of the Zoological Society of London explains how climate change is having an impact on African wild dogs, a species which is already endangered. This week the Human Fertilisation and Embryo Authority A recommended that the time limit for using frozen eggs, sperm and embryos, should be extended from 10 years to 55 years. Shahnaz Akbar, a fertility expert at Luton and Dunstable Hospital, explains what has changed in the science of preserving eggs from when the law was originally passed.
Rugby and the brain
Victoria Gill talks to Professor Damian Bailey who's leading research at the University of South Wales into the potential risks to brain health in contact sports players, from impacts to the head and body sustained during play. His latest study found that over the course of a 31 game season, the brains of members of a professional rugby union team underwent measurable changes, particularly the forward players who sustained most tackles, knocks and falls. The findings may help to identify why professional players of some contact sports are at an increased risk of dementia later in life.

Professor Titirici was awarded this year's Kavli Medal by the Royal Society for her research on new sustainable energy materials.The bones of people who died in 79 AD during the eruption of Vesuvius have revealed in extraordinary detail what the citizens of Herculaneum ate, and how the diets of men differed from those of women in the town. With bioarchaeologist Oliver Craig of the University of York.How the babbling of baby bats is comparable to babbling in human babies. Both are about learning the skills of communication, according to zoologist Ahana Fernandez of the Museum of Natural History in Berlin.
Window to solve pandemic origins closing
Virologist Marion Koopmans is one of the independent researchers appointed by the World Health Organisation to investigate the origins of the coronavirus pandemic. The team visited China in January this year as a first step to answer how, when and where SARS-Cov-2 first infected humans. Professor Koopmans tells Victoria Gill that time is beginning to run out to launch the next phase of studies, to trace the first people in China to be exposed and identify the animals from which the virus jumped the species barrier. Also in the programme:Is the practise of feeding the birds in our gardens creating losers as well as winners, and causing the numbers of some woodland birds to decline? Conservation biologist Alexander Lees visits Victoria in her garden to discuss the question, and reveal the truly dark side of the Great Tit.A new study of the impact of street lighting on nocturnal insects shows that the local impacts on moths can be dramatic. According to entomologist Douglas Boyes, street lights deter female moths from laying their eggs and make them more vulnerable to predation by bats. He's found that artificially illuminated areas are home to half the number of moth caterpillars compared to dark areas.
