Micro Nuclear Reactors

Guest presented by Liz Bonnin.

As the UK strives to achieve net zero by 2050, nuclear energy is looking more and more likely as a key player in reaching this goal. But it’s not just massive power plants like Hinkley point C - there’s are newer smaller reactors on the scene: small and micro modular reactors. 100 to 1000 times smaller than a conventional reactor, faster to build, and put together entirely in a factory before being shipped out, theoretically, anywhere: are micro modular reactors the future of nuclear energy or too good to be true? Dean of Engineering at the University of Liverpool, Eann Patterson, has just published a paper proposing a fleet of micro modular reactors to bear the burden of our energy load and he joins us to discuss the reality.

What came first, the chicken or the egg? Science writer, broadcaster and now egg expert Jules Howard joins us to answer this age old question. His book Infinite Life tells the story of how the egg propelled evolution – whether it’s bird, insect, or mammal.

This month, scientist Alexandra Freeman’s appointment to the House of Lords was announced. With a background in risk and evidence communication, Alexandra tells us why she applied, what she hopes to achieve, and how the public can get involved.

Declining Data, Climate Deadlines and the Day the Dinosaurs Died

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?

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

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

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

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

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

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.
