  • China's green growth plan

    11/03/2021 Duración: 27min

    On Friday 5th March China published a draft for its 14th five-year plan in Beijing. The document acts as a national economic blueprint and was expected to provide an outline as to how the world’s biggest emitter of greenhouse gas emissions planned on tackling its target of reaching net zero emissions by 2060, put forward by President Xi Jinping last September. It appears that greenhouse emissions could continue to increase by 1% or more each year up until 2021. Sam Geal, acting CEO at China dialogue, explains how influential Chinese efforts are when combatting climate change. Since the late 1980s conservationists have used captive breeding to prevent the extinction of North America’s only native ferret species, the black footed ferret (Mustela nigripes). Now, an individual called WIlla, who died without leaving any offspring over 30 years ago has been cloned. Her genes represent 300% of the current genetic diversity of the species, and could help boost the chances of these animals. Dr Bridget Baumgartner wor

  • Blue carbon; inside Little Foot's skull; reading locked letters

    04/03/2021 Duración: 30min

    With global warming continuing to increase at an alarming rate, we need all the help we can get to lock up the carbon that we’ve released into the atmosphere. Fortunately, plants have evolved to do just this, but there’s a whole class of plants that often get forgotten: the mangroves and seagrasses that grow between land and sea, which are among the planet’s most effective carbon sinks. Gaia Vince talks to Fanny Douvere, head of the marine programme at UNESCO, about its new report that shows the importance of blue carbon locked up in its marine World Heritage Sites. And Professor Hilary Kennedy, of Bangor University, explains why seagrasses are so effective at locking up carbon. Roland Pease reports on the secret journey made by one of the most valuable of human fossils, Little Foot, from Johannesburg to Oxfordshire, where it was scanned at the Diamond Light Source facility – one of the most powerful X-ray machines in the world. He talks to some of the main players about the hush hush voyage, and what they’re

  • Good COP Bad COP, Shotgun Lead Persistence, and Featherdown Adaptation

    25/02/2021 Duración: 30min

    On Thursday, The UN Environmental Programme published a report called Making Peace With Nature. It attempts to synthesise vast amounts of scientific knowledge and communicate “how climate change, biodiversity loss and pollution can be tackled jointly within the framework of the Sustainable Development Goals”. But it also offers clear and digestible messages that governments, institutions, businesses and individuals can act upon. Concluding BBC Inside Science’s month-long look at some of the challenges ahead of COP26 in Glasgow later this year, and its sister biodiversity meeting in China, Vic speaks with the report’s co-lead Prof Sir Robert Watson FRS and the Tyndall Centre’s Prof Rachel Warren, also a contributing author. Can all the ills of the natural world really be tackled at once?Game-shooting, for sport and food, has traditionally used the toxic metal lead for ammunition. In other parts of the world its use has been banned for the dangers to the human food chain and to the pollution in natural environ

  • Nasa's Perseverance - will it pay off? And spotting likely hosts for future pandemics.

    18/02/2021 Duración: 49min

    On Thursday 18th Feb 2020 Nasa’s Perseverance Rover is due to touch down – gently and accurately – in the Jezero crater on Mars. Using similar nail-biting Sky Crane technology as its predecessor Curiosity, if successful it will amongst many other things attempt to fly the first helicopter in the thin Martian atmosphere, and leave small parcels of interesting samples for future missions to collect and return to earth. Unlike previous Martian landings of course, there are no mass-landing parties to be held because of Covid. So Vic Gill invites you to join her and current Curiosity and future Rosalind Franklin (ESA’s 2023 Rover) team scientists in nervously awaiting the signal of success.Dr Susanne Schwenzer was so tense during Curiosity’s final approach in 2012 that she managed to draw blood from her own hand from clutching her mobile phone too hard. BBC Inside Science expects nothing less this time round. Dr Peter Fawdon has been part of the team seand examining the landing site for ESA’s Martian lander and Ro

  • Meeting Mars, Melting Ice, Ozone on the Mend Again, and A Sea Cacophany

    11/02/2021 Duración: 41min

    Victoria Gill and guests discuss the signs and symptoms of melting ice and anthropogenic climate warming, illicit CFC production and the racket we make in the seas. As two robotic missions from UAE and China arrive at Mars , and a third from NASA arrives next week, UK astronaut Tim Peake talks of the international collaboration in Mars research that is to come. And continuing BBC Inside Science's look at some of the issues facing COP26 delegates to Glasgow this autumn, Victoria is joined by cryosphere scientist Dr Anna Hogg,Anna studies – sometimes from space - how polar and Greenland ice sheets are melting and shifting as our climate warms. But those giant volumes of ice and concomitant rising sea levels might not be the only threat to people’s lives. It may be that the recent deadly flash flood in India was a result of a swiftly melting Himalayan glacier.The Montreal treaty - prohibiting the production of CFCs to allow the man-made polar hole in the Ozone layer identified back in the 1980s to repair - has l

  • Putting a number on biodiversity

    04/02/2021 Duración: 41min

    Ahead of the COP summit in Glasgow at the end of the year, this week an important study was published that attempts to enumerate the value of biodiversity in the economics of humankind. Prof Sir Partha Dasgupta's review makes it clear how essential and yet vulnerable it is.Trees play a large part in the biosystems of the planet, and replanting them is often touted as a solution to many of the carbon challeneges of the next century. But a paper and forthcoming conference hosted by Kew points out just how carefully reforestation - let alone afforestation - must be conducted.Kew tree expert Kate Hardwick tells Victoria about their 10 golden rules of planting trees.In a forest in Borneo, trees have been planted that will extract the high levels of Nickel from the local soil. It is hoped that the biomass from the trees can then be used to harvest the nickel. It is an attempt to commercialize successfully the dreams of "phytomining" - finding specific crops or traits in plants that can act to "hyperaccumulate" mine

  • Next Gen Covid Vaccines; Man's Oldest Bestest Friend; Bilingual Brain Development

    28/01/2021 Duración: 35min

    A year after the first SARS-Cov2 sequences were received in the vaccine labs, Dr Alex Lathbridge and guests look into ongoing development and what next year's booster shots might be like. Prof Robin Shattock's team at Imperial College are still working on their vaccine technology - called 'Self Amplifying RNA' or saRNA. A little bit behind their well financed corporate colleagues, this week they announced that instead of pressing ahead with a phase III trial, they will instead look to developing possible boosters and alternative targets just in case more and more serious mutations happen. But as Prof Anna Blakney explains from her lab at University of British Columbia, the possibilities of saRNA don't stop with coronaviruses.Researchers in the journal PNAS report this week a new theory as to when and where dogs were first domesticated by humans, and suggest that they accompanied the first humans across the Bering straight into America. Inside Science's Geoff Marsh has a sniff around.And Dr Dean D'Souza from A

  • Vaccine Hesitancy and Ethnicity; The Joy of catnip; Lake Heatwaves

    21/01/2021 Duración: 30min

    Reports this week talk of some BAME ethnic minorities being significantly less likely to take a covid vaccine if offered. Vittal Katikireddi and Tolullah Oni both sit on the SAGE ethnicity subgroup, and they discuss with Alex Lathbridge where the figures come from and quite what they might mean. Some of these same groups have suffered some of the worst outcomes from infection. Addressing any underlying problems that bely the figures will take a nuanced approach.Researchers in Japan and Liverpool have been investigating cat's prediliction for the herbs Catnip and Silver Vine. It turns out that there may well be a deep evolutionary reason they have evolved to love rubbing it in their fur so much: a key ingredient is a good mosquito repellent. As Professors Masao Miyazaki and Jane Hurst describe. It could help keep the mozzies away but you might end up being tailed by cats.And researcher Iestyn Woolway of the European Space Agency Climate Group, at Didcot UK, describes his work modelling the world's lakes' reac

  • UK Science post Brexit; GMOs vs Gene Editing regulation; Identical Twins That Aren't Indentical

    14/01/2021 Duración: 32min

    In the new EU-UK deal, the UK is to be an associate member of the latest EU research funding round, known as Horizon Europe. Costing around £2bn to take part, what can UK scientists now do and what has changed? UKRI CEO Otteline Leyser and the Wellcome Trust EU specialist Beth Thompson discuss ways in which UK researchers are breathing a sigh of relief.Of all the ways the UK can now diverge from the EU, DEFRA is currently holding an open consultation on whether to tweak the current GMO regulations so as not to include CRISPR-style Genetic Editing. The EU is coincidentally looking at the same issue. John Innes Centre's Janneke Balk works on making strains of wheat that have a higher level of iron for nutritional fortification. Interim head of the Roslin Institute in Scotland Bruce Whitelaw thinks developing disease resistance in farm animals is a potentially profitable area. Both agree the GMO regulations should be more tightly specified to bring clarity and opportunity for innovation. In Iceland, Kari Stefans

  • Vaccine Dosing and Biodiversity Soundscape Monitoring

    07/01/2021 Duración: 38min

    After the decision by the UK government last week to change the spacing between dosings of vaccine from the recommended 3 weeks to 12 weeks, immunologists around the world have been discussing with some urgency the wisdom of such a move. The FDA and the WHO are deeply sceptical, and the manufacturers have distanced themselves to some extent, by cautioning not to deviate from the regime tested in last year's phase III trials. The thinking behind the move is to get more people injected with a single dose in a shorter time, and that the longer wait for the second shot is worth the risk, if it means more people receive some level of protection in the short term.Clinical Epidemiologist Dr Deepthi Gurdasani and Immunoligist Prof Danny Altmann of Imperial College describe to Marnie how evidence, experience and hunch are combining in the face of the covid crisis, and quite what we know, what we don't and what we could, about this nationwide experiment. Increasingly, ecologists wanting to monitor remote areas are rely

  • Brian Cox and Alice Roberts on a decade of extraordinary science

    31/12/2020 Duración: 38min

    As a new decade ticks over, Dr Adam Rutherford, Professor Alice Roberts and Professor Brian Cox look back on a decade of science that has transformed perceptions of our medicine, our history and our universe.From advances in genetics that have brought personalized medicine to reality, and revealed the ghosts of ancestral human species never before identified, to quantum computing lessons that hint at the nature of existence and causation throughout the universe, it has been an interesting time. New observational technologies have revealed fresh windows in time and space. And all of it has been reported by BBC Inside Science. But what of the next decade? Programme may contain traces of informed speculation, but (almost) no references to Covid.Presented by Adam Rutherford Produced by Melanie BrownMade in association with The Open University.

  • Space Rocks, Aquatic Dinosaurs and Global Temperatures; 2020 science reviewed

    24/12/2020 Duración: 32min

    Nobody could have failed to notice the one story dominating the science news this year - but what about the discoveries that have been overshadowed in 2020? This week, Dr Adam Rutherford eschews all mentions of the pandemic as he invites dinosaur researcher Dr Susie Maidment, climate scientist Dr Tamsin Edwards and astrophysicist Dr Emma Chapman to share their science highlights of the year. We journey to the moon and beyond to discuss the many missions that have been blasting and grabbing bits of space rock to bring back to earth and tackle the ongoing debate about whether signs of life have been found on Venus. Back down on earth, this year could be one of, if not the, hottest years on record, with particularly high temperatures in the Arctic Circle. What might a warming world mean for ice-shelf collapse in Antarctica and how are governments responding? We discuss Joe Biden’s presidency, UK carbon emissions and what China’s recent announcements of net zero by 2060 might mean for the future of the planet. A

  • Covid mutation; On the facial expression of emotions; A mystery object

    17/12/2020 Duración: 33min

    Dr Alex Lathbridge with your peek at the week in science.This week in the House of Commons Matt Hancock announced a new variant in the Covid virus, discovered to be spreading through the south east of the UK. As Professor Jonathan Ball of the University of Nottingham describes, there have been many slight mutations and changes to the DNA in the virus since it first emerged, and most are of no added danger. But it is important that new ones - and new combinations of them - are tracked through collaborations and networks such as COG-UK, who provide an almost real-time track of the spread of new mutations. The new one this week is of some interest as it involves a slight change to the protein of the binding area on the virus, but much lab work remains to be done,Is an angry face always an angry face? A paper in the Journal Nature this week uses Machine Learning to scan millions of videos of faces on YouTube to shed light on an old problem - the universality of facial expressions in people. The authors - working

  • Future risk planning; Millennium Seed Bank; Urban trees

    10/12/2020 Duración: 36min

    Dr Alex Lathbridge brings you the week in science.As the first COVID vaccines are delivered this week hastening the first glimmers of a return to normal life, is it too soon to be thinking about other future threats to humanity? James Arbuthnot, chair of a House of Lords select committee tasked to look at risk planning, and fellow committee member Martin Rees discuss their meeting this week and the assessment of the scientists invited to share their interpretations of future threats like AI, solar flares and volcanic eruptions. They are inviting evidence submissions until January 28th 2021.The Millennium Seed Bank was setup as a safety net to protect and conserve rare, threatened and useful wild plants for generations to come. As it celebrates 20 years of operation it can claim to host 16 per cent of the world’s bankable flora in its sturdy underground vaults. Alex heads down to the Royal Botanic Gardens in Wakehurst, Sussex, and meets the team coaxing seeds to life to check their viability or using cryoprese

  • Protein folding; Hyabusa sample return; Holiday Covid testing

    03/12/2020 Duración: 36min

    Has one of the biggest problems in biology been solved by AI? Dr Alex Lathbridge brings you the week in science.This week google's Deep Mind team presented results of their latest efforts at cracking the 50 year old problem of Protein Folding. AlphaFold has built on previous success at predicting the 3D structures of biological proteins from just knowing the sequence of amino acids of which it is made. It is a computational problem that thousands of researchers around the world have been trying to solve for decades. There are millions of different proteins doing all the work in living cells, but simply knowing what their constituent chemicals are is not enough to understand how they are shaped, and therefore how they work. Scientists are optimistic that solving the problem will herald a new era in medicine, agriculture and even sustainable recycling. Prof John Moult, founding chair of CASP - the international body that monitors progress in the field, tells of the remarkable breakthrough being discussed this w

    Last weekend a joint European-US satellite blasted into space to begin its mission - monitoring the oceans back here on earth. Sentinel 6 Michael Freilich is one of a long line of satellites and has a striking design – appearing like a bright gold farmyard barn with a big pitched roof. Anand Jagatia speaks to Dr Ralph Cordey at Airbus Space and Defence about the latest design iteration and the technology on-board. Oceanographer Professor Penny Holiday from the National Oceanography Centre explains how Sentinel 6’s readings will enhance understanding of sea-level rises and give more detail about the currents in our oceans.We journey back to the cosmic ‘Dark Ages’, a period of time that we know hardly anything about. Dr Emma Chapman is an astrophysicist at Imperial College London who has written a book ‘First Light: Switching on Stars at the Dawn of Time’ to throw light on this illusive chapter in the history of our universe. How close are scientists to finding the first stars?With ambitious new government tar

  • COVID Operation Moonshot; Big Compost Experiment; Gulf of Mexico meteorite and new life

    19/11/2020 Duración: 30min

    Earlier this month, the government rolled out a pilot in Liverpool for ‘Operation Moonshot’, their proposal to spend £100 billion pounds to regularly test the entire UK population for SARS CoV 2. Anand Jagatia speaks to screening expert Dr Angela Raffle and medical test evaluator Professor Jon Deeks from the University of Birmingham. They share their concerns about the scheme and the benefits it may bring.A year ago, BBC Inside Science helped launch the Big Compost Experiment, a citizen science project run by a team at UCL. They asked the public to get involved by providing information about the matter that’s rotting in compost piles around the UK. What do people think about biodegradable plastics and what actually happens to them – do they break down like they are supposed to? Anand finds out about the results so far .from Mark Miodownik, one of the creators of this project, We travel back in time to 66 million years ago, when a massive meteorite smacked into the Gulf of Mexico bringing the reign of the dino

  • mRNA vaccinations; bacterial space miners; Artemis accords

    12/11/2020 Duración: 36min

    Scientists this week announced hopeful results in two of the big COVID-19 vaccination trials. Trudie Lang, Professor of Global Health at the Nuffield Department of Medicine, Oxford, describes some of the methodology used, what the efficacy statistic means, and how the novel approach of inserting mRNA rather than deactivated virus parts, is so exciting.Prof Charles Cockell has been investigating how bacteria might be grown in space on lumps of asteroid to extract precious minerals, and as Kim McAllister reports, his lab is itself in orbit.And it is just a few weeks since the UK, and several other countries, signed up to a set of bilateral agreements with the US called the Artemis Accords. These are an attempt to update previous outer space treaties on how countries - and indeed companies - might mine and use resources in space, given that no-one can currently legally claim sovereignty. As Dr Thomas Cheney of the Open University and Prof Jill Stuart of the LSE describe, the Accords have been greeted in certain

  • COVID in families; earthquake under Aegean Sea; Camilla Pang wins science book prize

    05/11/2020 Duración: 30min

    We know that children can catch the SarsCov2 virus, even though adverse side effects are incredibly rare. But what isn't clear is how likely they are to transmit the virus? If you’re a parent, are you in danger of catching the virus, maybe brought home from school by your child? A large study, using the anonymised health experiences of around 12 million adults registered with GPs in England, has just been published that explores that question. Dr Laurie Tomlinson, of London School of Hygiene and Tropical Medicine, explains the findings.On October 30th a magnitude 7 earthquake under the Aegean Sea created devastation when it struck Turkish city of Izmir. Marnie discusses the nature of the earthquake and why this area is so seismically active with Dr Laura Gregory, a geologist at Leeds University who has studied the rocks in the region. Professor Tiziana Rossetto, an expert in earthquake engineering at UCL, talks about a recent survey and intervention she carried out with the residents of Izmir to help them pre

  • A new saliva gland, Bill Bryson on the Human Body, and the return of the Dust Bowl

    29/10/2020 Duración: 34min

    Marnie Chesterton presents an update on the week's science.Behind your eyes, above your mouth but below the brain, two 3cm saliva glands have been hiding since anatomy began. So reports a new study by Matthijs Valstar and Wouter Vogel of The Netherlands Cancer Institute. They describe to Marnie how they found these hitherto unnoticed glands, and importantly how knowledge of these will help people treated for head and neck cancers to get on with their lives in the future. It may be that radiotherapies have been inadvertantly destroying the glands in the past, leading to difficulties eating and breathing. Bill Bryson is the latest in BBC Inside Science's flick through 2020's Royal Society Book Prize shortlisted authors. He talks to Adam Rutherford about his work, The Body: A Guide for Occupants, and his continuing awe at its complexity.And Roland Pease reports on evidence of a return to the Dust Bowl conditions that so devastated agriculture and livelihoods in the US mid-west during the 1930s.
