BBC Inside Science

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 long been cited as the classic example of an effective international agreement to protect earth's environment. But just a few years ago in 2018 Luke Western and colleagues identified not just that CFC production was suddenly and unexpectedly rising, but that it was mainly emanating from an area in eastern China. It was speculated then that their use in foams for buildings was happening illicitly on a large scale. This week, they happily announce that those emissions seem to have ceased, and that the target of a healthy ozone layer is back on track.The oceans are, since man first took to the waves, a noisy place. In a comprehensive paper published last week in the journal Science Carlos Duarte and colleagues describe how huge an impact the many anthropogenic noises that echo for miles across the sea beds have on virtually all aquatic life. He argues that it is one stressor, rather like CFCs, that we could and should take swift and effective action to address, that the time for that is ripe, and that doing so will see a swift rebound in many aquatic ecosystems. Humans are not naturally adapted to hear the noise underwater, but to illustrate the point, co-author digital artist Jana Winderen has made an acoustic demonstration for your benefit, of quite how noisy neighbours we areAlso, for listeners on BBC Sounds, the BBC's Roland Pease gives an update on where and how scientists think the covid-19 epidemic began, after a WHO team of scientists report on their recent mission to Wuhan and the infamous market. As Roland and WHO delegate Peter Daszak surmise, we still don't quite know, but it wasn't in a lab.Presented by Victoria Gill Produced by Alex MansfieldMade in Association with The Open University.

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" minerals and metals from soils. BBC Inside Science's Harrison Lewis reports how, after some intrepid botany, the idea might just now be bearing heavy fruit.But finding the plants that do some of what you want them to does not mean they should be planted just anywhere. Lulu Zhang from United Nations University in Dresden, Germany tells Victoria about the Chinese experience of a few decades ago when the Black Lotus tree seemed to be just the ticket for newly foresting huge areas of China to stabilize and neutralize soils. Unfortunately, nobody realized how thirsty the monocultured forest would be, and the thirsty trees deprived the area of much of the rainwater from humans and agriculture.Meanwhile this week scientists have published work looking at how even the noise from traffic on the roads can disrupt animal behaviour. Chris Templeton of Pacific University in Oregon has been studying how some bird's cognititve abilities can be affected. And Adam Bent describes work at Anglia Ruskin University into how crickets' mating choices can be adversely affected by recordings of the A14 near Cambridge.Presented by Victoria Gill Produced by Alex MansfieldMade in association with The Open University

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 Anglia Ruskin University describes in Science Advances work he has done looking at certain kinds of development in children who grow up in bilingual households. His work suggests a slightly faster and keener observation of detailed changes in visual cues, and that this seems to be a trait that survives into adulthood.

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' reaction to a warming climate over coming decades. It's not very comforting, with increased duration and intensity of what he calls "Lake Heatwaves".Presented by Alex Lathbridge Produced by Alex MansfieldMade in associataion with the Open University.Note: This podcast has been edited since the original broadcast to prevent any possible inference that the Tuskegee syphilis study involved the deliberate infection of subjects. In the Tuskegee study, African American patients who were already infected with syphilis had diagnosis and treatment deliberately withheld from them in order to observe the progression of the lethal disease over several decades (even after a perfectly simple treatment - penicillin - became available).

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 Stefansson's company Decode Genetics analyze the genetic codes of most of the population of Iceland. This has allowed them to look at the parents, siblings, and offspring of identical twins, and identify how early genetic differences between them develop. And it's very early indeed. Given that identical twins studies are so often used to address issues surrounding the so-called Nature-vs-Nurture debate, the findings, published in the Journal Nature, are striking.

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 relying on such things as solar powered audio recorders to measure biodiversity in the sounds of the wild. But how to scrutinize years and years worth of 24 hour, multi-site recordings? Sarab Sethi and colleagues have not only been leaving solar-powered Raspberry Pi recorders out in the jungles of Borneo, they've been using machine learning techniques to look out for species and biodiversity changes from afar. You can listen to some of the Borneo work at the SAFE acoustic website (link on BBC page below).Presented by Marnie ChestertonProduced by Alex MansfieldMade in collaboration with the Open University.

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.

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. And despite limitations on travel this past year, exciting discoveries in the dinosaur world have nonetheless continued with what is believed to be the first aquatic dinosaur. The detection of soft shell eggs is also changing understandings of how dinosaurs reared their offspring.And if that wasn’t enough, Dr Adam Rutherford challenges our experts to predict what big science stories might lie on the horizon in 2021.

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 with Google - suggest that broadly speaking, in a number of contexts such as weddings and sporting events, people in much of the world tend to pull the same faces. But as Lisa Feldman Barrett - who wrote an accompanying commentary in the same journal - suggests, the way Machine Learning approaches in this area require very human perceptions to train the algorithm in the first place, means care must be taken before inferring too much.This year BBC Inside Science has been showcasing some of the mystery objects the Science Museum has uncovered in the course of moving its collections to a new home in Wroughton, Wiltshire. Jessica Bradford talks to Alex about our next one. If you have any ideas what it might be for, you can let them know by dropping a note or memory to mysteryobject@sciencemuseum.ac.uk Presented by Alex Lathbridge Produced by Alex MansfieldMade in Association with The Open University

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 cryopreserving on those seeds less convivial to being preserved. One key project is protecting farmed crops that have lost genetic diversity over time and are at risk from climate change. Through collecting and researching the wild ‘cousins’ of our modern day crops Wakehurst, Kew Gardens and its partners are researching and harnessing the resilient traits found in these less pampered crop relatives. Treezilla.org is a citizen science project designed to increase understanding of all the urban tress in the UK. Scientists, together with the public, are getting their tape measures out and cataloguing the trees to better ascertain how they influence the environment in towns and cities across the UK, to map their ages, species, sizes and health, and to help future planners to put the knowledge to work. Kate Hand is a researcher at the Open University who is looking at ways to increase our knowledge of the values trees bring to our urban environments – specifically through the lens of Milton Keynes which, it transpires, is quite the urban arboretum.
