  • Coronavirus update, Typhoid Mary and 200th anniversary of the first sighting of Antarctica

    30/01/2020 Duración: 36min

    With the recent coronavirus outbreak spreading around the world, and concerns about people being infectious before they exhibit any symptoms. Professor of Virology at Nottingham University Jonathan Ball explains infection rates, quarantines and why he's worried about it spreading to the developing world. 'Alice in Typhoidland' is a new exhibition in Oxford recording how that city dealt with typhoid. It’s called that after one of its 19th century residents, Alice Liddell (the girl after whom Alice in Wonderland was named). Her father Henry Liddell was the Dean of Christchurch College and together with his friend Henry Ackland was instrumental in closing off Oxford's open sewers and thereby combating some of the causes of the disease. The exhibition also explores the fate of Typhoid Mary – one of the most famous asymptomatic disease carriers in history. Exactly 200 years ago, 30th January 1820, at 3:30 local time, the continent of Antarctica was spotted for the first time by a British expedition captained by

  • Coronavirus outbreak in China; Genetic diseases in Amish communities and getting an Egyptian mummy to speak

    23/01/2020 Duración: 31min

    With news reports moving as quickly as the virus may be spreading, the latest coronavirus outbreak which is thought to have started in Wuhan in central China is fast becoming a global health concern. Adam Rutherford speaks to BBC Inside Science's resident virologist Professor Jonathan Ball from Nottingham University, who says one of the most urgent things to do is to find out where the virus came from, and what animal it jumped to humans from. The Anabaptist Amish communities are some of the fastest growing populations on the planet. They came to the US from the Swiss-German border in the 18th and 19th centuries and have maintained their plain, simple community-minded way of life. Partly because they all descended from the same geographical area and partly because they tend to marry within their own communities, they can suffer from a particular spectrum of genetic disorders. Professor Andrew Crosby and Dr. Emma Baple from Exeter University have been studying these diseases, including a number new to medic

  • Reproducibility crisis in science; Aeolus wind-measuring satellite; electric cars

    16/01/2020 Duración: 30min

    Science is built upon the idea that results can be verified by others. Scientists do their experiments and write up their methods and results and submit them to a journal that sends them to other scientists, who check them and if they pass muster, the study gets published for further scrutiny. One of the keystones of this process is that results can be reproduced. If your results can’t be replicated, something is amiss. Over the last few years, particularly in the field of psychology, many high profile findings have not been reproduced. Now, the same problems that have plagued psychology are spilling over into other areas. This week, a study showed that ocean acidification does not significantly alter fish behaviour, as had been reported several times before. Adam Rutherford discusses the crisis with Matthew Cobb, Professor of Zoology at Manchester University. ESA’s Aeolus mission was launched in August 2018. It’s one of the European Space Agency’s Earth Explorer satellites. The Aeolus satellite uses lasers

  • Australian bush fires; Veganuary and LIGO

    09/01/2020 Duración: 31min

    2019 was the hottest and driest year on record in Australia. The Indian Ocean Dipole and the Southern Annular Mode weather systems, plus existing drought conditions, all primed the continent for the horrific fire season currently raging in the east and south east of the country. Climate scientist at the University of New South Wales Sarah Perkins-Kirkpatrick is in no doubt global warming played a role in making these the worst fires in recent history. Making matters even worse is that the ferocity of the bush-fires is creating its own weather. Nicholas McCarthy at the University of Queensland studies fire-induced weather and he explains how this can help spread the fires further. January is also Veganuary, a chance for you to try being vegan for 31 days. The reasons for giving up animal products in your diet are varied, from reducing your carbon footprint to not eating animals and getting healthy. Reporter Geoff Marsh is interested in the evidence in favour for and against a vegan diet. A signal in April

  • The hidden history in our DNA - Part 2 - Travel and Culture

    02/01/2020 Duración: 27min

    Our genomes are more than just an instruction manual for our bodies. They are maps, diaries, history books and medical records of our and our ancestor's lives...if you know how to read them. In the second part of BBC Inside Science's special, series, Adam Rutherford, UCL geneticist Lucy van Dorp and other scientists discover how travel and even culture of our ancestors can be decoded in our DNA today.

  • The hidden history in our DNA - Part 1 - Sex and Disease

    26/12/2019 Duración: 33min

    Our genomes are more than just an instruction manual for our bodies. They are maps, diaries, history books and medical records of our and our ancestors' lives.....if you know how to read them. In this programme and the next Adam Rutherford is joined by UCL geneticist Lucy van Dorp and other scientists who are cracking these genomic codes to tell the human story. This week they explore how sex and disease over the past few thousand years has left indelible marks on our DNA.

  • Ten years of Zooniverse; what happened to volcano Anak Krakatau and visualising maths

    19/12/2019 Duración: 30min

    Adam Rutherford talks to Chris Lintott about the citizen science platform he set up ten years ago. Zooniverse is a place where the public can help scientists analyse huge swathes of data. Projects such as spotting distant galaxies, counting penguins and tagging WW2 diaries have all has a huge boost thanks to the people-power of the Zooniverse. The Indonesian volcano Anak Krakatau, which means 'Son of Krakatoa', was born out of the ashes of the mega volcano which erupted and collapsed in the 1880s. Last year the island volcano Anak collapsed, causing a tsunami which killed 400 people. The collapse of millions of tonnes of rock into the ocean has now been mapped and chunks of rock, the size of office blocks, have been found tossed kilometres from the island. It really brings home how dangerous these volcanoes can be. BBC Inside Science producer Fi is always scribbling and doodling during interviews. It turns out she is a visual thinker and she compulsively draws the science being discussed. She is not alone:

  • Earliest hunting scene cave painting; animal domestication syndrome

    12/12/2019 Duración: 28min

    A cave painting in Sulawesi, Indonesia, has been dated and is at least 43,900 years old. The mural portrays a group of part-human, part-animal figures (called therianthropes), hunting large mammals with spears and ropes. It is thought to be the oldest representation of a hunting scene in human history, and perhaps Homo sapiens' oldest known figurative rock art. Adam Brumm at Griffith University in Brisbane is part of an international team that has been exploring this cave complex. He speculates with Adam Rutherford about who the artists were and what they were trying to depict. A famous Russian farm fox study has been running since the 1950’s. The researchers essentially took foxes bound for the fur trade and selected for tameness by choosing to keep and breed from the animals that showed less fear and more friendliness towards humans. After years of selection, the tamer foxes also showed physical changes (floppier ears, curlier tails, white spots, redder fur) as well as changes in breeding times. As a way

  • Global Carbon Emissions; Parker Solar Probe and simulating swaying buildings

    05/12/2019 Duración: 31min

    Reports from the UN Climate Change Conference (COP 25) in Madrid are saying that global warming is increasing and that we're not doing enough, fast enough, to change things. The World Meteorological Organisation's provisional State of the Climate 2019 report lists atmospheric carbon dioxide reaching record levels. Global mean temperatures for Jan-Oct 2019 were 1.1+/-0.1 degrees Celsius above pre-industrial levels. The Arctic ice extent minimum in Sept 2019 was the second lowest on satellite record. Tropical cyclone Idai was the strongest cyclone known to make landfall. These are all concerning statistics. According to the Global Carbon Emissions figures that have just been released, carbon dioxide in the atmosphere is still increasing: the slightly good news is that the rate of increase has slowed. Adam Rutherford talks to climate expert at the Tyndall Centre at the University of East Anglia, Corinne Le Le Quéré, to find out more. “Safe as houses" is a cliché built on the solidity of the buildings we put up.

  • What's the problem with palm oil and should we be supporting sustainably grown oil? Virtual reality skin

    28/11/2019 Duración: 29min

    Palm oil is now such a dirty word for household products and processed food, that it often hides behind a list of dozens of pseudonyms (from the ubiquitous sodium laureth sulphate to the slightly more obvious palm kernel oil, to the totally opaque vegetable oil). It’s becoming a major global concern, and there is on going debate between enforcing a ban or shifting to more sustainable production. It’s always complicated, but as we’ve learned so many times in the past, we have to tread carefully to avoid the unintended consequences of making snap environmental decisions. Indications that an outright ban might be more environmentally harmful because of the lower yield and more land needed by alternative vegetable oil crops, so should we be paying more attention and even championing sustainably sourced palm oil? In the UK, Chester has become the first city to source its palm oil entirely from sustainable sources. Cat Barton and Simon Dowell from Chester Zoo have recently returned from the EU where they were advis

  • Noise pollution and wildlife; No till farming; Cornwall's geothermal heat

    21/11/2019 Duración: 37min

    The effects of human-made noise on the natural world has been surprisingly little studied. Hanjoerg Kunc at Queen's University in Belfast has collected all experimental data on the effects of anthropogenic noise on wild animals and found it to be overwhelmingly harmful., And Cambridge University's PhD student Sophia Cooke is looking at the impact of roads, including road noise on British birds, and the impact could be huge. Last week we spoke to Jane Rickson at Cranfield University about how healthy soils are a good defence against the effects of, and indeed the process of, flooding. Many farmer listeners emailed in to tell us about their experiences with no till and minimum disturbance agriculture. Simon Jeffery at Harper-Adams University takes Adam through some of the points raised. Last November, drilling began in Redruth, Cornwall to see if geothermal heat could be tapped from the hot rocks below. Graihagh Jackson went to catch up with the project and met with Lucy Cotton – the project geologist for the

  • Soils and floods, Air pollution and ultra-low emission zones, detecting the drug Spice

    14/11/2019 Duración: 29min

    The UK's soils are the first line of defence against flooding, but the condition of the soil is vital to how well it can soak up and slowly release rainwater. Jane Rickson, Professor of soil erosion and conservation at Cranfield University, explains to Adam what makes a healthy soil and what farmers can do to try to prevent floods. "Spice" is a catch-all phrase for a large variety of psycho-active compounds - commonly called legal highs. They interact with the same receptors in the brain as cannabis does. They're commonly sold sprayed onto common herbs that users smoke, so that dose, as well as variety and purity are completely uncontrolled by the time they're taken. And that's where the problems start in A&E departments and the blue-light services, because patients can show up with severe symptoms of psychosis with little clue as to what's caused it. And until now there's been no quick and easy test. Roland Pease went to Bath University where biochemist Chris Pudney and his team have developed some portab

  • Fracking moratorium; Bloodhound; Big Compost Experiment; transit of Mercury

    07/11/2019 Duración: 28min

    The Prime Minister Boris Johnson announced an indefinite moratorium this week on mining of shale gas by hydraulic fracturing, aka fracking, in the UK, citing fears of earthquakes and seismic activity caused by fracking in the past. In August this year, a 2.9 magnitude earthquake was recorded at the Preston New Road fracking site in Lancashire, which prompted an immediate shutdown, as required by the strict protocols that we have in place. Adam Rutherford talks to Dr James Verdon, a geophysicist at Bristol University and a co-author of one of the Oil & Gas Authority studies on the Preston New Road, about the science of fracking. Bloodhound is the latest British attempt at the supersonic land speed record. All this week Wing Commander Andy Green has been burning across a dried out lake in the Kalahari Desert, as he and his team are building up to break the sound barrier at 740mph, and his own land speed record of 763 mph. BBC science correspondent Jonathan Amos reports from the trackside. The Big Compost Ex

  • African genomes sequenced; Space weather; sports head injuries

    31/10/2019 Duración: 29min

    Since the human genome was first sequenced nearly 20 years ago, around a million people have had theirs decoded, giving us new insights into the links between genes, ancestry and disease. But most of the genomes studied have been in people of European descent. Now a decade-long collaboration between scientists in the UK and in Uganda has created the largest African genome dataset to date. Dr Deepti Gurdasani discusses her research with Gaia Vince. After 7 years of orbiting the Earth and sending us important information about space weather, NASA’s Van Allen Probes are retiring. Professor Lucie Green from UCL explains how the sun can spit out superhot plasma and streams of high energy particles in our direction. We are mostly protected by the Earth’s magnetic field - but not always. The worst-case scenario is that the radiation could disrupt navigation satellites and bring down electrical power supplies. Professor Green will be keeping an eye on space weather with a new spacecraft. Growing evidence shows t

  • Organic farming emissions; Staring at seagulls; Salt and dementia

    24/10/2019 Duración: 27min

    Switching to 100% organic food production in England and Wales would see an overall increase in greenhouse gas emissions. Although going fully organic would produce fewer direct emissions than conventional farming, researchers say it would limit food production. Making up the shortfall with imports from overseas would increase overall emissions. But is the sustainability of our food production about more than greenhouse gas emissions alone? Professor Dave Reay is Chair in Carbon Management & Education at the University of Edinburgh, and has recently acquired a smallholding in Scotland. He discusses the study and answer your questions about sustainable food and population growth. Seagulls have become notorious food thieves in recent times as they move into towns to find new habitats and sustenance. Scientists at the University of Exeter have found that if you stare at a herring gull, it’s much less likely to steal your chips. Reporter Graihagh Jackson went to Falmouth to meet with researchers Madeleine Goumas

  • Ebola model, Partula snails, Malaria origin

    17/10/2019 Duración: 27min

    Zoonotic diseases are infections that transfer from animals to people, and include killers such as bubonic plague, malaria, ebola and a whole host of others. Trying to understand how diseases make the leap from animals to humans – so called spillover – and how outbreaks occur is a crucial part of preventing them. But outbreaks are complex and dynamic, with a huge number of factors playing a role: What animal is hosting the disease, the environment in which it lives, the changing climate, human presence and impact on the local area and many other factors. Kate Jones is professor of ecology and biodiversity at University College London, and has been tracking ebola in Africa. Her team has just published a new study that models how and when spillover might happen in the future. On the lushly forest islands of French Polynesia, there lives a very special snail. Partula are around 100 species of tiny snails who give birth to live young and feed on decomposing plants. Each species is uniquely adapted to a particul

  • Extinction Rebellion, UK net zero emissions and climate change; Nobel Prizes

    10/10/2019 Duración: 27min

    Extinction Rebellion is in the news with its stated aim of civil disobedience and protest, and goal to compel governments around the world to act on the climate crisis. Meanwhile, the UK government this week announced that it was overruling its own Planning Inspectorate, by approving in principle new gas-fired turbines at the Drax power station in North Yorkshire. The Inspectors had advised that the new developments would undermine UK climate policies on carbon emissions. In the UK we are committed to reaching net zero carbon emissions by 2050, in order to comply with our ratification of the Paris agreement, which aims to limit global temperature rise to 1.5 degrees. So what are we to do? Are the government policies and commitments enough, and are we sticking to them? Adam Rutherford discusses these questions with Jim Skea, Professor of Sustainable Energy at Imperial College, London, and co-chair of the Working Group tackling reducing emissions of greenhouse gases, part of the Intergovernmental Panel on Clima

  • HIV protective gene paper retraction, Imaging ancient Herculaneum scrolls, Bill Bryson's The Body

    03/10/2019 Duración: 35min

    In November 2018 news broke via YouTube that He Jiankui, then a professor at Southern University of Science and Technology in Shenzhen, China had created the world’s first gene-edited babies from two embryos. The edited gene was CCR5 delta 32 - a gene that conferred protection against HIV. Alongside the public, most of the scientific community were horrified. There was a spate of correspondence, not just on the ethics, but also on the science. One prominent paper was by Rasmus Nielsen and Xinzhu Wei’s of the University of California, Berkeley. They published a study in June 2019 in Nature Medicine that found an increased mortality rate in people with an HIV-preventing gene variant. It was another stick used to beat Jiankiu – had he put a gene in these babies that was not just not helpful, but actually harmful? However it now turns out that the study by Nielsen and Wei has a major flaw. In a series of tweets, Nielsen was notified of an error in the UK Biobank data and his analysis. Sean Harrison at the Univer

  • Oceans, ice and climate change; Neolithic baby bottles; Caroline Criado-Perez wins RS Book Prize

    26/09/2019 Duración: 35min

    The Intergovernmental Panel on Climate Change's special report on the oceans and cryosphere makes pretty grim reading on the state of our seas and icy places. Ocean temperatures are rising, permafrost and sea ice are melting, sea levels are rising and marine life is either moving or suffering the effects of temperature changes and acidification. Dr Phil Williamson, research fellow at the University of East Anglia, worked on the report and he explains to Adam Rutherford how the watery and icy parts of the planet connect to the atmosphere and climate. It's a good job the small, round, spouted clay vessels found in 3000 year old baby graves in Bavaria weren't washed up very well. Crusts of food deposits have shown that these early baby bottles were used to give infants milk from ruminants such as cows, goats and sheep. This discovery, and previous discoveries of even earlier spouted vessels in Europe, indicate that settling down from hunter-gathering to agriculture in prehistoric Iron and Bronze-Age people im

  • MOSAiC Arctic super-expedition, Likely extinction of the Bahama nuthatch, Tim Smedley's book on air pollution

    19/09/2019 Duración: 30min

    On Friday, 20 September, a powerful icebreaker called The Polarstern will set sail from Tromsø, Norway, with the aim of getting stuck into the polar ice. The plan is for the ship to spend the next year drifting past the North Pole, and this should enable scientists to collect unprecedented data on the Arctic. The Polarstern is the ‘mothership’ of a substantial international collaboration called the Multidisciplinary drifting Observatory for the Study of Arctic Climate (or project MOSAiC). Scientists from over seventy research institutions across 19 different countries are involved, and a total of six hundred experts will be aboard throughout the expedition. They plan to construct a ‘research city’ around the vessel with different neighbourhoods, each focused on a particular scientific area including: ecosystem, bio-geo-chemistry, ocean, atmosphere and sea ice. Adam spoke to UCL’s Professor Julienne Stroeve, who will be aboard The Polarstern for two months during the Arctic winter, looking at the depth and den
