BBC Inside Science

This week, we hear from the University of Florida’s Dr David Duffy. He heads up a team of researchers who are studying sea turtles. In order to track the animals and their diseases, the scientists devised a method of collecting fragments of DNA from tanks at the university’s turtle hospital, as well as from sand and water in the local environment. While they found plenty of turtle DNA, they were surprised to uncover large amounts of high-quality human eDNA. Duffy tells us all about the study and his surprising findings, but also highlights the ethical problems this could raise. We are then joined by Dr Matt Clark from the Natural History Museum, and Sir Jonathan Montgomery from University College London, to discuss the ins and outs of eDNA – how it can be beneficial for conservation, forensics and healthcare, but could also be problematic from a privacy perspective. Muriel Rabone and Dr Adrian Glover from the Natural History Museum have compiled an extensive checklist of all the species present in the remote Clarion-Clipperton Zone, which is an area twice the size of India, five kilometres deep in the Pacific Ocean. While you might expect this part of the sea to be devoid of life, the organisms that live there are surprisingly diverse, and we still know little about them. But the region is also chock-full of in-demand rare-earth metals. And we are joined by Dr Katie King to talk over some of her favourite science stories of the week, followed up by Helen Keen, who gets the kettle on to reveal more about the surprising physics behind a cup of coffee. Milk and two sugars for us, please. Presenter: Gareth Mitchell Producer: Hannah Fisher Content Producer: Alice Lipscombe-Southwell

The Royal Society is the oldest scientific academy in the world. Since being established in 1660, it has painstakingly archived thousands of papers, letters, manuscripts and illustrations from some of science’s most enquiring minds.In this episode, Victoria Gill takes a trip to the society to pore over some of the most intriguing artefacts within its vaults. While there, she finds out more about the formation of the Royal Society and how science has been shaped over the centuries. Along the way, she considers the role of women in science, and asks whether their contributions have been historically overlooked.She is joined by the Royal Society’s Louisiane Ferlier and Keith Moore, along with Prof Uta Frith, a Royal Society Fellow and psychologist, and Dr Stephen Webster, a senior lecturer in science communication at Imperial College London. As part of its Science in the Making project, the Royal Society is currently digitising all of its collections, for everyone to browse through and enjoy. You can find out more on the Royal Society website.Presenter: Victoria Gill Producers: Harrison Lewis, Hannah Fisher Content Producer: Alice Lipscombe-Southwell

Natural disasters such as earthquakes, tsunamis, volcanoes and hurricanes all have the power to cause deadly destruction. One event can lead to another, causing a chain reaction of devastation that can take years to rebuild from. But do all natural events have to turn into a disaster? Is there anything we can do to mitigate their impacts? Gaia Vince speaks to Anastasios Sextos, Professor of Earthquake Engineering at the University of Bristol to find out how we can engineer buildings to withstand earthquakes, and Bruce Malamud, Executive Director of the Institute of Hazard Risk and Resilience at Durham University, to learn how we can build models to forecast the risk of a natural disaster occurring. Lucy Easthope is a leading advisor on emergency planning and disaster recovery and a Professor in Hazard and Risk at Durham University. She joins Gaia in the studio to discuss her experience of being one of the first responders to disasters and how in fact, the way they unfold is more predictable than we might think. Ilan Kelman, Professor of Disasters and Health at UCL, also joins them to discuss the importance of social resilience, long-term planning and effective alert communication in managing and mitigating the aftermath of these events.

In 2020, the UK government committed to protecting at least 30% of land and sea for nature by 2030. Step seven years into the future with Gaia. The UK has achieved its biodiversity goal, but what does wild Britain look like? Richard Benwell, CEO of wildlife and Countryside Link, Meredith Whitten, a researcher and urban environment planner at LSE, Hugo Tagholm, CEO of Oceana and George Monbiot, an environmental writer whose book Regenesis explores sustainable agriculture, describe this radical new world.

James Watson and Francis Crick, who detailed the double-helix structure of DNA in 1953, are perhaps two of the most iconic scientists of the 20th Century. Yet the story of how they made their incredible discovery is perhaps equally famous, with a notorious narrative suggesting that they only identified the structure after taking the work of Rosalind Franklin and using it without her permission. Now, 70 years after the discovery of DNA’s structure, it is perhaps time to rewrite the tale. New evidence has now been unearthed, in the form of an overlooked news article and an unpublished letter, that shows that Franklin was truly an equal contributor to the discovery, and Watson and Crick were not as malicious as previously assumed. Together with Matthew Cobb of the University of Manchester, Nathaniel Comfort from Johns Hopkins University, and Angela Creager of Princeton University, Gaia Vince discusses this tantalising tale and finds out more about how this discovery could bring a whole new twist to the story of DNA.

Whilst the globe struggles to shift to green sustainable energy sources, one industry has its sights set solely on the stars. Space X just launched the biggest rocket the world’s ever seen, and it won’t be their last even if it did end its test flight with a bang. As we enter a new golden age of space travel, Vic asks Associate Professor in Physical Geography Dr Eloise Marais if we are paying enough attention to the environmental impacts posed by a rapidly growing space industry. Have viruses, bacteria, and microorganisms influenced humanity more than we know? Author of new book, Pathogenesis: How Germs Made History, Dr Jonathan Kennedy discusses how germs and disease have shaped human evolution, history and culture and what we can learn from the COVID pandemic. And from unconventional life in space to psychoactive spinning apes, Vic and BBC Climate Reporter Georgina Rannard bring you the best scientific stories from the past couple of weeks. Presenter: Victoria Gill Producer: Harrison Lewis Content Producer: Ella Hubber BBC Inside Science is produced in collaboration with the Open University.

When was the last time you had to use your negotiating skills? Did you walk away satisfied? This week junior doctors are half way through their 4 day walkout, with senior NHS figures suggesting the cancellation of between 250,000 and 350,000 appointments/operations. Victoria Gill is preparing to debate her way through the science of disagreement and identify what qualities make for the perfect negotiator. Associate Professor Sunny Lee, Deputy Director of Equality, Diversity, and Inclusion at University College London helps guide Victoria through the basic building blocks that help resolve conflict, with expert commentary from Camilla Born peeking behind the curtain of COP26, and finally negotiating with elephants? Dr Josh Plotnik at City University of New York suggests that some animals may be actively seeking out conflict with humans.Presenter: Victoria Gill Producer: Harrison Lewis

In this special edition of Inside Science, Vic Gill prepares to rummage through our rubbish, to peek behind the curtain of the UK's recycling habits and see how well prepared we are as a nation to further our efforts of sustainable waste management.Presenter: Vic Gill Producer: Emily Bird

Far away and not enough, those are criticisms of the government’s latest net zero initiative – a plan to reduce emissions . We ask Jim Watson Professor of Energy Policy and Director of the UCL Institute for Sustainable Resources for his assessment.And there’s money to be made from private health testing, the growth of Covid testing has been followed by an upsurge in private screening for cancer in particular, but how useful is it really? BBC Health correspondent Matthew Hill takes a look.Every cell in out body carries an electrical charge. In her new book, We Are Electric: The New Science of Our Body’s Electrome, Sally Adee discusses how this facet might be harnessed for the detection of illnesses, medical treatments and whether it will allow us to develop hidden powers.The World Wood Web is a concept showing how trees communicate with each other through an underground fungal network. The idea was first proposed by Suzanne Simard, Now professor of Forest Ecology at the University of British Columbia, who tells us how she came up with the concept and about her work on the hidden relationships of trees.

Data collated from swab samples taken in Wuhan’s market in the early days of the Covid pandemic suggest animals sold in the market were carrying the virus at the time. It’s the strongest evidence yet for an intermediate species – one which passed the virus on to humans after becoming infected by bats carrying the virus. Dr Florence Debarre from the Institute of ecology and environmental sciences, in Paris and Professor Eddie Holmes from Sydney University discuss the findings. Beethoven’s genome has been reconstructed from samples of his hair. It reveals some of his medical history, but also unexpected findings on his paternity. We discuss the ethics of such genetic analysis with Tom Booth who studies ancient DNA at the Francis Crick institute. And microbes may help us survive and thrive in space according to Astrobiologist Rosa Santomartino, not only that but their recycling capabilities could also help us on earth
