The world’s oldest fossilised forest was uncovered in Somerset last week. We head to palaeobotanist, Dr Christopher Berry’s, lab at Cardiff University to learn about these cladoxylopsids. They lived 390 million years ago and although they are not the ancestors of today’s trees, they reveal some extraordinary evolutionary secrets. Also, Marnie speaks to Dr Chris Thorogood of the University of Oxford Botanic Gardens about his new book Pathless Forest: The Quest to Save the World’s Largest Flowers. Called “Rafflesia” plants and found in the remotest parts of South East Asia, their flowers burst from the rain forest floor the size of pumpkins and are critically endangered. Chris talks of his world of extreme fieldwork and hair-raising expeditions, braving leeches, lizards and lethal forest swamps, to discover the rarest of rare blooms. Plus, the Wildlife Trust’s Making Friends with Molluscs campaign starts today, and I’m sure many gardeners will declare this an impossible task! We visit some allotments in Bristol to find out how people are managing slug and snail populations. And chat to Brian Eversham from the Trust of Bedfordshire, Cambridgeshire and Northamptonshire, who explains why these garden creatures should be considered our friends, not foes. And finally, Dr Stewart Husband from last week’s programme returns to answer more of your burning questions about your tap water.

A recent study on how to get rid of microplastics in water sparked presenter Marnie Chesterton’s curiosity. When she turns on the tap in her kitchen each day, what comes out is drinkable, clean water. But where did it come from, and what’s in it? Dr Stewart Husband from Sheffield University answers this and more, including listener questions from around the UK. Is water sterile? Should I use a filter? And why does my water smell like chlorine? Also, new research indicates that bumblebees can show each other how to solve puzzles too complex for them to learn on their own. Professor Lars Chittka put these clever insects to the test and found that they could learn through social interaction. How exactly did the experiment work, and what does this mean for our understanding of social insects? Reporter Hannah Fisher visits the bee lab at Queen Mary University in London. And finally, more than 20 million years ago, our branch of the tree of life lost its tail. At that point in time, apes split from another animal group, monkeys. Now, geneticist Dr Bo Xia at the Broad Institute of MIT and Harvard thinks he may have found the specific mutation that took our tails. Marnie speaks with evolutionary biologist Dr Tom Stubbs from the Open University about why being tail-less could be beneficial. What would a hypothetical parallel universe look like where humans roam the earth, tails intact? And what would these tails look like?

Switzerland has submitted a proposal to create a United Nations expert group on solar geoengineering to inform governments and stakeholders. The idea was discussed at the UN Environment Assembly in Nairobi, Kenya, this week. Professor Aarti Gupta shares how, after tense negotiations, the different member states could not agree, and the proposal was withdrawn. Why is solar geoengineering a controversial issue? How would dimming the sun even work? And should we consider it a genuine option in our fight against climate change? Dr Pete Irvine and Professor Joanna Haigh join presenter Marnie Chesterton in the studio to discuss. Animal welfare charities have been celebrating a ban on donkey skin trade, agreed to this month by 55 African countries. This will make it illegal to slaughter donkeys for their skin across the continent, where around two thirds of the world’s 53 million donkeys live. Victoria Gill tells Marnie that the demand for the animals' skins is fuelled by the popularity of an ancient Chinese medicine called Ejiao, believed to have health-enhancing and youth-preserving properties and traditionally made from donkey hides. Lastly, Dr Jess Wade, physicist and science communicator at Imperial College London, discusses Breaking Through: My Life in Science. It’s the memoir of Nobel Prize-winning biochemist Dr Katalin Karikó, whose passion and dedication to mRNA research led to the development of the life-changing COVID mRNA vaccines.

Professor Ben Garrod guest presents. As a new 'meaty rice' is created and Fortnum & Mason launch a scotch egg made with cultivated meat that they hope to have on sale as early as next year, we investigate the world of laboratory-grown meat. Mark Post made the first ever synthetic meat in 2012 to the tune of £200,000. He tells us how these lab-grown meats are made and how, he thinks, they could play an important role in reducing greenhouse gas emissions and feeding a growing population. Jenny Kleeman, author of Sex, Robots and Vegan Meat, is more sceptical, citing concerns over food security and if the public really want to eat this stuff. A stingray called Charlotte has become pregnant, despite there being no other stingrays in her tank at the Aquarium & Shark Lab in North Carolina. Marine biologist Dr Helen Scales considers how this may have happened. And cosmic minerologist Sara Russell from the Natural History Museum tells us how astronomers tracked and found a particularly unusual asteroid entering Earth’s atmosphere and what we might learn from it.  Presenter: Professor Ben Garrod Producers: Hannah Robins, Florian Bohr, Alice Lipscombe-Southwell and Jonathan Blackwell Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth  BBC Inside Science is produced in collaboration with the Open University.

The Gulf Stream, also known as the Atlantic Meridional Overturning Circulation (AMOC), is essential to stable global climate, and the reason we have moderate temperatures in Northern Europe. Now, a new modelling study suggests that this circulation could, at some point, be at a tipping point and collapse. We hear from one of the minds behind the model, post-doctoral researcher René van Westen from Utrecht University. But how likely is it that this will actually happen in the real world? Presenter Victoria Gill speaks to Jonathan Bamber who cautions that a gulf stream collapse is not imminent, and that it may just weaken slowly over time. Every summer in the Hudson Bay, on the Eastern side of Arctic Canada, the sea ice melts and the region’s polar bears head inland. But that ice-free season is getting longer, depriving the bears of that frozen platform that they use to pounce on their favourite prey – seals. So what do the bears do all summer? Research Wildlife Biologist Karyn Rode shares how she and her colleagues put a collar with video cameras on 20 polar bears, and what it revealed about their lives. Is CERN finally going to get a gigantic new particle accelerator? Almost exactly one decade ago, Roland Pease reported from Switzerland about the very first meeting about the successor of the Large Hadron Collider which was used to discover the Higgs Boson. Now there’s an update to the story. Roland is back to tell Vic how far along CERN is with their plans, and how much more time and money it will take to build the Future Circular Collider. Lovers of certain famous, creamy French cheeses could be in for a bit of a shock. Camembert and Brie are facing extinction as we know them! The Centre National de la Recherche Scientifique (CNRS) in Paris has stated that, over the last 100 years, the food and farming industry has placed too much pressure on the production of these types of cheeses. Now, the fungus traditionally used to grow the famous, fluffy white rinds has been cloned to a point where the lack of diversity in its genetic makeup means it can no longer be reproduced. Turophiles must learn to appreciate more diversity of tastes, colours and textures to protect the cheeses’ future.

As part of the Vesuvius Challenge, computer scientists have used machine learning to successfully reveal 2,000 characters from the Herculaneum scrolls. These artefacts were charred to a crisp following the eruption of Vesuvius in 79 AD. Papyrologist Federica Nicolardi has been translating the writings, and tells us what exactly has been deciphered. Following this week’s launch of NASA’s PACE satellite, NASA scientist Dr Susanne Craig tells us how the mission will be giving our planet a health check. Bird flu is still an issue. This month, scientists have reported that hundreds of penguin chicks have died from the virus in the Falklands. Meanwhile, in Argentina, avian flu has killed huge numbers of elephant seal pups. Professor Wendy Barclay, a virologist from Imperial College London, tells us more about the virus and how it can jump between species. Sunday 11th February is International Day of Women and Girls in Science. Physicist Dr Jess Wade, who has written hundreds of Wikipedia biographies of women and underrepresented scientists, reveals one of her favourite scientists that people haven’t heard of.

Are cyborgs now reality? Elon Musk certainly thinks so. His company, Neuralink, has successfully implanted one of its wireless brain chips in a human. Although billed as a breakthrough, they’re not the first to do it. In fact, similar devices have already been implanted, all with the aim of connecting our brains to computers with the aim of tackling complex neurological conditions. Joining Inside Science is neuroscientist and author, Dean Burnett. In this episode, Dean helps to break down the technology behind the brain-computer interface and digs into the ethical implications. Plus, game changing smart technology gets a run out as Rugby Union’s Six Nations Championship kicks-off. This year, all players will be wearing “Smart Mouth Guards.” These are intelligent gum shields containing miniature gyroscopes, accelerometers and Bluetooth, which provide - with incredible accuracy - a measure of the magnitude and frequency of forces experienced by players. An athlete making their international debut in this competition could have their entire collision history mapped from now until retirement, providing invaluable information for training and treatments. Crucial not only for elite squads, but ultimately for community and schools rugby where the technology will eventually land, leading to a safer game. And finally, it turns out that we can actually understand chickens even if we’ve never met them before! After assessing a group of around 200 volunteers, a team at the University of Queensland has discovered that humans with no experience of chickens at all, could understand the birds’ calls of satisfaction, or frustration. The research has serious implications for what’s known as precision farming, an area of livestock farming with little, to no, human interaction that requires automated systems of welfare detection using sound recognition.

Hydrogen has long been touted as a potential wonder gas that could play a significant role in our race to net zero. Now, planning permission has been granted for the UK’s largest production hub of its kind, and one of the most advanced in the world. Located in Cheshire, it bills itself as a vital piece of Northwest England’s mission to help manufacturers in the region decarbonise their processes and support UK jobs. We speak to chemical engineer and the plant’s site manager, Richard Holden, and we also catch up with Mark Miodownik, Professor of Materials and Society at University College London, about hydrogen and our future energy economy. Almost 25 years ago, Dr Marc Lammers stumbled across a mystery. The humpback whale singing he was recording via an underwater microphone near the shore was quieter during the day than at night. But he wasn’t able to answer why. Many years later, a PhD student, Anke Kuegler, joined his research team and took on the task of uncovering what was really going on. Using multiple ways of listening to and tracking the whales, she found out that the singing humpbacks were moving off-shore during the day, and closer to shore at night. Part of the mystery was solved, but it raised an even bigger question: what is driving this behaviour? Plus, a recent study has shown that terrestrial hermit crabs around the world are using non-organic materials, like plastic bottle caps, as their homes. Professor Marta Szulkin and her team at the University of Warsaw looked through social media photographs and videos (known as iEcology, or Internet Ecology) to find evidence for this new behaviour. Marta has theories about why the crabs are doing this, but it will take many years of research to uncover the long-term effects on hermit crab populations and their evolutionary trajectory. And, resident materials expert, Mark Miodownik, chats to Viv about what we can, and cannot, solve about the global plastic emergency.
