  • 662 - The Gulf Stream’s tipping point

    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.

  • 661 - Ancient Roman writings revealed

    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.

  • 660 - When brains and computers meet

    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.

  • 659 - Hydrogen and the race to net zero

    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.

  • 658 - A New Volcanic Era?

    As lava consumes homes on the Reykjavik Peninsula in Iceland, evacuated communities have been witnessing eruptions shifting and intensifying. We take a look at the latest science that’s helping teams on the ground accurately predict where the danger is coming from, helping people to stay safe. Our go-to volcanologist, Dr Evgenia Ilyinskaya, and her colleague, Professor Andrew Hooper, from the University of Leeds tell presenter Victoria about these new technological advancements, and ask the crucial question: are we entering a new millennium of volcanic activity in Iceland?

    When looking at clear ocean water, you might assume that, aside from fish and some algae, there isn’t much living in it. But Prof Carlos Duarte knows it is full of life. In fact, his new study shows just how many different microbes – bacteria, viruses & fungi – live in all parts of our ocean. He and his team at King Abdullah University of Science and Technology in Saudi Arabia have created the largest ocean genome catalogue to date. Prof Mark Blaxter from the Wellcome Sanger Institute joins us to discuss this new study, the benefits of hypothesis-free science, and why he believes cataloguing the code of life of all the species on earth is an important endeavour.

    And, lastly, an old dinosaur fossil in New Mexico has been re-examined. What was believed to be of the infamous Tyrannosaurus rex may have been a different species all along. But not all palaeontologists agree. How do scientists even tell a dinosaur species from a fossil? Prof Stephen Brusatte tells Vic that it’s all about comparing bones.
