Episode 283
On this special episode of the podcast, we set you up for the year ahead. 2025 has been declared the year of humanoid robots. Futuristic robots that look like us are already being rolled out by companies like BMW and Tesla - and production is set to ramp up. One company is even planning to create an army of 10,000 warehouse robots called Digit.
We’re going to see big changes in the food industry too, as the US is set to approve CRISPR gene editing for pigs. The idea is to create elite livestock that are less prone to illness and can feed more people. Bananas are having their genes edited too, so they can fight off a major fungal disease that’s spreading around the world. And new types of butter, chocolate and ice cream are being made without the help of agriculture, just microbes.
Ozempic is showing surprising promise in the fight against Alzheimer’s. Based on a growing body of evidence, two big trials are looking into this unlikely connection and are set to conclude in 2025. If the results are positive, this could be a real breakthrough for the treatment of the disease.
Geoengineering is picking up, with more research and financing going towards plans to artificially cool the planet. Many methods are being explored, but one major area of interest this year is solar geoengineering, with the world’s largest conference on the subject set to take place in South Africa in May.
COP30 arrives this year and after the blowout that was COP29, tensions are high and motivation is low. With the US set to pull out of the Paris Agreement, will we be able to move forward on climate action, or will we be dragged backwards?
And it’s been more than 20 years since the last flight of Concorde, a supersonic commercial plane which failed for multiple reasons - one of those being just how loud it was. Now, in 2025, NASA is trying to fix that problem by creating a quiet supersonic plane, with other companies following suit. Will we go supersonic again this year?

Weekly: The Best of New Scientist in 2024: From Volcanic Diamonds to Immortal Brains
Episode 282
Looking back at some of the best stories New Scientist has published in 2024, this episode is a treasure trove of knowledge that will serve you well over the holiday season. Rowan Hooper hosts a panel of New Scientist journalists, as they take it in turn to highlight their favourite moments from the year.
Head of features Josh Howgego kicks off by looking at the race to find an amazing and strange form of hydrogen, known as ‘gold hydrogen’ - a game-changer for sustainability which may be more abundant than we first realised. He also discusses the mystery of kimberlites, supersonic volcanoes that spew diamonds which went extinct millions of years ago.
Alison George takes on the story of Thorin the neanderthal, whose remains are shedding light on how the ancient species died out - and surprisingly, it may not have been our fault. She also explores the new science of tinnitus and how it might help us cure hearing loss one day.
Thomas Lewton looks at some mad physics stories from the year, including an unnerving idea that a quantum fluctuation involving the Higgs boson could cause the universe to vanish at any moment. They also explore an old theory that quantum effects explain consciousness, which has been revived thanks to new research into anaesthetics and brain organoids.
And Linda Rodriguez-McRobbie throws some nuance into the discussion about screen-time, something often blamed for the current youth mental health crisis - and why it might not be all bad. She also explains how researchers this year were able to reanimate a pig’s brain, four hours after it was separated from its body, upending our concept of death.

Weekly: Most Amazing Science Stories of 2024 | Live at the Science Museum
Episode 281
In this special episode recorded live at the Science Museum in London, we celebrate some of the best, most awe-inspiring science stories of 2024.
Round one kicks off with the panelist’s stories of the year, including the discovery that thousand-year-old preserved brains are much easier to find than we realised, that metallic nodules found on the sea floor could be acting as “geobatteries”, creating oxygen in the deep sea, plus a surprising finding involving Dyson Spheres that may hint at the existence of advanced alien life.
In round two the panelists discuss their cultural highlights of the year. On the line up is an installation in London called ‘Breathing with the Forest’, a time-travel novel called ‘The Other Valley’, the stage show reimagining of ‘Dr Stangelove’ and an absurdist comedy about climate diplomacy called ‘Rumours’.
Round three is a quiz for the audience asking questions like, do warm drinks taste more alcoholic than cold ones? What animal can be added to milk to initiate the yoghurt-making fermentation process? And which animal can survive with almost no sleep?
And round four celebrates stories that will make you say “Wow!”, plus a moment of good cheer. These include flowers that can sequester nickel and be turned into metal, how brains and other body parts can be brought back from the dead, the discovery of the world’s largest coral reef and the invention of a hospital for fungal-infected frogs.
On the panel are Rowan Hooper, Catherine de Lange, Sam Wong and Madeleine Cuff.

Weekly: Does Google’s new quantum computer prove the multiverse exists?; 8 ways to keep your brain young
Episode 280
Google claims it has pulled ahead in the race for quantum supremacy. Its new Willow chip has completed a task in 5 minutes that a classical computer would take 10 septillion years to complete. But the biggest breakthrough is how it excels in error correction. Find out what this means and why some scientists believe this new quantum computer proves the existence of the multiverse.
Data from one of the world’s largest collections of brain scans is shedding new light on how to keep our brains young. Analysing scans from the UK Biobank project, scientists have identified 13 proteins that are responsible for how quickly or slowly your brain ages. But research on how to target these proteins is still ongoing. For now, the team reveals 8 science-backed ways you can keep your brain young and boost longevity right now.

Weekly: Antarctica special, brain implant made from living cells, best TV and film of 2024
Episode 279
Antarctic sea ice is melting at an unprecedented rate. A collapse like the one we’re seeing was given just a 1 in 700 billion year chance of happening, based on climate models - we basically thought it was impossible. Melting ice in Antarctica will have global scale, knock-on ecological and climate consequences. To address the crisis, five hundred researchers met in Australia for an emergency summit for the future of the Antarctic. Sarah Thompson, one of the scientists at the conference, is working in Antarctica right now and shares her experiences assessing the damage in the region. Also hear from Sharon Robinson from the University of Wollongong, who explores how the ecology of the region is changing.
A new type of brain implant technology is being developed that will allow direct access to a patient’s brain in a more intimate way. Most devices place metal electrodes and wires into the brain, but this method is instead using living neurons to form a connection with the brain. Brain-computer interfaces are used to help treat conditions like ALS or stroke, as well as allowing patients to control technology with their mind. Researchers at the Science Corporation in California have tested their new method on mice - but can it be done in humans?
If you’re looking for a great science-based TV series or film to get stuck into this December, our resident TV critic Bethan Ackerley is here with all the highlights of 2024. She discusses everything from the unconventional superhero show ‘Supacell’, to the fabulous ‘3 Body Problem’ and the latest ‘Planet of the Apes’ film. Read Beth’s complete TV and film review here:
