#236 This week marks two major milestones in the world of fusion. In 2022 a fusion experiment at the Lawrence Livermore National Laboratory created more power than was required to sustain it – now, the same team has improved this record by 25 per cent, releasing almost twice the energy that was put in. Meanwhile, the UK’s JET reactor set a new world record for total energy output from any fusion reaction, just before it shut down for good late last year. Why these two milestones inch us...

This is a re-airing of a podcast originally released in February 2021. From some of the lightest creatures on earth, to the heaviest things in the cosmos, this episode is all about mass. It’s a magical opening to the show as the team discusses a group of insects called fairy wasps which are so light it’s near impossible to weigh them. They then turn to matters of massive proportions, discussing a little thing called dark matter. Finally the team wraps up by looking at the surprising, and...

#235 In very rare cases, Alzheimer’s disease could be transmitted from person to person during medical procedures. This finding comes as five people have developed the disease after receiving contaminated human growth hormone injections in the late 1950s to early 1980s – a practice that is now banned. What this finding means for medical settings and why most people don’t need to be concerned.   Elon Musk’s mind-reading brain implant company Neuralink is carrying out its first human trial. The...

Very few places on our planet appear untouchedby humans, but in those that do, nature is still very much in charge – and the scenery is breathtaking. In the new BBC series Wilderness with Simon Reeve, journalist Simone Reeve takes us into the heart of Earth's last great wild areas, including the Congo Basin rainforest, Patagonia, the Coral Triangle and the Kalahari desert in Southern Africa. In this episode of CultureLab, TV columnist Bethan Ackerley asks Simon about the series and his many...

#234 Is AI really ready to take our jobs? A team looked at whether AI image recognition could replace tasks like checking price tags on items or looking at the pupils of patients in surgery.  The researchers found only a small fraction of these vision-reliant tasks could be cost-effectively taken over by AI – for now, anyway. There’s an old myth that singing to your plants helps them grow – apparently this actually works with fungus. A pair of experiments has found that fungus grows much more...

This is a re-airing of a podcast originally released in February 2021. This episode is all about music, so today’s journey of escapism comes complete with odd, relaxing, soothing and interesting sounds to guide you through. The team opens with the sounds of animals, specifically the singing - if you can call it that - of gorillas, and the jazzy birdsong of the thrush. They then treat you to the sounds of data sonification, courtesy of Milton Mermikides, who translates motion into music, like...

#233 A cloned rhesus monkey named ReTro is said to be in good health more than three years after his birth – a landmark achievement, as no other rhesus clone has lived to adulthood.. However, the method used to clone ReTro used fetal cells, a method that cannot create identical clones of adult primates. The method could still be useful for medical research.  Fermented foods are meant to be healthy and good for our guts, but there’s a problem. Researchers have found antibiotic resistant...

NASA astronaut Christina Koch not only took part in the first ever all-female spacewalks, but she also holds the record for the longest single spaceflight by a woman, after spending 328 days on board the International Space Station. So what does it take to live in space for such a long time, what does it mean to be a record-breaking astronaut – and how do you get used to gravity again when you finally come back home? New Scientist space reporter Leah Crane asks Chrstina all of these questions...

#232 During pregnancy the brain undergoes profound changes – almost every part of the cortex thins out and loses volume by the third trimester. It’s such a big change that you can tell if someone’s pregnant just by looking at a scan of their brain. How researchers discovered these changes and why they might be occurring. A massive, ancient group of cities has been discovered in the Amazon rainforest using lasers. It’s the biggest pre-Columbian urban area ever found in the Amazon and parts of...

This is a re-airing of a podcast originally released in January 2021. The theme of this episode is alliances - human, biological and atomic. We start by celebrating the amazing properties of lichen, the symbiotic relationships it forms, how it shaped the earth and simply how beautiful it is to look at. Then we explore how carbon is able to create such an incredibly diverse range of materials, including soot, diamonds and graphite. We wrap up by delving into the life of renowned Hungarian...

#231 It’s a new year and that means new science. But what (that we know so far) does 2024 hold?  On the space front, agencies around the world have as many as 13 missions to Earth’s moon, while Japan’s MMX mission will launch to take samples from the Martian moon Phobos. NASA will finally launch the Europa Clipper mission to explore Jupiter’s ocean-bearing moon.  On the technology front, Europe’s first ever exascale supercomputer, capable of performing billions of operations per second – only...

This is a re-airing of a podcast originally released in January 2021. An episode of Escape Pod all about understanding. We start by discussing the self-awareness of dolphins and whales, and the intricacies of their language and vocalisations. Then we marvel at the seemingly impossible abilities of gymnasts and ballerinas, most notably Simone Biles who performed a legendary triple double. And then we take a look at the Chinese board game Go - a game with more possible moves than there are...

What was your favorite science story of 2023? Was it the rise of orca-involved boat sinkings? Or maybe the successful landing of India’s Chandrayaan-3 mission at the moon’s south pole?  This week, it’s the second and final part of our annual event about the best science stories of the year, with a roundup of some of the good news, animal news and all-around most important stories of 2023. Like how researchers discovered the high-tech material called graphene can also occur naturally…and did,...

Are you looking forward to catching up on some reading over the holiday season? Or perhaps you are on the prowl for book recommendations after receiving a few literary gift cards? If so, you are in luck – this episode is all about the books we think you’ll love to read. In this episode of CultureLab, culture and comment editor Alison Flood appears in her role as professional bookworm to share some of her favorite reads of the year. From a sobering story of life in the human-polluted ocean...

#229 Your hands are heavier than you think. Beer goggles aren’t real. And many water utilities in the United Kingdom still use dowsing to find leaks in pipes.  It’s the first part of our annual best-in-show of science stories from the year, with a roundup of some of the funniest and most futuristic-feeling headlines from 2023. Like the Euclid Space Telescope’s successful start to a mission that will map the sky and offer new insights into dark matter and the very structure of the universe....

Composer Erland Cooper is known for playful, innovative, experimental projects. For example, he buried the only audio copy of a 2021 composition – then left treasure hunt clues for people to try to find it. Which one couple, eventually, did. In this episode of CultureLab, Cooper talks to writer Arwa Haider about his newest album, Folded Landscapes, where he is deep in conversation with the environment and our changing climate. The movements of the piece were recorded with the Scottish...

Cannabis is one of the oldest products of human cultivation. And as it becomes increasingly legal for medical and recreational use around the world, its popularity is growing as well – even as researchers, limited by government prohibitions of the past and present, race to understand how the hundreds of chemicals in pot actually affect us and what the benefits and risks may be. But the object of all this research is itself changing: cannabis consumed today is more than ten times more potent...

#228 We have a new, landmark climate deal, signalling the beginning of the end of fossil fuels. But even as the announcement at COP28 includes commitments for some of the most pressing issues, including giving money to countries most affected by climate change and setting goals for more renewables, some critics aren’t satisfied. With weak language around  “transitioning away from” fossil fuels, does the deal go far enough? The first ever scientific discoveries have been made by an artificial...

The Australian outback is vast and the population is really spread out. This makes getting access to emergency healthcare incredibly challenging, as you may be a thousand kilometres or more from the nearest major hospital. The solution? Australia’s Royal Flying Doctor Service – one of the largest aeromedical organisations in the world, and, at nearly 100 years old, the first of its kind. In this bonus episode of the podcast, Australia reporter Alice Klein speaks to two RFDS team members about...

Human beings have cultivated cannabis for thousands of years. We have been using it for its euphoric effects for at least several thousand. And as prohibition in the United States and other nations gives way to legal, recreational use, more people are picking up pot for help with sleep, pain, or simple relaxation. But as medical and recreational use become more popular and increasingly accessible, what’s actually going on inside your body and brain when you imbibe? Cannabinoids, the chemicals...

#227 Quantum computing researchers at IBM have stepped up the power of their devices by a huge amount. The company’s new device Condor has more than doubled the number of quantum bits of its previous record-breaking machine, which was released just last year. This massive increase in computational power is just one of the company’s latest achievements. It has also announced Heron, a smaller quantum computer but one that’s less error-prone – and therefore more useful – than any IBM has...

Did your chemistry lessons involve baking chocolate lava cakes? Have you ever wanted to eat your biology homework? While ‘Lessons in Chemistry’ brought a fictional cooking-as-chemistry story to TV viewers this fall, real-life scientist Pia Sörensen’s students are some of the few who can actually answer “yes.” Sörensen’s directs Harvard University’s Science and Cooking program, which teaches science lessons through the culinary arts. She is the author and editor of several books, including the...

#226 This year’s COP28 could be the most important climate summit since the Paris Agreement in 2015. After opening in Dubai on Thursday, this will be the first time countries will formally take stock of climate change since agreeing to limit global warming to 1.5 degrees Celsius. While we can expect world leaders to make some major commitments regarding renewable energy, sceptics are concerned the location of the summit will mean that fossil fuel interests end up disproportionately shaping...

Cannabis is having a moment. Half of the US population lives in a state where marijuana is legal, and 9 in 10 people nationwide support legalisation in some form. This is a stark difference from mere decades ago, when prohibition was the norm in the entire US. Meanwhile, if you live in Malta, Uruguay, Canada – and maybe soon, Germany – your entire country is one with legal recreational pot. And access to medical marijuana extends to even more countries, including the UK and Australia. But as...

#225 Life on Mercury? That would be a shocking discovery. The planet is incredibly inhospitable to life… as we know it. But the discovery of salt glaciers on its surface has opened up the possibility that extremophile bacteria could be buried beneath its surface. Lucky then that the BepiColombo mission is planned to take another look at Mercury soon. Ever wondered why you can go all night without getting hungry but can’t last a few hours in the day? Well, there may be cells in our brains that...
