The World, the Universe and Us

There’s no moon like our moon. A celestial body twinned with Earth, the moon guides the tides, stabilises our climate, leads the rhythms of animal behaviour and has long been a source of wonder and awe.  Our Moon: How Earth's Celestial Companion Transformed the Planet, Guided Evolution, and Made Us Who We Are, is a new book from science journalist Rebecca Boyle. In it she takes an intimate look at...

#240 A major step has been made toward bringing woolly mammoths back from extinction – sort of. The company Colossal has the ambitious goal of bringing its first baby mammoth into the world by 2028. And its newest advance, announced this week, is in turning adult Asian elephant cells into stem cells. But it’s still a long way from here to the company’s vision of cold-adapted elephants fighting cli...

This is a re-airing of a podcast originally released in February 2021. Keeping you cosy this week is an episode all about warmth - emotional, physiological and geological. We have an unexpected start to the show, with bees taking the spotlight, but it turns out these cold-blooded little insects can generate immense warmth when necessary. The team then takes a much bigger view of warmth, discussing...

#239 Two decades ago, following the Human Genome Project’s release of a first draft in 2001, genetic testing was set to revolutionise healthcare. “Personalised medicine” would give us better treatments for serious conditions, clear pictures of our risks and individualised healthcare recommendations. But despite all the genetic tests available, that healthcare revolution has not exactly come to fru...

Freezing temperatures, dust storms, radiation, marsquakes – living on Mars right now would be hellish. And getting there remains a multi-year journey. But what if we could make it habitable? Could we one day build settlements on the Red Planet or send human scientists to search for life? That’s the premise of the TV series For All Mankind, which explores a future where the space race continued aft...

#238 ADHD is a condition that affects millions of people and is marked by impulsivity, restlessness and attention difficulties. But how did ADHD evolve in humans and why did it stick around? Through the help of a video game, a study shows that these traits might be beneficial when foraging for food.  In 2023, we hit record after record when it comes to high temperatures on Earth, including in the...

This is a re-airing of a podcast originally released in February 2021. Prepare to feel relaxed, tingly and amazed all in the space of 20 minutes. This episode is all about sound. We start with the musical tones of an elephant trumpeting, followed by a recording from Cornell University’s Elephant Listening Project, showing how they communicate at an infrasonic frequency, which humans can’t ordinari...

#237 Glaucoma, which can cause blindness by damaging the optic nerve, may be reversible. Researchers have managed to coax new optic nerve cells to grow in mice, partly restoring sight in some. How the treatment works through an eyeball injection and why, for humans, prevention and early detection are still the best options. Black holes, just like planets and stars, spin. But they may be spinning a...

Real tech billionaires are reportedly building secret bunkers in case of post-apocalyptic societal collapse. It’s a frightening prospect, a world where only the super rich survive catastrophe. But it’s a world one author is exploring in her latest novel. Naomi Alderman is the prize-winning and best-selling author of The Power. Her latest book The Future imagines a world where billionaires survive...

#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 r...

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...

#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.   El...

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 th...

#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 – appare...

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 so...

#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...

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 fin...

#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 rainfore...

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, incl...

#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...

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...

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...

#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 wi...

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 environ...
