    Weekly: Dire wolves (not) brought back from extinction; US science in existential crisis; how to pour the perfect coffee
    Apr 11 2025
    Episode 297 The “de-extinction company” Colossal Biosciences claims to have brought dire wolves back from extinction. This is an ancient animal that roamed Earth 10,000 years ago and famously is depicted in Game of Thrones. After gene editing grey wolves, three pups have been born. But is it right to call them dire wolves, or are these just grey wolves in dire wolf clothing? It’s a turbulent time for US science, with massive and sweeping cuts being made to jobs and budgets. Departments like the National Institutes of Health and the Food and Drug Administration have been affected – raising major concerns about the future of public health in the country and beyond. Physicists have discovered the perfect way to pour a cup of coffee. Hot on the heels of the perfect cacio e pepe recipe and how to make the perfect boiled egg, this discovery is yet another hilarious hack that works in principle but is a massive faff. Chapters: (00:31) Return of the dire wolf (08:58) Turbulent time for US science (16:36) Perfect way to brew a cuppa coffee Hosted by Penny Sarchet and Timothy Revell, with guests Michael Le Page and Chelsea Whyte.

  • Weekly: How plant skin transplants could supercharge crops; China’s pollution win spikes global temperatures; the oldest ivory tools ever found

    Weekly: How plant skin transplants could supercharge crops; China’s pollution win spikes global temperatures; the oldest ivory tools ever found
    Apr 4 2025
    Episode 296 There’s a strange phenomenon in the plant world that we’ve known about for ages - but have only just figured out how to make use of it. Thanks to a process that sometimes happens during plant grafting, we can give plants skin transplants. This process produces ‘graft chimeras’, which have been seen as mere curiosities for many years. But now one company in the Netherlands is now planning to do something more with them, creating a whole new world of plant combinations that could produce more pest resistant crops or more delicious fruits. Air pollution in China has been a hot topic for many years, especially since the 2008 Beijing Olympics. But China has been successful in bringing emissions from aerosols down drastically - a massive win for the health of people in the country. However, there’s been an unintended consequence, as their efforts to clean the air have caused a spike in the rate of global warming. What’s going on? Find out how this all links to the subject of geoengineering. The oldest ivory tools ever found have been discovered in Ukraine. Thought to be created by our ancient ancestor, Homo heidelbergensis, these tools made from mammoth tusks are 400,000 years old. They give a surprising window into the lives of ancient humans - who may have been more intelligent than we realised. Chapters: (00:31) Giving plants skin transplants (07:16) How China’s pollution win has spiked global temperatures (16:34) The oldest ivory tools ever found Hosted by Rowan Hooper and Penny Sarchet, with guests Michael Le Page, Madeleine Cuff, Jeroen Stuurman and Vadim Stepanchuk.

    Weekly: A remarkable view of pregnancy; how to waste less time on your smartphone; superacid diamond rain
    Mar 28 2025
    Episode 295 The changes the body goes through during and after pregnancy have been examined in more detail than ever before. A landmark study is finally helping us to piece together some of the mysteries and myths surrounding this time – from how long it takes the body to go back to “normal” after birth to the extended periods of nutrient deficiency. This comes after a flurry of studies have given us the clearest picture yet of how the brain changes – and is dramatically remodelled – throughout pregnancy. Are you worried about your smartphone habit? Science is upending our understanding of phone use and just how damaging the urge to doom-scroll can be. Are smartphones really killing our sleep and distracting us more than ever? And is it really impacting the mental health of children? The answers are not what many people assume. One of the weirdest substances in our universe is one we very much take for granted – water. Not only does it perform impressive feats that we see every day, but water can also transform into a superacid, potentially resulting in diamond rain falling on planets in our solar system. Find out how it could be doing this somewhere in the cosmos right now. Chapters: (00:28) The effects of pregnancy (07:16) How bad is smartphone use? (16:34) Surprising facts about water Hosted by Penny Sarchet and Timothy Revell, with guests Carissa Wong and Alexandra Thompson.
