Episode 306 It’s been discovered that the moon is probably home to $1 trillion worth of platinum. Researchers suggest nearly 6500 of the Moon’s craters were made by asteroids containing commercial quantities of platinum, palladium, rhodium, ruthenium, iridium and osmium. Does that mean space companies are going to head out on mining missions imminently…and should they? Hear the reasons for and against mining on the Moon. When you imagine something in your mind, how does your brain know that it’s not real? Certain brain regions have been identified in a new experiment which help keep reality and make-believe separate. This finding could tell us a lot about conditions like schizophrenia - or what’s going on when we dream. It may even answer that question; are we living in a simulation? Read our imagination special here: https://www.newscientist.com/issue/3545/ A newly discovered emergent behaviour has been found in nematode worms - the world’s commonest animal. These millimetre long worms are able to merge to form superorganisms, creating tentacles or towers that can straddle long distances. Learn about this collective behaviour and how it's coordinated.

The real threat of AI - ethics, exploitation and the erosion of truth 34:43

Episode 305 As artificial intelligence grows into more and more aspects of our lives, it seems we’re just at the beginning of the boom. Hundreds of billions of dollars are being pumped into advancing AI capabilities, making it the best funded area in science. But, just like the dot-com revolution, is it a bubble waiting to burst? In this special episode of the podcast, we explore the growing promise of AI - and also the existential threat it poses. Despite the amount of money going into AI, chatbots are still making glaring mistakes, plagued with hallucinations. All the while students are relying on them to do their homework for them, and others are using them to replace very human tasks, like writing wedding speeches. So we hear from two authors who have been thinking hard about AI and machine learning - and what that means for the future. We also get into the idea of AGI, artificial general intelligence - and its cousin, artificial superintelligence, which may already exist in certain areas. With many researchers concerned about AI overthrowing humanity, is it even worth worrying about? We dig into whether AGI is even possible and who would want to develop it. This discussion has to include some mention of the human and environmental costs of these technologies, too. Energy demands are expected to skyrocket over the next few years - can the planet keep up with the demand? And alongside that, there’s a lot of human exploitation going on to help fuel these machines - a little-known fact that has to be tackled. Finally, is superintelligent AI a threat to the existence of humankind - will they want to wipe us out when they get smart enough? Or is the threat more insidious, one where we watch the slow erosion of truth and democracy?

Are smartphones really causing mental illness in teens?; More evidence of alien life; Digital oak trees 23:24

17 днів тому23:24

23:24

Episode 304 It seems the world is on heightened alert about the impact smartphones are having on our children’s brains. But are we right to be worried? Jonathan Haidt’s book the Anxious Generation has played a big role in this debate, with many researchers agreeing smartphones cause harm and action needs to be taken. But is there actually any scientific evidence to back all of these claims up? The “strongest evidence” for alien life was announced just a few weeks ago - but not everyone was happy with this discovery and it came under quite a lot of fire. The team that discovered this alien signal were analysing data from the James Webb Space Telescope. Now other researchers have looked at the same data and have come to different conclusions. But rather than proving critics right, it seems the evidence for aliens just got stronger. A digital oak tree is on display at Kew Gardens in London. Of the Oak is an immersive installation by art collective Marshmallow Laser Feast in collaboration with ecologists, biologists and researchers. The aim is to show the inner workings of the oak, to allow people to connect more deeply with it and to tune into “tree time”. Chapters: (00:32) Are smartphones causing mental illness in teens?

China’s carbon emissions fall; norovirus vaccine; chaotic breakup of the solar system 27:55

Episode 303 China is becoming a de facto leader in the fight against climate change. Right now it’s the world’s biggest emitter of carbon dioxide, but after years of keeping its emissions steady, they have finally begun to fall. And this is all while China’s power demands have increased - suggesting its efforts to build clean energy are paying off. But is this enough to make a realistic dent on curbing global warming? And how will the uncertainty of President Trump’s administration impact this trend? A vaccine for the dreaded norovirus is in the works - and it’s already proving effective. Known as the winter vomiting bug, this nasty gastrointestinal illness affects 685 million people a year. Thanks to a company in San Francisco and some heroic people who served as test subjects, we may be closer than ever to staving it off. At some point, in a few billion years, our solar system may break up in the most spectacular fashion, simply because of random chaos and instability. But now researchers have found a bigger threat to the survival of our solar system - passing stars. Less random and chaotic, stars actually pass by our sun fairly regularly, and could dislodge planets like Pluto, flinging them out of orbit and impacting the other planets. Do you find yourself teary eyed when cutting onions? Well, you’re in luck. Scientists have found the perfect way to cut an onion without crying. We provide a live demonstration for your amusement.

Ocean wonders and the new arguments against deep-sea mining; biophotons emitted from living things; drumming chimps and the origin of religion 28:02

28:02

We dive into the mysterious world of the deep sea, sparked by a recent executive order aiming to ramp up offshore mineral extraction, as well as new research revealing that 99.999 per cent of the seabed remains unexplored. Experts discuss the surprising lack of deep-sea exploration, the ecological wonders already discovered, like hydrothermal vents and bizarre deep-sea creatures, and the debate over mining nodules from the ocean floor. With new battery tech on the horizon and mounting environmental concerns, questions grow about whether deep-sea mining is driven by necessity or a disregard for the ecosystems we barely understand. Researchers have captured the faint glow emitted by living things to explore what happens when life ends. First theorised a century ago by Russian physicist Alexander Gurwitsch, biophotons are ultraweak light emissions which appear to track metabolism and fade dramatically at death. Could this eerie glow one day help detect disease, or even confirm the moment of death? Chimpanzees across Africa have been observed rhythmically drumming on trees, but what are they trying to say? A new study spanning 11 chimp communities reveals that these drum beats may be individual signatures, offering fresh insight into the roots of musicality and communication. The team discuss how chimps may even show signs of awe or ritual, with their unique responses to storms, fire, and waterfalls. Could drumming mark not just the evolution of rhythm, but the first flickers of spiritual thought?

Is our understanding of light completely wrong? Two consciousness theories go head-to-head; decoding dolphin whistles 28:45

5 weeks тому28:45

28:45

Episode 301 Our understanding of the nature of light might be completely wrong. The double-slit experiment is one of the most famous experiments in physics and is how we’ve understood light for over 200 years. But a team is now suggesting we’ve got the interpretation all wrong - that light is in fact not a wave and is only made up of particles. If true, this is major. The authors of this study were left scrambling as “all hell broke loose” when they made the discovery. And the best part? Dark photons may be involved. A 7 year study into the nature of consciousness has reached its conclusion - pitting two major theories against one another. Integrated information theory suggests levels of consciousness exist in any system, including rocks and fetuses. Global neuronal workspace theory claims specific brain regions are responsible for consciousness. After 256 brain scans - are we any closer to an answer? A decades-long study involving 170 wild dolphins has allowed biologists to decode their whistles. Hear dolphins recorded in the waters of Sarasota, Florida, which show how the animals communicate in various ways - and even give themselves names.

Weekly: Why the climate crisis is an issue of injustice and inequality 41:50

6 weeks тому41:50

41:50

Episode 299 In a climate justice special episode of the podcast, the biggest issue of the century is up for discussion. Find out the true impact of climate change on our planet and who should be paying to fix the crisis. Rowan Hooper and Madeleine Cuff are joined by two climate experts - Friederike Otto and Joyce Kimutai from the World Weather Attribution project at Imperial College London. This episode is dedicated to answering three questions - starting with the issue of climate attribution. To what extent can we blame climate change for extreme weather events like hurricanes, droughts, heatwaves, floods and wildfires? Find out how climate attribution began as a fringe science and how it has evolved to become a firm part of public consciousness. The next question is one of climate justice - how can we make sure rich countries pay for the loss and damage caused to poorer countries by climate change? The argument is that poorer nations are least responsible for climate change, yet they are most affected by its impacts. So at the latest UN climate summit, COP28, a lot of money was pledged - yet hardly any of it has actually materialised. So what’s going on? And the third question is about litigation - can climate attribution be used to achieve justice, by forcing climate polluters to pay up? A trial is ongoing where a company in Germany is being sued for its role in damaging the climate - but it’s still unclear whether the case will be successful. The hope is with climate attribution, it’ll be easier to bring cases like this forward and offer up a more detailed picture of how much damage has been done - and how much money is owed.

Episode 300 The first genetically engineered synapses have been implanted in a mammal’s brain. Chemical brain signals have been bypassed in the brains of mice and replaced with electrical signals, changing their behaviour in incredible ways. Not only did they become more sociable, they were also less anxious and exhibited fewer OCD-like symptoms. This work has sparked hope that one day we could use this technology to help humans with mental health conditions. But would you want someone making permanent edits to your brain? For the first time, climate scientists can now link specific fossil fuel companies to climate-related economic damages in particular places. A new method has been developed that can show the exact impact these companies are having on our environment - which the world’s top five emitters linked to trillions of dollars of economic losses. Find out how scientists have managed to piece this together - and whether these companies are about to face massive lawsuits. As we reflect on the death of Pope Francis, we explore his legacy on scientific issues and his transformative stance on climate change. As the spiritual leader of 1.4 billion Catholics, he became an influential figure in advocating for better care to be taken of our planet. Will his legacy continue with the next Pope?

Episode 298 Big news has just broken - astronomers claim they’ve detected the strongest evidence for alien life yet. The news has got the world’s media fired up with excitement - but is this really a “revolutionary moment”? Astronomers studying the atmosphere of a distant planet called K2-18b say they have detected a molecule called DMS that is only produced on Earth by living organisms, so it’s thought life might be producing it there too. Hear from the lead researcher on this project, Nikku Madhusudhan of the University of Cambridge, who says “these are the first hints of an alien world that is possibly inhabited”. But even if this biosignature detection is confirmed, would it be the slam dunk everyone thinks it is? In this episode, Alex Wilkins and Rowan Hooper offer a bit of balance to the discussion and explore how far this is from definitive evidence of alien life. We also hear the views of Laura Kreidberg, managing director of the Max Planck Institute for Astronomy.

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.

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.

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.

Episode 294 Markings discovered on rocks from Mars look to be good evidence that microbial life once existed on the Red Planet. NASA’s Perseverance rover spotted little speckles on rocks in part of Jezero crater, and minerals usually formed in the presence of water. New analysis suggests these markings also contain signs of organic compounds. Presented with the possibility of microbial Martians, can we now say Mars really did once have life? Dark energy, the mysterious force thought to be driving the expansion of the universe, might be getting weaker. If it is, that completely upends our understanding of the universe - from one that’s getting bigger and bigger, to one that could eventually collapse in a “big crunch”. Results from the Dark Energy Spectroscopic Instrument (DESI) in Arizona may be the biggest discovery about dark energy we’ve had in 25 years. Last year we had the controversial discovery that “dark” oxygen may be produced by metallic nodules on the seafloor. But it was widely contested and the exact mechanism unknown. But researchers in China now think they’ve figured out what’s going on - dark oxygen could be key to keeping deep sea creatures alive, with implications for life beyond Earth.

Episode 293 The future of NASA and of US science is under threat, following cuts made by the Trump administration. Johns Hopkins University lost $800 million in grants this week which will impact the health of people all over the world. At the same time, there’s chaos at NASA where the budget is set to be cut in half, with multiple people losing their jobs overnight. What missions will we have to sacrifice - and will NASA survive? As we pump ever increasing amounts of carbon dioxide into the atmosphere, some people argue this is actually a benefit to the world’s plant life. As carbon dioxide rises, photosynthesis can increase - but only up to a point. New research shows there’s a limit to this effect and many, many consequences. One study on trees suggests rising CO2 levels could impact the carbon storage capacity, and the lifespan, of the world’s forests. Our understanding of memory has been flipped on its head. Researchers have been looking into a memory illusion that warps our perception of time. In a clever experiment, they’ve shown that experiencing something multiple times not only makes our memory of it stronger, but also makes us think it’s an older memory too.
