DeepMind Is Simulating Entire Worlds - Ready for AI Robots

Episode 374 Google DeepMind is simulating entire worlds using AI - that can be interacted with in real time. “World models” simulate the environment and physics of the real world. And DeepMind’s Genie 3 model allows people to create these worlds with basic image and text prompts. The idea is not just to allow people to explore these worlds, but to serve as a testbed for AI agents to learn how to interact with the world before they are deployed in humanoid robotic bodies. Could this be the next big step towards artificial general intelligence (AGI)? Joshua Howgego speaks to Jack Parker Holder, Research Director at Google DeepMind, about the latest developments.

Ötzi the Ice Man Contains Still-Living Microbes

Episode 373 Despite being 5,300-years-old, the gut microbiome of the famous Ötzi the Ice Man appears to be still alive. A mix of ancient and modern bacteria have been found on Ötzi’s mummified remains - which are preserved in icy conditions. Found in 1991 by hikers on a glacier in the Alps, Ötzi has already taught us an incredible amount about the life of humans living in Europe during the Copper Age - and continues to reveal his secrets. While we unpack this surprising news, we also explore some of the other fascinating discoveries Ötzi has led us to over the years, from the type of food ancient people ate during this period, to the different animal skins they wore as clothing. We also discuss the six tools he was found with - and why he was covered in 61 tattoos. To discuss the new finding, Rowan Hooper and Penny Sarchet are joined by New Scientist’s Sam Wong.

The Thwaites 'Doomsday' glacier's ice shelf is about to break away

Episode 372 Part of the world’s widest glacier is about to collapse – one of the dramatic changes underway that could ultimately trigger a 3 metre rise in sea levels, threatening coastal cities around the world. Thwaites is a massive glacier in Antarctica – the size of Florida. A key part of the glacier could break away any day now -– an ice shelf that helps protect the main glacier from warm ocean water. Scientists are shocked by the speed at which these changes have happened. Is there anything we can do to stop it? To discuss the news, Rowan Hooper and Penny Sarchet are joined by New Scientist’s Alison George – former British Antarctic Survey scientist.

Science Reveals Neanderthals Had Dentists 60,000 Years Ago

Episode 369 A strange tooth found in a Siberian cave has pushed back the earliest evidence of dentistry by 45,000 years. The weird thing is, the evidence comes from a Neanderthal tooth - upending what we thought these ancient humans were capable of. Markings on the 60,000-year-old molar show Neanderthals may have used stone tools to “drill” the tooth to treat dental decay. A team of scientists has recreated the experience - and it sounds gruesome. And that’s not all for Neanderthal news - as archaeologists have discovered an ancient kneeprint made in clay around 175,000 years ago. It was found in a cave containing a mysterious stalagmite circle that may have been deliberately constructed. Could this suggest Neanderthals were engaging in some sort of religious practice? Rowan Hooper and Penny Sarchet are joined by New Scientist’s Sam Wong and Michael le Page to discuss these two discoveries Listen to Change Your Mind, the new podcast from New Scientist: https://podfollow.com/1896636265 To read more about these stories, visit https://www.newscientist.com/ Learn more about your ad choices.

Some Scientists Want To Resurrect Extinct Species – Is It Even Possible?

Episode 371 The moa was a giant flightless bird from New Zealand that died out around 500 years ago. Are we about to see it brought back from extinction? Colossal Biosciences say they have made an artificial egg shell that is a step towards recreating the massive eggs of moas (and dodos). This is huge news… if it works. Is this really enough to bring them back to life - and should we even be trying? We discuss the news and wider ethical implications of de-extinction - including Colossal’s headline goal of bringing back the woolly mammoth to assist in the climate crisis. Rowan Hooper is joined by New Scientist’s Michael Le Page and palaeontologist Victoria Herridge.

A “Super El Niño” Is Coming - And It Could Trigger Global Climate Chaos

Episode 361 The Earth is about to enter an extremely strong climate phase that could cause major disruption on a planet-wide scale. This “super El Niño” - or “Godzilla El Niño” - threatens to make 2027 the hottest year on record. If it’s as strong as scientists fear, the weather event will bring droughts to some areas of the world and floods to others, causing food shortages and billions of pounds of damage. And with the world already warming faster due to human activity, the effects will only be intensified. To discuss what we can expect from the near future, Rowan Hooper and Penny Sarchet are joined by New Scientist climate reporter Alec Luhn.

Food shock is inevitable due to the Iran war – and it could get bad

Episode 357 A global food shock is on the way because of the ongoing war in Iran. Your food bill is expected to rise significantly. The conflict is showing just how fragile our food system is, as spikes in fuel, fertiliser and pesticide prices begin to have knock-on effects around the world. With food availability in jeopardy, should we be stocking supplies at home? Coupled with the worsening climate and environment crises - and governments increasingly incentivising the production of biofuel - there could be tough times ahead. So how can we prepare? From eating less meat and raising less livestock, to countries focusing on renewable energy and becoming more self-sufficient - will this shock finally be what’s needed to force leaders to take action? To discuss this critical issue, Rowan Hooper is joined by climate, energy, and food systems professor Paul Behrens - and New Scientist reporter Michael Le Page.

Genetic analysis reveals how the Neanderthals went extinct

Episode 359 DNA analysis of 10 Neanderthal people is shedding light on why their populations declined 75,000 years ago - eventually leading to their extinction. After being hit by a cold spell, we can see Neanderthals lost a lot of genetic diversity as their numbers dwindled. Living in small, isolated groups, we see evidence in both genetic and archaeological evidence that this pushed the human species to die out. One exception to this trend is Thorin - known as the last Neanderthal. We explore why his tribe may have been able to cling onto existence for longer than the rest of their species. It wasn’t long ago this kind of understanding about ancient human species was well out of reach. Now the field is moving forward rapidly. What will we find next? To discuss this new finding - and to look at the genetic history of interbreeding between humans and Neanderthals - Rowan Hooper and Penny Sarchet are joined by Alison George and Michael Marshall.

The Hidden Methane Time Bomb That Could Accelerate The Climate Crisis

Episode 370 The melting ice caps are accelerating global warming and contributing to sea level rise, but could also contribute to a different kind of climate catastrophe. The melting may cause massive amounts of frozen methane to bubble up into the atmosphere. It happened thousands of years ago - and scientists are concerned it’s about to happen again. Methane is a greenhouse gas which is 86 times more potent than CO2. Some estimates suggest this frozen methane - methane hydrates - contain twice as much warming potential as all the coal, oil and gas on Earth. Scientists have now discovered a new way for methane in Greenland to be unleashed. It’s not a threat that has been taken seriously as the evidence has been inconclusive. But perhaps it’s time for us to take notice? Rowan Hooper and Penny Sarchet are joined by New Scientist’s Alec Luhn to discuss the news.

Record Heat, Wildfires and Drought - The Climate Crisis Is About To Accelerate

Episode 364 Global temperatures are rising faster than ever - and with a strong El Niño on the way, scientists are warning we could temporarily breach 2°C of warming above pre-industrial levels. While other models suggest it may only hit 1.75°C, either option is bad news for the climate. The European state of the climate report has just been released, painting a picture of a rapidly warming world. Temperatures in Europe are rising faster than any other continent - and places like Iceland, Norway and the UK have all experienced record breaking years. As we’re already watching the impacts of this heat on biodiversity, wildfires, harvests and more - can we handle a 2°C rise in temperatures? And does this signal the end of the Paris goal to limit warming to 1.5°C? Despite the gloom, there is one glimmer of hope. One species of warm water corals seems to have adapted to these extreme surges in heat - and is surviving against the odds. Rowan Hooper and Penny Sarchet are joined by New Scientist reporters Alec Luhn and James Woodford.
