Craig Venter’s Legacy: The Most Influential Geneticist Since Watson and Crick

Episode 365 Craig Venter, one of the world’s most influential geneticists, has died aged 79. He leaves behind an incredible - and complicated - legacy. Venter is primarily known for playing a leading role in the sequencing of the human genome. Later he pioneered the field of synthetic biology, creating what was described as the first synthetic life form - a feat that was not without controversy. So what drove Venter? And why was he so compelled to promote the idea of science as a competitive race? We discuss his many achievements, including his work in marine biology - and explore the pioneering methods behind it all. Rowan Hooper and Penny Sarchet are joined by science writer Mike Marshall, and former New Scientist editor Roger Highfield.

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.

The Wood Wide Web: The Forest Discovery That Sparked a Backlash

Episode 363 Suzanne Simard is a world-renowned forest ecologist who shot to stardom with her first book Finding the Mother Tree. It tells the story of her life’s work, showing trees and plants are connected through fungal networks, demonstrating a kind of wisdom and intelligence. Now, with the release of her latest book When the Forest Breathes, she’s keen to highlight the destructive and extractive forestry practices of the modern age - and why Western science needs an update. Rowan Hooper sits down with Simard under the famous Lucombe Oak in London’s Kew Gardens. Together they explore the concept of the ‘wood wide web’, the name given to her breakthrough work showing communication between forest trees via an underground fungal network. They discuss the scientific backlash that came when she popularised this work and how it all came at a particularly difficult time in her life. And they explore her time spent with indigenous peoples in the Amazon rainforest. As Simard aims to make us view forest ecosystems in a more holistic and regenerative way - what will it take to truly change the industry?To read more stories like this, visit https://www.newscientist.com/ Learn more about your ad choices.

Chernobyl 40 Years On: Legacy of the World’s Worst Nuclear Disaster

Episode 362 It’s been 40 years since the world’s worst nuclear disaster unfolded. Since the explosion at Chernobyl in 1986, the world has feared nuclear power - and the widespread damage it can do. But are we right to fear it? Though it’s left a lasting scar on the region, nuclear power is still safer than fossil fuels - which kill millions of people each year. So what will it take to change public opinion? We examine the lasting impact of nuclear fallout on Chernobyl - and how things have changed in the exclusion zone over four decades. Rowan Hooper is joined by New Scientist reporter Matt Sparkes, who shares news of his recent visit where he met the families who still live there. And Professor Jim Smith, author of Chernobyl: Catastrophe and Consequences, explains how the ecosystem and wildlife are thriving - and how he’s been making Atomik Brandy out of radioactive apples from the region.

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.

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.

Britain’s First Astronaut on the New Race to the Moon | Helen Sharman

Episode 360 A new era of space travel is finally upon us. NASA’s Artemis II rocket successfully launched 4 astronauts around the moon and back. Reacting to the historic news is Britain’s first astronaut, Helen Sharman. The high tech space race sees countries, once again, scrambling to be the first to land people on the lunar surface - but this time to set up a permanent base of operations. Artemis II has now tested the capabilities of the space craft. But Artemis III and IV are already in the works, with dozens of other launches planned, to get cargo and rovers to the moon. Unlike the space race of the 1960s, this one is very clearly between the US and China. And it’s clear that no matter who lands first, each country will continue their efforts to reach the surface and benefit from the so-called “lunar economy”. Rowan Hooper and Helen Sharman reflect on the success of the launch, nervousness about the spacecraft’s heatshields on reentry - and what it all signals for the future. She also explains why we need cooperation now, more than ever, to ensure international collaboration when we do finally start building on the lunar surface.

Rebecca Solnit On Why the Future Isn’t as Dark as It Looks

Episode 353 The world might feel dark right now, but life is actually getting better, rapidly. From the rise of feminism and antiracism to environmental movements and shifting understandings of gender, the Western world looks nothing like it did 75 years ago. Yet despite so many historic victories for rights and ideas in recent times, it often feels like we’re living in dark times - with progress that’s stalling or going backwards. In her new book, The Beginning Comes After the End: Notes on a World of Change, writer and activist Rebecca Solnit explores how for decades social movements reshaped the world in ways we often fail to notice. Solnit argues that we are witnessing nothing less than the slow dismantling of an old worldview. And it’s time we pay attention. Rowan Hooper speaks to Solnit about the power of a good story, our growing understanding of the interconnectedness of nature and humanity - and why recognising progress may be essential to shaping the future.

How ancient humans crossed the vast ocean; Brain training for dementia; Life of science legend Maggie Aderin

Episode 345 More than 8,500 years ago, ancient people crossed the ocean to the remote island of Malta for the first time. Long before compasses or sails were invented, these prehistoric people navigated the seas on logs, using the stars to travel vast distances. Recent findings show we’ve long underestimated the voyaging capabilities of stone-age hunter-gatherers. We discuss the many examples of ancient travel - and what this all tells us about the ancient mind. Could just one hour of brain training a day be enough to stave off dementia? For the first time, an intervention against dementia has been tested in a randomised control trial. Lasting an impressive 20 years, participants in the trial played a brain training game for just a few hours a week - and the results were remarkable. The legendary space scientist Maggie Aderin joins the show to discuss her new book, Starchild: My Life Under the Night Sky. The Sky at Night presenter discusses her motivation for writing a memoir, how her love of astronomy came about, what it was like as the only Black woman in her university class, her time working on the James Webb telescope - and more. Hosted by Rowan Hooper and Penny Sarchet, with guests Maggie Aderin, Michael Marshall and Alexandra Thompson.To read more about these stories, visit https://www.newscientist.com/ Learn more about your ad choices.

We Now Have Early Warning Signal Of Ocean Current Collapse

Episode 349 One of the most vital systems of ocean currents - needed to keep life in northern Europe stable - is at risk of collapse. And now we can predict when it’s going to happen. Thanks to the work of climate scientists, we now have a model that tells us when major shifts in the Atlantic Meridional Overturning Circulation (AMOC) are expected. The AMOC is the Atlantic conveyor belt that keeps northern Europe temperate. If it turns off, northern Europe would be plunged into freezing conditions that would decimate agriculture and upend life as we know it. And it’s becoming clear that it is already weakening. Rowan Hooper is joined by climate journalist Alec Luhn. Together they explain how the AMOC and gulf stream work, why fears of a “tipping point” have been growing in recent years, and how this new model helps us prepare for the worst. Also hear from climate scientist René van Westen, who co-authored the report in Nature.
