Are we alone in the universe?

Scientists have long referred to the Goldilocks zone – the region around a star where conditions are not too hot and not too cold but “just right” for life. Joined by a live audience at the Cheltenham Science Festival in the UK, Tom Whipple asks what are the true limitations of alien life? How do we spot it? And have we been looking too narrowly? Planetary scientist at MIT Sara Seagar discusses her team’s mission to Venus where, on the surface, temperatures can reach 500 degrees Celsius and it rains sulphuric acid. Above the rain, up in the clouds, Sara Seagar tells us how there could be life. And Lewis Dartnell, Professor of astrobiology at the University of Westminster, describes how he looks for extremophiles. These are organisms on earth that are found in places we once thought impossibly hostile to life. Plus, the missions to find life on Mars....

Testing testosterone testing

Secretary of Defence Pete Hegseth has announced that the US military will be screening military personnel aged 30 and older for testosterone deficiency. Those found with low testosterone levels will be offered voluntary hormone replacement therapy. The secretary says this is to ensure “a healthy, capable, and decisively dominant fighting force”. Tom Whipple is joined by Professor Joe Herbert from the University of Cambridge to discuss why jacking soldiers up with testosterone may or may not be the best idea. Marine Biologist Kathryn Ayres, from the non-profit organisation Beneath the Waves, describes a newly observed behaviour in orcas in which they collaboratively swim so hard into a dead sunfish it explodes. Is it a teachable moment for their young or is it just for fun? Finally, we have Kit Yates, our resident mathematician, to reassure Tom that although AI might one day actually kill us all, at least it can disprove an 87-year-old mathematics conjecture.

How might we spot nukes in space?

A few years ago a satellite speeding through the Van Allen belt in earth orbit raised concerns that it may include a nuclear weapon. An explosion in that orbit would take out much of our global space infrastructure. The Outer Space Treaty of 1967 specifically prohibits such a thing, but it has proven technologically impossible to verify and monitor over the decades. Tom Whipple is joined by Prof Areg Danagoulian, Associate Professor of Nuclear Science and Engineering at MIT to explore a clever concept to spot such a thermonuclear device in orbit that he has published in this month’s Nature journal. Also on the show, Professor of Science Communications Gareth Mitchell discusses how the way toddlers waddle can teach robots how to play football, and how to win. He also examines a new global database on food consumption which aims to help answer some of the world’s most pressing questions on our diets and the environment.

Are we one step closer to creating life in a lab?

Synthetic biologist Kate Adamal and her team at the University of Minnesota published their research into the lab-created ‘SpudCell’ in a significant step towards building life from scratch. Science journalist, Kai Kupferschmidt, joins us to discuss the implications of this research, as well as the controversies. Nature reporter Lizzie Gibney tells us how science has helped us better understand the route that the famous Carthaginian general, Hannibal – and not forgetting his elephants – took across the Alps. Plus, in this week’s scout of science stories behind the ‘beautiful game’ we learn of research carried out at a Tokyo football match, monitoring seismic waves made by the vigorous celebrations of thousands of fans.

How do you immortalise natural history?

During this year’s visit to the Royal Society Summer Science Exhibition in London, Tom Whipple discovers how sea urchins are being used to develop techniques to digitally preserve natural history, why we haven’t got robot butlers just yet, and what it takes to bottle lightning. Plus, in his ongoing quest to assemble a World Cup squad of science Tom recruits health reporter James Gallagher to scout out the best football science from around the world. This week, we want to know if there is robust evidence for a home advantage. We speak with Associate Professor of Cell & Developmental Biology Laura Porro from University College London, Dr Alice Leavey and Dr Fernando Alvares from the University of Southampton, Professor Ingmar Posner who leads the Applied Artificial Intelligence Lab at the University of Oxford and Dr Daniel Mitchard who is co-lead of Cardiff University’s Lightning Laboratory.

Can we engineer ourselves out of a heatwave?

As the UK and Europe battles with extreme weather warnings, is it time for us to consider some more extreme tactics to tackle the heat? Tom Whipple is joined by Mark Maslin, Professor of Earth System Science at University College London, to explore if solar geoengineering can help. Also on the show, science journalist Lizzie Gibney discusses the "Salah effect", when exposure to celebrities from stigmatised groups can help increase tolerance. She also examines new research into how the atom nucleus contain energy which can be used for telling the time. Plus, how laughter in great apes may have paved the way for the evolution of complex human language. Presenter: Tom Whipple Producer: Katie Tomsett, Alex Mansfield & Kate White Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth

Finding the evidence for the social media ban

After this week’s announcement that under-16s will be banned from major social media platforms, we delve into the evidence behind the ban with Professor Amy Orben, Programme Leader of the Digital Mental Health Group at the University of Cambridge, and Dr Catherine Sebastian, Head of Evidence at Wellcome. Also on the show, what can penalty shoot-outs teach us about international diplomacy? And how does the valuation of a football player impact the number of crashes seen after their team plays? Professor of Mathematical Sciences at Bath and football fan, Kit Yates, joins Tom to assemble their very own World Cup squad of science. Presenter: Tom Whipple Producers: Kate White, Katie Tomsett, Keiran Manetta-Jones Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth

How do you build an unbuildable tower?

After 144 years the tallest tower on the Sagrada Familia is finally complete, but when Gaudi first designed it, the technology to build the tower didn’t exist. We’re joined by Tristram Carfrae, structural engineer and designer at Arup who was tasked with this impossible feat over a decade ago. With the reappearance of screwworm in North America, we ask – is it ever acceptable to intentionally drive a species to extinction? Tom is joined by Dr Gregory Kaebnick from the Hastings Center for Bioethics to dive into the science that could make it happen and the ethics stopping us. Four in five of us will check the weather daily, but do we really know what our apps are telling us? Meteorologist Simon King guides us through the complex models behind these forecasts that govern our daily decisions. Plus, science journalist Caroline Steel is in the studio bringing us the scientific discoveries the headlines missed, but that you need to know. Presenter: Tom Whipple Producer: Kate White Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth

They steal billions: Cyber Hack investigates the alleged cyber gangs and the heists and hacks they’re accused of carrying out. No one is said to be safe. From Hollywood studios, to international banks, from crypto exchanges to hospitals and diamond companies, law enforcement agencies say they cause chaos around the globe. Who will be next? And where is the money going? Latest season: A global campaign of cybercrime nets a ruthless gang of hackers millions of dollars but leaves hospitals helpless, businesses on the brink and a country on its knees. That’s until an act of apparent revenge exposes a giant trove of their secret communications. Previously on Cyber Hack: Evil Corp. The Russian Evil Corp is accused of being a family crime gang, responsible for stealing hundreds of millions of dollars. Law enforcement agencies say they are “the most pervasive cybercrime group to ever have operated”. No one is off limits – not even a group of nuns in Chicago. The Lazarus Heist. This hacking group is said to be behind the biggest crypto heist in history, stealing billions of dollars in the process. Investigators blame North Korea’s state-backed hackers The Lazarus Group, and say the stolen money is being used to finance its nuclear weapons and missile development programs. Pyongyang denies involvement. Among the Lazarus Group’s many targets are Hollywood’s Sony Entertainment and the Bank of Bangladesh. ATMs are cleaned out of money, while its operatives live double lives in a hacker hotel. But where does the money trail lead?

The comedy podcast that takes history seriously. In each episode of You’re Dead to Me from BBC Radio 4, Greg Jenner is joined by a comedian and an expert historian to learn and laugh about the past. History isn’t just about dates and textbooks – it’s about extraordinary characters, amazing stories, and some very questionable fashion choices. How long did it take to build an Egyptian pyramid? What does the Bayeux Tapestry reveal about medieval life? Why did it take nearly half a millennium for Joan of Arc to become a saint? And was Catherine the Great really all that great? Whether you want to explore ancient landmarks like Stonehenge and Machu Picchu, dance through the history of Broadway and Bollywood, or find out how the Tudors rose to power, Greg and his guests promise to teach you something new that you won’t have heard in history lessons. Previous episodes of You’re Dead To Me have covered everything from royals to revolutionaries, actors to activists and divas to dictators. Take a stroll through the history of high-heeled shoes or get the scoop on the history of ice cream. Maybe you’d like to paint like the cave artists of the Palaeolithic era, work out like a Victorian bodybuilder, or fight like a Spartan? We’ve even hosted a special, live episode with the BBC Concert Orchestra to explore the dramatic life of Wolfgang Amadeus Mozart. Whatever your historical interests, Greg and his guests make even the trickiest topics easy to follow. Join them for a history lesson that’s as entertaining as it is enlightening - with no homework required.
