A lost US military base under Greenland's ice sheet

In the summer of 1959, a group of American soldiers began carving trenches in the Greenland ice sheet. Those trenches would become the snow covered tunnels of Camp Century, a secret Arctic research base powered by a nuclear reactor. Camp Century operated for six years, during which time the scientists based there managed to drilling a mile down to collect a unique set of ice cores. But by 1966, it had been abandoned, deemed too expensive and difficult to maintain. Today, Donald Trump’s territorial ambitions for Greenland continue to cause concern and confusion in Europe, particularly for Denmark and Greenlanders themselves who insist their island is not for sale. One of the attractions of Greenland is the gleam of its rich mineral wealth, particularly rare earth minerals. Now that Greenland’s ice sheet is melting due to global warming, will this make the mineral riches easier to get at? In this episode, we talk to Paul Bierman, a geologist and expert on Greenland’s ice at the University of Vermont in US. He explains why the history of what happened to Camp Century – and the secrets of its ice cores, misplaced for decades, but now back under the microscope – help us to understand why it’s not that simple. This episode was written and produced by Mend Mariwany and Gemma Ware with editing help from Katie Flood. Mixing by Michelle Macklem and theme music by Neeta Sarl.

LSE IQ: is AI destroying the planet?

AI is transforming the world around us, offering increased productivity and promising to tackle difficult problems like global warming. But behind the scenes, its environmental costs are mounting. From massive energy use to vast quantities of water required to cool data centres, AI’s footprint is growing fast. So, in an age of water scarcity and climate crisis, can we justify this technological boom? As The Conversation Weekly team takes a production break in August, we're delighted to bring you an episode of LSE IQ, an award-winning, monthly social science podcast produced by a team from the London School of Economics and Political Science. Each episode they ask leading social scientists and other experts to answer one intelligent question and speak to people affected by the issues explored. Like artificial intelligence. In this episode of LSE IQ which aired in early May, producer Anna Bevan sets out to find out the environmental costs of AI. This episode was produced and edited by Anna Bevan, with script development from Sophie Mallet and on location sound recording from Oliver Johnson. Mixing help for this episode for The Conversation from Eloise Stevens. Subscribe to LSE IQ here.

How Iran shut down the internet

On January 8, as thousands of Iranians took to the streets in nationwide protests, the government cut off the internet. Under cover of digital darkness, the Iranian regime launched a brutal and deadly crackdown against anti-government protesters. After three weeks of internet blackout, reports from web traffic monitor Netblocks suggest that the internet is slowly coming back online but predominantly for government-approved users. Yet for most of the shutdown, banks and some local government websites and apps still worked. And that’s because Iran is developing its own, national internet, cut off from the rest of the world. In this episode, we speak to Amin Naeni, a PhD candidate researching digital authoritarianism at Deakin University in Australia, about how Iran built one of the world’s most sophisticated systems of digital control. This episode was written and produced by Mend Mariwany and Gemma Ware with editing help from Katie Flood. Mixing by Michelle Macklem and theme music by Neeta Sarl.

Where support for Germany’s far-right AFD is growing and why

As Germany heads towards elections on February 23, the far-right Alternative for Germany (AFD) is polling in second place on 20% of the national vote. The AFD's roots are in nationalistic and racist movements. It continues to take an ultra anti-immigration stance and is calling for "demigration" – effectively the deportation of migrants. In this episode, Rolf Frankenberger, an expert on right-wing extremism at the University of Tübingen in Germany, talks to Laura Hood, senior politics editor at The Conversation, about where the AFD draws its support from and what type of Germany it wants to return to. This episode was Mend Mariwany and Gemma Ware with sound design by Michelle Macklem. Our theme music is by Neeta Sarl. Full credits for this episode are available.

How the world fell in love with plastic without thinking through the consequences

Every year, 400 million tons of plastic are produced worldwide, and every year, approximately 57 million tons of plastic waste is created. And yet in November, the latest round of negotiations to agree the first legally binding international treaty on plastics pollution collapsed. So what can we really do about the plastics pollution problem? In this episode we sat down with Mark Miodowonik, professor of materials and society at UCL in the UK, to understand the history of plastic, how it’s shaped our lives, and what can be done to make sure more plastic is recycled and less ends up polluting the planet.

Fundamental constants: is the universe fine tuned for life to exist?

Imagine a universe with extremely strong gravity. Stars would be able to form from very little material. They would be smaller than in our universe and live for a much shorter amount of time. But could life evolve there? It after all took human life billions of years to evolve on Earth under the pleasantly warm rays from the Sun. Now imagine a universe with extremely weak gravity. Its matter would struggle to clump together to form stars, planets and – ultimately – living beings. It seems we are pretty lucky to have gravity that is just right for life in our universe. Featuring Fred Adams, professor of physics, University of Michigan, and Paul Davies, professor of physics, Arizona State University. This episode was presented by Miriam Frankel and produced by Hannah Fisher. Executive producers are Jo Adetunji and Gemma Ware. Social media and platform production by Alice Mason, sound design by Eloise Stevens and music by Neeta Sarl. A transcript is available here.

What will batteries of the future be made of?

The majority of the world’s rechargeable batteries are now made using lithium-ion. Most rely on a combination of different rare earth metals such as cobalt or nickel for their electrodes. But around the world, teams of researchers are looking for alternative – and more sustainable – materials to build the batteries of the future. In this episode, we speak to four battery experts who are testing a variety of potential battery materials about the promises they may offer. Featuring Laurence Hardwick from the University of Liverpool, Robert Armstrong from the University of St Andrew's, Ulugbek Azimov from Northumbria University and Bill Yen from Stanford University. Applications are now open for early career researchers to submit their projects for the Prototypes for Humanity 2025 awards and showcase in Dubai. This episode was written and produced by Gemma Ware with assistance from Mend Mariwany and Katie Flood. Sound design and mixing by Eloise Stevens and theme music by Neeta Sarl.
