The salt caverns used to stockpile oil

Buried underground in caverns dug out of salt on the Gulf coast of the US are millions of barrels worth of crude oil. This is the Strategic Petroleum Reserve, built up in the late 1970s. Globally, at the end of 2025, global strategic oil stockpiles were estimated at 2.5 billion barrels, with China holding the most. With the Strait of Hormuz now closed for more than two months, global oil supplies are being squeezed. In March, as part of a co-ordinated move by members of the International Energy Agency to release 400 million barrels of oil to prevent price spikes, the US began releasing 172 million barrels from its strategic reserves. In this episode, we speak to Scott Montgomery, a former petroleum geologist who lectures in international studies at the University of Washington, about why these oil stockpiles were built up in the first place, and how they work.

Argentina’s inflation ‘miracle’ is more of a mirage

The month Javier Milei took over as president of Argentina in December 2023, monthly inflation was 25.5%. The annual rate for that year was 211%. Now, it’s plummeted to 32% – still very high, but more stable. Milei, a right-wing populist famous for wielding a chainsaw on stage to make a point about fiscal conservatism, made cutting inflation a central part of his campaign. And yet economists like Can Cinar from City St George's, University of London, warn that Milei’s battle against inflation is more of a mirage, than a miracle. In this episode, Cinar explains how Milei’s government managed to cut inflation by deliberately suppressing people’s wages, and the stark impact these policies are having on Argentinians.

The conspiracy theorists who feel vindicated by the Epstein files

As the revelations from the Epstein files continue to reverberate around the globe, those conspiracy theorists who were among the first to call for the release of information about Jeffrey Epstein's legal cases are feeling vindicated. Before his death, Epstein already featured in many fringe online forums, including those centred on the Qanon conspiracy narrative that the world is run by an elite cabal of child sex traffickers. Now, many in these communities are saying "We told you so." In this episode, Art Jipson, a sociologist at the University of Dayton in Ohio, who researches social movements and extremism, explains what happened when a real-life criminal case collided with an online community built on conspiracy theories. This episode was produced by Katie Flood, with assistance from Mend Mariwany. The executive producer was Gemma Ware. Mixing by Eleanor Brezzi and theme music by Neeta Sarl.

China’s long game on Trump’s tariffs

As Xi Jinping prepares to host Donald Trump for a delayed summit in Beijing on May 14-15, a lot has changed since the US president's last visit to China in November 2017. Trump's first trade war with China began in earnest the following year, ushering in a new era of trade tensions between the world's two largest economies. While Trump's second trade war raged in 2025, China reported a record trade surplus of US$1.2 trillion. Yes, direct trade with the US fell sharply, but China shifted its focus elsewhere, doubling down on an existing "great reallocation". In this episode, we speak to economist Jiao Wang at the University of Sussex, about how decisions China took over the past two decades meant it was able to protect itself from the worst of Trump's tariff wars. This episode was produced by Mend Mariwany and the executive producer was Gemma Ware. Mixing by Eleanor Brezzi and theme music by Neeta Sarl.

The pseudoscientific scale looksmaxxers use to rate each other

If you have teenagers in your life, they’ll probably have heard of the PSL scale. Or at least the language associated with it. Chad. Stacy. Normie. Subhuman. The PSL scale is a pseudoscientific attractiveness rating system used by looksmaxxers, men in a part of the manosphere who can go to extreme methods to change their appearance. The roots of this rating system lie in misogynistic online forums used by incels or involuntarily celibates, but now it’s all over social media. So how did the language of incels, and this one way of quantifying attractiveness and beauty, go so mainstream? In this episode, we speak to Jordan Foster, an associate professor of sociology at MacEwan University in Alberta, Canada, who researches social media, beauty and masculinity. He explains the origins of the PSL scale, where it fits into the manosphere, and how some looksmaxxing influencers are making money off it.

South Korea's birth rate is rising, but the population is still shrinking

South Korea’s very low birth rate and ageing population have long served as a cautionary tale for other governments worried that they’ll see similar demographic challenges. But now, for the second year running, more people in South Korea are having children. The 6.8% rise in births in 2025 is the largest rise since 2007, and has taken the country’s total fertility rate to 0.80, up from 0.75 in 2024. The news is being cautiously celebrated, but with South Korea’s overall population still shrinking, it is yet to reverse its demographic fortunes. In this episode, we speak to Stuart Gietel-Basten, a demographer and professor of social science and public policy at Hong Kong University of Science and Technology, about how South Korea has got to this point and some of the structural issues the country still faces.

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.

Quantum mechanics: does objective reality exist?

It is hard to shake the intuition that there's a real and objective physical world out there. If I see an umbrella on top of a shelf, I assume you do too. And if I don't look at the umbrella, I expect it to remain there as long as nobody steals it. But the theory of quantum mechanics, which governs the micro-world of atoms and particles, threatens this commonsense view. Featuring Chiara Marletto, Research Fellow of Physics, and Christopher Timpson, Professor of Philosophy of Physics, both at the University of Oxford, and Marcus Huber, Professor of Physics, TU Wien. This episode is presented by Miriam Frankel and produced by Hannah Fisher. Executive producers are Jo Adetunji and Gemma Ware.

Trump v Leo: the war of words over a just war

After Donald Trump took to social media to lambast Pope Leo's criticism of the Iran war, the pontiff told journalists "I'm not afraid of the Trump administration". Part of the war of words between Trump and Leo is a question over whether the Iran war is a just one. Just war theory, first articulated by St Augustine in the fifth century, outlines the church’s moral guidelines for political and military leaders to consider before choosing to go to war. But it’s not static, and the church’s own position has become more restrictive in recent years. In this episode, Gerard Powers, the director of Catholic Peace Building Studies at the University of Notre Dame in Indiana, explains how the Catholic church’s just war tradition evolved and the influence it’s had on US military thinking. Powers was a senior advisor on international policy for the U.S. Conference of Catholic Bishops during the Iraq war, and was involved in efforts to persuade the Bush administration not to invade. He sets out the difficulty now facing Catholics serving in the US military, whose archbishop has now spoken out against the war they’re being asked to fight This episode was produced by Katie Flood and Mend Mariwany and the executive producer was Gemma Ware.
