How celebrities like Taylor Swift are fighting back against AI deepfakes

When Taylor Swift launched her latest album, The Life of a Showgirl, in October 2025, she recorded two short clips to promote it. One for Amazon Music began with “Hey, it’s Taylor Swift”. Another, for Spotify with “Hey, it’s Taylor”. These two phrases may sound a little mundane, but they’re now at the frontline of a legal fightback by celebrities like Swift against AI deepfakes. In April, Swift’s intellectual property company, TAS Right Management, applied to the US Patent and Trademark office to trademark them as registered sound marks, along with a photo of her, from her recent Eras tour. In this episode, we speak to intellectual property expert Graeme Austin, a professor of law at the University of Melbourne and chair of private law at Victoria University of Wellington to understand why Swift took this route, and the different ways celebrities are trying to protect themselves against AI deepfakes. And if you’re not a celebrity with a large legal team, what can you do? This episode was written and produced by Gemma Ware and Mend Mariwany.

Save our brains: how dangerous is sport?

With growing evidence about concussion, repetitive head impacts and long-term brain disease, have we underestimated the risks of sport all along? How did we get here, what do we really know about head injuries and given the risks, is it time to rethink children’s participation in sport? In this episode, we chat to Alan Pearce, a neuroscientist and Adjunct Professor at Swinburne University of Technology in Melbourne who has been researching sports-related concussions for more than two decades. This episode was written and produced by Isabella Podwinski. Mixing by Michelle Macklem and theme music by Neeta Sarl. You can sign up here for a free daily newsletter from The Conversation.

The anatomy of a super El Niño

El Niño has begun and forecasters predict a more than 60% chance that the naturally occurring phenomenon could become a very strong, or super El Niño later in 2026. El Niño begins with warmer water in the Pacific Ocean near the equator and can have a cascade of dramatic effects on the world’s weather. But what chain of events has to happen for high temperatures in the Pacific to translate into severe floods, droughts and storms around the world? And what role does climate change play in El Niño? In this episode, Ioana Colfescu, an expert in climate and machine learning at the University of St Andrews and the University of Edinburgh, explains how El Niño works and what it could mean for the world.

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. This episode was written and produced by Gemma Ware and Katie Flood with production assistance from Katie Flood. Mixing by Eleanor Brezzi and theme music by Neeta Sarl.

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. Social media and platform production by Alice Mason, sound design by Eloise Stevens and music by Neeta Sarl. A transcript is available here.

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.

Will we ever have a fundamental theory of life and consciousness?

What’s the difference between a living collection of matter, such as a tortoise, and an inanimate lump of it, such as a rock? They are, after all, both just made up of non-living atoms. The truth is, we don’t really know yet. Life seems to just somehow emerge from non-living parts.

How high can a volcano throw lava up in the air?

Erupting volcanoes spew molten lava, gas and rocks up into the air. But just how high can the lava go and how do eruptions work? That’s what eight-year-old Thomas from Leeds in the UK wanted to know. Thomas joined our host Eloise to put his question to volcanologist Martin Mangler from the University of Southampton. If you'd like to join in with the experiment in this episode, you'll need some bicarbonate of soda, some vinegar, honey, a bottle or mug and a straw, to hand. A podcast from The Conversation, the independent not-for-profit news organisation that brings you news and analysis straight from academic experts. Full credits available here. This season is supported by the University of Southampton in the UK, a world-leading research-intensive university with a global network of international students and campuses in Malaysia and Delhi.

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.

But who was Pauline Hanson before she became a phenomenon, and what did she actually represent? Was she a cause of a new kind of politics, or a symptom of one already forming?
