A show for curious minds, from The Conversation. Each week, host Gemma Ware speaks to an academic expert about a topic in the news to understand how we got here.

Timothy Piatkowki was scrolling when a targeted ad landed in his feed. Cheap peptides! Straight from the factory! Naturally, he started a chat with the dealer and found himself deep in the world of a thriving grey market.

The more he found out, the less he realised we know about what’s really in these tiny drug vials being shipped around the world.

You can see screen grabs of Tim’s exchanges with the peptide seller in a fascinating visual story he’s written for us about the experience. Read it here.

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.

Save our brains: how dangerous is sport?

Three months ago, Andy Burnham’s desk was filled with the business of running Greater Manchester. Buses. Housing. Policing. This mayoral region in the north of England is home to 3 million people and Burnham, a former minister in the Labour governments of Tony Blair and Gordon Brown, has been its mayor for nearly a decade.

But after a whirlwind ten weeks, Burnham travelled to Buckingham Palace on July 20 to meet King Charles, who appointed him as Britain’s new prime minister.

At the heart of Burnham’s plans for power lies Manchesterism, a political philosophy that centres on giving cities and towns outside London more political control. In this episode, we explore how running Greater Manchester shaped Andy Burnham’s politics with researchers Kirsty Fairclough from Manchester Metropolitan University and Philip Brown from the University of Huddersfield. They assess what Burnham achieved as mayor and discuss whether a philosophy designed around one city can work on a national level for the UK.

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?

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.

A new youth protest movement in India that started as online satire is now staging an ongoing sit-in in New Delhi calling for the resignation of India’s education minister.

The Cockroach Janta Party (CJP) was launched in late May by Abhijeet Dipke, a graduate of Boston University, in response to alleged comments by India's chief justice, Surya Kant, comparing unemployed young Indians to cockroaches. Dipke launched a parody political party, calling on all cockroaches to unite, which led to street protests in cities including Delhi, Pune, Jaipur and Bengaluru.

The CJP latched onto mounting anger in India at a series of issues affecting exams, including the secondary school leaving exam, which has affected thousands of people and been linked to suicides. But the movement has also tapped into the anger of a generation of graduates who’ve done everything right but still can’t find work that matches their aspirations.

In this episode economist Rosa Abraham at Azim Premji University, explains how India’s jobs crisis is fuelling this new youth protest movement.

Cockroach party hits nerve with angry young Indians

When Australia banned under 16-year-olds from using social media in December 2025, it became a test case for a policy now being pursued by governments around the world. This week, the UK announced a similar social media ban from 2027.

So how’s it going in Australia? Have the teenagers emerged from a phone-lit glow to reengage in the real world? And what kind of difference is it having on their mental health?

In this episode, we speak to Susan Sawyer, a professor of adolescent mental health at the University of Melbourne, who is running a number of ongoing studies examining the way young people and their parents are reacting to Australia’s ban.

Teens are still on social media, but does that mean Australia's ban has failed?

When Roberto Baggio missed a penalty in the 1994 Fifa World Cup final at the Rose Bowl in Pasadena, California, more than 94,000 people were there to watch Italian heartbreak and Brazilian ecstasy.

To this day, no other World Cup has been as well attended as the 1994 tournament. Tickets were cheap and abundant, and despite the relatively low profile of the game in the US compared to sports like baseball or basketball, people went along to see what it was all about.

Now, three decades later, as the 2026 World Cup returns to North America with games across Mexico, Canada and the US, soccer has grown a much larger and more dedicated fan base in America.

In this episode, we speak to John Sloop, a professor of communication studies at Vanderbilt University in Nashville, Tennessee, and historian of soccer and its fans in the United States, about what’s changed for the men’s game in the US and whether the popularity has staying power.

As health workers in the Democratic Republic of Congo (DRC) continue to battle an ongoing Ebola outbreak, scientists around the world are racing to develop a vaccine against the strain of the virus that’s causing it.

Two approved vaccines exist for Ebola, but they target the Zaire strain of the virus, not the Bundibugyo strain causing the 2026 outbreak, which has so far killed 61 people with 359 confirmed cases in the DRC and neighbouring Uganda.

In this episode, we speak to two scientists at the Oxford Vaccine Group at the University of Oxford, Teresa Lambe and Rebecca Makinson, who are developing a vaccine candidate for Bundibugyo virus. On June 1, they were among three research groups to receive fast-track funding from the Coalition for Epidemic Preparedness Innovations, alongside Moderna and IAVI.

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.
