The Conversation Weekly

Twenty years ago, extreme and violent pornography was largely confined to a niche corner of the internet. Today, depictions of strangulation and sexual violence have become mainstream. So how did porn become so extreme?

In this episode, Clare McGlynn, professor of law at Durham University in the UK, explains how the algorithms and business models of major porn platforms are helping to normalise increasingly violent content. She also discusses its impact on young people’s sexual behaviour, and unpacks new UK laws that target porn depicting strangulation and other forms of sexual violence.

Content warning: This episode contains descriptions of sex and sexual violence.

In Tennessee, death row inmate Christa Pike survived an attempt to execute her by lethal injection in late September. Meanwhile, plans to livestream a US military execution recently sparked outrage, prompting President Donald Trump to walk back the broadcast.

These controversies come after a sharp rise in executions in the United States in 2025, reversing a decline that had lasted two decades.

In this episode, historian Carolyn Strange, emeritus professor at the Australian National University, talks us through the history of capital punishment in America, from public hangings to lethal injections. She explains why failed executions are nothing new, what's driving the resurgence, and why the death penalty remains so deeply political.

In the western Canadian province of Alberta, a political battle is playing out on people’s front lawns. Separatists are flying the royal blue Alberta flag, others the red and white maple leaf of Canada to show their support for a united Canada.

It's all because a populist right-wing political movement wants Alberta to break away from the rest of the country. On October 19, Albertans will vote in a referendum on whether to have a referendum on independence.

So how did the relatively small separatist movement gain so much political influence? Why do they want to leave Canada? And what does Donald Trump have to do with all of this?

Listen to Jared Wesley, a professor of political science at the University of Alberta, on the origins of the Alberta separatist movement.

The multi-billion dollar AUKUS defence deal between the US, UK and Australia is one of the most significant in our modern history.

The three countries wanted to curb China’s growing military presence in the Indo-Pacific. To do it, Australia was going to get new nuclear-powered submarines.

But in the five years since the agreement was first announced, it’s been anything but smooth sailing.

In this week's episode of The Conversation Weekly, we speak with Hugh White, a security and defence analyst at the Australian National University, to explore how the secretive deal was struck and why it's proving so controversial.

To most of the world, former Bosnian Serb military general Ratko Mladić was a brutal war criminal whose actions during the Bosnian War killed thousands.

For others, he was a martyr who defended the Serbian people.

In late August, the 84-year-old died while serving a life sentence in The Hague for war crimes and crimes against humanity.

He was laid to rest in Belgrade earlier this week with full military honours - a move which angered the families of the victims of his crimes.

On this week's episode of The Conversation Weekly, why a war criminal being celebrated by some as a hero and how this is reopening old wounds in one of Europe’s most divided regions.

It’s the middle of the night in April 2023 in the East China Sea.

A North Korean-linked oil tanker sailing under another country’s flag suddenly goes dark. It stops transmitting its location and simply vanishes from the map.

Ten days later, the New Konk reappears on global tracking screens. It’s signal places it off the coast of southern China.

Except it’s not. It’s actually in a bay hundreds of kilometres away.

Commonly known as a “shadow fleet”, the New Konk is part of a clandestine network of vessels which are used to evade international sanctions.

It was 1967, and country musician Porter Wagoner was introducing a guest on his weekly TV show.

The camera cuts to a woman with big, blonde beehive, wearing a magenta mini dress with the same shade of lipstick to match. It was in that moment a star was born.

Her name was Dolly Parton. In the following decades after that performance, Parton went on to become the “Queen of Country”.

In this week's bonus episode of The Conversation Weekly, musicologist and Professor of Music at Hamilton College Lydia Hamessley explains the music that made Dolly Parton a global superstar.
