The Making of One Nation: the unlikely rise of Australia’s Pauline Hanson

From a fish and chip shop in regional Queensland to the heart of Australian politics: this is the unlikely story of One Nation, Australia's most controversial minor party. For thirty years, One Nation and Pauline Hanson have been ridiculed, dismissed and shut out. Now, no one is laughing. This week we're running the first episode of The Making of One Nation, a new series from The Conversation hosted by Ashlynne McGhee. She explores how a party built on fear and grievance thrived, died and rose again to upend Australian politics. Hanson's infamous 1996 maiden speech to the Australian Senate — warning that Australia was "being swamped by Asians" — still echoes through Australian political life. 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? We hear from Anna Broinowski, documentary maker and senior lecturer at the School of Art, Communication and English at the University of Sydney, who made a documentary and wrote a book about Hanson.

Theory of everything: do we really need one?

The quest for a theory of everything – explaining all the forces and particles in the universe – is arguably the holy grail of physics. While each of our main theories of physics works extraordinarily well, they also clash with each other. But do we really need a theory of everything? And are we anywhere near achieving one? Featuring Vlatko Vedral, a professor of physics at the University of Oxford and Chanda Prescod-Weinstein, an assistant professor in physics and astronomy and core faculty in women's and gender studies at the University Of New Hampshire. 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.

The Making of One Nation: enter the outside

Nearly thirty years on, Hanson's infamous maiden speech — warning that Australia was "being swamped by Asians" — still echoes through Australian political life. 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?

Mystery covid methane spike solved

Six years ago, as countries around the world went into COVID lockdowns, the air got cleaner. Factories slowed down, roads emptied and aeroplanes were grounded. As people stayed home, the world burned fewer fossil fuels and so carbon dioxide emissions dropped. But something else was also happening in the atmosphere. Levels of methane, an extremely potent greenhouse gas that warms the planet even faster than CO2, rose faster in 2020 than at any point since records began in the 1980s. And methane levels kept on rising during 2021 and 2022. Ever since, scientists have been trying to piece together what caused this sudden mysterious increase in methane. Now, they think they have the answer – and it was partly due to COVID lockdowns. In this episode, we speak to Philippe Ciais, a researcher at the Laboratory for Environmental and Climate Science at Université Paris-Saclay in France, and one of the authors of a new study in the journal Science about the spike in methane levels, who explains how they solved the mystery. This episode was written and produced by Mend Mariwany and Katie Flood and Gemma Ware was the executive producer. Mixing by Eleanor Brezzi and theme music by Neeta Sarl.

Artemis II: NASA’s long road back to the Moon

Final preparations are underway for NASA’s Artemis II mission, the first crewed mission around the Moon for more than 50 years. Four astronauts, three men and one woman, will spend 10 days aboard the Orion spacecraft, going further into space than any other humans as they orbit the Moon and return to Earth. The mission is the next step of the Artemis programme, which plans to land astronauts back to the Moon by 2028. China has its own programme targeting a full crewed mission to the lunar surface by 2030. In this episode, we speak to Scott Pace, director of the Space Policy Institute at George Washington University about why the US is going back to the Moon. Pace worked in space policy for the George W. Bush Administration, followed by a stint at NASA before his appointment as the executive secretary of the National Space Council during the first Trump administration, where he worked on the launch of the Artemis programme. This episode was written and produced by Katie Flood and Gemma Ware was the executive producer. Mixing by Eleanor Brezzi and theme music by Neeta Sarl.

How the US cloned Iran's drones

The day after the US began bombing Iran, US Central Command confirmed it had used a new, cheap type of kamikaze drone called a Lucas for the first time in a combat operation. These drones were made in America, but their roots actually lie in Iran – they are reverse engineered copies of an Iranian drone called a Shahed that the Russians have also been using to bomb Ukraine. In this episode, PhD researcher and military expert Arun Dawson at King's College London explains how the Iranians developed the Shaheds, why the US decided to copy them, and what role these low-cost drones might play in the future of warfare. This episode was written and produced by Mend Mariwany and Gemma Ware was the executive producer. Mixing by Eleanor Brezzi and theme music by Neeta Sarl.

The Making of an Autocrat: beat the courts

In democratic systems, the courts are a vital check on a leader’s power. They have the ability to overturn laws and, in Donald Trump’s case, the executive orders he has relied on to achieve his goals. Since taking office, Trump has targeted the judiciary with a vengeance. He has attacked what he has called “radical left judges” and is accused of ignoring or evading court orders. The Supreme Court has already handed the Trump administration some key wins in his second term. But several cases now before the court will be pivotal in determining how much power Trump is able to accrue – and what he’ll be able to do with it. As Paul Collins, a Supreme Court expert from the University of Massachusetts-Amherst, explains in episode 4 of The Making of an Autocrat: "It’s all about presidential power. And that’s really significant because it’s going to enable the president to basically inject a level of politics into the federal bureaucracy that we frankly haven’t really seen before in the US." This episode was written by Justin Bergman and produced and edited by Isabella Podwinski and Ashlynne McGhee. Sound design by Michelle Macklem.

What is the vagus nerve and can you really reset it?

The vagus nerve has become the internet’s favourite body part. On social media, it is everywhere. People hum into their phones, gargle with theatrical enthusiasm, dunk their faces into bowls of ice water and poke at their ears in the hope of “activating” it. So in this episode we focus our attention on the body’s longest cranial nerve and ask a simple question: what does the vagus nerve actually do, and can we really hack it? Hosts Katie Edwards and Dan Baumgardt turn this week to Arshad Majid, a professor of cerebrovascular neurology at the University of Sheffield and an expert in vagus nerve stimulation.
