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.

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: co-opt the military

In November, six Democratic lawmakers recorded a video directed at members of the US military and intelligence agencies. In it, they issued a blunt reminder: "The laws are clear: […] You must refuse illegal orders." The lawmakers were issuing the warning against the backdrop of US airstrikes on boats off the coast of Latin America the Trump administration claims are suspected drug runners. Many Democrats and legal experts, however, argue these strikes are illegal. Since returning to office, Trump has successfully expanded his power over his own party, the courts and the American people. Now, like many autocrats around the world, he’s trying to exert control over the military. Mentioned in this episode: The Making of an Autocrat Follow the feed so you don't miss an episode.

Was the Gulf blindsided on Iran?

As Israel and the US continued to bomb Iran after killing the country's supreme leader Ali Khamenei, Iran lashed out at its neighbours with multiple drone strikes, including against the US embassy in Riyadh. Saudi Arabia and Iran have a long and bitter rivalry. Yet, in recent years, the Saudis had begun building new diplomatic relationship with Iran, even as they and other Gulf states continued to host American military bases, and court American investment. Now the Gulf states find themselves in the middle of the very regional conflict many of its leaders hoped to avoid. It's one which threatens longstanding efforts to cement the Gulf as a hub for finance, travel and tourism, and as an oasis of security. Were they blindsided? Or did some actually want the US to attack Iran? With the US and Israel seemingly calling the shots, what will the Gulf states do now? In today's episode, we speak to Simon Mabon, a professor of international relations at Lancaster University in the UK and expert in Saudi-Iran relations, about how the Gulf's delicate balancing act between the US and Iran came toppling down. This episode was written and produced by Mend Mariwany and Katie Flood. The executive producers was Gemma Ware. Mixing by Eleanor Brezzi and theme music by Neeta Sarl.

A lost US military base under Greenland's ice sheet

In the summer of 1959, a group of American soldiers began carving trenches in the Greenland ice sheet. Those trenches would become the snow covered tunnels of Camp Century, a secret Arctic research base powered by a nuclear reactor. Camp Century operated for six years, during which time the scientists based there managed to drilling a mile down to collect a unique set of ice cores. But by 1966, it had been abandoned, deemed too expensive and difficult to maintain. Today, Donald Trump’s territorial ambitions for Greenland continue to cause concern and confusion in Europe, particularly for Denmark and Greenlanders themselves who insist their island is not for sale. One of the attractions of Greenland is the gleam of its rich mineral wealth, particularly rare earth minerals. Now that Greenland’s ice sheet is melting due to global warming, will this make the mineral riches easier to get at? In this episode, we talk to Paul Bierman, a geologist and expert on Greenland’s ice at the University of Vermont in US. He explains why the history of what happened to Camp Century – and the secrets of its ice cores, misplaced for decades, but now back under the microscope – help us to understand why it’s not that simple.

What your body odour says about you

Body odour has a reputation problem. It is often treated as a hygiene failure or a social offence. In reality, it is biology at work, plus a big helping of culture. And yet people online are trying chlorophyll shots to make their BO smell better. Hosts Katie Edwards and Dan Baumgardt discuss what evidence there is behind this, plus some of the health conditions that can affect body odour. And we talk to Mats Olsson, a professor of experimental psychology at the Karolinska Institutet in Stockholm, who studies how humans perceive body odour. Strange Health is a podcast from The Conversation is an independent, not-for-profit news organisation. Full credits for this episode available here.

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.

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.

Is time an illusion?

Without a sense of time, leading us from cradle to grave, our lives would make little sense. But on the most fundamental level, physicists aren't sure whether the sort of time we experience exists at all. We talk to three experts and find out if time could potentially be moving backwards as well as forwards. Featuring Sean Carroll, Homewood professor of natural philosophy at Johns Hopkins University, Emily Adlam, postdoctoral associate of the philosophy of physics at Western University and Natalia Ares, Royal Society university research fellow at the University of Oxford. This episode was presented by Miriam Frankel and produced by Hannah Fisher. Executive producers are Jo Adetunji and Gemma Ware.
