As Donald Trump gives oxygen to unproven theories about what might be behind a recent rise in autism cases, experts repeatedly point to the changing nature of how autism is diagnosed and viewed.

A key moment in the history of autism diagnosis was the publication in 1994 of a new version of the Diagnostic and Statistical Manual of Mental Disorders. It's a reference book of psychiatric conditions and how to diagnose the...

Donald Trump is not letting up pressure on the US Federal Reserve. He's taken efforts to fire one of its governors, all the way up to the US Supreme Court.

Trump's clash with the Fed echoes pressure that Richard Nixon put on the central bank in the 1970s to lower interest rates. In this episode, Cristina Bodea, professor of political science at Michigan State University, why that moment – and the inflation spike that followed – bec...

With France, the UK, Australia and Canada expected to recognise an independent Palestinian state at UN General Assembly in New York, what are the origins of the state they plan to recognise?

In this episode, Palestinian-American historian Maha Nassar from the University of Arizona describes the events leading up to the original declaration of Palestinian independence in 1988, including the compromises made within the Palestinian li...

Police in Australia are continuing a huge manhunt in the mountains for Dezi Freeman, a man accused of killing two police officers and injuring a third in late August.

Freeman identifies as a sovereign citizen, someone who believes they aren't subject to the law.

In this episode we speak to criminologist Keiran Hardy from Griffith University about the origins of the sovereign citizen movement in the US, how it spread to Australi...

As China invited world leaders to a vast military parade marking the end of the second world war on September 3, President Xi Jinping said China is "never intimidated by bullies" and would "stand by the right side of history". In a coded message about China's territorial ambitions over Taiwan, Xi added that "the great rejuvenation of the Chinese nation was unstoppable".

China and Taiwan both claim their forces bore the true burden o...

If you’ve ever experienced a state of creative flow, perhaps when writing, playing music, or even gardening, you’ll know that it feels like everything just clicks into place. But what is actually happening inside the brain?

This week, we're re-running an episode first published in June 2024 featuring neuroscientist John Kounios at Drexel University in the US. He scanned the brains of jazz musicians as they were improvising, and reve...

AI is transforming the world around us, offering increased productivity and promising to tackle difficult problems like global warming. But behind the scenes, its environmental costs are mounting. From massive energy use to vast quantities of water required to cool data centres, AI’s footprint is growing fast. So, in an age of water scarcity and climate crisis, can we justify this technological boom?

As The Conversation Weekly team ...

Scientists can get animals to do the strangest things. They’ve taught goldfish to drive cars, primates to perform calculations with Arabic numerals and giraffes to do statistical reasoning. But what’s the point?

In this episode, biologist Scarlett Howard from Monash University in Australia – who has taught bees to tell the difference between odd and even numbers – defends the importance of these seeming...

Countries around the world are meeting in Geneva in August to negotiate a global plastics treaty aimed at curbing plastic pollution. The last round of negotiations failed last November after oil-producing countries refused to sign up to a clause calling for the world to reduce its production of plastics.  

But how did the world become hooked on plastic in the first place? This week, we're re-running an episode we first air...

Donald Trump is suing Rupert Murdoch, alongside the Wall Street Journal and Dow Jones and others, for libel after the Journal published an article alleging that Trump once wrote a “bawdy” birthday letter to the convicted sex offender, the late Jeffrey Epstein. Trump is seeking US$10 billion in damages.

Trump and Murdoch have a transactional friendship that goes back decades. Despite past tensions, this rupture is somethin...

Israel has never officially confirmed or denied having nuclear weapons and has never signed the nuclear non-proliferation treaty. Instead, even as evidence has emerged about its nuclear capabilities, Israel has maintained a policy of nuclear ambiguity.

The origins of this opacity lie in a secret deal forged in a one-on-one meeting between Israeli prime minister, Golda Meir, and the US president, Richard Nixon, at the ...

The majority of the world’s rechargeable batteries are now made using lithium-ion. Most rely on a combination of different rare earth metals such as cobalt or nickel for their electrodes. But around the world, teams of researchers are looking for alternative – and more sustainable – materials to build the batteries of the future.

In this episode, we speak to four battery experts who are testing a variety of potential battery materia...

 Across Europe, far-right movements are gaining ground. By normalising nationalist rhetoric and challenging democratic institutions, these parties raise comparisons with former periods of fascism on the continent. Between 1943 and 1945, when Nazi forces occupied northern Italy, ordinary people in towns and villages across the country took up arms against fascism in one of Europe’s largest resistance movements. Now, 80 years later, ...

The language from European leaders was fawning and obsequious. At one point, the head of Nato, Mark Rutte, even called Donald Trump “daddy”. But when the US president left the Nato summit in late June, there was a sigh of relief that he had not made any more angry criticism of the alliance.

And after months of American pressure, Nato members agreed to increase their spending on defence to 5% of GDP by 2035.

 So how did Europe becom...

Robert F Kennedy Jr caused controversy in April by promising to find a cause for autism by September. Claims by the new US secretary for health and human services that autism is a “preventable disease” with an environmental cause,  contradict a body of research that suggests autism is caused by a combination of genetic and external factors.

The US government announced that to support its new research effort into autism it would buil...

Faced with the choice in their daily lives, their work or their politics, why do some people decide to keep quiet, to censor themselves in anticipatory obedience, even if they’re not ordered to do so?

In this episode we talk to self-censorship expert Daniel Bar-Tal at Tel Aviv University about what drives people to censor themselves, and its consequences for society.

This episode was written and produced by Katie Flood with assistan...

As Jaws marks its 50th anniversary, sharks continue to get a bad rap. Film after film portrays them as terrifying hunters, the bane of surfers and swimmers. But in Indonesia, sharks are the hunted. It’s the world’s largest shark-fishing nation, with more species of sharks found in Indonesian waters than in any other country.

So Indonesia was the ideal place for conservation scientist Hollie Booth at the University of Oxford to test ...

In October 2021, 136 countries agreed to establish new tax rules requiring large multinational companies to pay at least 15% in corporate tax. Nearly four years later, this ambitious agreement is finally being implemented around the world, but its success faces big challenges.

In the second part of The 15% solution, we examine progress towards implementing the Organisation for Economic Cooperation and Development's global tax framew...

For decades, multinational corporations have used sophisticated strategies to shift profits away from where they do business. As a result, countries around the world lose an estimated US$500 billion annually in unpaid taxes, with developing nations hit particularly hard.

In the first episode of The 15% solution, we explore how companies have exploited loopholes in the global tax system. We speak to Annette Alstadsæter, director of t...
