One hundred years ago, a paper was published in the journal Nature that would radically shift our understandings of the origins of humanity. It described a fossil, found in a lime mine in Taung in South Africa, which became known as the Taung child skull. The paper’s author, an Australian-born anatomist called Raymond Dart, argued that the fossil was a new species of hominin called Australopithecu...

As the Trump administration ratchets up its threat to slap tariffs on allies and economic rivals alike, the world is bracing for another wave of costly economic disruption. This protectionist shift is all the more remarkable given how the US championed trade liberalisation for decades. So what does it actually take for a country to use protectionism to grow its economy? Some developing countries h...

Since Elon Musk's acquisition of Twitter in 2022, many users have looked for alternatives, fuelling a wave of online migration from the social media platform.

In this episode, we speak to Robert Gehl , Ontario Research Chair of Digital Governance at...

As Germany heads towards elections on February 23, the far-right Alternative for Germany (AFD) is polling in second place on 20% of the national vote. The AFD's roots are in nationalistic and racist movements. It continues to take an ultra anti-immigration stance and is calling for "demigration" – effectively the deportation of migrants.  In this episode, Rolf Frankenberger, an expert on righ...

Quantum computers have the potential to solve big scientific problems that are beyond the reach of today’s most powerful supercomputers, such as discovering new antibiotics or developing new materials. But to achieve these breakthroughs, quantum computers will need to perform better than today’s best classical computers at solving real-world problems. And they’re not quite there yet. So what is st...

Firefighters in Los Angeles continue to battle devastating wildfires that have killed at least 27 people and left thousands of homes destroyed.

The interview originall...

From Gaza to Ukraine, today’s war zones are being used as testing grounds for new systems driven by artificial intelligence. Billions of dollars are now being pumped into AI weapons technology, much of it from Silicon Valley venture capitalists. In this episode, we speak to Elke Schwarz , a reader in political theory at Queen Mary University of London in the UK who studies the ethics of autonomous...

Every year, 400 million tons of plastic are produced worldwide, and every year, approximately 57 million tons of plastic waste is created. And yet in November, the latest round of negotiations to agree the first legally binding international treaty on plastics pollution collapsed. So what can we really do about the plastics pollution problem? In this episode we sat down with Mark Miodowonik , prof...

In this episode, we speak to two experts on the death penalty, Carolyn Hoyle and Parvais Jabbar from the University of...

Surveys suggest that in many western democracies, political trust is at rock bottom. But is it really such a bad thing for people living in a democracy to distrust their government? In this episode, we talk to political scientist Grant Duncan , visiting scholar in politics at City St George's, University of London, about why he thinks a certain level of distrust and scepticism of powerful pol...

An orca that pulled along the corpse of its baby for 17 days. An opposum that plays dead to fool predators. And a chimpanzee that cleaned the teeth of its dead baby. Observations of behaviours like these suggest animals have a complex relationship with death. In this week’s episode, we speak to Susana Monsó , an associate professor of philosophy at the National Distance Education University in Mad...

The online retail giant Amazon is known for its resistance to unions. In this week’s episode, we tell the story of what happened at one warehouse in Coventry in the UK when its workers tried to gain official recognition for the GMB union, one of the country’s biggest labour unions. We talk to Tom Vickers , a sociologist at Nottingham Trent University in the UK, who spent weeks observing workers’ e...

It's been 50 years since the American paleoanthropologist Donald Johanson discovered the fossil of ancient hominin 'Lucy' in the Afar region of Ethiopia. The find took the story of human evolution back beyond 3 million years for the first time. Yet, despite largely centring on the African continent as the "cradle of mankind", the narrative of hominin fossil discovery is striking for its lack of Af...

For generations, cod fishing was a way of life in Newfoundland and Labrador, the easternmost province in Canada. But in 1992, after cod stocks in the north Atlantic plummeted, the federal government imposed a moratorium on cod fishing. It was to last for 32 years until June 2024, when the government lifted the ban in a controversial decision. In this episode we speak to Tyler Eddy , a research sci...

Take a walk along a beach in parts of South Australia, and you may come across unusual patches of pink sand.
