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 out a new idea: would paying fishermen to release any sharks and rays caught accidentally in their nets help to keep more alive? Listen to Booth and her colleague M. Said Ramdlan in Indonesia discuss the unintended consequences of the incentive programme.

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 framework. Featuring Martin Hearson, a research fellow at the Institute of Development Studies in the UK. This episode of The Conversation Weekly was written and produced by Mend Mariwany.

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 the Centre for Tax Research at the Norwegian University of Life Sciences, and Tarcisio Diniz Magalhaes, a professor of tax law at the University of Antwerp in Belgium. In 2021, after years of international negotiations, the Organisation for Economic Co-operation and Development unveiled a global tax deal designed to address tax avoidance through a minimum corporate tax rate of 15%. But will this new framework actually work? And what happens when major economies refuse to participate? The 15% solution explores why a new global tax regime is needed, whether it can fix a broken system, and what’s at stake if it fails.

More than two thirds of guns recovered at Mexican crime scenes originate in the U.S. For decades, Mexico has struggled with staggering levels of gun violence fuelled in large part by weapons trafficked across its northern border. Now an investigation published by The Conversation has arrived at a new estimate of the scale of this illicit gun trade between the U.S. and Mexico in 2022: 135,000 guns. Investigative journalist Sean Campbell and Topher McDougal, a professor of economic development at the University of San Diego, spent a year combing through multiple databases and court documents and conducting interviews to understand how the flow of guns works. Their investigation reveals where in the U.S. the guns are coming from, what impact these American guns are having in Mexico, and how difficult it is for American law enforcement agencies to prosecute those trafficking guns across the border.

For much of the 21st century, one theory has dominated research efforts to cure Alzheimer's disease: the amyloid hypothesis. Beta-amyloid is a protein that builds up in clumps, or plaques, in the brains of people with Alzheimer's disease and is linked to their cognitive decline. But in recent years, despite the emergence of a couple of new drugs targeting these plaques, some scientists have begun to doubt the amyloid hypothesis. Donald Weaver, a professor of chemistry at the University of Toronto in Canada, is one of them. Weaver no longer believes there will be one magic bullet found to cure Alzheimer’s disease. Instead, he advocates for a magic shotgun approach that is likely to involve multiple ways of treating the problem, including starting much earlier in a person’s life. He tells us about shifts in the understanding of Alzheimer's during his career of more than 30 years, and the theories now emerging about what might cause the disease and how to treat it.

Liverpool FC just won the English Premier League. Contributing to their 5-1 victory over Tottenham to seal the title was Mohamed Salah, the Egyptian superstar who is the league's top scorer in the 2024-5 season. We're revisiting an episode that we first ran in December 2022 about research which used Salah to demonstrate how a celebrity footballer who is openly Muslim can help to reduce Islamophobia. Salma Mousa, now an assistant professor of political science at UCLA in the US, talks to us about her research. This episode was produced and written by Gemma Ware, with sound design by Eloise Stevens. Our other producers are Mend Mariwany and Katie Flood. Our theme music is by Neeta Sarl. More details can be found in an article that accompanied the original episode.

The Trump istration’s cuts to funding for American universities and research have left many scientists reeling and very worried. At the National Institutes of Health, which has an annual budget of US$47 billion to medical research both in the U.S. and around the world, nearly 800 grants have been terminated. The istration is considering cutting the overall budget of the NIH by 40%. In this episode, we speak to three scientists, Brady West and Sunghee Lee from the University of Michigan in the US, and Glenda Gray, an expert in HIV vaccines from the University of Witwatersrand in South Africa, about what it’s like to have funding cut by the Trump istration.

Few places on earth are immune to the explosion of anti-vaccination conspiracy theories and health disinformation fuelled by the COVID pandemic. But in countries like Brazil, where the disinformation flowed from the very top of government, the problem is even more acute and some people are exploiting the fear of others to make money. In this episode we speak to Ergon Cugler at the Brazilian Institute of Information on Science and Technology about his new research into how peddlers of disinformation on social media also sell fake cures and vaccine detoxes. And we ask disinformation researcher Igor Sacramento at Brazil's Oswaldo Cruz Foundation why some people are looking for solutions to their health problems in these dangerous chemicals and unproven protocols.

The Birkin bag made by French luxury retailer Hermès has become a status symbol for the global elite. Notoriously difficult to obtain, the world's rich obsess over how to get their hands on one. But when US retailer Walmart recently launched a much cheaper bag that looked very similar to the Birkin, nicknamed a "Wirkin" by others, it sparked discussions about wealth disparity and the ethics of conspicuous consumption. In this episode we speak to two sociologists, Parul Bhandari from the University of Cambridge in the UK and Aarushi Bhandari from Davidson College in the US, about the Birkin and what it symbolises.

Some of the leading brains behind generative AI have warned about the risk of artificial superintelligence wiping out humanity, if left unchecked. But what if the influence of AI on humans is much more mundane, influencing our evolution over thousands of years through natural selection? In this episode we talk to evolutionary biologist Rob Brooks about what AI could do to the evolution of humanity, from smaller brains to fewer friends.

Five years since Covid, not only has the pandemic affected the way we live and work, it’s also influencing the way researchers are thinking about the past. In this episode archaeologist Alex Bentley from the University of Tennessee explains how the pandemic sparked new research into how disease may have affected ancient civilisations, and the clues this offers about a change in the way humans designed their villages and cities 8,000 years ago.

Ships transport around 80% of the world’s cargo. From your food, to your car to your phone, chances are it got to you by sea. The vast majority of the world’s container ships burn fossil fuels, which is why 3% of global emissions come from shipping – slightly more than the 2.5% of emissions from aviation. The race is on to reduce these emissions, and quickly, to meet the Paris agreement targets. In this episode we find out what technologies are available to shipping companies to reduce their carbon emissions – from sails, to alternative fuels or a 'Google maps for the ocean'. Featuring Daniel Precioso, post-doctoral researcher at IE University in Spain and Alice Larkin, Professor of Climate Science and Energy Policy, University of Manchester.

For over 40 years, the Kurdistan Workers Party, the PKK, has waged an armed insurgency against Turkey, fighting for Kurdish rights and autonomy. But in late February, Abdullah Öcalan, the PKK’s imprisoned founder, called for the group to lay down its arms and dissolve itself. Days later, the PKK, which is labelled as a terrorist organisation by Turkey, Europe and the US, declared a ceasefire with Turkey. In this episode, we speak to political scientist Pinar Dinc at Lund University in Sweden about what’s led to this moment and whether it could be the beginning of a lasting peace between Turkey and the Kurds.

When the first cases of COVID-19 began to spread around the world in early 2020, people in Iquitos, a remote city in the heart of the Peruvian Amazon, weren’t unduly worried. They assumed their isolation would protect them. It didn’t. Peru, and Iquitos, were hit fast, and hard. In a surreal situation, people were left to fend for themselves, fighting to get hold of oxygen on the black market for their loved ones and forced to put themselves in danger to survive. In this episode we speak to researcher Japhy Wilson from Bangor University in Wales who spent a year living in Iquitos, trying to understand what happened there during the pandemic.

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 Australopithecus africanus. It was the first evidence that humanity originated in Africa. In this episode, we talk to science historian Christa Kuljian about Dart’s complicated legacy and to paleoanthropologist Dipuo Kgotleng about what’s happened to the city of Taung itself, and how paleoanthropology has changed over the last century.

As the Trump istration 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 have successfully used tariffs to do so, while others have struggled. In this episode, we talk to Jostein Hauge, a development economist at the University of Cambridge in the UK, about who wins and who loses from tariffs and protectionism.
