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 administration’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 support medical research both in the U.S. and around the world, nearly 800 grants have been terminated. The administration 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 administration.

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.
