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.
