Nobel laureate Shimon Sakaguchi on his immune system breakthrough
Back in the 1980s, when Shimon Sakaguchi was a young researcher in immunology, he found it difficult to get his research funded. Now, his pioneering work which explains how our immune system knows when and what to attack, has won him a Nobel prize.Sakaguchi, along with American researchers Mary Brunkow and Fred Ramsdell, were jointly awarded the 2025 Nobel prize in physiology or medicine for the work on regulatory T-cells, known as T-regs for short, a special class of immune cells which prevent our immune system from attacking our own body.In this episode Sakaguchi tells The Conversation about his journey of discovery and the potential treatments it could unlock.This episode was produced by Mend Mariwany, Katie Flood and Gemma Ware.

The diagnosis dimension to the rise in autism
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 them, used by psychiatrists and psychologists around the world. In this episode, Andrew Whitehouse, a professor of autism research at the University of Western Australia, explains why this shift in autism diagnosis happened in the 1990s, what impact it had, and what it's meant for the support autistic people get.

Pressuring the Fed doesn't end well
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 – became a cautionary tale about what can happen if politicians threaten the independence of central banks.

Palestinian statehood: the route to recognition
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 liberation movement. Nassar then traces how we've got to the point where more than 150 countries will recognise an independent Palestinian state – a move that she believes is more of a symbolic gesture than a meaningful route to Palestinian sovereignty.This episode was written and produced by Mend Mariwany and Gemma Ware with assistance from Katie Flood.
