  • Fact-checking Trump’s autism announcement

    Fact-checking Trump’s autism announcement
    Sep 24 2025
    In a televised press conference on Monday, Donald Trump and health secretary Robert F Kennedy Jr made a series of unproven claims about autism and its links to paracetamol use in pregnant women, and childhood vaccinations. The comments were immediately refuted by scientists and health agencies around the world, but many expressed concern about the impact of this misinformation being repeated at the highest levels of government. So what does the science really say? Madeleine Finlay speaks to science editor Ian Sample to fact check the claims made in the announcement, and find out what decades of scientific research into autism tells us about its causes and why diagnoses are on the rise.

    Sep 18 2025
    The murder of political activist Charlie Kirk has prompted fears about rising levels of political violence in the US after a number of high-profile assassinations and attempted assassinations of political figures in recent years. But how connected are these events and do they signal a rise in public support for this kind of violence? To find out Ian Sample speaks to Sean Westwood, an associate professor in political science at Dartmouth College and director of the Polarization Research Lab. He explains how political violence has evolved and why overestimating the support for such acts can be dangerous. Help support our independent journalism at theguardian.com/sciencepod
