    40 years after Chernobyl we face a new nuclear risk — this time as a weapon of war

    23/04/2026 | 55 mins.
    The explosion of reactor number four at the Chernobyl Nuclear Power Plant is not only a story of the past. Right now, nuclear plants are weaponised in the Iran war. It happened in 2022 when Russian forces occupied the Chernobyl exclusion zone. A new way of weaponising nuclear power. What have we learned from the worst nuclear accident in history — and what have we failed to learn?
    This conversation was presented by the Royal Society of Arts (RSA) and the Ukrainian Institute London.

    Is Trump a new Nero, Caligula, Caesar? Can the Roman Empire help us make sense of today's chaos? And other burning questions

    22/04/2026 | 59 mins.
    Is President Trump a new Nero, or a contemporary Caligula? The Roman Empire was full of merchants of chaos, power-hungry emperors, epic wars, backstabbing, betrayals — the whole horror show. And it was a time of civilisational scale change. As we grapple with a rewriting of the world order,  does Ancient Rome have lessons for us today — about the building and breaking of empires, or the rise and fall of autocrats? Or are these sorts of comparisons with the past fraught with complication? 
    Join Natasha Mitchell and guests at this Melbourne Museum event to coincide with the opening of the ROME: Empire, Power, People exhibition.

    Australia's broken social contract — Tahlia Isaac wants to protect women in prison

    21/04/2026 | 54 mins.
    What happens to a community when it punishes its most vulnerable instead of protecting them Drawing on her own story of addiction, imprisonment, and recovery, as well as her frontline work supporting women behind bars and post-release, Tahlia Issac challenges the "tough on crime" narrative. The typical incarcerated woman in Australia is First Nations, a mother, a survivor of violence, and imprisoned for a low-level offence. Locking her up doesn't make communities safer — it makes them more fragile.
    This is the 2025 International Women's Day Address at the National Press Club of Australia.
