What if we could turn back time on our biological clock and slow down — even reverse — aging? High profile Harvard scientist David Sinclair is co-author of the New York Times bestseller Lifespan: Why We Age and Why We Don’t Have To. His lab’s work is as ambitious as it is controversial.  He wants to radically change the way we live our lives — and push at the boundary of what it means to be human. Professor Sinclair joins Big Ideas host Natasha Mitchell at the 2025 World Science Festival Brisbane.

It's been 60 years since then Australian Prime Minister Robert Menzies sent Australians to fight in the Vietnam War. Since that time, the defence force has been involved in many armed conflicts and peace keeping missions around the world — but with varying degrees of public support. So how have successive Australian governments managed public consensus around military engagements? And with war once again a threat to global security, might they have to do so again?

These events were recorded at the Robert Menzies Institute at the University of Melbourne on 29 April 2025, and at the Australian Catholic University on 11 April 2025.

If democracy is the will of the people, what does this federal election result say about Australia? In his election night victory speech, Prime Minister Anthony Albanese said Australians had voted for Australian values, claiming these were fairness, aspiration and opportunity for all. But is this right message we should take from the election result?

This conversation was recorded live at the 2025 Melbourne Writers Festival in partnership with The Wheeler Centre. To explore more Melbourne Writers Festival talks, visit mwf.com.au

Australians are now the biggest consumers per capita of clothes in the world. But just three per cent of clothing is made here in Australia. So is it time for a fashion rethink?

Meta's Mark Zuckerberg has said “a lot of the corporate world has become culturally neutered” and that it needs more “masculine energy”? Has it and does it? At Meta, he recently shut down initiatives that promote equity and diversity in his workplace. In the USA, so has Ford, Mcdonalds, Walmart, and the Trump administration. But in Australia, less than 5% of CEOs in private companies are women and the gender pay gap is slow to budge. Meanwhile, future male leaders are being courted online by manosphere influencers like Andrew Tate. Where is all this heading?  Join Natasha Mitchell and guests to consider the consequences for modern workplaces.

This event was produced by the 2025 Sorrento Writers Festival curated by festival director and founder Corrie Perkin.

Democracies in retreat, attacks on science, border disputes, death and destruction. It can feel like we are living in unprecedented times - but here's the thing: world history has a habit of repeating itself. So what lessons does history teach us about this moment in which we find ourselves? Do we humans learn anything from the past, or are we destined to repeat the same mistakes?

This event was recorded at Adelaide Writers' Week on 5 May 2025.

A story of continents crashing and cleaving apart, the making of a civilisation, the language of the dead, and ... a mummified rat makes a cameo too. The Incan empire was vast and sophisticated. It built the stunning citadel in the clouds of Machu Picchu in the Andes mountains. But within a century its people were catastrophically wiped out by the onslaught of the Spanish conquistadors. Join Big Ideas host Natasha Mitchell with two intrepid researchers — an archaeologist and a leading mammalogist — to hear what amazing discoveries continue to be made in Peru and South America.

Thanks to the Australian Museum for hosting and producing this event.

The language used to talk about mental ill-health can play a key role in reducing or enforcing stigma. And it's constantly evolving. But what terms should be used and when? And by whom? The wrong word can not only deeply hurt a person's feelings. It can end careers, destroy relationships, cut access to support systems. This special World Mental Health Day PsychTalks event was presented by the Mental Ill-Health Stigma Researchers Australia Network (MISRA), the Melbourne School of Psychological Sciences, and the Melbourne School of Global and Population Health, with the support of SANE’s StigmaWatch program.
