The legacy of Jane Goodall —from chimp whisperer to changing how science understands primates
Jane Goodall’s radical ideas that animals have individual personalities, relationships and even emotions reshaped how we understand primates. It also sparked fierce ethical debates that are still playing out today: Do great apes have rights? What responsibilities do researchers carry when studying minds so much like our own? Jan Goodall wasn't just a trailblazing scientist. She became one of the most influential conservationists of the last century and created the foundation of modern primatolog

The future of ageing — what will growing old be like in 2076?
Australia's population is getting older. In fact, by 2076, 45 per cent of us - that's 18 million people - will be aged over 65. What will ageing look like in 50 years time? Will science keep us healthier for longer? What role will older people play in the workforce, in the economy, and in our communities? Will robots wipe our bottoms, or keep us company? How will we respond to major health challenges—like dementia, already our leading cause of death— and the growing burden of chronic disease? Th

It's an ancient Hindu poem, so why does The Ramayana still resonate?
It's been called "The Odyssey of the East", and the ancient Hindu poem remains central to Asian cultures and traditions from India to Indonesia 2500 years after it was written. From the names of Thai kings, to traditional Javanese shadow puppets, the ancient temples of Cambodia's Angkor Wat to contemporary Indian politics, the journeys of Rama and his wife Sita are deeply embedded. Why does this story endure? The conversation The Ramayana reimagined: storytelling across cultures was recorded at

When you trust social media influencers more than your GP — what can only go wrong?
From doctors spruiking untested therapies to celebrities selling "revolutionary wellness hacks", self-styled health gurus promise results traditional medicine can't. Social media transforms a healthcare system that struggles with GP wait times and short face-to-face appointments. Because when it comes to trust, it turns out fame competes surprisingly well with scientific evidence. Bad Influence: How the internet hijacked our health was recorded at the York Festival of Ideas.

Why Diego Bonetto wants you to eat weeds
Foraging and eating wild food is nothing new in Australia. First Nations people have done it for over 50,000 years. Even your grandparents often still used to search for eatable weeds, mushrooms and nuts at the edge of their fields and in the woods. This knowledge is lost today. But attitudes to weeds have also changed. We don’t see weeds as a valuable resource anymore, only as a pest to get rid of. Is it time to change that and to rediscover the traditional knowledge of foraging? And what would
