The Beatles shook the world to its core in the 1960's and, to this day, new generations continue to fall in love with their songs and their story. At the heart of this phenomenon lies the dynamic between John Lennon and Paul McCartney. Few other musical partnerships have been rooted in such a deep, intense and complicated personal relationship. Ian Leslie uses the songs they wrote to trace the shared journey of these two compelling men before, during, and after The Beatles.This talk is provided by the York Festival of Ideas.

A frank and impassioned plea for peace by Gareth Evans. As Australia's former Foreign Minister and former president of the International Crisis Group, he's spent most of his career forging real paths to peace globally. From Sudan to Gaza, Myanmar to Ukraine - who can we rely on to stop "forever" wars and genocides? Does Australia have a unique role to play? And what about the UN in its 80th year?

Primatologist Jane Goodall once said: "It actually doesn't take much to be a difficult woman. That's why there are so many of us." She spoke up. For all the species who go unheard, or unnoticed by humans. She was a giant in the global environmental movement. She first walked into the wild forests of Tanzania as a young woman with no science training and embarked on what is now the longest-running study of chimpanzees in their natural habitat. Her trailblazing fieldwork changed our understanding of other primates and the threat we pose to their continuing existence. It changed her. And it changed the world. At 91, she was still travelling the world right up until her last breath, to help give all other species theirs. She was deeply compassionate, and her campaigns deeply connected with people. Dr Jane Goodall joined Big Ideas host Natasha Mitchell to discuss hope in action the 2022 WOMADelaide Festival. This conversation was originally broadcast on ABC Radio National's Science Friction in May 2022.GuestDr Jane GoodallPrimatologist, environmentalist, naturalistFounder, Jane Goodall InstituteFurther info:The Book of Hope: A survival guide for an endangered planetJane Goodall and Douglas Abrams (Penguin, 2021)Jane Goodall Institute AustraliaRoots and Shoots AustraliaThe Jane Goodall HopecastThanks to the 2022 WOMADelaide Festival.

Former US secretary of state Condoleezza Rice assesses the break-up of globalisation and the world order. The way in which countries such as the United States or Germany focus on sovereign goals is part of the problem. And that's likely not to stop any time soon.

Join Big Ideas host Natasha Mitchell with three women embracing the radical practice of finding joy in big bodies. Fat bodies are often stigmatised, stereotyped, shamed, medicalised, and politicised. Even the word F.A.T gets denigrated. But there is another way. Reckoning with eating disorders and society's limitations, Dani, Evie, and Kalpana are no longer holding back from the delights of food, fashion, dance, ocean swimming, and more. Hear why, for them, the personal is political. But can expectations to be fat and jolly become a burden too? What about the radical act of just being and big?This event was hosted and organised by the inaugural Fat Joy Festival and the 11th International Weight Stigma ConferenceSpeakersDani Galvin (aka Dani Adriana)Content creator and body positivity and mental health advocateFat peer support facilitatorCo-creator, plus-size pop-culture inspired costumes and accessoriesBachelor of Counselling graduateEvie (Evangeline) GardenerPublic health researcher and advocatePhD studentUniversity of QueenslandKalpana PrasadPerformer, facilitator, choreographer with Bring a Plate Dance companyPostgraduate speech pathology studentDisability support workerThanks to Dr Lily O'Hara from Griffith University, the convenor of the Fat Joy Festival and the 11th International Weight Stigma Conference.Further reading and viewingHow we think about obesity and body weight is changing, here's why (article co-athored by Evie Gardener)The Real Cost of Appearance Ideals and Discrimination report (The Butterfly Foundation)Fat Joy PodcastThe body is not an apology by Sonya Renee TaylorWhat we talk about when we talk about FAT by Aubrey GordonYou have the right to remain fat by Virgie Tovar"Fat" isn't a bad word — it's just a way I describe my body by Aubrey Gordon Selling Stigma: Afflictive Power and Fat Oppression - presentation by Rachel Fox

Meet apes that swallow leaves to dislodge worms and sparrows that use cigarette butts to repel parasites. Many animals use medicine to treat themselves — something that for a long time has been thought to be the exclusive domain of humans. Now scientists are turning to the medical knowledge of the animal kingdom to improve agriculture, create better lives for our pets, and develop new pharmaceutical drugs.Presented at the Free Library of PhiladelphiaListen to Big Ideas: SpeakerJaap de RoodeSamuel Candler Dobbs Professor of Biology at Emory UniversityAuthor of Doctors by Nature: How Ants, Apes, and Other Animals Heal Themselves

At face value, collaboration sounds like a good thing: collaboration in the classroom, with colleagues, or between nations. But throughout history, collaboration was not always considered a virtuous act, and those who were identified as collaborators were shunned, humiliated or worse. This talk explores how people justify their involvement in wrongdoing, and how when collaboration devolves into conformity, it risks silencing dissent.This event was recorded at the Bundanon Art Museum.SpeakerDr Simon Longstaff — Executive Director, The Ethics Centre

Citizen Jury is ABC Radio National's experiment in citizen-led democracy. The ingredients? A gnarly issue + a jury of citizens = conversations + ideas for solutions + a public event to share them.
