Roger Short (1930-2021) discusses influences in his early life, and some of his research achievements including melatonin as a controller of circadian rhythms, and aspects of reproductive biology across the animal world.

First they learnt how to flip open wheelie bin lids. Now they're using water fountains.Masters of the urban landscape, sulphur-crested cockatoos (Cacatua galerita) are more than capable of some quirky (and sometimes messy) antics.So what do these entertaining exploits tell us about cockie innovation — or even cockie culture?

Get ready for gravitons, dark photons and transition states. Kathryn Zurek takes us on a tour of the bewildering world of quantum physics.

A couple of months ago, a killer started mobilising off the South Australian shore — one that would wipe out marine life, make surfers feel sick, and smother picturesque beaches in thick foam.The culprit? A bloom of tiny organisms called microalgae. We can't see them with the naked eye, but in big enough numbers, they can devastate ecosystems.So what made the South Australian algal bloom so lethal, and can anything be done about blooms like it?

People have been in the Australian wilderness for generations. But can people be considered part of the natural landscape or will they always have an impact?

Daswin De Silva, a Professor of AI and Analytics at La Trobe University, dives deep into the revolutionary concept of Artificial General Intelligence (AGI). He discusses how AGI could outperform humans across various tasks, raising questions about its potential to solve global issues like climate change. Daswin emphasizes the significance of regulatory frameworks as the technology evolves and explores the fine line between the benefits and risks of AGI's rapid development. Will it save us or challenge our very existence?

Sharon Carlton, a dedicated science communicator, and Ariane Rod, a brilliant science historian, dive into the life of Mary Somerville, a remarkable 19th-century scientist. They unveil her inspiring journey from limited education to correcting Newton's work and aiding in the discovery of Neptune. The discussion highlights the challenges faced by pioneering women in math and science and how Somerville’s groundbreaking contributions have persevered through time. They also explore the evolution of light theory and Mary’s enduring legacy as a trailblazer for future generations.

Bruce Warrington, CEO and Chief Metrologist of the National Measurement Institute, dives into the fascinating world of measurement. He discusses the historical significance of the Treaty of the Metre, which unified global measurement standards. Listeners will learn how the metric system emerged during the French Revolution and the challenges in defining the metre. Warrington explains the shift from physical lengths to atomic precision and underscores the crucial role accurate measurements play in everything from manufacturing to everyday life.

Amateur fossil hunters make a major discovery. And Marilyn Renfree describes the sophisticated reproduction of marsupials.

Southern right whales (Eubalaena australis) were named by whalers because their high oil content made them the "right" ones to kill.In the decades since whaling was banned, southern right numbers increased — but a new study shows that population growth stalled, and might've dropped a bit, despite current numbers still far below what they were in pre-whaling times.So what's going on with the southern rights?
