    In Dedication: Richard Scolyer on Risk, Hope and Radical Cancer Treatment (483)

    This conversation was originally recorded and published in November, 2024. In light of Richard's passing, we wanted to share it again because his insights remain as inspiring and relevant as ever. We extend our deepest condolences to his family, friends and colleagues.

    Beasts Behaving Badly with Dr. Ann Jones (482)

    Dr. Ann Jones joins me to chat about her hilarious new What the Duck? series, Nature's Most Wanted, which dives into the wild world of criminal animals. We investigate some of nature's strangest case files… a duck caught speeding (twice), drug-addicted parrots, an underwear-nicking cat, drunk elephants, and heavyweight hamsters! A funny look at the surprising ways animals collide with the human rules we've created. What The Duck?! Nature's Most Wanted

    Seaweed! The Humble Organism Fighting Climate Change with Assoc. Prof. Alex Campbell (481)

    Marine Ecologist Assoc. Professor Alex Campbell takes us into the wonderful, under-appreciated world of seaweed and makes the case that it might be one of our most powerful allies against climate change! We dive into seaweed's evolutionary history and the troubling decline now underway: as ocean temperatures rise, marine organisms are shifting toward the poles at a rate of over 60km per decade to escape the heat, with Tasmania's once-thriving giant kelp forests shrinking by a staggering 90% since the 1990s due to devastating changes to their habitat.
 But the story isn't all bad news. Seaweed also holds genuine promise as a climate solution - from carbon sequestration and biofuel production, to a renewable alternative to plastic, to livestock feed additives that can dramatically cut methane emissions. Alex makes a compelling case for why this humble marine organisms deserves a much bigger role in how we tackle climate change.

    Why Weight Loss Drugs Don't Work On Their Own Dr. Nick Fuller (480)

    I'm joined by Dr Nick Fuller to dissect the long-term effectiveness of weight loss medications and why lasting results do actually require more than medication alone. Nick explains why evidence-based behavioural weight management programs remain the first-line approach to weight loss built on three key pillars: diet, exercise and sleep (did you even know that sleep plays a big role in regulating hunger hormones?!) Drawing on his team's research, Nick shares why many people regain weight after stopping medication and why behavioural change is essential for sustainable success (and keeping weight off for good!)

    Inside Microsoft's Global Research Lab With Dr. Peter Lee (479)

    This episode I'm joined by Dr Peter Lee, Head of Research at Microsoft, to explore the ideas shaping the future of technology. Leading 14 research laboratories globally and overseeing a research and development program that receives more than 10% of Microsoft's overall budget, Dr Lee shares his journey to the top of one of the world's largest innovation engines. From AI tools transforming early cancer detection and predicting protein structures in hours (instead of years!), to discovering new battery materials and improving weather forecasting through deep learning, the conversation reveals how research is moving from possibility to real-world impact. We also explore Microsoft's investment in open-ended innovation, research not driven by immediate products, but by imagining entirely new experiences and technologies.

    The (Not So) Boring Billion with Prof. Dietmar Müller (478)

    In this episode, we speak with Dietmar Müller about the "Boring Billion", a seemingly quiet period in Earth's deep history that may have been crucial for the evolution of complex life. Drawing on his latest research, Müller explains how plate tectonics, passive continental margins, and volcanic outgassing shaped Earth's slow carbon cycle and gradually oxygenated the oceans during the mid-Proterozoic era. Müller also reflects on how young the science of plate tectonics really is, and discusses the open-source EarthByte tools his team at the University of Sydney has developed to model Earth's ancient geological past. www.earthbyte.org/

    Solving a Cosmic Radio Signal Mystery with Kovi Rose (477)

    Astronomer and soon-to-be Dr. Kovi Rose joins us to discuss his newly published Nature Astronomy paper on one of the universe's newest mysteries: strange repeating flashes of radio waves and X-rays coming form deep within our galaxy! His team's discovery of ASKAP J174 has helped identify the source as a pair of stars orbiting each other, with a white dwarf pulling or accreting material from its companion. This discovery could help unlock the origins of mysterious signals flashing across the sky, unlocking even more secrets of the universe.

    Coffee & Blood Pressure Explained with Prof. Clare Collins (476)

    Professor Clare Collins returns to the pod to answer a common question: does coffee raise your blood pressure? We also discuss how genetics influence whether you're a fast or slow caffeine metaboliser, the beneficial phytonutrients found in coffee, why decaf still has health benefits, and when people with high blood pressure may need to be more cautious with their intake. nomoneynotime.com.au
