  • The Wellness Woo Economy with Kate Thomas (466)
    Mar 21 2026

    Pharmacist and science communicator Kate Thomas shares how a viral debunking video launched her into the world of online health education. In this episode, we explore the booming "wellness woo" economy and sift through the weeds on why misleading short-form content spreads so easily and the risks of unregulated wellness influencers. Kate breaks down the truth about supplements, the power of placebo, and why accessible, personalised health advice is so hard to find online. She also highlights the important role pharmacists play in helping consumers make informed choices.

  • The Hidden Health Impact of Microplastics with Prof. Michaela Lucas (465)
    Mar 14 2026

    ***Prof Lucas would like to provide the following clarification in regards to comments relating to prenatal BPA exposure and male autism spectrum disorder: "A positive association between high prenatal BPA exposure and ASD diagnosis was only seen in male offspring with a genetic predisposition to low aromatase enzyme activity."

    Professor Michaela Lucas, an Immunologist and Immunopathologist researching the health impacts of plastics, joins me to explore what microplastics and plastic-associated chemicals may be doing inside our bodies. We discuss how compounds like bisphenols and phthalates can act like hormone-mimicking molecules, the evidence linking plastic exposure to developmental and fertility concerns, and why some estimates of microplastics in the body may have been overstated.

    Professor Lucas also shares insights from her ongoing study in Perth examining how everyday exposures, particularly ultra-processed foods packaged in plastic, may contribute to microplastics in the body. Listeners can subscribe to receive the study results when they're released via www.uwa.edu.au/projects/the-perth-trial.

  • Deepfakes Online and The Future of Truth with Dr. Anna Broinowski (464)
    Mar 8 2026

    I'm joined by Dr. Anna Broinowski - Senior Lecturer and Director of the Master of Film and Screen Arts at Sydney College of the Arts, University of Sydney - to unpack the rise of deepfakes and synthetic media.

    We discuss the emergence of deepfake pornography in 2017, the fact that around 90% of deepfake content targets women and girls, and the growing use of AI in propaganda. From political manipulation to fake ads impersonating me (!), this episode explores how deepfakes are eroding trust, and what that means for the future of media, filmmaking and truth more broadly.
