In part two, Associate Professor Marian-Andrei Rizoiu from the University of Technology Sydney explains how misinformation and toxic online cultures spread. We dive into the "manosphere pipeline" targeting boys as young as 10, its real-world impacts on schools and families, and how it can escalate into radicalisation. Rizoiu outlines his team's six-stage pipeline - from passive curiosity to active involvement - and why simply giving people facts doesn't solve the problem. Instead, this is a human challenge, and his lab is exploring new ways to diffuse and counter online misinformation before it turns dangerous. Linkedin: Marian-Andrei Rizoiu

Most of us throw our clothes in the wash without a second thought, but what if that habit is doing more harm than good? In this episode, Dr. Holly Kaye-Smith, social change expert and communications specialist, challenges the way we think about cleanliness, climate action, and everyday laundry. From surprising stats (over 90% of washed clothes aren't even dirty!) to the hidden environmental cost of every wash cycle, we dive into the myths, microplastics, and mindsets that shape our laundering routines. Holly shares practical refreshing techniques that save water, and why she recommends everyone have a "rewear chair."

In this episode, we speak with Dr. Andy Reisinger, an internationally recognised expert in climate change science and policy, with a focus on mitigation and agricultural emissions. Together, we unpack the concept of climate overshoot - why the world is set to exceed the 1.5°C warming limit within the next five years, and what that means for people and the planet. Dr. Reisinger explores whether the damage already done is reversible, what it would take to get back on track, and, hypothetically, the bold actions he would take if he had the power to drive real societal change to combat climate change.

Consumer technology expert Ashley Iredale returns for part two, bringing more surprising facts about everyday household appliances. We break down why your fridge actually contains more heaters than coolers, demystify the Energy Star rating system, and settle the debate on whether front-loading or top-loading washers are more efficient at cleaning clothes.

This episode i'm joined by Ashley Iredale, a consumer technologist and content producer whose winding career through industrial design has armed him with a trove of quirky tips and practical wisdom. Ashley breaks down the real efficiency of hand-washing versus dishwashers, explains how a dishwasher can double as an oven, and settles the age-old question of how toilet paper should hang. We also dig into his non-linear career journey and how it led to his deep well of surprising insights. There was so much to cover that Part Two lands next week! Linkedin: Ashley Iredale
