The Human Side of Misinformation Part 2 with Assoc. Prof. Marian-Andrei Rizoiu (445) [REPEAT]
Shirtloads of Science
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...

Rethinking Laundry for the Planet With Dr Holly Kaye Smith (430) [REPEAT]
Shirtloads of Science
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...

Climate Overshoot: The World Beyond 1.5 Degrees with Dr. Andy Reisinger (458)
Shirtloads of Science
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...

The Discovery That Changed Astrophysics with Prof. Dame Jocelyn Bell Burnell (455)
Shirtloads of Science
In this episode, I’m joined by the legendary Dame Susan Jocelyn Bell Burnell - the pioneering astrophysicist who discovered pulsars, launching an entirely new field of astrophysics. She began her PhD searching for quasars, but soon noticed a strange, repetitive signal appearing night after night - so peculiar she jokingly labelled it LGM ("Little Green Men”). That signal would become one of the most important astronomical discoveries of the century, though the credit and Nobel Prize were controversially awarded to her supervisor. Dr Bell Burnell also shares why she donated $4.3 million...

Sunscreen Safety in Australia with John Staton (454)
Shirtloads of Science
This week I'm joined by John Staton, one of Australia's leading sunscreen-testing experts, to unpack the big headlines surrounding sunscreen safety. A recent Choice report revealed that 16 out of the 20 tested sunscreen products failed to meet their advertised SPF rating by a significant figure. John helps us to understand what is really going on. He breaks down how sunscreens actually work and the science behind SPF testing and why so many products fell short.

What are Time Crystals? with Prof. Geraint Lewis (453)
Shirtloads of Science
In this episode, friend of the show and astrophysicist Professor Geraint Lewis returns to help me wrap my head around one of the strangest ideas in modern physics: Time Crystals. After stumbling across a Nature article that left my brain pleasantly scrambled, I called up Geraint for a deep-dive into what time crystals are and why physicists are so excited about them. We explore why Time Crystals don’t have real-world applications yet, but how they could open entirely new frontiers in future technology.
