This week we're joined by Gerry Griffin, an aeronautical engineer and Apollo flight director who worked on every single moon landing during the Apollo mission, from Apollo 11 to Apollo 17. In this chat, he shares how the Mission Control team worked to manage each mission, second by second, in rotating shifts. With far more data on the ground than on board, Mission Control was better positioned to help the astronauts solve problems as they arose.
Gerry walks through some of the "showstopper" moments that could have ended in disaster, including the lightning strike on Apollo 12 and the 1202 alarm during the Apollo 11 landing. He also talks about Apollo 13, where an oxygen tank failure led to the famous call, "Houston, we've had a problem." Gerry's firsthand experience of that mission led to his role as an advisor on the film Apollo 13.
Gerry is coming to Australia next year for a series of events called SPACELIVE. Visit the website for more details https://www.spaceliveofficial.com/

When Robbie Williams announced he had been diagnosed with scurvy earlier this year, Professor Clare Collins was relieved… why?! Because he was bringing attention to a major issue arising from the use of the popular class of weight loss medications, GLP-1s. Professor Collins joins me on Shirtloads to discuss how nutrient deficiencies have increased among those using these medications.
Clare agrees that GLP-1 medications DO have an overall net positive effect as effective and beneficial medications, but warns that without proper nutrient intake (due to a suppression in appetite) nutrient deficiencies are much more common than they should be. This is an aspect of the GLP-1 discourse that does not get enough attention - particularly when discussing adverse side effects. Visit No Money, No Time to read the article www.nomoneynotime.com.au/

Science writer and journalist Marcus Chown returns for a shorter, more philosophical chat. When Einstein first proposed gravitational waves, atoms hadn't even been discovered, so who knows what the next century holds? We dig into the strange idea of the universe's "mathematical twin," and discuss the Standard Model of physics - a brilliant framework, but riddled with holes.

Science writer and former astrophysicist Marcus Chown joins us to discuss the elusive graviton - the theoretical particle behind gravity. In this chat we dig into the four fundamental forces of nature, why gravity is so uniquely hard to pin down, and why detecting a graviton would require a detector larger than Jupiter. Marcus also unpacks string theory, the only framework that manages to fold gravity in with the other forces, and why it's fallen out of favour with much of the physics community.

What if evolution isn't just about the survival of the fittest? Rowan Hooper, senior editor at New Scientist, joins Shirtloads to discuss his new book Togetherness - a challenge to the idea that nature is defined purely by competition. From the fig and wasp's ancient partnership to the mycorrhizal fungal networks threading through forest soils, Hooper makes a compelling case that relationships and symbiosis are overlooked fundamental aspects of evolution.

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.

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!)

Friend of the pod Professor Clare Collins returns to dive down into the sticky depths of the surprisingly powerful world of honey - far beyond being "just a sugary liquid". From the hallucinogenic "mad honey" of the Rhododendrons to the science behind medical-grade honey dressings that can heal wounds days faster than conventional treatments, Dr. Clare explains why this ancient food deserves a second look.
We dive into honey's beneficial micronutrients, anti-inflammatory properties, and why the nutritional profile can vary dramatically depending on where bees source their pollen. Clare also busts the myth that honey is "bee vomit", revealing the fascinating biology behind how bees actually make honey and why these incredible insects deserve our respect!

What is the universe actually made of? Particle physicist Theresa Fruth join us at Shirtloads to explore one of science's greatest unsolved mysteries - dark matter! Making up roughly 85% of the universe, yet appearing in none of our known particles, dark matter is invisible, elusive and almost certainly the reason the universe (and us!) exist at all.
Theresa and her team are hunting for it anyway. Working 1.2 kilometres underground in a converted gold mine in regional Victoria, they're searching for WIMPs - weakly interacting massive particles - in one of the quietest, most interference-free environments on Earth. The lab is being built out now, and further experiments are on the horizon. We may be closer to one of the biggest discoveries in scientific history than we realise.

Professor Ollie Jay, a leading expert in heat and health, returns to Shirtloads to discuss the growing toll of climate change on human wellbeing and global economics. Insights drawn from the latest Lancet Countdown report show that over half a million people die from heat-related causes each year, and a million more from fossil fuel pollution - deaths that are largely preventable.
Rising temperatures are quietly reshaping our daily lives, from reducing physical and cognitive productivity, to costing the global economy an estimated trillion dollars annually. But it's not all bleak - Professor Jay highlights that meaningful change is within reach. With the right political action and long-term interventions, we can protect both public health and economic stability - the solutions are already in our hands.

In this episode, we speak with Professor Emmanuel Stamatakis about Vigorous Intermittent Lifestyle Physical Activity (VILPA) - short bursts of high-intensity movement built into everyday life, like walking briskly or carrying groceries. With only a quarter of adults exercising regularly, his research highlights how incidental activity, when done with enough intensity, can offer meaningful health benefits.
We discuss how VILPA is grounded in observational research and the idea of "exercise snacks" which describes quick, accessible moments of effort that add up. The focus is on helping people recognise and maximise these daily opportunities to improve fitness and support long-term health.

We're living through the great Space Boom and with great innovation comes a lot of whacky ideas... Astronomer and Associate Professor Michael Brown from Monash University joins me to discuss stupid things in space. The conversation dives into some of the more bizarre and ambitious ideas circulating the space industry, from firing villains and radioactive waste in to the sun to deploying giant orbital mirrors to light up Earth's dark side. Brown breaks down why many of these concepts are far less practical than they sound. With over 15,000 satellites circling earth, Brown also examines the promises and downsides of mega-constellations like Starlink, including how they operate and the challenges they pose for astronomers and the environment.
It's a fascinating and critical peek in to the intersection of innovation, risk, and imagination in the new space age.

In this episode I sit down with Professor Conny Aerts, a pioneering mathematician and founding figure of astroseismology, who reveals how scientists are "listenting" to stars to understand what's happening deep inside them. From oscillating stars to solar sunquakes, she explains how sound waves can measure the sun's size, age and activity.
Beyond the science, she shares her remarkable journey from a small rural town in Belgium where she had to attend an all-boys school, the only school near her family home. She was expected to become a seamstress but Conny's dreams were beyond this planet, leading her on a path toward becoming a highly acclaimed asteroseismologist.

We're scared to say the D word! But why is talking about death such a taboo? Dr. Hannah Gould, a cultural anthropologist at the University of Melbourne, joins me to discuss the topic in the wake of the release of her new book 'How To Die in the 21st Century'. The discussion dives in to the modern experience of dying, from the pressures of having a 'good death' to the reality of overly medicalised, 'prolonged dwindling'. Hannah unpacks how death isn't just biological but also cultural and legal, raising the question: When does death officially occur? The conversation is an invitation to rethink death - not as something to fear, but as something we can approach with openness, intention, and maybe even a sense of celebration

When a problem with the James Webb Space Telescope left its images frustratingly out of focus, the solution wasn't fixed in space... it was fixed from Earth. At the University of Sydney, PhD students Dr. Louis Desdoigts and Max Charles spent two years rewriting and refining code to recalibrate a critical instrument designed by Professor Peter Tuthill: the Aperture Masking Interferometer.
Their breakthrough sharpened the telescope's infrared vision unlocking clearer views of distant worlds, including volcanic activity on Io, one of Jupiter's moons. In a fitting tribute, the pair even got matching tattoos of the hardware they helped fix! Not only did their work restore clarity to one of humanity's most powerful observatories, it also saved NASA the immense cost and impossibility of repairing the telescope in space.

***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.
