Uncomfortably Curious

What is The Odyssey actually about — and why has it survived for nearly 3,000 years?Christopher Gribbin joins me to explore Homer’s Odyssey, the complicated character of Odysseus, and the world of ancient Greece behind one of the most enduring stories ever told.We discuss what we can and can’t know about Homer, whether there may be historical truth behind the Trojan War, and why translation changes the way we experience the poem. Christopher also shares his take on Christopher Nolan’s The Odyssey: what the film gets right, what it changes, and why the gods matter so much in Homer’s original.Along the way, we get into moral ambiguity, homecoming, ancient Greek religion, and the things modern audiences often misunderstand about the civilisation that produced these stories.

Dr. Paul Turke calls himself the world’s first Darwinian paediatrician. Before medical school, he spent months doing fieldwork on the tiny Micronesian atoll of Ifaluk, studying cooperative childcare and kinship networks. He then became a paediatrician and has spent the last 25 years treating kids by asking why, not just how. He is the author of Bringing Up Baby: An Evolutionary View of Pediatrics.We get into the grandmother hypothesis and what Paul actually saw in Micronesia that pointed him towards it; why modern mobility, isolation and poor health can weaken the kinship networks humans evolved to rely on; and the uncomfortable truth about “getting all the childcare bugs over with early”. We also cover co-sleeping and sleep training, a theory linking reduced holding of infants to later sensory issues, teen anxiety, screens, Australia’s social media ban, and why evolutionary explanations for health and behaviour still get pushback inside medicine.

Gautam Raju leads global policy and advocacy at Movember, sitting at the point where men's health research meets government and the algorithm. We get into why the word "masculinity" can shut a conversation down before it starts, the WhatsApp video that stopped him in his tracks — titled "how to ensure your three-year-old boy is not toxic" — and why two-thirds of young men are watching masculinity influencers regularly. We also cover Movember's push for mental health checks for new dads, a confronting stat about the health system missing men before suicide, and Gautam's own experience moving through that system as a patient. This one sits with the discomfort rather than resolving it.

Are dads actually "hard to engage", or have we just been building the wrong kinds of support?I'm joined by Simon Moore, a Geelong‑based registered nurse, founder of Strong Dads, and creator of The Wholehearted Dad Program. We talk about why he no longer buys the idea that dads are "hard to engage", the four traps he sees modern fathers falling into – provider, lone wolf, control, and competence – and the slow work of rebuilding identity once life includes a tiny human and no sleep. We also get into why three in five new Aussie dads are never asked about their mental health, and what it would take to catch them earlier rather than in crisis.If you're a dad, a partner, or someone who works with families, this one's part mirror, part map – an honest look at the pressures men are under, and what more wholehearted fatherhood could look like.

Extinction might be the rule in the universe, not the exception.Charley Lineweaver studied history and English before switching to physics — and ended up on the NASA team whose 1992 discovery of fluctuations in the cosmic microwave background, the oldest light in the universe, helped earn his PhD supervisor a Nobel Prize. He's now an astrobiologist and cosmologist at the Australian National University. With his student Aditya Chopra, he proposed the Gaian Bottleneck: the idea that most life goes extinct before it learns to regulate its own planet, and that this, not the difficulty of starting life, may explain why the universe looks so empty.We talk about:Why extinction, not emergence, might be the hard part of staying alive on a planetHis case, built on isolated ecosystems like Australia and Madagascar, that human-like intelligence may never have been an inevitable outcome of evolutionWhy he thinks maths is useless for talking to aliens, and what trying to communicate with dogs, dolphins and plants actually teaches usWhere he agrees, and where he sharply disagrees, with his hero Carl Sagan on humanity's place in the universe

A Melbourne psychiatrist spent decades building the case for psychedelic therapy — and became one of the psychiatrists pushing for Australia to legalise it.Nigel Strauss has been a psychiatrist for over 45 years, trained at the Jung Institute in Zurich, and was among the first Australian psychiatrists trained by MAPS in psychedelic‑assisted therapy in the UK in 2014. He ran Melbourne's Millswyn Clinic for around forty years, worked as a psychedelic psychotherapist on Australia's first approved psilocybin trial for end‑of‑life anxiety and depression, and personally sponsored a Monash University trial giving MDMA‑assisted therapy to 25 veterans and first responders with severe PTSD — results are being presented in Amsterdam this year, and by his account most participants have done very well. His own experience with LSD as a depressed medical student set him on this path decades before any of it was legal.We talk about what changed in the science and the culture to make Australia the first country to allow authorised psychiatrists to prescribe MDMA for PTSD and psilocybin for treatment‑resistant depression, what actually happens in a psychedelic session, what shifts in someone facing death, and why an urban psychiatrist ended up planting thousands of trees and spending decades helping protect the Great Otway region.

Concussion isn’t just “getting your bell rung” — it’s a mild traumatic brain injury that disrupts how your brain’s electrical system works, often long after the obvious symptoms settle.Neurophysiologist Professor Alan Pearce has spent more than a decade using non-invasive brain stimulation to study how the brain recovers — or doesn’t — after repeated impacts in Australian Rules football, rugby and other contact sports.Fresh from appearing on ABC’s Four Corners investigation Collision, which revealed a far higher number of former players diagnosed with CTE than previously known, Alan joins Uncomfortably Curious to dig into what’s really happening in the brain during concussion and chronic traumatic encephalopathy.We talk about the mismatch he’s found between symptom resolution and physiological recovery, why a player can feel fine while their nervous system is still compromised, and what his research shows about 12–14 day return-to-play rules versus the roughly 26-day window the brain often needs to genuinely recover.We also explore how many concussions might be “too many”, why CTE isn’t simply a concussion disease, and the cultural habits that keep athletes saying “just one more” even as the risks mount.Along the way, Alan touches on the current push to develop clinical diagnostic criteria for CTE, and where listeners can go to support the Australian Sports Brain Bank and the Concussion & CTE Foundation’s work.

What does it mean that the universe is dying — slowly, quietly, running out of usable energy? How does where a galaxy grows up shape what it becomes? And how do we actually know that the gold in your wedding ring was forged in the collision of two dead stars?Associate Professor Luke Davies is an astrophysicist at the University of Western Australia, based at ICRAR (the International Centre for Radio Astronomy Research). He leads some of the largest galaxy surveys on Earth, spending a decade mapping how a galaxy's cosmic neighbourhood shapes its growth, size, and fate — think nature versus nurture, but for entire worlds. He's also hosted Neil deGrasse Tyson and curated TEDxPerth.We talk about what it means to literally look backwards in time, why the universe's slow death is more interesting than alarming, the violent stellar collisions that forged the elements in your body, and the deep questions the field still can't answer.A conversation about galaxies, deep time, and what it looks like to spend a career staring into the past.

You can spend years building something impressive and still wonder if it's what you actually wanted.Izzy Di Domenico is a lecturer, unit chair, and nine-year Deakin veteran whose path ran through a PhD and a stint inside elite AFL.We talk about what academic life actually involves once you're in it, the identity shift a PhD quietly produces, and what it's like to step into leadership while still wondering if you really know what you're doing. We also get into AI in education — whether it's a useful tool or a crutch that stops students learning to think — and why universities are struggling to respond coherently.Underneath all of it: the pressure of your 20s and 30s to keep moving, the trap of saying yes to everything, and the slow realisation that busy isn't the same as living.If this one sounds familiar, send it to someone in their early career.

Most new dads want to be present and involved. Many quietly become passengers in their own family — and don't realise until it's already happened.Norma Barrett is a public health researcher at Deakin University who studies the transition to fatherhood — particularly why so many men show up committed and still end up feeling peripheral, guilty, or unsure of their role.We talk about what "passenger parenting" actually looks like, how it develops without men really choosing it, and whether it's possible to interrupt the drift. We also get into dad guilt and self-care, why fathers find it hard to ask for support, the pressure of the provider role, and how to speak honestly about fathers' needs without minimising what mothers carry.This is a conversation about fatherhood. But it's also about identity, relationships, and the gap between the parent you hope to become and the one early parenthood can quietly shape you into.If this episode lands for you, send it to a new dad or an expecting one.

Billy Griffiths, author of Deep Time Dreaming, is a historian who has spent years thinking about what it means to inhabit a continent where people have lived for at least 60,000 years — and how rarely that depth of time sits at the centre of how most Australians understand this country.This conversation covers how Australian archaeology went from a chaotic, under-resourced field to something more careful and collaborative — and why it took so long for ancient Australia to be taken seriously. Billy unpacks what "at least 60,000 years" actually means: what the evidence looks like, where it's contested, and what uncertainty still sits behind the number.The unanswered questions are also here: the sea crossings, the routes taken, the societies that emerged, and why phrases like "Aboriginal culture" can hide more than they reveal — alongside how imagination helps and misleads when thinking about people tens of thousands of years ago, and what new partnerships with Indigenous knowledge holders might still change the story.

Some conversations make you more certain. These ones don't.Uncomfortably Curious is long-form conversations with researchers and thinkers who are more interested in understanding than performing certainty.Hosted by Aidan Mill. New episodes weekly.
