Lost in Science

While people talk about the weather in speculative terms, it's interesting to note that chimps may do the same, but they also share some darker human traits we may not be so proud of. And Stu finds that (of course) not everything natural is safe or good, exploring the natural (but extinct) nuclear reactors of Gabon. 

This week, Stu looks into the accuracy of AI as a medical search tool, and finds that published studies give mixed results; and Chris expands on last year's Ig Nobel Prizes to find out more about the physics of a perfect pasta sauce, and the role of emulsifiers.

Claire and Linden talk all things Artemis II this week, with a special focus on how Australia is contributing to the program. We congratulate amateur astronomers from southeastern Queensland for their recent award, and explore how you can take part in international Citizen Science Month. To find a project for you, check out SciStarter, the Australian Citizen Science Association, or Zooniverse.  

This week on Lost in Science, Claire dives into something very close to home — pregnancy — unpacking fascinating new research showing how both first and second pregnancies can reshape the brain for the long term, and what those changes might actually mean for how we think, feel and parent. Plus, it’s school holidays, and Linden’s in the kitchen cooking up some hands-on science with a true unsung h...

This week we go from fossils to fossil fuels, as Chris looks into the misclassification of the Dimetrodon and wonders why they didn't get bigger via giant spiders, and Stu drills down into the realities of Australia's oil reserves, and why our supply isn't what some people think it is. 

This week, Chris checks out a study showing carbon dioxide levels in human blood rising with greenhouse gas emissions, and contemplates the health effects; and Linden unearths a Taiwanese study that crafted artificial dinosaur eggs to determine whether the oviraptor Heyuannia sat on their nest to incubate them.

This week on Lost in Science, Claire chats with veterinary parasitologist Professor Shokoofeh Shamsi about the recent spate of shark encounters and why we still don’t fully understand animal behaviour in these moments. From parasites to changing ocean environments, it turns out there’s a whole ecosystem of missing pieces—and a growing call for deeper research to help us make sense of it all. Meanw...

Stu looks into the scientific origin of a famous album cover and how it reveals the legacy of a pioneering female astrophysicist, and Chris looks into the strange story of a tiny insect bite that can lead to anaphylaxis of a carnivorous kind. 

For our International Women's Day Special, Linden and Claire talk statistics around how to Balance the Scales for women in STEM in Australia. We also hear from women in STEM from across Australia about what International Women's Day means to them. 

This week, Linden talks to atmospheric chemist Rob Ryan about the effect on coral of changes in the air over the Great Barrier Reef; and Stu updates us on some recent findings on parasites, including a self-experiment from a researcher’s encounter with a sand flea (Tunga penetrans).

This week on Lost in Science, Claire dives headfirst into the evolutionary echidna-and-egg conundrum: which came first — the placental mammal or the mammalian egg of our humble monotreme cousins? Then Stu explores fascinating new research into how artificial intelligence might help bring people back from conspiracy theories — not by arguing louder, but by engaging directly with the evidence that c...

How can skiiers and ice skaters go so fast? It turns out, we're still not sure! And what ingredients are needed to see the northern or southern lights? Find out with Chris and Linden on this week's episode of Lost in Science. Additional show notes:To receive alerts from the Bureau of Meteorology's Space Weather Service, head to their Space Weather Service mailing list page. 

Welcome back the team for a new year, and Stu talks to Professor Tim Stinear from the Doherty institute and Director of the WHO collaborative centre on Buruli ulcer about a project tracking the prevalence of the ulcer using environmental surveillance to assess presence and provenance of the bacteria. 

Continuing our January tradition of playing highlights from the past year, Chris responds to media reports of possible over-diagnosis and over-medication of ADHD by looking at the data and current research and best practice; meanwhile Claire gets her teeth into a new, large longitudinal study that showed water fluoridation did not harm cognition or IQ.

This week Linden revisits two conversations from 2025 with champions of conservation: Professor Euan Ritchie from Deakin University and Clancy "The Bee Man" Lester. Euan and Linden discuss the 'de-extinction' of the dire wolf that was reported back in April 2025, and Clancy recounts his experiences exploring the Amazon looking for some insects to rival Australia's amazing creepy crawlies. 

Our summer series continues this week with an interview with Ted Vanderfeen, a scientist who works on space faring robotics to help explore strange new worlds. 

While we take a break we are revisiting some of our favourite stories and interviews in our summer series. This week we revisit the interview with Young Australian of the Year Dr Katrina Wruck, a groundbreaking green chemist working to break down harmful "forever chemicals." As the first Torres Strait Islander to receive an Australian of the Year award in any category, Dr Wruck shares her journey,...

Is it 2026 already? We farewell the year just gone, by remembering famous scientists who died in 2025, plus Chris tests our memory with his annual quiz of unforgettable science stories.

In this Christmas episode (our last for 2025!) the team looks at some Christmas adjacent science. Chris brings us up to date with the latest on our interstellar visitor 3I Atlas (spoiler, it's not aliens), Claire turns up the heat on the real reason Christmas cookies taste so good (hint: it's science) and Stu bags up some realities of the neuroscience of Holiday sales and how to avoid spending too...

This week Linden interviews Tammy Lee, PhD student at UWA in Perth who was crowned the winner of FameLab International in Switzerland in November. This means Australia is officially home to the world's best science communicator! Tammy talks through her research, as well as the process of taking part in one of the world's oldest science communication competitions. Watch the FameLab International fi...

This week on Lost in Science, in the lead-up to Christmas — and before our official festive special — we’re diving into the archives to revisit two of our all-time favourite holiday stories. Cat crunches the numbers on Santa’s impossibly busy Christmas Eve, using maths and physics to reveal just how many children he visits (and how he might just pull it off). Then Stu takes us on a botanical adven...

Linden and Chris talk about the funding cuts to Australian science, and Claire chats with A/Prof Jochen Kaempf from Flinders University about the algal bloom that continues off the South Australian coast. 

This week, Stu lets us into the secret world of moss, how they're different to other plants, and how they're so hardy they can even survive on the outside of spacecraft; and Claire gets her teeth into a new, large longitudinal study that showed water fluoridation did not harm cognition or IQ. Maeng, Chang-hyun et al., Extreme environmental tolerance and space survivability of the moss, Physcomitri...

Chris and Linden talk through the Prime Minister's Science prize, awarded in early November, and Linden chats with Dr. Grace Sethanant, and earthquake expert, about her work on Australia's weird earthquakes. 

This week on Lost in Science Stu checks in on the cutting edge of CRISPR — the revolutionary gene-editing technology promising to change how we treat diseases. Is it living up to the hype? And as we head into the holiday season, Chris is getting practical with physics, applying maths and motion to the age-old problem of how to pack your bag efficiently.
