This week on Lost in Science, Claire chats with Dr. Matthew Snelson about how our diet affects gutmicrobiome health and the link with chronic diseases. And we dig into the archives with Chris to explore space junk—who's responsible for putting it up there, tracking it, and bringing it down.
-
Is it just Chris or are elections getting closer and closer of late? He spoke to psephologist Adrian Beaumont and was surprised by what he was told. And Stu has been looking at the moon and finding out there's more discoveries about the moon all the time, and not just regarding our local satellite(s).
-
This week, Cat tells us what makes a moon, and how they can only orbit us temporarily like Earth’s latest mini-moon 2024 PT5; and Claire takes us underground and underwater as she speaks to palaeontologist Meg Walker about diving for megafauna fossils in South Australia’s limestone caves.
-
This week on Lost in Science, Chris investigates fresh research into the mysterious Wow! signal detected by the Big Ear radio telescope, and could it be evidence of a weird cosmic outburst? Meanwhile, Stu takes us on a journey through the sky—examining how microbes hitch a ride on atmospheric currents, traveling vast distances across the planet. How far can these tiny travelers go, and where do their limits lie? Tune in to find out!

How can a plant imitate the leaves of a plastic plant when it has no eyes, and no brain? How can a dead fish swim? Can animals breathe through their bums? These are the questions that have driven scientists and philosophers to insomnia and madness for centuries, but now, the Ignobel prizes has brought their answers to light.

This week, Stu tells us about new research making animals invisible, or rather their tissue transparent, using a common food dye; and Cat tells us about how humpback whales make and use nets of bubbles as tools for hunting, and recently discovered secrets of their mating and birth.Zihao Ou et al. Achieving optical transparency in live animals with absorbing molecules. Science 385, eadm6869(2024). DOI:10.1126/science.adm6869Andrew Szabo et al. 2024.

This week on Lost in Science, we're taking a trip back in time to revisit two fascinating stories! First up, Chris dives into the curious world of cat taste—exploring why our feline friends are such picky eaters and the evolutionary reasons behind their unique palate. Then, Claire catches up with Dr. Julie Old to chat about the incredible wombat and the groundbreaking citizen science project, WomSAT - www.womsat.org.au. Discover how this initiative is making a difference for wombat conservation and how you can get involved.

This week, Chris speaks to virologist Assoc. Prof. Kirsty Short from the University of Queensland about their new online calculator which estimates your risk of adverse COVID-19 outcomes and Long Covid; and Cat tells us about how skyglow blocks our view of the stars and First Nations' Sky Country, and why it should be possible to fix.COVID-19 Risk Calculator: https://corical.immunisationcoalition.org.au/longcovid
-
This week on the show, Claire dives into an innovative strategy to protect freshwater crocodiles from deadly cane toad poisoning by, surprisingly, giving them a taste of food poisoning first. Meanwhile, Stu explores groundbreaking research into cellular aging, shedding light on what really makes us age and how we might slow down the clock.
-
This week, Chris talks to astrobiologist David Flannery about the discovery by NASA’s Perseverance Rover of potential biosignatures in a rock on Mars, and what’s needed to verify it; and Cat examines the question of whether the swimming pool at the Paris Olympics was really slower to swim in.
-
Stu looks at some name changes in the botanical world that may not change everyone's world, but could have a positive impact for some. Claire talks to Ollie Jones about the true risk of some chemicals that get a lot of attention from the media, but may not be as threatening as they are made out to be.

This week, Cat tells us about nanobodies, the smaller versions of antibodies that camelids like llamas and alpacas have, and how they could help combat HIV; and Chris clues us into the closest known black hole in our galaxy, and a much larger one thousands of times the mass of our Sun, hidden inside a star cluster.Jianliang Xu et al., Ultrapotent Broadly Neutralizing Human-llama Bispecific Antibodies against HIV-1.

All we can do is step back in time. This week we go back to Claire's first ever story on the air about virgin births in the animal kingdom, and also listen back to Dr. Manisha Bhardwaj tell us about how bacteria may save bats from a dreaded fungal disease in her first story on the show.

This week on Lost in Science, are you an early bird or a night owl? How does your sleep preference affect your body? Stu delves into the latest research on sleep, uncovering fascinating insights and practical tips. Meanwhile, Cat takes us on a cosmic journey, exploring the health challenges astronauts face in microgravity. From space illnesses to the science of sleep, tune in for an out-of-this-world episode that’s sure to keep you awake and curious!

In our woolliest episode ever, Claire tells the tale of the woolly mammoth and new research on the last known individual, called Lonely Boy; and coincidentally Chris excavates a new study on the population dynamics of the woolly rhinoceros, and its extinction from climate change and human hunting.Dehasque et al. 2024. Temporal dynamics of woolly mammoth genome erosion prior to extinction. https://doi.org/10.1016/j.cell.2024.05.033Fordham et al. 2024. 52,000 years of woolly rhinoceros population dynamics reveal extinction mechanisms. https://doi.org/10.1073/pnas.2316419121
