The Science Show

Join us for highlights from fifty years of The Science Show including Fred Dagg, who helps us with the big questions: what is it all about and why are we here?

Every now and again, dozens or even hundreds of perfectly healthy looking whales strand themselves on a beach. Scientists have a few theories on why they do this. 

Samples from asteroids have helped build a theory of the origin of complex molecules and how they made it to Earth.

Fresh Australian dietary guidelines are due next year, and they’ll likely focus on the health of the planet as well as people.

Small chemical groups inserted or removed from around DNA may affect gene expression and so be a way to control genetic blood disorders such as sickle cell anaemia and beta thalassemia. 

Meat ants don't sound like the most endearing Australian animals. These purple-red insects are super territorial, swarming and biting anything that threatens their nest. But it turns out they're not just aggressive, flesh-tearing fighters. They're also farmers, architects, and — best of all — cane toad exterminators. 

Is the US shooting itself in the foot, or shooting itself in the head? As Donald Trump removes funding for medical research, climate research and more, Matthew England reflects on how science will help us cope with a changing world.

Cassandra Rout, a microplastics researcher at the University of Queensland, dives deep into the pervasive issue of microplastics in our lives. She discusses alarming health risks, including their potential links to serious conditions like heart attacks and cancer. Listeners learn about a French pilot study revealing microplastics in homes, the surprising impact of dishwashers on our food supply, and practical tips to minimize exposure. Cassandra emphasizes the urgency of addressing this ubiquitous pollution and our role in the fight against it.

A 100-yr flood is now a more regular occurrence in the German town of Passau, bringing widespread destruction, another local impact of a planet getting hotter.

Tim Gould, a quantum chemist from Griffith University, unpacks the everyday magic of quantum mechanics. He highlights how quantum principles power everything from laser barcode scanners to the efficient LED bulbs we use daily. The conversation emphasizes the crucial role of quantum tunneling in USB memory sticks and the surprising ways quantum mechanics enhances photosynthesis, making plants more effective at energy conversion than solar cells. Gould’s insights reveal that quantum technology isn't just a buzzword—it's woven into the fabric of modern life!
