This epsiode Fuzzy Logic celebrates Earth Science Week with Geoscience Australia dishing the dirt on how soil is solving crimes around Australia. Dr Patrice de Caritat starts the episode by sharing how researchers in Canberra trialled a new method of tracking criminals using soil. Next up, Natalie Schroeder takes us back in time to share how Australia's first female Commonwealth palaeontologist helped to solve a crime in 1952 using her knowledge of fossils. Finally, Dr Keith Sircombe explains how a machine that uses radioactivity to date ancient rocks was used to match gunshot residue. A show full of ground-breaking research. Special thanks to Geoscience Australia for access to these amazing earth scientists.

The climate change problem is immense and it can feel like we're helpless. Yet in our own way there is a lot we can do.

Today on Fuzzy Logic we met people from different backgrounds who demonstrate their own approaches to the problem.

This week Broderick dives into the quirky world of the Ignobel Prizes. With talking cats, old chewing gum and beard research we hope this episode will make you laugh and make you think!

In this National Science Week episode of Fuzzy Logic, Broderick explores the geological journey that has occurred to bring food to our plate. Joined by expert scientists from Geoscience Australia, this episode highlights how closely linked our food is to the geology that surrounds us.

Guests include Dr Steve Hill, Chief Scientist at Geoscience Australia, Dr Claire Phillips, a remote sensing scientist, and Amy Peterson, Team Lead for the Global Navigation Satellite Systems.

Michael Jennnions is a evolutionary/behavioural ecologist from the Research School of Biology at the Australian National University (ANU).  We discuss what it is to be a behavioural ecologist, some of his work on mosquito fish and his thoughts on how to improve the incentives and process of science publication.

Interviewed by Tom 

Taryn Laubenstein from Future Earth Australia discusses her journey into science, adaptations of sneaky corsican fish and her current work on bringing together scientists, community and industry to develop a vision for the future of Australia's coastal and offshore marine ecosystems.

Interviewed by Tom

From The Garden of Eden until today, gardens have a special place. There's a special joy, the quiet contemplation of connecting with a small plot of nature.

Each week on radio 1RPH, Camilla presents her gardening program. On this occasion she talks to Rod about his book Ten Journeys on a Fragile Planet.

Reducing the environmental footprint of a city is an enormous job, with many threads and engaging many people from diverse backgrounds.

While Canberra has shown itself to be a world leader, there's still a very long way to go. How do we get there?

In this wide ranging discussion, ACT Environment Minister Rebecca Vassarotti and Dr Ann Hill from the University of Canberra share their thoughts with Rod.

In this conversation we mention an online event at 3pm 5 August with themes around Ten Journeys on a Fragile Planet.

Back in 1980 Alvin Toffler introduced the idea that we are entering the Third Wave, the Information Age. Now see how that has progressed forty years on.

The rate of change has been stupendous and the implications deep. It has profoundly changed society in ways we did not predict. With our guest, Tom Worthington, we talk about how we are dependent on working system. What happens, and why do they sometimes fail?

Tom Worthington is an independent computer professional, educational design consultant and an Honorary Senior Lecturer in the School of Computing at the Australian National University.
