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.
