The first casual running shoes were invented in the 1970s, and within 50 years, some of them are so good that they're banned for competitions. But our feet didn't evolve to wear shoes. Millenia of improvements left humans with unique, brilliantly adapted structures for movement. A big brain and fast feet took us to the top of the ancient food chain. Now, we wear shoes every day, and for myriad activities. People like Professor Glenn Lichtwark from QUT are trying to discover how we manage our movement, with or without shoes.

Eucalyptus trees define the Australian landscape. However, what sustained First Nations Australians for millennia mystified and frightened European colonisers. Now, Eucalypts are grown around the world, often causing immense damage to the local economy, environment and culture.

Just some of the deep and challenging questions that people like Professor Nao Tsuchiya from Monash University are trying to answer, using science, philosophy, psychology and maths.
