By Professor James Hurley Published on August 13, 2024 There are over 30 trillion bacterial and fungal cells in the human microbiome. Most are harmless to us, their host, but some are not.

By Associate Professor Daniel Little Published on August 8, 2024 Students were asked to draw lines through scatterplots. Use the slider to see the results. Pictures: Supplied Our research found several interesting things. Some people drew lines which were approximately polynomial mathematical functions, following the global trends in the data. Others generated functions that tracked the local changes in the dots, moving up and down with each data point. But this tendency to ‘see’ more of a local pattern was more pronounced when there were fewer data points.
By Dr Kelly Kirkland Published on August 7, 2024 This year – 2024 – is a year that will test the strength of global democracies. As we reach the halfway point of ‘election year’, many parts of the globe feel as divided as ever. In the US for example, moral outrage towards the ‘other side’ is rife.
