Editor's note

In museums across Australia and the world lie the remains of Indigenous Australians. In the early days of colonial Australia, these were often taken from burial sites and sold with no record of the location nor affiliation with a particular cultural group. Without knowledge of Country.

Today Joanne Wright and her colleagues describe their work to create an accurate DNA-based method for matching unprovenanced human remains with their living ancestors. Conducted in close consultation with Indigenous Australians, this is a first step towards a reliable, trusted way to return ancient people to Country.

The State of the Climate 2018 report, the latest biennial summary from the Bureau of Meteorology and CSIRO, reveals Australia is feeling the impacts of climate change in the form of worsening heatwaves, dangerous fire and drought conditions, coastal flooding, and extreme sea temperatures such as those that damaged the Great Barrier Reef in 2016-17.

Museums around the world hold remains of Aboriginal people that were often taken without permission and in the absence of accurate records. New DNA methods may help return these items to country.

  • Unpacking the history of how Earth feeds life, and life changes Earth

    Anthony Dosseto, University of Wollongong; Alexander Young, University of Wollongong; Nicolas Flament, University of Wollongong

    Although often separated as two unique subjects in science, geology and biology have been intricately intertwined since life on Earth first evolved billions of years ago.

  • Curious Kids: why are people colour blind?

    Some colour blind people only have two kinds of cone cell in their eye. Others have three kinds, but the cones do not pick up the same light waves as the cone cells in most people's eyes do.
