The latest edition of the Proceedings of the Royal Society of Victoria is now online, featuring a new species of calcareous sponge discovered in Geelong, a spectacular new H5 meteorite in Maryborough, an account of Indigenous meteorological knowledge using stellar scintillation, a reclassification of fossil graptolites from the early Bendigonian, a case for regulated investment in a resilient electricity network, an account of the Bureau of Meteorology’s new extreme heatwave event forecasting service, and a discussion on whether a similar service might be required for cold extremes.

Dr Duane W. Hamacher’s work seeks to understand how the first Australians developed and embedded scientific information into their knowledge systems. Working closely with Aboriginal and Torres Strait Islander elders, students, and knowledge custodians across Australia, he listens to their stories, songs, and traditions to learn about Indigenous astronomical and geological knowledge, and understand the connections between sky, land, and sea.
