Harry Messel has been a powerful force in science education—from the Physics Foundation to textbooks and his establishment of International Science Schools. He was awarded the Academy Medal.
Simon McKeon is a prominent business leader and philanthropist who has made extensive contributions to Australian science and innovation including chairing the CSIRO Board and the agenda-setting McKeon report into medical research in Australia. He was awarded the Academy Medal.
The life and death of cells: Jerry Adams has advanced understanding of cancer development, particularly of genes activated by chromosome translocation in lymphomas. By clarifying how the Bcl-2 protein family controls the life and death of cells, he and his colleagues at the Walter and Eliza Hall Institute of Medical Research have galvanised the development of a promising new class of anti-cancer drugs. Jerry was awarded the 2014 Macfarlane Burnet Medal. Continue reading Australian Academy of Science medals→
Prostate cancers are made up of hungry, growing cells. Now we’ve discovered how to cut off their food supply thanks to a study published in Cancer Research and supported by Movember. More below. Also Australian science discoveries you may have missed from the past week. Heart cells growing in a test-tube – Melbourne How birds [...]
Dr Kate Trinajstic has used synchrotron light and CT scanning to see through rock, in the process discovering how ancient fish developed teeth, jaws and even a womb. Her work is increasing our understanding of how life on Earth evolved.
About 380 million years ago in what is now the Kimberley Ranges in Western Australia, a vast barrier reef formed. In what would have been the inter-reef basins, large numbers of fish were buried relatively intact. Protective limestone balls formed around them and preserved them. When these balls are treated with acetic acid, the main component of vinegar, the surrounding rock dissolves, leaving only fossilised fish bones.
But in the course of studying hundreds of these dissolving balls, Kate began to see what looked like muscle fibres between the bones. She was eventually able to convince her colleagues that irreplaceable soft tissue detail was being lost in the acid treatments. Continue reading Seeing fish through rocks→
Thermometer-based climate records started in 1850, so scientists have gone “back to nature” for sources of long-term climatic information to help them better understand climate change and rising sea levels.
Researchers at Geoscience Australia have unravelled the development of a unique seafloor community thriving in complete darkness below the giant ice sheets of Antarctica.The community beneath the Amery Ice Shelf in Antarctica is 100 kilometres from open water and hidden from view by ice half a kilometre thick. This ecosystem has developed very slowly over the past 9,000 years, since the end of the last glaciation.
Today it is home to animals such as sponges and bryozoans fed by plankton carried in on the current. Dr Alix Post studied shell fossils within core samples where she unexpectedly found evidence of these isolated ecosystems.
Aboriginal Elders from the Traditional Tribal Groups in the Willandra Lakes World Heritage Area are collaborating with researchers to produce the first integrated account of the history of human settlement, landscape evolution and past environmental change for Australia’s foremost ‘Ice Age’ archive.
