Next-generation ocean current forecasting to improve maritime safety . This project aims to measure upper ocean currents at scales of 10-100 km in Australia's marine estate using pioneering satellite radar technology. The Surface Water and Ocean Topography (SWOT) mission will map currents at 10 times the resolution of present-day satellites and revolutionise our understanding of ocean dynamics. Expected outcomes include validation of SWOT data in Australian waters and merging this data into Bure ....Next-generation ocean current forecasting to improve maritime safety . This project aims to measure upper ocean currents at scales of 10-100 km in Australia's marine estate using pioneering satellite radar technology. The Surface Water and Ocean Topography (SWOT) mission will map currents at 10 times the resolution of present-day satellites and revolutionise our understanding of ocean dynamics. Expected outcomes include validation of SWOT data in Australian waters and merging this data into Bureau of Meteorology ocean models. Downstream benefits include improved ocean forecasts for maritime safety, search-and-rescue, spill modelling, and marine conservation. At the same time, the project will build sovereign capability in emerging remote sensing technology with a legacy beyond the life of the SWOT mission.Read moreRead less
Group A streptococcus (GAS) is a bacteria that causes a wide range of disease in humans. GAS diseases are more common in Australias Indigenous population, and other health and economically disadvantaged groups than more affluent groups. In this study we will evaluate the effectiveness of novel vaccine candidates designed to prevent infection from all strains of GAS.

Summary
Bioaffinity mass spectrometry infrastructure to identify small molecules binding to therapeutic targets. The development of anti-infective therapies is challenging because the underlying biology and biochemistry of pathogen virulence is not yet completely understood. This mass spectrometer facility will be used to identify small molecules suited for development into new therapies for malaria, tuberculosis and HIV.
Development of small molecule primary sulfonamides as new drugs for malaria. Malaria is a major global health threat, causing approximately 800,000 deaths annually. Lives can be saved if patients are treated. The use of current antimalarial drugs is limited by drug resistance, low activity and poor safety. This project investigates the effectiveness of a new class of molecule as a safe drug treatment option to kill malaria parasites.
Movement of mitochondria between cells. This project aims to characterise how mitochondria move between cells into grafted cells with dysfunctional mitochondrial function. How mitochondria reach the acceptor cell and how they move from the donor cell is not known. The project will use a 'bottom-up' approach, starting from a reconstituted system, via in vitro, co-culture stage to a relevant biological model, increasing complexity and biological relevance. It will document that the process of mito ....Movement of mitochondria between cells. This project aims to characterise how mitochondria move between cells into grafted cells with dysfunctional mitochondrial function.

The project will use a 'bottom-up' approach, starting from a reconstituted system, via in vitro, co-culture stage to a relevant biological model, increasing complexity and biological relevance. It will document that the process of mitochondrial intercellular movement is dependent on intercellular bridges and a specific mobility system. The project is of high relevance for cell biology.Read moreRead less

Summary
E-cadherin is a cell-cell adhesion protein expressed in all epithelia with essential roles in establishing cell polarity and in tissue patterning during development. In the adult, E-cadherin functions to maintain epithelial integrity. E-cadherin is also a vital tumour suppressor, protecting cells against metastatic transformation. Our earlier studies showed that E-cadherin is constantly moved, or trafficked, to and from the surface of epithelial cells. The endocytosis or internalisation of cell ....E-cadherin is a cell-cell adhesion protein expressed in all epithelia with essential roles in establishing cell polarity and in tissue patterning during development. In the adult, E-cadherin functions to maintain epithelial integrity. E-cadherin is also a vital tumour suppressor, protecting cells against metastatic transformation. Our earlier studies showed that E-cadherin is constantly moved, or trafficked, to and from the surface of epithelial cells. The endocytosis or internalisation of cell surface E-cadherin serves to regulate its role in adhesion. More recently, we and others have shown that E-cadherin is endocytosed in response to growth factors, in conjunction with the activated growth factor receptors themselves. E-cadherin can influence the trafficking and signaling of these receptor tyrosine kinases. This joint endocytosis is an elegant mechanism for the simultaneous downregulation of cell adhesion and activation of signaling for cell growth and motility. The growth and differentiation of epithelial cells during tissue patterning or morphogenesis relies critically on these endocytic pathways. Our research is aimed at defining the endosomes and cellular machinery involved in E-cadherin-receptor endocytosis, moreover we will pursue initial findings suggesting that there are different pathways and fates for E-cadherin endocytosed at the behest of different growth factors. We will study endocytosis during the processes of epithelial cyst formation and tubulation of cysts as an in vitro model for mammalian morphogenesis. These studies will provide important and novel information for understanding the roles of E-cadherin in adhesion and in growth factor signaling during epithelial morphogenesis. Ultimately these findings will be of relevance to epithelial development and the prevention of cancer.Read moreRead less
Traffic Incidents: Reducing the Impacts. Road congestion due to traffic incidents in major urban areas adversely affects traveller safety and travel reliability, and is a significant cost burden to industry and the community in social, environmental and economic terms. This project will investigate the impact of traffic incidents, with the aim being to produce outcomes that contribute to more efficient traffic management, and specifically to reducing the incident duration.

This project will investigate the impact of traffic incidents, with the aim being to produce outcomes that contribute to more efficient traffic management, and specifically to reducing the incident duration. Outcomes will include the development of decision support tools to aid in policy and operational responses, as well as the development of faster and more comprehensive accident reconstruction based on spatial information technology.
