Atmospheric CO2, global temperature, and surface ocean acidity response to fossil carbon burning - insights from an ancient analogue. Sequestration of anthropogenic CO2 emissions by the oceans and the impacts of resulting ocean acidification and greenhouse warming upon marine ecosystems are vital to understanding the course of future environmental change. This research will improve knowledge of the biological and chemical responses in the ocean to past changes in atmospheric CO2 levels and incre ....Atmospheric CO2, global temperature, and surface ocean acidity response to fossil carbon burning - insights from an ancient analogue. Sequestration of anthropogenic CO2 emissions by the oceans and the impacts of resulting ocean acidification and greenhouse warming upon marine ecosystems are vital to understanding the course of future environmental change. This research will improve knowledge of the biological and chemical responses in the ocean to past changes in atmospheric CO2 levels and increased ocean acidity. This will assist in predicting the consequences of different fossil fuel burning scenarios for climate and marine life, especially the future viability of organisms like corals, molluscs, and calcareous plankton that underpin key tourism and marine production systems.Read moreRead less

Iron in the Antarctic sea ice zone and its role in the past and future climate. The Antarctic sea ice environment has remained poorly investigated for decades as it is difficult to access. Recent scientific advances have revealed that melting sea ice may provide a significant amount of the plant micro-nutrient iron to the Southern Ocean. Given that polar waters are iron-deficient and seasonal sea ice affects ~14 million square kilometres of ocean, the importance of iron fertilisation from deca ....Iron in the Antarctic sea ice zone and its role in the past and future climate. The Antarctic sea ice environment has remained poorly investigated for decades as it is difficult to access. Recent scientific advances have revealed that melting sea ice may provide a significant amount of the plant micro-nutrient iron to the Southern Ocean. Given that polar waters are iron-deficient and seasonal sea ice affects ~14 million square kilometres of ocean, the importance of iron fertilisation from decaying sea ice and its effect on global climate urgently need to be evaluated. This proposal aims at improving our understanding of Earth's complex system, and will inform future climate change policy in Australia.

Beyond oceanography: behavior as a tool to uncover ocean complexity. It is crucial that Australia remains a world leader in marine biology and ecology and continues to preserve the uniqueness of its marine environment through the development of integrated inter-disciplinary research projects.

It is crucial that Australia remains a world leader in marine biology and ecology and continues to preserve the uniqueness of its marine environment through the development of integrated inter-disciplinary research projects. This project will open a new area of research at both the national and international levels through the first integrated approach of the behavioural mechanisms that rule the base of the ocean food web structures and functions. The present work is also expected to open new perspectives in fields such as biological oceanography, microbial ecology, plankton ecology, behavioural ecology through the exploration of previously untapped areas of research.Read moreRead less

Membrane Protein Structure and Interaction Facility. While it is estimated that a third of the human genome encodes for membrane proteins, the structures of only relatively few membrane proteins are currently known. It will be some time before membrane protein structure determination becomes routine, yet over 50% of the drugs on the market today rely on the activity of membrane proteins for their efficacy. This application seeks to establish a Membrane Protein Structure and Interaction Facility ....Membrane Protein Structure and Interaction Facility.

It will be some time before membrane protein structure determination becomes routine, yet over 50% of the drugs on the market today rely on the activity of membrane proteins for their efficacy. This application seeks to establish a Membrane Protein Structure and Interaction Facility for the development and application of novel techniques and approaches to study the structure and interactions of membrane proteins. Research progress will be greatly enhanced by the establishment of this dedicated facility with cutting-edge technologies for the study of membrane proteins.Read moreRead less
Benign fabrication of microfluidic hydrogel for improved artificial vasculature in bone implants. We will create a benign technology for synthesising microfluidic hydrogels to generate artificial vascultures in bone implants. It is a critical step to enable the use of tissue-engineered vital organs, such as bone, heart and kidney in patients with end-stage organ failure. Thicker scaffolds will be possible, as the vasculature will provide nutrients and oxygen for cells to grow into 3D scaffolds. ....Benign fabrication of microfluidic hydrogel for improved artificial vasculature in bone implants.

We will also develop in-situ imaging analytical protocols for the rapid analysis of broad arrays of functional molecules, with significant bearing on BioMEMS design to develop methods for diagnosis of fatal diseases.Read moreRead less
Biodegradable polymeric microparticles for targeted delivery. The use of microparticles with tuneable physicochemical properties and loading characteristics is of interest in the fields of biomaterials, drug delivery and imaging. Such engineered particles are likely to address problems associated with conventional drugs and drug carriers, including poor disease site selectivity, polymer toxicity, non-biodegradability and free diffusion of drugs throughout the body. These microparticles may provi ....Biodegradable polymeric microparticles for targeted delivery. The use of microparticles with tuneable physicochemical properties and loading characteristics is of interest in the fields of biomaterials, drug delivery and imaging. Such engineered particles are likely to address problems associated with conventional drugs and drug carriers, including poor disease site selectivity, polymer toxicity, non-biodegradability and free diffusion of drugs throughout the body. These microparticles may provide direct advantages to society, including minimally invasive and fast in-vivo diagnostics, localised delivery of drugs and therapeutic agents with increased bioavailability, patient acceptability and reduced healthcare costs.Read moreRead less

The future of biomaterial science in Australia depends upon the discovery and refinement of new materials. This project characterizes the biomaterials in the feeding apparatus of Australian marine chitons (Mollusca: Polyplacophora). Like many biological structures, chiton teeth are sophisticated composite materials that have been refined by evolution over millions of years. Initially composed of the polysaccharide chitin, these extremely hard teeth are mineralized with calcium and iron compounds and used to excavate the rocks on which they live, as they graze for food. Understanding the mechanism of biomineralization is vital for devising synthetic routes to composite materials for industrial purposes.Read moreRead less
