Hydrogen fuel production from electricity and water sources, such as sea water, represents the ultimate goal for the research described here. This is part of an overall scheme, called "Artificial Photosynthesis", to generate clean renewable energy. The present project is an important step in this ambitious program and directly addresses a key hurdle which must be overcome to make artificial photosynthesis feasible. This hurdle is the efficient electrical conversion of water into hydrogen and oxygen, a two part process of which the latter is the most chemically difficult. The project aims to 'steal nature's secrets', by deciphering and then technologically mimicking the highly efficient means by which plants carry out these processes.Read moreRead less
To flee or not to flee: surviving on incomplete information. Even lowly animals, like the Australian fiddler crabs we will be investigating, are surprisingly competent in making the right decisions in complex situations. They actively acquire information and make good use of it to assure their immediate safety and their long term gains. Animals are exquisitely honed by evolution and we would benefit greatly by understanding what makes them so competent: on a theoretical level, we may learn about ....To flee or not to flee: surviving on incomplete information. Even lowly animals, like the Australian fiddler crabs we will be investigating, are surprisingly competent in making the right decisions in complex situations. They actively acquire information and make good use of it to assure their immediate safety and their long term gains. Animals are exquisitely honed by evolution and we would benefit greatly by understanding what makes them so competent: on a theoretical level, we may learn about efficient rules of good decision making and on a practical level, we may be able to design more flexible, robust and clever machines. Besides being useful in this wider context, the results of our research will thus also contribute to a new and 'sophisticated' appreciation of the cognitive design of animal.Read moreRead less

Summary
High Resolution Mass Spectrometer for (MS)n Chemical Characterisation. A Fourier transform ion cyclotron resonance ("FT-ICR") mass spectrometer equipped with electrospray ionisation (ESI) plus a "benchtop" matrix assisted laser desorption ionisation time of flight (MALDI-TOF) mass spectrometer are required to support the research of ca 28 research groups, including 44 postdoctoral fellows, and 138 honours and postgraduate students. By means of its high resolution and (MS)n capabilities, the FT- ....High Resolution Mass Spectrometer for (MS)n Chemical Characterisation. A Fourier transform ion cyclotron resonance ("FT-ICR") mass spectrometer equipped with electrospray ionisation (ESI) plus a "benchtop" matrix assisted laser desorption ionisation time of flight (MALDI-TOF) mass spectrometer are required to support the research of ca 28 research groups, including 44 postdoctoral fellows, and 138 honours and postgraduate students. By means of its high resolution and (MS)n capabilities, the FT-ICR-MS will provide key structural information on a wide range of synthetic and natural chemical substances, including sequence (e.g. peptides) and fragmentation patterns, while the MALDI-TOF instrument will be used primarily for high through-put proteomic analyses.Read moreRead less
Proteome Analysis of Plant Response Pathways to Microbial Signals in the Model Legume, Medicago truncatula. This project will investigate plant responses to soil microbes in the model legume, Medicago truncatula, to provide fundamental information needed to design crops with improved abilities to interact beneficially with soil microbes. Plant development and performance are significantly influenced by soil microbes, but it is largely unknown how the information contained in microbial signalling ....Proteome Analysis of Plant Response Pathways to Microbial Signals in the Model Legume, Medicago truncatula. This project will investigate plant responses to soil microbes in the model legume, Medicago truncatula, to provide fundamental information needed to design crops with improved abilities to interact beneficially with soil microbes. Plant development and performance are significantly influenced by soil microbes, but it is largely unknown how the information contained in microbial signalling molecules is relayed to plants. Proteome analysis and immunocytochemistry will be combined to identify and localise differentially expressed proteins in roots treated with specific microbial signal molecules. Annotated Proteome databases will be generated to strengthen and complement an international project on M. truncatula genome analysis.Read moreRead less
The mechanism of water splitting in photosynthesis. Sunlight reaching the earth is used by the vast body of plants and algae living in surface waters and on the land to drive photosynthesis. One of the most fundamental contributions that photosynthesis provides to the Biosphere is the gaseous oxygen produced by its water-splitting chemistry - ~300 gigatons of O2 are released into the atmosphere per year. However, the mechanism behind water-splitting is not precisely known. We will use a range o ....The mechanism of water splitting in photosynthesis. Sunlight reaching the earth is used by the vast body of plants and algae living in surface waters and on the land to drive photosynthesis. One of the most fundamental contributions that photosynthesis provides to the Biosphere is the gaseous oxygen produced by its water-splitting chemistry - ~300 gigatons of O2 are released into the atmosphere per year. However, the mechanism behind water-splitting is not precisely known. We will use a range of unique experimental approaches to determine the molecular mechanism of the photosynthetic water-splitting chemistry. The understanding of this reaction will provide the molecular blueprint for the development of efficient biocatalysts to generate H2 and O2 from water.Read moreRead less

The proposed research will significantly contribute to a better understanding of the wide range of physiological processes underlying mechanosensory transduction in living cells. The direct benefit for Australian science consists of: (i) strengthening international links with leading overseas laboratories, and (ii) accessing the state-of-the-art expertise not available in Australia. The acquired knowledge will aid in developing and designing artificial tactile sensors inspired by their biological models studied in this project. Long-term, the project is expected to make an original contribution towards developing new technologies and novel medical applications, both of which promise to be of great national benefit.Read moreRead less
