This project aims to capitalise on recent developments, that have shown that previously accepted theories are deeply flawed, in various applications in fundamental physics and in unsolved problems in biology that involve electromagnetic fields. Interactions driven
by electromagnetic fluctuation forces, and real photon exchange, between molecules will be investigated. The project will investigate how dispersion interactions change in mesoscopic pores, in electrolytes, and at finite temperatures. Applications involve
catalysis, molecular formation, and quantum logic. The project also aims to develop a unified theory for energy and charge transfer, relevant for photosynthesis and the way biological molecules transfer information.Read moreRead less
Mitochondrially targeted anti-cancer drugs modulate the mitochondrial genome. Successful cancer management requires novel therapeutical approaches. This project will test the effect of a new class of compounds that target mitochondria, the powerhouse of the cells, where they suppress expression of mitochondrial genes. By this mechanism, cancers that are resistant to apoptosis induction can be inhibited.
Continuous Reaction Networks that Model Chemical Evolution of RNA. This Project aims to develop experimental models for chemical evolution that may have happened on the early Earth and which were important to the emergence of life. This Project expects to uncover synthetic pathways for ribonucleotide production using a combination of ionizing radiation and dry-wet cycles. Expected outcomes include an increased understanding of the range of physical and chemical parameters that will allow for rib ....Continuous Reaction Networks that Model Chemical Evolution of RNA. This Project aims to develop experimental models for chemical evolution that may have happened on the early Earth and which were important to the emergence of life. This Project expects to uncover synthetic pathways for ribonucleotide production using a combination of ionizing radiation and dry-wet cycles. Expected outcomes include an increased understanding of the range of physical and chemical parameters that will allow for ribonucleotide production to occur under the proposed geochemical settings. The knowledge gained in this Project will benefit the understanding of the chemical evolution of complex chemical mixtures relevant to early Earth environments and provide new mechanisms for how ribonucleotides could have arisen abiotically.Read moreRead less
Quantum Mechanics and Planetary Atmospheres.

The project will increase the visibility and status of Australian research, by the participation of researchers and students in a wide international collaboration, covering experiments, theory, and computation, which will solve a fundamental research problem that has previously defied understanding. The resulting nitrogen model will be relevant to the important fields of global and planetary atmospheric change, and will find immediate application in the analysis of results from the NASA missions, Voyager, Cassini, and (later) New Horizons. In the experimental part of the project, an Australian-first extreme-ultraviolet laser facility will be developed which will provide research opportunities complementary to the Australian Synchrotron.Read moreRead less
Synchrotron developments of new techniques in X-ray interactions with matter, resolving major discrepancies in Quantum Physics and Chemistry. Synchrotron science is a priority area for Australia, the USA, and most first world countries.

Synchrotron science is a priority area for Australia, the USA, and most first world countries. Development of new ideas and tools for X-ray investigations is the key to future opportunities and is the subject of this proposal. We will develop new techniques for crystallographic electron-density studies, X-ray Anomalous Fine Structure (XAFS) and Multiple-wavelength Anomalous Dispersion (MAD), and provide useful advances for X-ray lithography and radiography. Simultaneous investigation of form factors, absorption coefficients, anomalous dispersion and X-ray scattering will provide new experimental tests of relativistic atomic wavefunction calculations, molecular bonding and solid state coupled cluster theory. Major discrepancies will be resolved.Read moreRead less
The Total Column Carbon Observing Network in the Southern Hemisphere: constraining our understanding of the carbon cycle and climate. The global carbon cycle and the distribution, sources and sinks of greenhouse gases such as carbon dioxide and methane are crucial drivers of climate change. The Total Carbon Column Observing Network (TCCON) measures the amounts of greenhouse and other trace gases in the atmosphere by solar remote sensing from the ground with unprecedented accuracy and precision. ....The Total Column Carbon Observing Network in the Southern Hemisphere: constraining our understanding of the carbon cycle and climate. The global carbon cycle and the distribution, sources and sinks of greenhouse gases such as carbon dioxide and methane are crucial drivers of climate change. The Total Carbon Column Observing Network (TCCON) measures the amounts of greenhouse and other trace gases in the atmosphere by solar remote sensing from the ground with unprecedented accuracy and precision. TCCON data are the "gold standard" for total column measurements and an essential part of greenhouse gas science. They are used to improve knowledge of the carbon cycle and future climate change, both directly and by validating global-scale satellite measurements. This project will continue to expand TCCON in the southern hemisphere and the enhanced scientific understanding it will provide.Read moreRead less
Novel platinum(IV) complexes that are targeted to and trapped by tumours and tumour cells. Platinum complexes continue to be a mainstay in the treatment of solid tumours and their combination with molecularly targeted agents selected for the type of tumour and the mutations identified is expected to lead to continued growth in their use.

Platinum complexes continue to be a mainstay in the treatment of solid tumours and their combination with molecularly targeted agents selected for the type of tumour and the mutations identified is expected to lead to continued growth in their use. However, their toxicity remains a major impediment to their use and effectiveness and therefore, this project aims to develop less toxic analogues that are as least as effective as current drugs. This project will combine recent developments in stabilisation and cellular trapping of platinum(IV) pro-drugs with a range of strategies designed to limit activation of these pro-drugs to the tumour environment.Read moreRead less
Gamma-ray spectra from electron-positron annihilation in molecules. Positrons and molecular electrons interact in new ways as compared to the electrons themselves, thus providing novel chemical possibilities. Australian expertise and the best available elsewhere will be combined to produce important new scientific results in this area and provide major training opportunities for young researchers.

The Contribution of Tropical Cyclones to the Earth Energy Budget. This project aims to quantify the tropical cyclone contribution to the earth energy budget to understand whether tropical cyclones feed back to the climate system. While existing literature focuses exclusively on the effects of climate change on tropical cyclone variability, this project switches this viewpoint around. One possible outcome is a better understanding of long-term tropical cyclone variability. This is particularly im ....The Contribution of Tropical Cyclones to the Earth Energy Budget. This project aims to quantify the tropical cyclone contribution to the earth energy budget to understand whether tropical cyclones feed back to the climate system. While existing literature focuses exclusively on the effects of climate change on tropical cyclone variability, this project switches this viewpoint around. One possible outcome is a better understanding of long-term tropical cyclone variability. This is particularly important for tropical cyclone vulnerable regions including the Australian east coast and the oil and gas industry off the Northwest Shelf. Furthermore, the anticipated knowledge gained by this project will inform international understanding on the impacts of tropical cyclones to the overall climate system.Read moreRead less
