Genes to phenotype: Exploiting the marsupial model. This research will exploit one of Australia's finest natural resources, its marsupial fauna. The features of marsupial reproduction and development provide a unique opportunity to answer fundamental biological questions. This research will show how the minor differences in key developmental genes that have arisen in their 100 million year isolation give rise to the characteristic differences in developmental timing and reproduction between mar ....Genes to phenotype: Exploiting the marsupial model. This research will exploit one of Australia's finest natural resources, its marsupial fauna. The features of marsupial reproduction and development provide a unique opportunity to answer fundamental biological questions. This research will show how the minor differences in key developmental genes that have arisen in their 100 million year isolation give rise to the characteristic differences in developmental timing and reproduction between marsupials and other mammals. The focus on reproduction and development will also provide invaluable knowledge to underpin efforts to conserve our endangered species and to control those that are overabundant.Read moreRead less
Domestic air quality: towards the setting of guidelines. Air quality standards have been developed to protect human health. Although people spend most of their time indoors there are no standards and only a few guidelines for indoor air pollution (IAP). The aim of this study is to investigate the levels of IAP that may worsen asthma in children. Childhood asthma will be used as a health indicator due to its high prevalence, cost to the healthcare system and implications for respiratory morbidity ....Domestic air quality: towards the setting of guidelines. Air quality standards have been developed to protect human health. Although people spend most of their time indoors there are no standards and only a few guidelines for indoor air pollution (IAP). The aim of this study is to investigate the levels of IAP that may worsen asthma in children. Childhood asthma will be used as a health indicator due to its high prevalence, cost to the healthcare system and implications for respiratory morbidity in adult life. We expect to identify levels of IAP that will represent a health risk as well as the factors that may contribute to increased IAP in homes.Read moreRead less
Gravitational-wave astrophysics of binary black holes. Do black holes live alone, or form lasting gravitational partnerships? This question is of immense significance to astronomers. The emerging field of gravitational-wave astronomy is set to provide the answers. This project aims to develop innovative strategies to search for black hole pairs using leading technologies built with Australian expertise.
Testing pulsar emission models and general relativity at pico arcsecond resolution. A holographic technique has been pioneered that harnesses scattering in interstellar space to resolve the emission from pulsars at a resolution of 50 pico-arcseconds, six orders of magnitude finer than has been achieved by conventional radio astronomical interferometry. This project will directly measure the size of the emission regions in a set of pulsars, and hence resolve the 40-year old debate regarding the s ....Testing pulsar emission models and general relativity at pico arcsecond resolution. A holographic technique has been pioneered that harnesses scattering in interstellar space to resolve the emission from pulsars at a resolution of 50 pico-arcseconds, six orders of magnitude finer than has been achieved by conventional radio astronomical interferometry. This project will directly measure the size of the emission regions in a set of pulsars, and hence resolve the 40-year old debate regarding the site of their radio emission. The project will also apply the technique to binary pulsar systems to provide a new test of General Relativity.Read moreRead less
Controlling parametric instabilities in advanced GW detectors. This project aims to solve the problem of parametric instability in gravitational wave detectors to support an international large-scale physics experiment. The project is part of Australia’s participation in the new advanced LIGO (Laser Interferometer Gravitational-Wave Observatory) gravitational wave detectors that have been designed to achieve the first detection of gravitational waves. A 2005 prediction made by the project leader ....Controlling parametric instabilities in advanced GW detectors. This project aims to solve the problem of parametric instability in gravitational wave detectors to support an international large-scale physics experiment. The project is part of Australia’s participation in the new advanced LIGO (Laser Interferometer Gravitational-Wave Observatory) gravitational wave detectors that have been designed to achieve the first detection of gravitational waves. A 2005 prediction made by the project leaders that the detectors would experience acoustic instabilities was confirmed during detector commissioning in 2014. The project team plans to work closely with the detector designers and commissioners to solve this problem and allow the detectors to achieve their target sensitivity.Read moreRead less
Weighing the Universe using fast radio bursts. Fast radio bursts are a newly-discovered astronomical phenomenon whose millisecond-timescale emission occurs at cosmological distances, rendering them exceptional probes of the matter that lies in intergalactic space. This project aims to measure the positions and obtain the distances to these bursts to make a direct measurement of the density of ordinary matter in the Universe, at least 50 per cent of which is believed to remain undetected in inter ....Weighing the Universe using fast radio bursts. Fast radio bursts are a newly-discovered astronomical phenomenon whose millisecond-timescale emission occurs at cosmological distances, rendering them exceptional probes of the matter that lies in intergalactic space. This project aims to measure the positions and obtain the distances to these bursts to make a direct measurement of the density of ordinary matter in the Universe, at least 50 per cent of which is believed to remain undetected in intergalactic space. This project will measure the distribution of this missing matter, and find how it has evolved throughout the history of the Universe. This will provide significant benefits, such as addressing two fundamental questions about our Universe: how much matter does it contain, and has a large fraction of it hitherto evaded detection in intergalactic space?Read moreRead less
Extrinsic Control of Mammalian Germ Cell Delineation. Australia is a leader in the recent exciting breakthroughs in reproduction and development, such as cloning and embryonic stem cell propagation, and understanding how germ cells are specified would help us understand the biology underlying specification and developmental potential of all cells. This research will continue to contribute to maintaining Australia's high reputation in advances in reproductive biology. In addition, a greater under ....Extrinsic Control of Mammalian Germ Cell Delineation. Australia is a leader in the recent exciting breakthroughs in reproduction and development, such as cloning and embryonic stem cell propagation, and understanding how germ cells are specified would help us understand the biology underlying specification and developmental potential of all cells. This research will continue to contribute to maintaining Australia's high reputation in advances in reproductive biology. In addition, a greater understanding of marsupial reproduction is a high priority for Australia in the 21st century, with its current unacceptably high rate of mammalian extinctions, for 'we cannot conserve until we comprehend' (Short, 1985).The results therefore are of great potential benefit to society.
