Crop improvement using peptide regulators of growth and N demand signalling. This project aims to reduce reliance on nitrogen fertilisers without reducing crop yield. Global food security relies on using high-yielding grain varieties and nitrogen-based fertilisers. Since 1950, fertiliser use has increased 20-fold but the yield benefits of this use are declining. Crops only absorb 30–50 per cent of the applied fertiliser and the unused nitrogen causes environmental damage which is costly to mitig ....Crop improvement using peptide regulators of growth and N demand signalling. This project aims to reduce reliance on nitrogen fertilisers without reducing crop yield. Global food security relies on using high-yielding grain varieties and nitrogen-based fertilisers. Since 1950, fertiliser use has increased 20-fold but the yield benefits of this use are declining. Crops only absorb 30–50 per cent of the applied fertiliser and the unused nitrogen causes environmental damage which is costly to mitigate. The novel technology platform of the project aims to develop new crops with more expansive root systems that use applied nitrogen fertiliser more efficiently and new legume varieties that symbiotically fix more nitrogen in an ecologically-sustainable way.Read moreRead less
Fertility crisis: harnessing the genomic tension behind pollen fertility in sorghum. Hybrid sorghum varieties yield more grain than inbred varieties but the production seed for farmers can be difficult. This project will identify the genes responsible for a trait that makes hybrid seed production possible and this knowledge will help raise sorghum yields in Australian and in some of the world’s poorest countries.
Improving the efficiency of bovine oocyte maturation in vitro. For the dairy and beef industries, the hundreds of eggs (oocytes) in a high value cow's ovary that fail to produce a pregnancy are a wasted genetic resource. A key technology to unlocking this resource is in vitro maturation of oocytes, but the process is inefficient. One possible cause is that the current approaches to maturing oocytes in vitro do not adequately mimic the natural process in vivo. We will design new systems to matu ....Improving the efficiency of bovine oocyte maturation in vitro. For the dairy and beef industries, the hundreds of eggs (oocytes) in a high value cow's ovary that fail to produce a pregnancy are a wasted genetic resource. A key technology to unlocking this resource is in vitro maturation of oocytes, but the process is inefficient. One possible cause is that the current approaches to maturing oocytes in vitro do not adequately mimic the natural process in vivo. We will design new systems to mature cow oocytes in vitro by altering the chemical composition of maturation medium, thus improving the efficiency of laboratory embryo production and related technologies.Read moreRead less
Breeding echidnas in captivity. This project aims to provide novel insights into the cryptic and secretive mode of the reproduction of echidnas, and enable development of reliable methods for breeding them in captivity. There has not been a sustainable breeding program for echidnas in any zoo world-wide. This is needed because most studies on echidnas have all been field-based, and so not open to manipulation to answer key questions relevant to their conservation and survival. Using novel scient ....Breeding echidnas in captivity. This project aims to provide novel insights into the cryptic and secretive mode of the reproduction of echidnas, and enable development of reliable methods for breeding them in captivity. There has not been a sustainable breeding program for echidnas in any zoo world-wide. This is needed because most studies on echidnas have all been field-based, and so not open to manipulation to answer key questions relevant to their conservation and survival. Using novel scientific results on the short-beaked echidna, the project will provide new knowledge relevant to monotreme conservation, research and education, and enable the development of reliable methods for breeding the critically endangered, long-beaked echidna in captivity.Read moreRead less
Chemical inhibition: a new approach to investigate the role of a key protease, CtHtrA, from Chlamydia trachomatis. Infertility in women frequently results from infection with Chlamydia trachomatis. This project will develop an inhibitor compound against a important protein from this bacteria. This will establish a new scientific approach to study Chlamydia trachomatis. This project will also contribute to the development of new treatments for infertility.
Cumulative Harm: Reducing child abuse through improved decision-making. In 2005/06 56,000 cases of child abuse were substantiated in Australia, and this figure is rising exponentially. Disillusionment is growing with an incident based approach to children's safety which fails to either acknowledge or intervene effectively in the cumulative effects of harm to the child's development and well-being. This project uses the leverage of new legislation to re-focus on an earlier intervention with vulne ....Cumulative Harm: Reducing child abuse through improved decision-making. In 2005/06 56,000 cases of child abuse were substantiated in Australia, and this figure is rising exponentially. Disillusionment is growing with an incident based approach to children's safety which fails to either acknowledge or intervene effectively in the cumulative effects of harm to the child's development and well-being. This project uses the leverage of new legislation to re-focus on an earlier intervention with vulnerable children at risk of cumulative harm within a hospital setting. An interdisciplinary lens is bought to the development of new knowledge to provide a better and healthier start to life for this group of children.Read moreRead less
Effectiveness of social skills training for children with autism. Our industry partner, Aspect Australia, is one of the world's largest providers of educational and other services for people with autism. The demonstration of effectiveness of the program in Aspect classes will likely lead to widespread use and benefit of the program in the education sector nationally and internationally. This in turn would lead to potential lessening of disability in children with autism with improvements in thei ....Effectiveness of social skills training for children with autism.

The demonstration of effectiveness of the program in Aspect classes will likely lead to widespread use and benefit of the program in the education sector nationally and internationally. This in turn would lead to potential lessening of disability in children with autism with improvements in their mental health and significant cost savings to the community.Read moreRead less
The tree legume Pongamia pinnata on coal mine spoil: an integrated and sustainable rehabilitation, bioenergy and carbon farming production system. This project aims to assess the growth performance of the tree legume Pongamia pinnata on coal mine overburden. The expected growth of Pongamia on what is regarded as poor quality soil will lead to the development of an integrated production system that will provide benefits through rehabilitation of lands, biofuel feedstock, and carbon farming.
Age at first birth, mode of conception and adjustment to parenthood. The trend to delayed childbearing is well-established, multiply determined and unlikely to change in the short term. This study will provide contemporary Australian evidence on the experience of becoming a parent at different ages, naturally and through assisted conception, for Australian men and women. Both risk and protective factors for older first-time parents will be identified, thus informing policy and services that can ....Age at first birth, mode of conception and adjustment to parenthood. The trend to delayed childbearing is well-established, multiply determined and unlikely to change in the short term. This study will provide contemporary Australian evidence on the experience of becoming a parent at different ages, naturally and through assisted conception, for Australian men and women. Both risk and protective factors for older first-time parents will be identified, thus informing policy and services that can better support Australian families with planning and rearing children. A key outcome will be a Parenting Decision-Aid to provide evidence-based reader-friendly information about the positives and negatives of first-time parenthood at different ages.Read moreRead less
