Planetary systems like our own form within vast disks of primordial gas and dust around newborn stars. This project will observe such disks spanning a range of ages with the James Webb Space Telescope to reveal the detailed in-situ physics of planet-forming disks themselves. We will deliver the sharpest-ever infrared images in astronomy, exploiting the only Australian-designed instrument on the spacecraft: the Aperture Masking Interferometer. This yields new physics for actively growing protoplanets, carved rings and gaps in disks, and gravitationally sculpted patterns of leftover cometary debris. Confronting state-of-the-art models with these data will immediately yield profound insights into planetary system formation, including our own.Read moreRead less
Comprehensive Assessment Of Genetic And Environmental Risk Factors For Melanoma: A Population-based Family Study

Summary
Excessive sunlight can cause melanoma, a serious type of skin cancer. However, there are other factors including a person's genetic make-up that are thought to put some people at higher risk. Many 'healthy' people have small changes in their genes that might make them more likely to develop melanoma. We need to know more about these genetic factors. Our study will investigate how particular small genetic changes influence a person's likelihood of developing melanoma.
Redefining the immune landscape of the human ocular surface. At the ocular surface, the cornea and limbus need to mount effective immune responses to maintain corneal transparency for clear vision. The current paradigm is that the human cornea houses the same innate immune cell subsets (dendritic cells and macrophages) as naïve mice in pathogen-free facilities. Our pilot data challenge this premise, with early evidence that innate and adaptive cells (T cells) coexist in normal human corneas.

At the ocular surface, the cornea and limbus need to mount effective immune responses to maintain corneal transparency for clear vision. The current paradigm is that the human cornea houses the same innate immune cell subsets (dendritic cells and macrophages) as naïve mice in pathogen-free facilities. Our pilot data challenge this premise, with early evidence that innate and adaptive cells (T cells) coexist in normal human corneas. Integrating state-of-the-art techniques, we will advance understanding of immune regulation at the human ocular surface by comprehensively defining immune cell biology and dynamics. We will define the effect of age on immune cells in these tissues, and relationships between the tear proteome and cell behaviours.Read moreRead less

Summary
Despite 100 years of research there is uncertainty about effects of low dose radiation from background and medical X-rays. We will measure the incidence of cancer in Australians exposed to CT scans (medical X-rays) as children between 1985 and 2005. Our results, from follow-up to 2009, will show whether there is a small but signicantly increased risk of cancer and guide further improvement in radiation safety standards if these prove to be necessary.
Ultrafast tracking of physiological processes in the human eye. Recent developments in high-resolution imaging allow individual cells in the living eye to be studied at very high speeds. This project aims to explore a new class of scientific observations of rapid phenomena including: the capture and conversion of light energy to electrical energy, the spread of pressure waves through delicate networks of blood vessels, and fast eye movements used to navigate the visual scene.

Recent developments in high-resolution imaging allow individual cells in the living eye to be studied at very high speeds. This project aims to explore a new class of scientific observations of rapid phenomena including: the capture and conversion of light energy to electrical energy, the spread of pressure waves through delicate networks of blood vessels, and fast eye movements used to navigate the visual scene. This project expects to generate new knowledge about these processes using state of the art technology, to reveal more about how the eye and visual system work. Our novel measures of physiological function will offer significant future benefit in the early diagnosis and treatment of disorders occurring at the cellular level.Read moreRead less

Summary
Epilepsy is the most common serious brain condition. Seizures affect about 10% of people at some time in their life and their consequences are an important public health problem. The most common group of inherited epilepsies account for about 30% of childhood epilepsy and 20% of adult epilepsy. This study will be the first in Australia and one of only a few worldwide to take a population-based approach to investigating the link between epilepsy and genetic inheritance.

Summary
Despite the considerable advances in the diagnosis and treatment of group A streptococcal (GAS) diseases made during the last century, the impressive spectrum of infections caused by this organism continues to have a significant impact in developed countries. This spectrum includes diseases that are mild but common (e.g. sore throat, skin sores), rare but very severe (e.g. bloodstream infections, flesh-eating bacteria) and those that are more common in developing countries and the Aboriginal pop ....Despite the considerable advances in the diagnosis and treatment of group A streptococcal (GAS) diseases made during the last century, the impressive spectrum of infections caused by this organism continues to have a significant impact in developed countries. This spectrum includes diseases that are mild but common (e.g. sore throat, skin sores), rare but very severe (e.g. bloodstream infections, flesh-eating bacteria) and those that are more common in developing countries and the Aboriginal population (e.g. rheumatic fever, kidney disease). Streptococcal sore throat remains one of the most common childhood infections, and severe group A streptococcal diseases are thought to be increasing in incidence in Australia. Yet, there are no accurate data on the incidence and costs of these or other GAS diseases in non-Aboriginal Australians, or in most other populations around the world. It is becoming more urgent to collect this data as numerous vaccine candidates are entering human trials, new approaches to the treatment of sore throat are emerging, and new strategies to treat and control the spread of severe disease are being developed. We propose a comprehensive strategy to measure the incidence, prevalence and costs of each group of GAS diseases. We will follow a group of families for 12 months to detect cases of GAS sore throat and skin sores and measure the impact on the family. We will survey children in schools to estimate the prevalence of skin sores. We will check hospital records to calculate the number of cases of rheumatic fever and kidney disease. And we will maintain surveillance for severe diseases by checking hospital and laboratory records. We will also check to see if family members of people with severe disease have the GAS bacterium in their throats. We will then compile these data into a comprehensive estimate of the burden of disease in Victoria, and estimate the cost-effectiveness of different treatment and prevention strategies.Read moreRead less

Summary
We have recently completed a study examining the prevalence of birth defects in assisted conception infants born in Western Australia from 1993-1997. Contrary to reassuring claims by other researchers in this area, we found that assisted conception infants have a two-fold increased risk of being diagnosed with a major birth defect by one year of age.

Contrary to reassuring claims by other researchers in this area, we found that assisted conception infants have a two-fold increased risk of being diagnosed with a major birth defect by one year of age. We now propose to examine other long-term health outcomes in these children. This study involves record linkage between the WA Reproductive Technology Register and four other population-based databases. The prevalence of cerebral palsy, intellectual disability, hospital admission and birth defects in assisted conception children born in WA between 1993 and 2001 will be compared to that seen in all other Western Australian children born over the same time period. The collection of information on risks associated with assisted conception treatment is vital to allow adequate counselling of couples considering fertility treatment. Cerebral palsy, intellectual disability, birth defects and hospital admission are all serious adverse health outcomes and, despite the introduction of IVF to most Western countries twenty years ago, there are limited data in the literature concerning the occurrence of these conditions in assisted conception infants. Quantifying the contribution of assisted conception treatment to neonatal, infant and childhood morbidity and mortality is also important for the planning of health service provision. Although assisted conception births represent only a small proportion of total births in Australia, these infants may require a disproportionate level of health care services, such as neonatal intensive care treatment due to complications associated with preterm or multiple birth. The wide application of assisted conception treatment in Australia and the increased number of pregnancies achieved by these means reinforce the urgent need for valid data on the health of children born after these procedures.Read moreRead less

This project capitalizes on two existing large-scale studies, to increase our scientific understanding of strategies for maintaining the health and wellbeing of older people living in the community. Two separate longitudinal research projects, the Australian Longitudinal Study on Women’s Health involving over 12,000 older women selected from every part of Australia, and the Health in Men Study involving over 12,000 older men from Perth, Western Australia, have been following older Australians in order to determine what contributes to older people’s health and quality of life. The new project will combine data from these two studies. The two projects contain a breadth of data and can address the following questions: What health-related, personal, lifestyle and social factors predict survival and healthy non-disabled life in men and women aged 70-90 years? Do changes in lifestyle in older age (eg smoking cessation) affect length and quality of life? Who makes greatest use of health services, and who least, and how does this relate to health outcomes?How are health and lifestyle factors related to social connectedness and independent living in older age? What health and lifestyle factors predict positive mental health in older age? How are older men’s and women’s lifestyles and health status different, and how are they the same? Should health promotion programs in old age target men and women separately, or not?Read moreRead less
