Summary
14% of Australian children develop mental health problems. As treatment is time and cost intensive, prevention is the ideal model. This can be targeted to ‘at risk’ children, but may stigmatise families and have poor uptake. This project aims to trial whether a population targeted approach embedded in universal prevention performs better than targeted prevention alone, with each approach compared to ‘usual care’. The local and state government partners will ensure sustainability, policy relevanc ....14% of Australian children develop mental health problems.

Summary
Adolescence is a risk period for the emergence of psychiatric disorders. It is also a time of rapid change in the brain, but few studies have detailed changes in neurodevelopment during this sensitive period. We will study twins from early adolescence and use brain imaging to investigate changing brain patterns as the brain matures, and thereby, gain insight into factors responsible for increasing our risk or resilience for major mental health conditions and optimal points for intervention.
Mobile DNA activity in the mammalian primordial germline. Early in pregnancy, a handful of cells in the embryo become primordial germ cells (PGCs). These PGCs will eventually give rise to sperm or egg cells, representing a critical inter-generational genetic link. Mobile DNA sequences target PGCs to create new heritable genetic changes. This proposal aims to analyse the activity, regulation, and consequences of mobile DNA activity in PGCs.

Early in pregnancy, a handful of cells in the embryo become primordial germ cells (PGCs). These PGCs will eventually give rise to sperm or egg cells, representing a critical inter-generational genetic link. Mobile DNA sequences target PGCs to create new heritable genetic changes. This proposal aims to analyse the activity, regulation, and consequences of mobile DNA activity in PGCs. This project expects to generate significant knowledge about the origins of mammalian genetic diversity. Expected outcomes include enhanced national and international collaborations across disciplines and new experimental systems. The expected benefit is an enhanced understanding of the mutational processes underlying genetic diversity and disease in mammals.Read moreRead less
This study investigates how much an individual's genes and environment account for the wide variation in brain structure and function. Using brain imaging we examine in what way the connectivity of the brain of identical and non-identical twins is the same or different from that of their co-twin, and carry out analysis of their DNA to identify some of the genes involved. This will provide fundamental information on genetic mechanisms influencing variation in brain structure and function.
Determining principles for successful episode retrieval of repeated events. This project aims to develop the first-ever set of explanatory principles for how people successfully retain and retrieve individual episode memories from repeated experiences (e.g., one occurrence of a routine social encounter or job-related activity). By deepening our understanding of how memory works, this new knowledge is expected to lay the foundation for interview guidance and ongoing research aimed at enhancing th ....Determining principles for successful episode retrieval of repeated events. This project aims to develop the first-ever set of explanatory principles for how people successfully retain and retrieve individual episode memories from repeated experiences (e.g., one occurrence of a routine social encounter or job-related activity). By deepening our understanding of how memory works, this new knowledge is expected to lay the foundation for interview guidance and ongoing research aimed at enhancing the proficiency of investigations into matters that rely on detailed and accurate accounts of specific episodes. This includes workplace or traffic accident investigations, infectious disease contact tracing, as well as prosecution of repeated sexual offences.Read moreRead less
Foundations of a good egg: correctly transitioning from mitosis to meiosis. Production of viable offspring is essential to the survival of any species. In all sexually reproducing species, this requires a unique cell type, the germ cell. Germ cells undergo a special type of cell division, called meiosis, so that they can eventually produce gametes (sperm in males and eggs in females). This project aims to discover how germ cells halt the standard form of cell division, called mitosis, and initia ....Foundations of a good egg: correctly transitioning from mitosis to meiosis. Production of viable offspring is essential to the survival of any species. In all sexually reproducing species, this requires a unique cell type, the germ cell. Germ cells undergo a special type of cell division, called meiosis, so that they can eventually produce gametes (sperm in males and eggs in females). This project aims to discover how germ cells halt the standard form of cell division, called mitosis, and initiate meiotic division instead. It is important to understand all the fundamental processes that occur during normal germ cell development so that, in the future, we can use this knowledge to support agricultural advances, rescue endangered species and solve human problems such as infertility and genetic disease.Read moreRead less
Understanding How Language And Reading Problems Develop: A Population-based Longitudinal Study From Infancy To Age 7

Summary
Early language and reading problems are common and therefore significant public health problems. They are disabling and have life-long implications for oral and written communication skills, social and emotional well-being, cognition, behaviour, academic achievement and employment. This study will address the following three problems: 1. To date no study has documented how language and reading problems develop from infancy (8 months) through to school age (7 years). 2.

They are disabling and have life-long implications for oral and written communication skills, social and emotional well-being, cognition, behaviour, academic achievement and employment. This study will address the following three problems: 1. To date no study has documented how language and reading problems develop from infancy (8 months) through to school age (7 years). 2. Little is known about risk factors, identified early in infancy and childhood, that can be reliably used to predict language and reading problems later in childhood. 3. The relationships between language difficulties and reading problems are poorly understood. Therefore, we currently have no satisfactory methods for reliably detecting which children at much younger ages are at risk of later language disorders or reading problems. Without this information it is impossible to develop effective prevention and early intervention programs. These programs are critical if we are to: a) Prevent language and reading problems from occurring, thereby reducing the prevalence of the problem b) Intervene early in childhood, thereby reducing in the longer term the burden and cost associated with language and reading problems. The proposed study builds on an existing substantial investment by the NHMRC in the Early Language in Victoria Study (ELVS). It will provide a world-first description of the evolution of language difficulties and reading problems from infancy through to school age within a single population cohort.Read moreRead less
Morphological development of the kidney – a paradigm for organogenesis. This project aims to shed new light on how the kidney develops, how normal adult function is established and how congenital kidney malformations occur.

This project aims to shed new light on how the kidney develops, how normal adult function is established and how congenital kidney malformations occur. It aims to investigate a mathematical pattern that has been discovered in the program of branching morphogenesis which dictates kidney development. By combining cutting-edge genetic approaches, morphological analysis and mathematical modelling, this project plans to explore how this pattern is established, how it dictates kidney development and whether it constitutes an ancient mechanism central to organ formation. Project outcomes may improve understanding of fundamental developmental processes and developmental disease and variation. Project findings may also be important for understanding the development of other organ systems.Read moreRead less

But how do we best facilitate this where it’s culturally appropriate or encourage innovation to support more general learning? This developmental psychology project aims to provide answers, using novel experiments and comparisons of different cultural groups to show how children acquire skills while becoming valued community members. Expected outcomes include the refinement of core developmental psychology theory, introduction of new experimental techniques, and strengthening of international collaborations. This should provide significant benefits to educators, policy makers, parents and those invested in understanding and improving the inter-generational transmission of knowledge.Read moreRead less
