Summary
Does spurious maternal-fetal signalling support the evolution of a placenta. This project aims to test a model that explains how the placenta has evolved as a new organ more than 100 times in fishes, reptiles, and mammals including our own ancestors. The project will assess whether regulatory components of the placenta evolve as a result of spurious maternal-fetal signalling following egg retention and eggshell loss in viviparous reptiles. Expected outcomes of this project include a new understa ....Does spurious maternal-fetal signalling support the evolution of a placenta. This project aims to test a model that explains how the placenta has evolved as a new organ more than 100 times in fishes, reptiles, and mammals including our own ancestors. The project will assess whether regulatory components of the placenta evolve as a result of spurious maternal-fetal signalling following egg retention and eggshell loss in viviparous reptiles. Expected outcomes of this project include a new understanding of how complex organs originate and evolve in animals. This will benefit society through a broader depth of understanding of our own evolutionary history and provides a framework for future studies to investigate the origin and evolution of organs more broadly in animals.Read moreRead less
Old genes learning new tricks: characterising regulatory changes driving increased heart complexity during vertebrate evolution. The heart has dramatically increased in morphological complexity during vertebrate evolution but the molecular basis driving these major changes remains unknown. Using comparative genomics approaches, this project will explore changes in the regulation of genes involved in heart formation that lead to changes in cardiac structure. It will elucidate for the first time t ....Old genes learning new tricks: characterising regulatory changes driving increased heart complexity during vertebrate evolution. The heart has dramatically increased in morphological complexity during vertebrate evolution but the molecular basis driving these major changes remains unknown. Using comparative genomics approaches, this project will explore changes in the regulation of genes involved in heart formation that lead to changes in cardiac structure. It will elucidate for the first time the cardiac regulatory repertoire in zebrafish and will compare it with that of fly and mouse using cutting-edge bioinformatics pipelines. This work will unravel cardiac-specific regulatory modifications that give rise to evolutionary changes. On a broader scale, it will shed new light on the role of regulatory innovations over gene innovations in the emergence of new traits.Read moreRead less
The Burden Of Late Preterm Birth On Brain Development And 2 Year Outcomes – A Prospective, Longitudinal Cohort Study

Summary
80% of preterm babies are born from 32-36 weeks’ gestation, and are late preterm (LPT). LPT children have more learning problems, but why this occurs is unknown. This study aims to understand the effect of LPT birth on brain development. We will do brain scans at term and assess development at 2 years of age of 200 LPT and 200 full-term children. We expect LPT babies will have subtle alterations in brain development compared with term controls which will be associated with delayed development.
Motor problems, ranging from clumsiness to cerebral palsy, are one of the most common adverse outcomes in children born early. This study will investigate the motor development of children born <30 weeks’ gestation compared with peers born at term from birth to 5 years. We will determine whether early clinical evaluations or neuroimaging in the newborn period can predict later motor impairment at 5 years to be able to identify those who will benefit most from early intervention.
Social outcomes, behaviour and emotional well-being of adults with autism. It is recognised that autism results in substantial life-long disability. Severe emotional and behavioural problems are likely to be a key factor in precluding adults with autism from work, independent living, social contact, and undermine their quality of life, thus increasing support needs. This project aims to address a major gap in our current knowledge - the association between severe emotional and behavioural proble ....Social outcomes, behaviour and emotional well-being of adults with autism. It is recognised that autism results in substantial life-long disability. Severe emotional and behavioural problems are likely to be a key factor in precluding adults with autism from work, independent living, social contact, and undermine their quality of life, thus increasing support needs. This project aims to address a major gap in our current knowledge - the association between severe emotional and behavioural problems in adults with autism and social outcomes. Identification of markers of adult outcomes aims to lead to an improved understanding of the pathways to better social outcomes, facilitating the development of specific interventions to provide much needed improvements in outcomes for adults with autism.Read moreRead less
Discovering sources of individual differences in first language acquisition. This project aims to investigate the processes of language acquisition to support the development of evidence-based strategies for improving children's early language. Some children learn language earlier and more easily than others. Understanding why this is the case is important because successful acquisition is strongly associated with positive life outcomes such as academic achievement and psychological wellbeing.

This project aims to investigate the processes of language acquisition to support the development of evidence-based strategies for improving children's early language. Some children learn language earlier and more easily than others. Understanding why this is the case is important because successful acquisition is strongly associated with positive life outcomes such as academic achievement and psychological wellbeing. This project focuses on typically developing children, investigating how their ability to detect frequently occurring patterns in the environment significantly contributes to their acquisition of grammar in early childhood. The project plans to use an innovative triangulation of experimental methods from developmental psychology, longitudinal analysis and cognitive modelling to drive the development of new models of language acquisition and transform our understanding of both typical and atypical acquisition.Read moreRead less
Do theory of mind delays explain children's social problems? Theory of mind—our capacity to understand what other people think and feel—grows significantly in the preschool and early school years. This is recognised as a crucial period for social development yet 30 years of research has not yet answered these basic questions: Do children with relatively advanced theories of mind also excel at navigating the everyday world of friendship and peer group dynamics at school? And conversely, do develo ....Do theory of mind delays explain children's social problems? Theory of mind—our capacity to understand what other people think and feel—grows significantly in the preschool and early school years. This is recognised as a crucial period for social development yet 30 years of research has not yet answered these basic questions: Do children with relatively advanced theories of mind also excel at navigating the everyday world of friendship and peer group dynamics at school? And conversely, do developmental delays in acquiring a theory of mind explain some of the peer problems that children with autism or deafness face? The proposed longitudinal project aims to be the first to supply a comprehensive and causally convincing answer to these core questions.Read moreRead less
Heads or tails - which did echinoderms lose in the evolution of radial symmetry? Echinoderms, despite their unusual radial body plan, are closely related to chordates, but it is not known how this plan evolved. This project uses gene expression studies with uniquely suited Australian species to identify genes involved in radial body plan development and generate insights into origins of chordates and the vertebrate central nervous system (CNS).
Relocation after parental separation: a longitudinal study. This project is to examine the long-term outcomes of relocation disputes, when one parent after separation wants to move far away with the children against the opposition of the other parent. The study is of great international importance, as these disputes have become so numerous and difficult to resolve. The results of the study will enhance Australia's international reputation as a leader in family law innovation and research. The na ....Relocation after parental separation: a longitudinal study.

The study is of great international importance, as these disputes have become so numerous and difficult to resolve. The results of the study will enhance Australia's international reputation as a leader in family law innovation and research. The national benefits will include better information for courts in making relocation decisions and an evidence-base for the Government to make legislative changes if needed.Read moreRead less
