Summary
We all began life with a set of genes inherited from our parents. However, it's now known that from the time we were in the womb onwards that genes can be turned off and on by the environment or even completely lost or gained. Even what your mother ate or how she behaved while she was pregnant could have influenced your future health. Because people are so different, we are studying the subtle differences between twins to tease out the factors that may influence our genes and our health.

Summary
The DNA in each of our cells does not exist alone, it is packaged into complex structures called chromosomes, through association with many different proteins. The distribution of these proteins varies along the length of a chromosome depending on the type of cell and this phenomenon is called 'epigenetics', literally meaning 'above the DNA'. Epigenetic analysis is the study of how proteins and other molecules can change the activity of a gene without changing the DNA sequence. All of our cells ....The DNA in each of our cells does not exist alone, it is packaged into complex structures called chromosomes, through association with many different proteins. The distribution of these proteins varies along the length of a chromosome depending on the type of cell and this phenomenon is called 'epigenetics', literally meaning 'above the DNA'. Epigenetic analysis is the study of how proteins and other molecules can change the activity of a gene without changing the DNA sequence. All of our cells use epigenetic changes to help control how they grow and develop. Evidence suggests a direct link between diet and environmental influences on our epigenetic profile. Recent research has traced the origins of many of the health problems of adult life back to the earliest periods of development _ to the time spent in the womb and the first few years of life. If we are born with a low birth weight, we are more likely to get sick later in life. Overwhelming evidence exists that the environment in the womb is critical for a healthy birth weight (and health in later life) and it is thought that epigenetics may be the missing link between this environment, low birth weight, and therefore health in later life. In addition, mounting evidence supports a general link between epigenetic de-regulation and predisposition to disease. However, the timing and the overall contribution of environmental- genetic influences to the establishment of faulty epigenetic markings remain largely unknown. Twins are the best model to study this link as they share similar (but not identical environments) and some share identical genetic makeup. Using twins, Dr Jeffrey Craig and his team will investigate the factors in the prenatal environment that modify specific cells, leading to low birth weight and increase disease risk later in life. They predict that this occurs via specific changes in gene activity caused by epigenetic disruption.Read moreRead less
Epigenetic Programming Of Immune Development In Utero: Role Of The Maternal Environment In The Allergy Epidemic

Summary
This study will provide new insights into the development of allergic disease. Specifically, we will explore the hypothesis that allergic disease and other disorders or immune dysregulation occur as a result of gene-environmental interactions in early life, and that these events begin in pregnancy when the developing fetus is still developing and most susceptible to these effects.

Migration management in the Mekong. The project seeks to examine the claims that new policy models make about assuring the safety of labour migrants. What is safe about safe migration? Regulation of labour migrants is a central policy concern in Asia, Australia and elsewhere. In an attempt to address anti-trafficking, several donors, United Nations agencies, nongovernment organisations and Governments have launched ‘safe migration’ programs which, rather than focusing solely on the legal status of migrants, seek to develop mechanisms (eg hotline numbers) to assure their safety. This research examines the claims of safety that this shift from anti-trafficking to safe migration has engendered, and whether and in what terms labour migrants might be consequently safer’. Project results may inform aid programs and government policies.Read moreRead less
Intercultural understanding in primary and secondary schools. What facilitates or impedes intercultural understanding in children, adolescents and schools? How can this be addressed? How can we know what makes a difference? This project answers these questions at the individual, school and national level using a novel cultural systems approach and methodological and technological innovations.

Summary
Attention deficit hyperactivity disorder –combined type (ADHD-CT) is a complex neuropsychiatric disorder with a progressively devastating impact on psychosocial development. The first objective of this study is to use 3D-motion analysis to ‘probe’ the underlying brain dysfunction which characterises ADHD-CT. The second objective of this study is to improve our understanding of the link between movement problems, and (a) injury proneness, and (b) social-communicative problems, in children with AD ....Attention deficit hyperactivity disorder –combined type (ADHD-CT) is a complex neuropsychiatric disorder with a progressively devastating impact on psychosocial development.

Taming the intruders: the domestication of Tigger transposable elements in mammals. It has become apparent that most of the DNA that makes us what we are is actually comprised of the remnants of invading parasitic DNA acquired over time.

A continual battle exists between host which tries to silence or remove this DNA, and the parasite that tries to multiply and spread. We are currently investigating an intriguing aspect of this process that involves host genomes 'domesticating' parasitic DNA to provide novel functions, thereby facilitating the evolution of specific characteristics within species.Read moreRead less

Current evidence suggests child and youth participation in matters affecting their lives has many benefits, but little is known about how this is perceived and practiced in education. This research aims to improve knowledge about processes and outcomes of student participation at school, particularly in relation to improving wellbeing. The project is timely and significant because recent reforms in education now require a greater emphasis on engaging students more directly in decisions about their education, including those with special needs. Schools urgently require knowledge about the key elements of participation that impact on wellbeing and a tool for measuring and monitoring their performance in facilitating these elements.Read moreRead less

Canada and Australia have had the world's highest immigration rates in recent decades. Central to the success of an immigration programme is the level of integration on immigrants themselves but, more importantly, their children. Australian research has led the world in this field. However, there is much to be gained for the mutual benefit of both countries through comparative research using a common framework. More broadly, as demography takes on much greater significance with population aging, there is much to be gained through international cooperation between ANU Demography and Canada's leading centre for demography, the University of Montreal.Read moreRead less
