Summary
The injection of a single sperm into the egg (ICSI) has been the main IVF treatment for men with poor sperm quality since 1993 but is now often used for other types of infertility. Concern has been raised about the health of the children. We will approach >800 parents and their adult sons conceived using ICSI and will assess his general health and development, and fertility. This work will improve patient counselling and practice guidelines, and direct research into the safety of ICSI.
Chromosomes are structures that carry genes in all our cells. Every human cell has 46 chromosomes. In the nucleus of eukaryotic cells, DNA is highly folded and compacted with specific proteins into a dynamic polymer called chromatin. Gene expression, chromosome division, DNA replication, and repair all act, not on DNA alone, but on this chromatin template. The discovery that enzymes can (re)organise chromatin into accessible and inaccessible configurations revealed mechanisms that considerably e ....Chromosomes are structures that carry genes in all our cells. Every human cell has 46 chromosomes. In the nucleus of eukaryotic cells, DNA is highly folded and compacted with specific proteins into a dynamic polymer called chromatin. Gene expression, chromosome division, DNA replication, and repair all act, not on DNA alone, but on this chromatin template. The discovery that enzymes can (re)organise chromatin into accessible and inaccessible configurations revealed mechanisms that considerably extend the information potential of the genetic code. In addition, it is now established that chromatin structural features can influence gene expression. In vitro studies support a model in which chromatin functions as a barrier for the access to DNA. Therefore this organization has to be tighly regulated and dynamic to allow the protein-DNA interactions critical for nuclear functions. Importantly genome organisation provides in addition to genetic information another layer of information, so called epigenetic, which by definition means that it is stably inherited throughout cellular divisions, yet it is not encoded genetically. Thus each cell type will display a specific epigenome. We have recently constructed small human minichromosomes, which are much easier to study than the much larger normal chromosomes. The present project proposes to define the epigenetic feature across an entire human chromosome using our minichhromosomes as working models. The outcome will be a significant gain in our knowledge on the processes underlying epigenetic regulation, the organisation of specialised chromatin domain, and behaviour of the chromosomes.Read moreRead less

This Network brings together researchers within archaeology and environmental sciences to develop cross-disciplinary and internationally comparative approaches to understanding past human responses to rapid environmental change. Integration of skills and perspectives from the Humanities and Sciences will create a generation of scholars able to work across different theoretical frameworks to formulate credible responses to the challenge of creating sustainable societies in a changing world. Through a greater understanding of past societies' reactions to rapid environmental change, the Network will build on existing leading edge research and create a more informed guide to a sustainable future.Read moreRead less
The biology of arbovirus virulence and fitness in arthropod and vertebrate hosts in vivo. In Australia, Ross River virus (RRV) represents significant concern to human health. Between 1992-2005 more than 50,000 notifications of RRV infection have been reported. While not fatal, the disease is responsible for morbidity in the community/individual that can have both social and economic costs. The project has several national benefits. It will help elucidate whether there is any association between ....The biology of arbovirus virulence and fitness in arthropod and vertebrate hosts in vivo. In Australia, Ross River virus (RRV) represents significant concern to human health. Between 1992-2005 more than 50,000 notifications of RRV infection have been reported. While not fatal, the disease is responsible for morbidity in the community/individual that can have both social and economic costs. The project has several national benefits. It will help elucidate whether there is any association between RRV strain and increased risk of RRV transmission and/or occurrence of more severe cases of human disease. It will help develop technologies that can lead towards the identification of viral markers, which could provide new avenues in the design of novel antiviral strategies.

Establishing research programs with Pacific neighbours benefits Australia's relations with Pacific Island countries generally. This project applies novel research methods to understanding human adaptations to long-term environmental and climatic fluctuations. It will address the National Research Priority goal of responding to climate variability by advancing our understanding of recent climate change in the Australia/Pacific region. It will show that Australian researchers can play a significant role in understanding the spread of humans across the Pacific, and the environmental adaptations required by populations in resource depleted environments. It will increase collaboration between research institutions focusing on the Australia/Pacific region.Read moreRead less

This project will enhance our ability to characterise human impact on island biodiversity. It will develop novel research methods that can be applied in the Australian context to understand changes in biodiversity that come with human impact. The contemporary emphasis on biosecurity in the protection of Australia's unique environment against human-introduced exotic pests and diseases can be better understood in the context of past introductions. Our project will demonstrate the role Australian archaeologists and natural scientists can play in understanding the spread of humans across the Pacific and the environmental consequences of colonisation. It will increase collaboration between research institutions in the Australia/Pacific region.Read moreRead less
Role Of SPPL2A On B Cell Survival And Antibody Production In Mice And Humans

Summary
B lymphocytes are a specialised type of blood cells that produce antibodies in response to a pathogen or a vaccine. We have recently discovered that all mature B cells depend for their survival on a previously unknown protein called SPPL2A. This application will investigate the molecular mechanism through which SPPL2A contributes to the survival of B cells. We will also investigate if humans with currently unexplained B cell deficiency have mutations in SPPL2A.

This project aims to address a big challenge in nanophotonics by developing revolutionary methods for efficient chiral sensing of molecules without the need for spectrometry, frequency scanning, or moving mechanical parts, and to enhance chiroptical signals a hundredfold with the help of metasurface structures. Resonant metasurfaces are arrays of engineered dielectric nanoparticles with extraordinary characteristics, and they would allow to overcome current limitations of chiral sensing analytical tools. Detecting chiral molecules in low concentrations is crucially important to many fields of biology, chemistry, and pharmacy, as well as to the food and cosmetics industries, constituting a market of tens of billions of dollars.Read moreRead less
