Small is beautiful: Did gene-rich regions of mammal chromosomes evolve from microchromosomes? Most birds and reptile genomes feature many tiny microchromosomes. These are not junk, as previously thought, but contain most of the genes. Mammals lack microchromosomes, but contain gene-rich regions with similar attributes. We suggest that microchromosomes originated by genome duplication, and evolved into the gene-rich regions of mammalian chromosomes. We will test this hypothesis by comparing seque ....Small is beautiful: Did gene-rich regions of mammal chromosomes evolve from microchromosomes? Most birds and reptile genomes feature many tiny microchromosomes. These are not junk, as previously thought, but contain most of the genes. Mammals lack microchromosomes, but contain gene-rich regions with similar attributes. We suggest that microchromosomes originated by genome duplication, and evolved into the gene-rich regions of mammalian chromosomes. We will test this hypothesis by comparing sequences and genes in microchromosomes of birds, reptiles and monotremes. This will clarify the origin and evolution of the ?microgenome?, establish its suitability as a model for vertebrate genome organisation, and demonstrate whether microchromosomes are the ancestors of the gene-rich regions of mammalian chromosomes.Read moreRead less

Summary
National Facility for Advanced Molecular Orbital Imaging. We will develop a new two-dimensional multiparameter high-resolution electron momentum spectroscopy (EMS) spectrometer that incorporates multiparameter data acquisition and reduction techniques and combine it with a new time of flight (TOF) ion-analyser in order to perform the first high-resolution EMS with oriented target experiments.
In conjunction with theoretical calculations, the results from these experiments will provide the most ....National Facility for Advanced Molecular Orbital Imaging. We will develop a new two-dimensional multiparameter high-resolution electron momentum spectroscopy (EMS) spectrometer that incorporates multiparameter data acquisition and reduction techniques and combine it with a new time of flight (TOF) ion-analyser in order to perform the first high-resolution EMS with oriented target experiments.
In conjunction with theoretical calculations, the results from these experiments will provide the most advanced evaluation for molecular orbital imaging quality for the chemically significant targets we wish to study. This in turn will lead to the determination of more accurate physico-chemical information, including structure and bonding information, for these targets.Read moreRead less
Solving the Mysteries of Monotreme Chromosomes. The peculiar chromosomes of Australia's platypus and echidna have been debated for more than 30 years. Classical cytology cannot resolve the puzzling sex chromosome system, or to sort out the bizarre translocation chain (unique in vertebrates) and deduce how it segregates to make viable zyotes. I will microdissect individual chromosomes, and use DNA ?paints? from them (and gene probes isolated by them) to detect homologies between unpaired chromoso ....Solving the Mysteries of Monotreme Chromosomes. The peculiar chromosomes of Australia's platypus and echidna have been debated for more than 30 years. Classical cytology cannot resolve the puzzling sex chromosome system, or to sort out the bizarre translocation chain (unique in vertebrates) and deduce how it segregates to make viable zyotes. I will microdissect individual chromosomes, and use DNA ?paints? from them (and gene probes isolated by them) to detect homologies between unpaired chromosomes at mitosis, meiosis and in sperm. I will use immunohistochemistry to clarify chromosome pairing and recombination at meiosis. This will answer some important general questions about chromosome behaviour and sex chromosome evolution.

Environmental and Technological Applications of Electron-Driven Processes. We plan to use state-of-the-art experimental techniques and methodologies for the measurement of collision cross sections and reaction rates for low energy electron-driven process in molecules and molecular radicals. These processes are fundamental to our understanding of our environment and many devices used in the technology of today and of the future. In particular we will provide accurate cross sections for NOx and SO ....Environmental and Technological Applications of Electron-Driven Processes. We plan to use state-of-the-art experimental techniques and methodologies for the measurement of collision cross sections and reaction rates for low energy electron-driven process in molecules and molecular radicals. These processes are fundamental to our understanding of our environment and many devices used in the technology of today and of the future. In particular we will provide accurate cross sections for NOx and SOx pollutants and H2O, as well for molecules such as C4F8, and its radicals such as CF2, which are used extensively in plasma processing technologies.Read moreRead less

This project aims to improve the rights and wellbeing of young people with cognitive disability by exploring their relationship and interaction with paid support workers. The introduction of national individualised funding and support is a watershed in Australian disability policy. Understanding the role that paid support plays in the ongoing identity development of these young people is urgently needed to realise national policy aspirations for people with disability of rights, choice, inclusion and independence. Using social geography and recognition theory, the project expects to deliver new understanding and improved practice around how paid support relationships can foster mutual care, respect and value at a critically important time in young people’s lives.Read moreRead less
ARC Centre of Excellence - Centre for Antimatter-Matter Studies. While our world is made of matter, all particles have anti-particles and the most abundant is the positron, the electron's antiparticle. It is the "workshop" for most anti-matter studies, particularly for the characterization of materials, including gases, polymers, insulators, thin films and surfaces, as well as the development of new and novel, nano-structured materials.

The ARC Centre of Excellence in Antimatter-Matter Studies (CAMS) will bring together key Australian and international scientists to work in this emerging scientific field of antimatter-matter interactions. It will forge a unique and effective scientific team for state-of-the-art studies of the nano-world that underlies many everyday processes and new technologies.Read moreRead less
The origins of electroreception and nocturnality in the earliest known jawed vertebrates and their bearing on vertebrate diversification.

This project aims to discover primary new data to pinpoint the timing, anatomical origins and phylogenetic significance when two key sensory systems first appeared in modern vertebrates: electroreception and specialised nocturnal vision. Such abilities today allow high diversity of vertebrates to co-exist within the same geographical range, for example on tropical reefs or rainforest communities, through careful temporal niche partitioning where reliance on other sensory systems takes over from vision and olfaction as the principal method of prey detection. This project aims to elucidate how the modern fish diversity was shaped by such significant early evolutionary events.Read moreRead less

Trust makers, breakers and brokers: building trust in the Australian food system. This research will compare and contrast the way that food trust is managed in Australia and the United Kingdom, with a particular focus on how trust is damaged and repaired. Using consensus-testing processes, best practice models will be developed to assist government, industry, media and consumer groups to build and maintain trust in the food supply.
