Who were the ancestors of Homo floresiensis? The discovery of a tiny, new hominid species living in Indonesia until just 12,000 years ago, at the same time as modern humans in the region, has sparked world-wide public interest and debate. Finding the ancestors of this species will further promote Australian research as high profile, high calibre and cutting edge. Collaboration with researchers and institutions in Indonesia, USA, Kenya, Tanzania, South Africa and the Republic of Georgia will stre ....Who were the ancestors of Homo floresiensis?

How beetles harness near-infrared properties to enhance energy efficiency. This project aims to discover how animals use nanophotonic structures to manipulate near infra-red light for thermal control and visual information. Almost nothing is currently known about the mechanism, function and evolution of near-infrared properties in animals, despite their potential importance for maintaining body temperatures within the critical thermal limits for survival.

This project aims to discover how animals use nanophotonic structures to manipulate near infra-red light for thermal control and visual information. Almost nothing is currently known about the mechanism, function and evolution of near-infrared properties in animals, despite their potential importance for maintaining body temperatures within the critical thermal limits for survival. The project uses multidisciplinary techniques from optical physics, physiology and evolutionary biology to reveal near-infrared adaptations in socially and economically important Christmas beetles. The intended outcomes include a bio-informed blueprint for a new class of functional nanomaterials that enhance energy efficiency.Read moreRead less
Alternative Splicing in the Mouse Transcriptome. Although the human genome completion is cause for excitement we do not have any firm indication of precisely how many protein-coding genes exist in a mammalian genome. We have even less indication of the extent to which these genes generate alternative gene products, through a process termed alternative splicing. The detection and sequencing of these full-length alternative gene products is the focus of this application. This application details t ....Alternative Splicing in the Mouse Transcriptome.

SCP/TAPS proteins of the barber’s pole worm. This integrated, collaborative project, will explore, in a targeted way, the structure and function of a key group of molecules in a socio-economically important eukaryotic pathogen and their involvement in pathogen-host interactions. Fundamental knowledge and understanding of these molecules will provide a solid foundation for understanding disease processes and finding new intervention strategies for a range of pathogens.

Fundamental knowledge and understanding of these molecules will provide a solid foundation for understanding disease processes and finding new intervention strategies for a range of pathogens. This is crucial, given the serious drug resistance problems in pathogens, and residue problems in meat, milk and the environment.Read moreRead less
Nature’s advanced optical materials and their role in thermal management. This project aims to discover the nano-structural properties of beetles than enable effective management of solar and thermal radiation in different environments. A further aim is to reveal how these composite biological materials combine thermal control with desirable mechanical properties, such as strength and flexibility.

This project aims to discover the nano-structural properties of beetles than enable effective management of solar and thermal radiation in different environments. A further aim is to reveal how these composite biological materials combine thermal control with desirable mechanical properties, such as strength and flexibility. Passive control of radiative energy is critical for both animal survival and for the design of many manufactured materials, particularly in a warming world. This interdisciplinary project will provide new knowledge of the different ways that biological materials mediate radiative energy exchange with the environment. This knowledge is essential for the design of bioinspired, energy-efficient, multi-functional materials.Read moreRead less
Infrakingdom Alveolata: searching for a defining structural feature. This project will establish the first molecular nexus between a cellular structure currently used to define an Infrakingdom of life. It will aid in the higher order systematics of our microscopic diversity and allow us to interpret how important parasites learned to penetrate host cells to establish infection. We will train excellent graduate and Honours students in cellular and molecular biology.
How calcium makes the heart grow. This project aims to develop a mathematical model of calcium signalling in heart cells to understand how calcium makes the heart grow. Our hearts grow to adapt to long-term changes, such as during development and in pregnancy or heart disease. Biochemical reactions involving calcium control the growth of heart cells and heart cells also use calcium signalling to trigger contraction with each beat. How calcium controls the heartbeat and regulates cell growth is u ....How calcium makes the heart grow. This project aims to develop a mathematical model of calcium signalling in heart cells to understand how calcium makes the heart grow. Our hearts grow to adapt to long-term changes, such as during development and in pregnancy or heart disease. Biochemical reactions involving calcium control the growth of heart cells and heart cells also use calcium signalling to trigger contraction with each beat. How calcium controls the heartbeat and regulates cell growth is unknown. This project will develop a new mathematical model of calcium signalling in heart cells to understand important cellular adaption processes. This knowledge will lead to the ability to independently control cellular pathways mediated by calcium, opening new avenues in biotechnology and biomedicine.Read moreRead less
Mathematical models and bioinformatic analyses of bacterial genome evolution. Bacteria are vital agents in earth's biosphere, breaking down and synthesising a wide variety of compounds. Some bacteria cause disease; others are exploited for a range of biotechnological applications. Bacteria have a remarkable ability to survive and thrive in changing conditions. For example, pathogenic bacteria confronted by antibiotics easily evolve resistance to them. With the reality of climate change, we expec ....Mathematical models and bioinformatic analyses of bacterial genome evolution. Bacteria are vital agents in earth's biosphere, breaking down and synthesising a wide variety of compounds. Some bacteria cause disease; others are exploited for a range of biotechnological applications. Bacteria have a remarkable ability to survive and thrive in changing conditions. For example, pathogenic bacteria confronted by antibiotics easily evolve resistance to them. With the reality of climate change, we expect more rapid shifts in the structure of bacterial communities, possibly leading to the emergence of new pathogens. The benefits of this project are to discover how the genetic structure of bacteria confer this flexibility, and to help keep Australia at the forefront of research in bioinformatics and mathematical biology.

This research aims to use forefront molecular microbiology and biophysical approaches to advance fundamental knowledge on bacterial biofilms. These bacterial clusters are held together by an extracellular matrix comprised of bacterial-derived fibrous protein and the polysaccharide cellulose, which imparts structural integrity and resistance to antimicrobials. The major goals of this project are to dissect how bacteria regulate production of the biofilm matrix, and examine how changes in the composition of the matrix alters its properties, including the penetration of antimicrobial peptides and antibiotics. The outcomes will help address the economic burden of difficult to treat industrial, environmental and biomedical biofilms.Read moreRead less
