Aerosol glassy states promote global warming, airborne toxins and pathogens. This project will improve our understanding of the role played by airborne particles in global climate, pollution and the transmission of influenza, corona virus and the common cold. It will do so by revealing the wider importance of "glassy states" of matter recently revealed in atmospheric aerosols. Glassy states are highly unpredictable quasi solids that abruptly form, interrupting the transition of a liquid to a sol ....Aerosol glassy states promote global warming, airborne toxins and pathogens. This project will improve our understanding of the role played by airborne particles in global climate, pollution and the transmission of influenza, corona virus and the common cold. It will do so by revealing the wider importance of "glassy states" of matter recently revealed in atmospheric aerosols. Glassy states are highly unpredictable quasi solids that abruptly form, interrupting the transition of a liquid to a solid. This interruption invalidates equilibrium assumptions of models of droplets as cloud nuclei and infection vectors. We will develop and validate a numerical tool for predicting glassy state formation and its impact in broad classes of aerosol that include particles critical to cloud formation and infection transmission.Read moreRead less

This project aims to establish complementary scanning electron microscope (SEM) facilities at The University of Melbourne and LaTrobe University to advance research into crops, disease, neurosciences and coral reefs. SEMs are rapidly evolving instruments that permit high resolution imaging of visible size samples such as parts of plants and animals. The potential innovations, applications and benefits to society are far reaching, with the facility expected to impact the development of drought and salinity tolerance in crops, production of fibres by plants, resilience of Great Barrier Reef corals to warming, advances in medicinal agriculture, control of important diseases of livestock and humans, and sensory processing and ocular disease.Read moreRead less
Understanding the life and death of Mucosal-associated invariant T cells. Cell death of naïve T cells in lymphoid organs is well-understood. However, T cells only gain their function upon activation, and how activated T cells regulate their life or death remains unclear. Mucosal-associated Invariant T (MAIT) cells are abundant in non-lymphoid tissues as key local players in immunity, and share some features of activated conventional T cells. This project aims to define how MAIT cell survival and ....Understanding the life and death of Mucosal-associated invariant T cells. Cell death of naïve T cells in lymphoid organs is well-understood. However, T cells only gain their function upon activation, and how activated T cells regulate their life or death remains unclear. Mucosal-associated Invariant T (MAIT) cells are abundant in non-lymphoid tissues as key local players in immunity, and share some features of activated conventional T cells. This project aims to define how MAIT cell survival and death are controlled. It combines methods we developed to track MAIT cells in vivo with expertise in cell death analysis. This project is expected to elucidate the complex mechanisms controlling MAIT cell survival/death and increase our fundamental understanding of cell death mechanisms of activated T cells.Read moreRead less
Chemical probes to dissect the cell cycle of globally important parasites . This project aims to develop new reagents, called chemical probes, to visualise key biological events in globally important pathogens. We will use innovative chemistry to modify the building blocks of DNA and provide researchers with essential tools to 'see' DNA synthesis in order to study growth and replication of pathogens in combination with microscopy. This project expects to support a major technical advance that wi ....Chemical probes to dissect the cell cycle of globally important parasites . This project aims to develop new reagents, called chemical probes, to visualise key biological events in globally important pathogens. We will use innovative chemistry to modify the building blocks of DNA and provide researchers with essential tools to 'see' DNA synthesis in order to study growth and replication of pathogens in combination with microscopy. This project expects to support a major technical advance that will address important gaps in our understanding of many pathogens (e.g. those that cause malaria and tuberculosis), at both the cellular and molecular levels. This should provide significant benefits by enabling researchers worldwide to identify new intervention opportunities that target unique aspects of pathogen biology.Read moreRead less

Understanding how bacteria adapt and function in the complex gut ecosystem. This project aims to investigate the role of the gut ecosystem in defining the structure and function of microbes. Given that one of the current challenges in microbiology is our inability to study individual microbes directly from complex, multi-microbial niches, this project aims to develop multidisciplinary methods to study microbes in their native state, to understand how they adapt to live in the gut. This understan ....Understanding how bacteria adapt and function in the complex gut ecosystem. This project aims to investigate the role of the gut ecosystem in defining the structure and function of microbes. Given that one of the current challenges in microbiology is our inability to study individual microbes directly from complex, multi-microbial niches, this project aims to develop multidisciplinary methods to study microbes in their native state, to understand how they adapt to live in the gut. This understanding should provide fundamental insights into adaptation mechanisms that lead to bacterial proliferation, disease and antibiotic resistance. As well as enhancing interdisciplinary collaborations, this work should provide economic benefits by contributing to improved gut health of animals, and more efficient food production.Read moreRead less

All life depends on a cell envelope to enclose the chemical reactions that make life possible. But how do cell envelopes grow? How each component of the cell envelope is incorporated into the envelope at the right amount and in the right time to prevent cell death, has been a longstanding question in bacteriology. Using a unique combination of high through put genetic screens and biochemical approaches, this project will characterise a key regulator of cell envelope growth in Gram-negative bacteria. Knowledge arising from this research will provide insight into a fundamental process in bacteria, will develop new technology to probe protein interactions, and will provide novel avenues to solve infection in plants, humans and animals.Read moreRead less
Signalling pathways for sexual differentiation of apicomplexan parasites. This project aims to study the sexual development of apicomplexan parasites, which cause major diseases in humans, livestock and wildlife, including malaria. Only sexually differentiated cells can survive in the mosquito vector and hence this development is essential for the parasite's life-cycle.

Only sexually differentiated cells can survive in the mosquito vector and hence this development is essential for the parasite's life-cycle. This project will employ a new approach that separates female from male parasites, thus enabling new information to be gleaned about the development of these parasites. The expected outcomes are an understanding of the mechanisms of sexual differentiation and a functional characterisation of novel sex-specific molecules. This will provide significant benefits, such as pivotal prerequisites for new approaches to parasite intervention.Read moreRead less

Combining vibrational spectroscopic approaches and metabolomic techniques, the project will investigate cell populations, single cells and subcellular structures in search of biomarkers for drug resistance. The discovery of such biomarkers could lead to improved disease management and eradication programs through identification and treatment of drug resistant pathogens in individuals that have the potential to re-infect the community.Read moreRead less
