The cellular basis of sex-specific responses to virus infection. This project aims to explore how the sex of cells impacts virus infections in culture. To date, the sex of cells in culture has been overlooked as an important source of biological variability, but may be found to affect basic science through to anti-viral drug discovery. Using a model in which a virus can be adapted to grow better in cells of a single sex, this project expects to generate new knowledge about how sex differences im ....The cellular basis of sex-specific responses to virus infection.

To date, the sex of cells in culture has been overlooked as an important source of biological variability, but may be found to affect basic science through to anti-viral drug discovery. Using a model in which a virus can be adapted to grow better in cells of a single sex, this project expects to generate new knowledge about how sex differences impact virus-host interactions. This project expects to provide new insights into sex-based differences in how cells detect and respond to virus infection, and the extent to which the sex of cells impacts viruses in general.Read moreRead less
Targeting the host lipid environment to disrupt malaria transmission. This project aims to characterise host molecules (in particular lipids) that are crucial for the transition of malaria parasites from one host to another.

This project aims to characterise host molecules (in particular lipids) that are crucial for the transition of malaria parasites from one host to another. Malaria parasites encounter different environments upon their transition from human to the mosquito host. This project expects to generate new knowledge on physiological changes that are triggered by particular differences in micronutrient abundance that allow the parasites to survive in the new host. Anticipated outcomes include the identification of new intervention strategies and improved transmission model systems for vector-borne diseases. This gained knowledge could provide benefits to future biomedical applications by informing diagnostics or treatment of lipid associated diseases.Read moreRead less
Creation of a super-resolution map of the bacterial cytokinesis machinery . Cell division is a fundamental process essential for life.

Peril and promise: Origins and spread of integron gene cassettes. Integrons have a major role in spreading antibiotic resistance genes among pathogens. They do so by capturing gene cassettes encoding resistance, yet how these cassettes are generated, the taxa in which they originate, and the range of traits that cassettes can encode have been outstanding questions for 30 years. This project addresses these long standing questions. The project will analyze single bacterial cells to detect newly ....Peril and promise: Origins and spread of integron gene cassettes. Integrons have a major role in spreading antibiotic resistance genes among pathogens. They do so by capturing gene cassettes encoding resistance, yet how these cassettes are generated, the taxa in which they originate, and the range of traits that cassettes can encode have been outstanding questions for 30 years. This project addresses these long standing questions. The project will analyze single bacterial cells to detect newly generated cassettes and assign them to specific taxa, using an innovative method that links cassette DNA to bacterial 16S rDNA. Understanding cassette origins is the key to controlling their activity, both to harness integrons for biotechnology, and to prevent pathogens from acquiring new, dangerous traits. Read moreRead less
Messing with their minds: using deception to improve pest management. This project aims to develop new approaches to improve wildlife management by showing how deceit and misinformation can alter decision-making in pest animals. Using wild house mice as a model, it will test new theory on how animals decide whether or not to interact with wildlife control devices, like traps and baits, which is critical to all pest control efforts. The expected outcomes include new pest control tools that make s ....Messing with their minds: using deception to improve pest management. This project aims to develop new approaches to improve wildlife management by showing how deceit and misinformation can alter decision-making in pest animals. Using wild house mice as a model, it will test new theory on how animals decide whether or not to interact with wildlife control devices, like traps and baits, which is critical to all pest control efforts. The expected outcomes include new pest control tools that make strategic use of misinformation to alter decision making, to reduce a pest's ability to damage important agricultural crops such as wheat, boost the attraction of lures to traps, and improve bait uptake. These outcomes should provide significant new options for vertebrate pest control in Australia and globally.Read moreRead less

Digitally-Integrated Smart Sensing of Diverse Airborne Grass Pollen Sources. Grass pollen is the main outdoor allergen source globally, triggering hayfever and asthma in up to 500 million people. With over 10,000 species, the influence of grass type, location and climate on pollen in the air is not yet known. This is a key issue since subtropical and temperate grasses differ in response to environmental factors. The project aims to use artificial intelligence on digital camera images to learn to ....Digitally-Integrated Smart Sensing of Diverse Airborne Grass Pollen Sources. Grass pollen is the main outdoor allergen source globally, triggering hayfever and asthma in up to 500 million people. With over 10,000 species, the influence of grass type, location and climate on pollen in the air is not yet known. This is a key issue since subtropical and temperate grasses differ in response to environmental factors. The project aims to use artificial intelligence on digital camera images to learn to see local grass flowers and integrate this with air sensors trained to detect grass pollen types. The expected outcomes are new capacities to track airborne grass pollen types. These outcomes can transform how pollen can be monitored to reduce the burden of allergies, and provide evidence of changing airborne pollen loads.

This project aims to address the legal and policy dimensions of hepatitis C discrimination. Hepatitis C is a major public health challenge linked to profound discrimination, including in law and policy. Treatments introduced in 2016 improved cure rates; optimism about disease elimination is high, but questions remain about discrimination faced by those who are cured. This interdisciplinary project’s goal is to generate new knowledge about hepatitis C discrimination in a post-cure context, and identify opportunities for legal and policy reform.

Extracellular vesicles (EVs) are small membrane bound sacs that carry information between cells in essentially all organisms. EVs are also produced by bacterial and fungal pathogens and have a crucial role in infection in mammals . We propose that fungal EVs are key players in the establishment of fungal diseases in plants. We have isolated EVs from the cereal pathogen Fusarium graminearum which decreases yield and quality of grain in major food crops such as wheat, barley and corn. This project will focus on the cargo that EVs transport through the fungal cell wall and into the plant host and will establish the role of this cargo in disease progression. Ultimately, this knowledge will be used to design new strategies for disease control.Read moreRead less

ABC toxins are the main virulence factors in many species of naturally-occurring bacterial pathogens of insect pests. This project aims to establish that ABC toxins represent a new protein machinery that may be used more widely throughout cells and other organisms to direct the intercellular delivery of bioactive proteins in a highly cell-specific manner. The project expects these findings to enable the development of biopesticides based on ABC toxins, and generic intercellular protein delivery devices for biotechnological use.Read moreRead less
