Summary
Exploring new territory in climatic adaptation research: integrating molecular genetics with species' thermal tolerance limits. Predicting species' responses to environmental change requires mechanistic links between whole-organism physiological stress responses and underlying cellular mechanics. This project integrates cutting-edge methods in molecular and evolutionary genetics to probe species' responses to environmental change in the context of a warming environment.

Summary
Impact of shift work on emergency performance, decision making and stress. Sleep and circadian disruptions due to shift work are common for emergency personnel, but their impact on team performance and decision making is poorly understood. Using an ecologically relevant simulated work environment, this project aims to examine how shift work influences work performance and team decision making and identify potential stress-related mechanisms that may underpin impairments in these outcomes.

Sleep and circadian disruptions due to shift work are common for emergency personnel, but their impact on team performance and decision making is poorly understood. Using an ecologically relevant simulated work environment, this project aims to examine how shift work influences work performance and team decision making and identify potential stress-related mechanisms that may underpin impairments in these outcomes. By understanding the role poor sleep and circadian misalignment due to shift work play on work performance, this project will inform industry practices and training approaches designed to optimise workplace safety and emergency performance. This project will benefit emergency personnel and the people who depend on these services.Read moreRead less

This project aims to use single-cell gene regulation networks to predict cell types. Computational approaches are needed to recapitulate how the over 37 trillion cells program the shared genome sequence in a human body to create astoundingly diverse forms and functions. This project integrates millions of high-resolution single-cell gene expression profiles with large-scale population regulatory data to systematically reconstruct gene regulatory networks. These networks are the molecular basis for understanding human cells. This projects outcomes intend to include the first reference single-cell regulatory database and novel methods and software to predict individual cells. This project will contribute to advancing Australia's capabilities in single-cell, precision medicine, and big biological data analysis leading to significant scientific, societal and commercial benefits.Read moreRead less

Summary
The forest and the trees: How global brain rhythms facilitate local information processing. One of the greatest challenges in understanding the brain is the enormous range of scales it operates on, from single neurons a few microns across to entire hemispheres on the scale of tens of centimetres. This project will investigate how large-scale brain rhythms influence and facilitate information processing, particularly motor control, among small networks of individual neurons. The research question ....The forest and the trees: How global brain rhythms facilitate local information processing. One of the greatest challenges in understanding the brain is the enormous range of scales it operates on, from single neurons a few microns across to entire hemispheres on the scale of tens of centimetres. This project will investigate how large-scale brain rhythms influence and facilitate information processing, particularly motor control, among small networks of individual neurons. The research questions will be addressed by combining detailed computer simulations with data-driven analyses of empirical human and monkey brain dynamics. The outcomes of this project will provide a richer understanding of how our brains encode and process information, leading to practical benefits such as improved control of artificial limbs.Read moreRead less

The immune system surveys our body examining molecules that signal whether or not everything is ok. T cells are a central to this and use their receptors to monitor these molecular signals. A specialised subset of T cells known as gamma-delta T cells are critical to detecting infection and cancer, yet their fundamental biology is poorly understood. This project aims to unravel this elusive biology. The aims are to understand 1. The diversity in function between gamma-delta T cell subsets, and 2. The diversity in gamma-delta T cell receptors and the molecules that these receptors detect. This work is essential for understanding gamma-delta T cell immunology which is critical if we ultimately wish to harness this to improve human health.Read moreRead less

Regulation of organ size and stem cell hierarchy in the developing kidney. Transient stem/progenitor cell populations play essential roles in establishing organ systems. The balance between self-renewal and differentiation in the nephron progenitor population plays a major, but poorly understood, role in regulating kidney development.

The balance between self-renewal and differentiation in the nephron progenitor population plays a major, but poorly understood, role in regulating kidney development. Factors produced by undifferentiated progenitors promote organ expansion, whereas differentiation of these cells builds functional capacity. What is not clear is how the balance between self-renewal and differentiation is regulated in these cells, nor how the control of this fate decision impacts on optimal organ development. This project aims to dissect the molecular identity, regulation, and influence of this stem cell population on kidney development.Read moreRead less

Using a longitudinal public-health database, the Raine Study, and a theoretical framework from the field of Nutritional Ecology, the project will provide new knowledge on how nutrition affects key life-history traits in humans including immune function, reproductive health, physical appearance, and healthy ageing. A systematic literature review on how diet impacts these life-history traits in animals generally, and an experimental study of the effect of diet on health and reproduction in the house mouse (a lab analog species for humans) will complement the Raine Study findings.Read moreRead less

This project aims to improve our understanding of the complex regulatory mechanisms that increase genetic and phenotypic robustness. Survival of organisms depends on their ability to cope with genetic variation. A novel process of genetic compensation has recently been identified, producing a normal phenotype in a homozygous mutant, that would be expected to have deleterious effects. This project will reveal how compensation is achieved by examining the molecular pathways that are activated following genetic mutation. This project is expected to strengthen Australian reputation in evolutionary genetics, and in turn enhance our understanding of how organisms adapt to changing environments.Read moreRead less

Summary
Estrogen-mediated regulation of gene expression via transcriptional and translational control: complementary, synergistic or opposing responses? Hormones dictate cellular behaviour by activating pre-programmed responses. The sex hormone estrogen affects cell fate by regulating the gene expression, but it is unknown to which extent this response occurs via activation of genes or control of already transcribed gene. The project will investigate how the cell integrates the complex estrogen signals.
