Rapid motor responses in young and older adults. This proposal aims to contribute to our understanding of basic neural mechanisms mediating rapid motor actions across our lifespan. One in four Australians will be over the age of 65 by the year 2056. The project plans to investigate how changes in brain structure and function, as well as alterations in cognitive processing abilities that occur in older age, affect rapid choices between various alternative motor actions as well as our ability to s ....Rapid motor responses in young and older adults. This proposal aims to contribute to our understanding of basic neural mechanisms mediating rapid motor actions across our lifespan. One in four Australians will be over the age of 65 by the year 2056. The project plans to investigate how changes in brain structure and function, as well as alterations in cognitive processing abilities that occur in older age, affect rapid choices between various alternative motor actions as well as our ability to stop motor responses once they are planned. It plans to combine noninvasive brain stimulation with novel behavioural experiments and computational modelling techniques to develop fundamental new knowledge of the natural processes that characterise age-related changes in rapid motor actions.Read moreRead less
The Antarctic Slope Current in a warming climate. Melting Antarctic ice sheets are responsible for 28% of global sea level rise in recent decades, and can contribute more than 1 metre of sea level rise by year 2100, and a staggering 15 metres by 2500. Increased glacial melt rates are best understood by studying changes in the circulation of water around the Antarctic coastline. The combination of physical processes that must be resolved in this region places a high demand on ocean observations a ....The Antarctic Slope Current in a warming climate. Melting Antarctic ice sheets are responsible for 28% of global sea level rise in recent decades, and can contribute more than 1 metre of sea level rise by year 2100, and a staggering 15 metres by 2500. Increased glacial melt rates are best understood by studying changes in the circulation of water around the Antarctic coastline. The combination of physical processes that must be resolved in this region places a high demand on ocean observations and modelling systems. This project uses a series of high-resolution ocean and ice experiments, cross-validated with observations, to provide a deeper understanding of how waters at the Antarctic margin respond to both anthropogenic and natural climate forcing.Read moreRead less
Distribution of ocean heat uptake and its implications for sea level and climate change. Increasing sea levels and ocean temperatures provide critical evidence of long term warming of the climate system. This project will investigate geographical changes in the vertical distribution of heat uptake by the ocean and contribution to sea level changes, including understanding of physical mechanisms and the role of human activity and other natural external and internal factors. The expected outcomes ....Distribution of ocean heat uptake and its implications for sea level and climate change. Increasing sea levels and ocean temperatures provide critical evidence of long term warming of the climate system. This project will investigate geographical changes in the vertical distribution of heat uptake by the ocean and contribution to sea level changes, including understanding of physical mechanisms and the role of human activity and other natural external and internal factors. The expected outcomes will contribute to place more rigorous constraints on the likelihood of future warming and sea level rise projections, and are aligned with scientific deliverables required to address key questions in support of Australia’s climate change policy.Read moreRead less
Tools for manipulating neuronal activity for behavioural studies. This project aims to develop optogenetic tools neuroscientists can use to better understand brain circuitry and the functional effects of specific neurons on behaviour. Linking the activity of individual neurons in the brain to specific behaviours is a major challenge in neuroscience. Optogenetics achieve this by using light to control the activity of neurons. This has advanced understanding of behaviour and neurocircuitry. This p ....Tools for manipulating neuronal activity for behavioural studies. This project aims to develop optogenetic tools neuroscientists can use to better understand brain circuitry and the functional effects of specific neurons on behaviour. Linking the activity of individual neurons in the brain to specific behaviours is a major challenge in neuroscience. Optogenetics achieve this by using light to control the activity of neurons. This has advanced understanding of behaviour and neurocircuitry. This project is expected to increase understanding of brain function at the cellular and system levels, and advance Australia’s multidisciplinary research capacity in neuroscience, cognitive sciences and nanobiotechnology to ultimately treat neurological disorders.Read moreRead less
Autonomous platforms and biotagging data: new approaches for understanding variability and change across the Antarctic ocean/sea-ice climate system. This project aims to advance our ability to assess and monitor climate change across the Antarctic ocean/sea-ice system. Ocean/sea-ice interactions have a critical role in the global climate and there is an urgent need to determine how these are responding to climate change. This project will overcome gaps in existing observational datasets that cur ....Autonomous platforms and biotagging data: new approaches for understanding variability and change across the Antarctic ocean/sea-ice climate system. This project aims to advance our ability to assess and monitor climate change across the Antarctic ocean/sea-ice system. Ocean/sea-ice interactions have a critical role in the global climate and there is an urgent need to determine how these are responding to climate change. This project will overcome gaps in existing observational datasets that currently limit our understanding of spatiotemporal variability and change in ocean around Antarctica. This study will use two new approaches, biotagging and autonomous platforms, to greatly improve our capacity to model and predict the impacts of climate change on the Antarctic ocean/sea ice system and beyond.Read moreRead less
