The proposed project is based on the recent progress the applicants have made by (i) identifying a novel family of mechanosensitive (MS) channels in cell-walled organisms, which include Archaea and Bacteria (prokaryotes), as well as fungi and plants (eukaryotes), and (ii) determining basic aspects of the structural dynamics of MscL, the prototype MS channel, using electronparamagnetic resonance spectroscopy and molecular dynamics simulations in combination with the patch clamp technique. The aim of the project is to elucidate the molecular principles underlying the function of MS channels, which is of fundamental importance for understanding of the biophysics and physiology of mechanosensory transduction throughout the biological world.Read moreRead less

Computational Molecular Science (CMS) involves the use of theory and computational methods to simulate and visualise molecular systems ranging from small atmospheric species to proteins, nucleic acids, chemical polymers and materials. It represents our most incisive expression of what we understand about the molecular basis of nature. The CMS network will integrate and cross-fertilize both fundamental and application-based expertize in molecular scale computations in the fields of nanoscience, biomaterials, biotechnology, biomedical science and environmental science. It will uncover and explore critical new interdisciplinary science and create new molecular-based paradigms that will drive advances in these fields over the next decade.Read moreRead less
Expectations and commitments in the Australia-USA alliance. This project aims to investigate the gap between the high expectations of mutual support and the lack of detailed security commitments in the Australia-US Alliance. The project intends to use a focused approach that captures thematic aspects of the alliance through project frames and historical slices across time.

This project aims to investigate the gap between the high expectations of mutual support and the lack of detailed security commitments in the Australia-US Alliance. The project intends to use a focused approach that captures thematic aspects of the alliance through project frames and historical slices across time. Expected outcomes can advance understanding of how alliances operate as security institutions. The outcomes can help to promote a more informed national conversation about the costs and benefits of Australia's security relationship with the United States of America (USA) and contribute to debates over the future of the Australia-USA Alliance during a period of strategic uncertainty.Read moreRead less

Summary
Formation of the osteocyte network in bone matrix. The formation of new bone, which occurs throughout life for bone renewal and acutely after fractures, entraps a network of cells that can detect micro-damage and direct repair mechanisms. Mathematical and computational methods will be used to understand how this network can lead to a self-detecting and self-repairing biomaterial.
The role of mechanosensitive (MS) ion channels in magnetoreception. The magnetic field of the Earth has for long been known to influence the behaviour and orientation of a variety of organisms. Experimental study of the magnetic sense has however, been impaired by the lack of a plausible cellular and/or molecular mechanism providing meaningful explanation for detection of magnetic fields by living organisms. Recently, mechanosensitive (MS) ion channels have been implied to play a role in magneto ....The role of mechanosensitive (MS) ion channels in magnetoreception. The magnetic field of the Earth has for long been known to influence the behaviour and orientation of a variety of organisms. Experimental study of the magnetic sense has however, been impaired by the lack of a plausible cellular and/or molecular mechanism providing meaningful explanation for detection of magnetic fields by living organisms. Recently, mechanosensitive (MS) ion channels have been implied to play a role in magnetoreception. Based on our preliminary investigations, which suggest that the activity of bacterial MS channels may be affected by magnetic fields, we propose to study effects of magnetic fields on MS ion channels in Gram-negative bacteria Escherichia coli and Magnetospirillum magnetotacticum. The project promises also to contribute towards better understanding of adverse effects of electromagnetic radiation on human health and towards understanding the mechanisms behind remote magnetic-nanoparticle mediated activation of MS ion channels.Read moreRead less
Examining scientific, philosophical, and folk perspectives on time=. This project aims to consider three very different physical theories, each of which reconciles quantum mechanics and general and special relativity in a different way. While science is more accessible than ever, we are increasingly faced with a scientific world-view that is antithetical to the way we see the world and experience ourselves in it. This project will consider the tension between the scientific picture of the world ....Examining scientific, philosophical, and folk perspectives on time=. This project aims to consider three very different physical theories, each of which reconciles quantum mechanics and general and special relativity in a different way. While science is more accessible than ever, we are increasingly faced with a scientific world-view that is antithetical to the way we see the world and experience ourselves in it. This project will consider the tension between the scientific picture of the world and our experience of the world, and aims to reconcile the two by bridging the gap between lived experience and scientific findings. The project will provide a range of ways of bridging the tension between these physical theories with our lived experience.Read moreRead less

Summary
Timelessness in physics and philosophy. This project aims to offer a new approach to conceptualising the nature of time focussing on the gap between our everyday understanding of time, and the picture of time inherited from current physics. It is expected that the project will result in the generation of new knowledge that supports science communication, and strengthening research ties between the arts and science.
