Energetically Open Systems Research Network Study. Conceptual frameworks arising in the physical sciences, such as non-equilibrium statistical mechanics and thermodynamics, synergetics, chaos and dynamical systems theory, are seminal in the emerging science of complexity. This study will lay the groundwork for a network to link Australian and overseas research on these fundamental concepts, and their application within the context of entropy-producing systems vital to the long-term sustainabilit ....Energetically Open Systems Research Network Study. Conceptual frameworks arising in the physical sciences, such as non-equilibrium statistical mechanics and thermodynamics, synergetics, chaos and dynamical systems theory, are seminal in the emerging science of complexity. This study will lay the groundwork for a network to link Australian and overseas research on these fundamental concepts, and their application within the context of entropy-producing systems vital to the long-term sustainability of the earth - oceans, atmosphere, biosphere, CO2-free energy production, space and solar environment. The network would facilitate the development of young investigators and be linked into wider complex systems networks such as the CSIRO Centre for Complex Systems Science.Read moreRead less
From structures to systems: A hierachical approach to understanding sub-cellular components. This program will dramatically extend the range of biomolecular systems that can be modelled with near atomistic precision. It will provide a better understanding of the structure and function of proteins involved in the regulation of membrane fusion and fission as well as shedding light on the assembly of large-scale protein-protein and protein-membrane complexes in general.

Advanced optical tweezers technologies for biophysical measurements. While much is understood about the fundamental unit of life, the living cell, such as their behaviour and their biochemistry and genetics, the interface between these two is only poorly known. We will use optical tweezers, which can trap and move microscopic objects without physical contact, to measure forces on the molecular and cellular scale to study the mechanical properties of cells and biomolecules, including molecular mo ....Advanced optical tweezers technologies for biophysical measurements.

We will use optical tweezers, which can trap and move microscopic objects without physical contact, to measure forces on the molecular and cellular scale to study the mechanical properties of cells and biomolecules, including molecular motors, which are Nature's own nanomachines, advanced our knowledge of the fundamental machinery of life.Read moreRead less
Signalling cross-talk through Suppressors Of Cytokine Signalling (SOCS) initiates luteolysis in the ovary. Members of the newly discovered SOCS protein family block cytokine signal transduction pathways, including those for prolactin and GH. We have discovered that one of these proteins, SOCS-3, is upregulated in the corpus luteum of the ovary by prostaglandins and propose that induction of prolactin or GH resistance is a hitherto unrecognised and critical step in luteolysis. We have also disco ....Signalling cross-talk through Suppressors Of Cytokine Signalling (SOCS) initiates luteolysis in the ovary.

We have discovered that one of these proteins, SOCS-3, is upregulated in the corpus luteum of the ovary by prostaglandins and propose that induction of prolactin or GH resistance is a hitherto unrecognised and critical step in luteolysis. We have also discovered that this cross-talk between prostaglandin- and cytokine-receptor signalling pathways occurs in preadipocyte and breast cell lines and propose that this research will serve as a paradigm for understanding how sensitivity to cytokines can be controlled at a molecular level.Read moreRead less

Summary
Automated Patch Clamp System. Ion channels are membrane proteins that underlie cell function and are therefore important drug targets. The patch clamp technique is the most powerful tool available to study the function of single ion channels. The recent automation of this technology represents a quantum leap in our ability to perform high throughput screening of novel natural and synthetic compounds as drug leads. This will lead to an urgently needed increase in capacity, increasing the volume o ....Automated Patch Clamp System.

The patch clamp technique is the most powerful tool available to study the function of single ion channels. The recent automation of this technology represents a quantum leap in our ability to perform high throughput screening of novel natural and synthetic compounds as drug leads. This will lead to an urgently needed increase in capacity, increasing the volume of research and its outcomes, which will benefit the Australian pharmaceutical industry and biosciences research community.

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

Is Calcium part of the mechanism used in glucose signalling in embryogenesis. A vital stage in the development of the embryo is formation of the blastocyst about 4 days after conception. For this to happen the embryo must receive glucose from the mother. We believe that rather being used by the embryo to generate energy, this glucose acts as a signal to switch on the developmental pathway leading to blastocyst formation. Without this signal there is no blastocyst and the pregnancy fails. The pr ....Is Calcium part of the mechanism used in glucose signalling in embryogenesis.

We believe that rather being used by the embryo to generate energy, this glucose acts as a signal to switch on the developmental pathway leading to blastocyst formation. Without this signal there is no blastocyst and the pregnancy fails. The project investigates this signal mechanism. The results will advance understanding of the mechanisms regulating development and in particular link the mother's nutritive status to her fertility during very early pregnancy.Read moreRead less

Endowing aircraft with the capability of autonomous flight and landing has been a major challenge in engineering technology. There is now considerable interest, nationally and world wide, in the development of small, intelligent, autonomous airborne vehicles for application in a number of areas of defense, surveillance and space exploration. The proposed research will help Australia maintain a leading edge in uncovering important biological principles of flight control that can be translated into useful technological applications.Read moreRead less
