Effects of river plumes on nearshore ecosystems: organic matter flows and food web consequences. River plumes may subsidize nearshore food webs by exporting land-derived material and by stimulating marine phytoplankton production via nutrient delivery. Whereas previous documentation of the biological responses to plumes has been mostly limited to large rivers and to primary production, this project targets small systems that discharge directly onto open coasts, and focuses on the fate of plume ....Effects of river plumes on nearshore ecosystems: organic matter flows and food web consequences. River plumes may subsidize nearshore food webs by exporting land-derived material and by stimulating marine phytoplankton production via nutrient delivery. Whereas previous documentation of the biological responses to plumes has been mostly limited to large rivers and to primary production, this project targets small systems that discharge directly onto open coasts, and focuses on the fate of plume material. Work on carbon pathways will centre on pelagic and benthic food chains associated with plumes, and will also test whether nearshore waters and sandy beaches are coupled via onshore advection of plume material.Read moreRead less
Covalent Hydrogen Bond Mimetics of Helical Peptide Hormones. Peptide hormones have been identified that adopt a helical shape when bound to their receptor. The project will produce new versions of these hormones by the use of directly bonded chemical linkers in place of the relatively weak helix hydrogen bonds. The resulting hormone mimics will be more stable, have lower molecular weight and be more selective than the natural hormones making them more suitable as drugs. Our new chemical techn ....Covalent Hydrogen Bond Mimetics of Helical Peptide Hormones. Peptide hormones have been identified that adopt a helical shape when bound to their receptor. The project will produce new versions of these hormones by the use of directly bonded chemical linkers in place of the relatively weak helix hydrogen bonds. The resulting hormone mimics will be more stable, have lower molecular weight and be more selective than the natural hormones making them more suitable as drugs. Our new chemical techniques allow us for the first time to fully investigate this approach which if successful will be applicable to many other helical peptides and therefore could be an important drug development technique.Read moreRead less

The venoms of Australian tarantula spiders provide a unique and untapped source of bioactive molecules. From a large stock of venom, and in collaboration with Australian pharmaceutical company Xenome, we will develop a comprehensive library of venom components suitable for drug screening. Potential national benefits from this work include a huge reduction in the healthcare bill deriving from a new treatment for pain, as well as substantial royalty returns from drugs sales. Discoveries from the program are also likely to lead to an enhancement in Australia's reputation in the neurosciences and to the development of new diagnostic research tools. The major community benefit will be a reduction in the suffering of chronic pain patients.Read moreRead less
Understanding biological pathways underlying social behaviour in humans. This project aims to show for the first time how oxytocin interacts with neural social and reward pathways to guide social behaviour. Oxytocin is a natural neuropeptide and hormone that has a critical role in the regulation of social behaviour across mammalian species.

This project aims to show for the first time how oxytocin interacts with neural social and reward pathways to guide social behaviour. Oxytocin is a natural neuropeptide and hormone that has a critical role in the regulation of social behaviour across mammalian species. In animals, direct evidence demonstrates how endogenous and exogenous oxytocin interacts with social and reward neural pathways to alter social behaviour, including social recognition, relationship formation, and long-term bonds. The project intends to use radio-labelling techniques in combination with positron emission tomography to track oxytocin and show what regions of the brain oxytocin impacts to then influence social cognition and behaviour in humans.Read moreRead less
Gene Expression Profiling and de novo Transcriptome Sequencing using Geneballs. The purpose of the project is to demonstrate that bead-based technology can be used in applications that currently require DNA hybridisation in order to overcome existing deficiencies in microarray technology.

The purpose of the project is to demonstrate that bead-based technology can be used in applications that currently require DNA hybridisation in order to overcome existing deficiencies in microarray technology. By providing the capability to quickly and efficiently produce, screen and utilize biomolecule libraries of nearly unlimited size, this technology provides the key to unlock the power of genomics and proteomics for use in real world applications. The project has two aspects. First, relatively small directed cDNA-bead libraries will be compared to known low-density cDNA microarrays to validate the technique for utility in gene expression profiling. Secondly, large libraries containing short oligonucleotide sequences will be used for de novo sequencing of a complete transcriptome. Proof-of-concept in either case will pave the way for many genomic applications and catapult the technology to 'blockbuster' status.Read moreRead less

Venomous arthropods produce a myriad of biologically active peptides, with many having potential as pharmacological tools, bioinsecticides and pharmaceuticals. Most studies to date have focussed on large arthropods; smaller species remain neglected due to the difficulties of venom collection. This project seeks to further advance the pioneering imaging mass spectrometry approaches the project team developed for imaging toxins in the venom glands of spiders and centipedes. By combining high-resolution matrix-assisted laser desorption ionisation imaging data with histological and transcriptomic information the project aims to provide the first detailed insights into the neglected world of miniature arthropod venoms. The approaches developed by this project aim to have wide application in the field of biology.Read moreRead less

This project will add to our knowledge of Australian dinosaurs and the world they inhabited. Dinosaurs are often the means through which many people, especially children, are introduced to science. This project has the potential to greatly enhance this attraction to science, using the results of research on Australian dinosaurs. It has direct links with a number of national and international museum exhibitions, and in western Queensland the results will be incorporated into a newly developed regional interpretive centre in Isisford. The enormous social and economic benefits linked to this initiative will open up numerous opportunities for local businesses, and increase the appreciation for science and exploration in outback areas.Read moreRead less
