Long range interactions of atoms. Atomic physics is often described as both a basic and enabling discipline and the present project on long range atomic interactions fits within both of those categories. The results of the project will lead to a more thorough understanding of the details of long range atom-atom interactions. This will lead to Australian expertise making a significant contribution in a number of cutting edge areas in atomic and molecular physics.
Application of variational methods in atomic and molecular physics. Atmoic physics is both a basic an enabling science and this project will improve fundamental knowledge about the interactions of electrons and positrons with atoms and molecules. Research will be directly relevant to the activities of the National Positron Beam-Line (located at the Australian National University) which is directed to break-through research in matter-antimatter interactions and materials characterisation.

Managing acid mine drainage in northern Australia using microbial mats. One of the most difficult environmental issues for the mining industry is acid mine drainage (AMD) that can lead to significant environmental damage. This project aims to identify microbes and characterise their roles in AMD formation in north Australia. We will use our new knowledge to design and trial microbial mats for the treatment of AMD. A successful AMD microbial treatment technology will minimise the risk of acid run ....Managing acid mine drainage in northern Australia using microbial mats. One of the most difficult environmental issues for the mining industry is acid mine drainage (AMD) that can lead to significant environmental damage. This project aims to identify microbes and characterise their roles in AMD formation in north Australia. We will use our new knowledge to design and trial microbial mats for the treatment of AMD. A successful AMD microbial treatment technology will minimise the risk of acid runoff and metal seepage into rivers and through groundwater. AMD treatment technology we develop in the tropics where we experience the extremes of dry and wet seasons will require only minor modification to operate in temperate climates however the reverse is not true.

Coastal monitoring using metal resistant microbes. We will develop an early warning, rapid biological assessment (RBA) for sediment toxicity that can be used alongside chemical tests to detect sub-chronic changes in the environment. The assessment will be validated by extensive testing of impacted sediment. We will show how the RBA fits into existing decision trees defined by the Australian and New Zealand Environment and Conservation Council (ANZECC) 2000 Guidelines. The biological tests result ....Coastal monitoring using metal resistant microbes. We will develop an early warning, rapid biological assessment (RBA) for sediment toxicity that can be used alongside chemical tests to detect sub-chronic changes in the environment. The assessment will be validated by extensive testing of impacted sediment. We will show how the RBA fits into existing decision trees defined by the Australian and New Zealand Environment and Conservation Council (ANZECC) 2000 Guidelines. The biological tests resulting from this project will be as rapid and straightforward as existing chemical tests, which will facilitate industry acceptance. The project has strong industry involvement from mining companies, the Environment Protection Agency (EPA) and traditional owners. These partners will guide this project and facilitate communication to the wider industry to aid acceptance and uptake.Read moreRead less
Defining the links between climate change, marine disease and food security. This project will deliver critical new knowledge on the causes of marine pathogen outbreaks that threaten Australia’s $1.6 billion aquaculture industry. Several members of the same genus of bacteria have been implicated in recent mass mortality events in aquaculture species, as well as human illness in consumers of seafood, yet the triggers for unprecedented outbreaks of these pathogens are unknown. By coupling a suite ....Defining the links between climate change, marine disease and food security. This project will deliver critical new knowledge on the causes of marine pathogen outbreaks that threaten Australia’s $1.6 billion aquaculture industry. Several members of the same genus of bacteria have been implicated in recent mass mortality events in aquaculture species, as well as human illness in consumers of seafood, yet the triggers for unprecedented outbreaks of these pathogens are unknown. By coupling a suite of sophisticated molecular biological tools and physiological measurements, this research will resolve the role of environmental disturbances including marine heat waves, floods and plastic pollution in stimulating marine pathogen outbreaks, thereby informing efforts to safeguard Australia’s food security and food safety.Read moreRead less
Can Skin Infection With Group A Streptococcus Cause Acute Rheumatic Fever?

Summary
It is traditionally taught that the cause of acute rheumatic fever (ARF) is always infection of the throat with the bacterium group A streptococcus (GAS). However, in Aboriginal communities of the Top End of the Northern Territory the incidence of ARF is the highest reported in the world, yet GAS is uncommonly isolated from the throat. There is further information to suggest that GAS skin sores may underlie many cases of ARF. If this were proven, it would completely alter the traditional view of ....It is traditionally taught that the cause of acute rheumatic fever (ARF) is always infection of the throat with the bacterium group A streptococcus (GAS). However, in Aboriginal communities of the Top End of the Northern Territory the incidence of ARF is the highest reported in the world, yet GAS is uncommonly isolated from the throat. There is further information to suggest that GAS skin sores may underlie many cases of ARF. If this were proven, it would completely alter the traditional view of the cause of ARF, and have important implications for prevention of ARF around the world. Presently, these approaches focus on diagnosing and treating sore throat, but no country has proven that such a program can be successful in substantially reducing new cases of ARF. If it was known that skin infection could lead to ARF, then countries (including Australia) could emphasise the importance of skin health programs. A further benefit of this knowledge would be to influence GAS vaccine development, which presently is largely focused on the prevention of sore throat. A different possibility has recently been raised - that the cause of ARF may not always be GAS, but instead that the related bacteria GCS and GGS may have the potential to cause this disease. Proof of this hypothesis would even more dramatically alter our understanding of disease causation, prevention, and vaccine development. We propose to determine the cause of ARF in Aboriginal communities by regularly swabbing families of people with a history of ARF, and using genetic fingerprinting of the bacteria from the skin and throat swabs. When cases of ARF occur, we will be able to determine the site and type of infection that precipitated the attack. We will conduct a related study in more communities, in which we will swab family members of people with ARF and of control families (without ARF) to determine the bacteria most commonly isolated from ARF families.Read moreRead less
