Echo Remediation Ltd. has a new reduction cell that uses sulfur and bacteria to remove heavy metals and acidity from mine leachates, but development is now required to make it viable. The project aims to optimise the process using molecular approaches to study the effects of operating conditions on the bacterial communities. As part of the investigation, active iron reducers will be selected and introduced to the cell (in conjunction with chemical amendments) and their colonization monitored. The new technology once developed has the potential to be used at mine sites in Australia and overseas and its employment offers a sustainable, biological "green" approach to mine waste remediation.Read moreRead less

Summary
One of the major reasons for the clinical symptoms of neurological diseases such as Alzheimer’s disease and Motor Neuron Disease is the loss of connections between the nerve cells. Nerve cells are connected by specialized processes called axons. In disease these processes can breakdown. This project specifically looks at how axons break down in disease and tests therapeutic strategies to protect them.
Time-lapse geophysical monitoring of acid mine drainage at Savage River Mine, North-western Tasmania. This project will apply geophysical methods to image and monitor the subsurface distribution, and short and long-term temporal variations in ground conductivity associated with Acid Mine Drainage (AMD) at the Savage River Mine, Tasmania. AMD is a major environmental problem affecting mining operations across Australia. Geophysical techniques are inexpensive means of mapping variations in subsu ....Time-lapse geophysical monitoring of acid mine drainage at Savage River Mine, North-western Tasmania. This project will apply geophysical methods to image and monitor the subsurface distribution, and short and long-term temporal variations in ground conductivity associated with Acid Mine Drainage (AMD) at the Savage River Mine, Tasmania. AMD is a major environmental problem affecting mining operations across Australia. Geophysical techniques are inexpensive means of mapping variations in subsurface electrical conductivity related to changes in groundwater levels and contaminant concentration. The major outcomes of this project will be development of appropriate geophysical methods and interpretation techniques for delineation and monitoring of AMD at sites characterised by high seasonal rainfall and significant topography.Read moreRead less

Summary
Amyotrophic lateral sclerosis (ALS), the major cause of motor neuron disease, is a devastating diseasse for which there is no cure. There have been significant advances in understanding the pathology of ALS yet we still don’t know what causes the dying back of spinal motor neurons. We have new evidence that suggests that ALS may, in part, be caused by excitotoxcity - or over stimulation - of neurons in the spinal cord. We will follow this lead using a range of cutting edge experimental models.
Phosphate stabilisation of metalliferous mine wastes: The key to solving a major environmental issue? Mine wastes represent the greatest proportion of solid waste produced by mankind. Unconstrained drainage from sulfide-rich mine wastes impacts on water, soil and sediment quality. This project will establish the scientific principles of phosphate stabilisation, which involves the addition of phosphate compounds to mine wastes and soils to permanently contain metals and acid. A solid understandin ....Phosphate stabilisation of metalliferous mine wastes: The key to solving a major environmental issue? Mine wastes represent the greatest proportion of solid waste produced by mankind. Unconstrained drainage from sulfide-rich mine wastes impacts on water, soil and sediment quality. This project will establish the scientific principles of phosphate stabilisation, which involves the addition of phosphate compounds to mine wastes and soils to permanently contain metals and acid. A solid understanding of this emerging technology is a prerequisite for any sustainable management of mine sites. The study will provide the foundation of future management tools needed by landholders, industry and regulators to remediate mined land and waste repositories.Read moreRead less
Geochemical, physical and microbiological controls on zinc mobility and implications for bioremediation strategies in Western Tasmanian acid mine drainage. We propose to study heavy metal pollution (e.g., zinc, arsenic, iron, tin) and biogeochemical processes operating in acid mine drainage at the abandoned Mt Bischoff tin mine in Western Tasmania. The drainage waters at this site have pH values as low as 2, but contain an extensive and thriving natural biological community. We will evaluate w ....Geochemical, physical and microbiological controls on zinc mobility and implications for bioremediation strategies in Western Tasmanian acid mine drainage. We propose to study heavy metal pollution (e.g., zinc, arsenic, iron, tin) and biogeochemical processes operating in acid mine drainage at the abandoned Mt Bischoff tin mine in Western Tasmania. The drainage waters at this site have pH values as low as 2, but contain an extensive and thriving natural biological community. We will evaluate whether the natural biogeochemical processes operating at Mt Bischoff have the potential to remediate mine waters under the full gamut of climatic conditions, so as to evaluate whether the biota could be exported to other mine sites to help in ameliorating acid drainage problems.Read moreRead less

Effects of environmental change on seafood micronutrients: a SE Asian focus. This project aims to track variability in flows of essential micronutrients through marine food webs, to quantify how environmental changes will affect micronutrient supply to humans in seafood – findings that will be highly significant as governments grapple with increases in both malnutrition and ecological degradation. Expected outcomes: world-first models for accurately estimating nutrient production from SE Asian r ....Effects of environmental change on seafood micronutrients: a SE Asian focus. This project aims to track variability in flows of essential micronutrients through marine food webs, to quantify how environmental changes will affect micronutrient supply to humans in seafood – findings that will be highly significant as governments grapple with increases in both malnutrition and ecological degradation. Expected outcomes: world-first models for accurately estimating nutrient production from SE Asian reef fisheries up to 2050, under conditions of predicted climate change. Major expected benefits: new capacity to plan for food and nutrition security into an uncertain future, for Australia, our region, and beyond; with improvements to human nutrition and health, in accord with UN Sustainable Development Goal 2 (Zero Hunger).Read moreRead less
Aboriginal and non-Aboriginal sex-offenders in Australia: Assessing risk for practice and policy. A key priority of Australian governments is to improve community safety through reducing the risk of sex offenders re-offending after release from prison. This project will assess the validity of tools used to predict the risk of sexual offender recidivism and identify alternate risk assessment tools for Indigenous and non-Indigenous sex offenders.
Parole in crisis? Public opinion on the use of parole. Serious crimes committed by parolees in Australia have brought parole into the public eye. Without concrete evidence, governments often act on the assumption that the public holds punitive attitudes. This project is expected to develop an evidence base to inform policy on parole at a crucial time when governments are under pressure to restrict its use. Three mixed-method studies aim to assess: what public views on parole are; why the public ....Parole in crisis? Public opinion on the use of parole. Serious crimes committed by parolees in Australia have brought parole into the public eye. Without concrete evidence, governments often act on the assumption that the public holds punitive attitudes. This project is expected to develop an evidence base to inform policy on parole at a crucial time when governments are under pressure to restrict its use. Three mixed-method studies aim to assess: what public views on parole are; why the public holds these views; and what influence these views have on policy and practice. The project is expected to make contributions to: creating information strategies that properly inform the public; supporting prisoner reintegration strategies; and shaping criminal justice policies based on informed community feedback.Read moreRead less
