Link between Omega-3 and Alzheimers “Previous research has suggested that there is a link between low levels in the brain of the omega-3 fatty acid DHA and Alzheimer’s disease,” explains project leader Professor Leigh Ackland (School of Life and Environmental Sciences). The researchers found that when the level of DHA in neuronal cells (the cells responsible for transmitting signals in the brain) drops, the level of zinc rises. “The higher levels of zinc can be toxic, resulting in cell death. This type of cell death is a key feature of neurodegenerative diseases, including Alzheimer’s.” “We believe that having omega-3 fatty acids in the diet helps keep the levels of zinc in the brain in balance and helps prevents the increase in levels that triggers cell death,” says Professor Ackland, adding “to the best of our knowledge this is the first time a direct link has been demonstrated between the levels of DHA and zinc in neuronal cells.” “Alzheimer’s disease is a complex disorder and it is unclear what causes it, although dietary factors are implicated in its development. Our work provides insights into how fatty acid nutrition may prevent the development of Alzheimer’s and could lead to new treatments that prevent zinc-induced brain damage,” says Professor Ackland.

LES student wins prestigious Australasian Hydrographic Society education award
The title of his PhD research project being undertaken is ‘Understanding demersal fish-habitat associations using video observations and sonar imaging’. Supervised by a team led by Daniel Ierodiaconou (School of Life and Environmental Sciences), the project utilises the recent advances in underwater remote sensing (such as acoustic positioning, multibeam sonar and remotely operated underwater video) to generate detailed data to investigate the spatial relationships between the seafloor and marine coastal fishes in southwest Victoria. The group’s achievements have been previously recognised by the Australian Hydrographic Society in 2006 with the presentation of a Scientific and Technical Achievement Award for their development of new techniques for coastal habitat mapping. Jacquomo is using predictive modelling techniques to get a greater understanding of these relationships. This information is essential to better manage these vulnerable, rare and ecologically important communities. The funds provide the opportunity for Jacquomo to present his work at the GeoHab (Marine Geological and Biological Habitat Mapping) Conference in Wellington, New Zealand in May, and to the Hydrographic board in Sydney later in the year.
Tracking the health of estuaries Engaged by the Department of Sustainability and Environment, Professor Gerry Quinn, Dr Adam Pope and Dr Jan Barton (School of Life and Environmental Sciences) will trial the Index on estuaries across the Victorian coastline. Professor Quinn says the index considers issues such as physical form, hydrology, water quality, sediment, flora and fauna, and connection to the ocean. The Index will help agencies, such as Catchment Management Authorities (CMAs), in management and restoration of estuaries. “They can use it as a report card on the condition of the estuary. We have to make sure it is effective and usable and can be implemented by local agencies,” says Professor Quinn. The project team are currently working with CMAs across the state, and Melbourne Water, to implement the trials. At least 20 estuaries will be included in the trial but the specific locations have not yet been confirmed.
A Melbourne landmark finally tells its story
Dr de Jong’s book tells the story of architect William Wilkinson Wardell’s 1889 design for the ‘Convent and School, Kew’ in Melbourne, now at the heart of Genazzano FCJ College. Wardell is one of Australia's most important nineteenth century architects. His design was impressive, and though only partly realised, has resulted in a Melbourne landmark. It is 120 years since work on the building began, but Dr de Jong believes many of the challenges faced at that time are relevant today. “As well as the financial challenges faced by the client, the FCJ Sisters, there were environmental challenges with the school affected by both bushfires and floods. The building was designed to be sustainable, well ventilated, sensitively orientated and water wise - two million gallons of water was stored on-site, gravity fed from the tower to the bathrooms and lower levels.” While the book is a celebration of history, Dr de Jong hopes it will positively influence how people see and experience their surroundings. “I hope readers of my book will learn to look at buildings differently, with a better understanding of what goes into a building, from the vision, to the design, costing and challenges of realising the built form; I hope they will also learn to look with new eyes at our built environment, both the old and the new,” she says.
Biomedical researcher receives Ramaciotti Foundation grant
Dr Suphioglu’s research is aimed at understanding the molecular properties of major peanut allergens, which will permit the future development of safer and more effective reagents for peanut allergy diagnosis, prevention and treatment. “Receiving this grant will allow us to contribute towards the purchase of an expensive but fundamental piece of research equipment. As a result, our research could significantly reduce the economic, physical and emotional burden of this disease on our society,” said Dr Suphioglu. The Ramaciotti Foundations are collectively one of the largest private contributors to biomedical research in Australia, providing assistance to areas such as molecular biology, genetics and immunology, totaling $2.5 million of support in 2009.

Hot Research Breakfast Geelong Researchers at Deakin are developing new light magnesium alloys that promise to benefit the transport sector in terms of reduced carbon footprints and increased performance. In his talk, Development of a new light metal alloy, Associate Professor Matthew R Barnett outlined their research in this area. Efficient conversion of sunlight into electrical energy is of great technological importance for modern society. Dr Frederick Ochanda said their work aims to close the enormous gap in efficiency between man-made solar cells and their natural equivalents by exploiting nano-technology. He explained how this work involves application of nanocomposites, in his presentation Nanotechnology creating new materials for solar cells applications. Many attempts have been made to apply automotive industrialised techniques to domestic housing manufacturing. However, success has been limited largely due to the lack of holistic understanding throughout the design team, on manufacturing methods, failure to integrate building services and a lack of implementing environmental performance. Associate Professor Mark B Luther examined these issues in his talk, Sustainable manufactured housing in Geelong.
Hot Research Breakfast Melbourne The health benefits of omega-3 fatty acids from fish oil are well established. In fact, a billion dollar market exists for these compounds in nutritional supplements, functional foods and pharmaceuticals. In his presentation, Advances in Omega-3 Biotechnology, Professor Colin Barrow described some commercially useful novel production and delivery technologies for these fatty acids. Recent discoveries on Victoria’s sea floor have revealed previously unknown underwater gardens and submerged river systems and lagoons that would have supported aboriginal communities over 10,000 years ago. In his talk, Beneath the surface: Understanding Victoria’s seascape ecology, Dr Ierodiaconou looked at their findings and how they will redefine resource assessment, conservation planning and improve fisheries management. Internet crimes can result in serious consequences such as disrupting critical infrastructure; causing significant financial losses; and threatening public life. Although a number of countermeasures and legislations against internet crimes are developed, the crimes are still on the rise. One critical reason is that researchers and law enforcement agencies still cannot answer a simple question easily: who and where is the real source of internet crimes? This was the focus of Professor Wanlei Zhou’s talk, Finding the real source of internet crimes. Related news story Video footage related to Daniel's research
LES researcher wins Australian Research Fellowship
Unsustainable fishing practices have led to increased pressure on aquaculture (fish farming) to meet the shortfalls in the supply of fish, which are the main source of many essential omega 3 fatty acids. However, these fish have special nutritional requirements and need to be fed fish oil so they still contain high levels of omega 3. The problem is that current fish oil is derived from the already over-exploited wild fish stock – a situation that is environmentally and economically unstable, likely leading to a collapse of the sector within a few years. Dr Turchini is working on new ways to increase the omega 3 oil contained in farmed fish from within. He is looking at innovative natural methods of producing fish still rich in omega 3 fatty acids without using fish oil. “I am looking at the basic biology of fish,” he says. “It is changing the fish from within – triggering their dormant capability of transforming fatty acids available in vegetable oils into the good ones.” Dr Turchini says in the last two years he has received fantastic support from many staff of the School of Life and Environmental Sciences and the School of Exercise and Nutrition Sciences, in particular from the two co-investigators of the funded ARC discovery project, Professor Andy Sinclair and Associate Professor Leigh Ackland, and from Dr David Francis and Dr Cenk Suphioglu, who were essential for developing the proposal.

Declining bird numbers in TV spotlight Professor Bennett worked on the research with Professor Ralph Mac Nally and Dr Jim Thomson, Monash University; Dr Jim Radford, Deakin University (now with Bush Heritage Australia); and Dr Peter Vesk, University of Melbourne. Their findings were recently published in the international journal Diversity and Distributions. “Climate change, particularly the lack of rainfall, has reduced the quality of habitat available to a wide range of bird species,” Professor Bennett said. “This has compounded the already serious effects of extensive habitat loss, degradation and fragmentation in the region.” Professor Bennett believes lack of food has contributed to the decline in numbers. “The collapse in bird numbers strongly suggests the availability of food has crashed,” he said. “Red Ironbark trees, an important food source for nectar-feeding birds, are flowering less frequently with the drought. In five of the past eight years Red Ironbark eucalypts have flowered little or not at all. “Most worrying, species thought to be secure, such as the Red Wattlebird and the Laughing Kookaburra, have declined as much or more than species already considered endangered. ” “We can’t change the climate,” Professor Bennett said, “but we can do much more to protect and improve the quality of habitats for our native wildlife. “This means careful management of existing native vegetation, including our parks and reserves, and greatly increasing the amount of restoration and revegetation in rural environments. There is much good work being done by Landcare groups and others, but the scale of our restoration actions does not match the scale of the problem.” A transcript of The 7.30 Report story is available on the ABC website Related research paper: Collapse of an avifauna: climate change appears to exacerbate habitat loss and degradation
Student poster prize won at National Conference Sharl’s poster was titled “Priming for resistance against pathogens: cellular responses of Arabidopsis to UV-C radiation” and described his research that is investigating components of the signalling pathways that are induced in the model plant Arabidopsis in response to ultraviolet light. Sharl and his co-investigators are using detailed microscopy, biochemical assays and microarray analysis of gene expression to investigate the impact of ultraviolet light on the response of plants to disease-causing organisms.
Hopkins River Estuary Public Forum

Students imagine the family home of 2050 “The design brief required the students to give a lot of thought to the future: what will the ‘typical’ family be in 2050, the environmental challenges we will be facing, the type of materials we will have available and so on.” The designs, submitted in the form of a short movie, were posted online, giving the students a public audience for their work and challenging them to be imaginative in their presentations. “In the past, a folio was a critical tool for any architect - a big folio full of sheets of A1 paper that you took around to demonstrate your work to clients and employers. Now an architect is just as likely to refer you to their website to see their work, so it is very important for our students to explore how they can present their work by using new technologies. To take a trip into the future and see what the Deakin architecture students think the homes of 2050 will be like visit www.ab.deakin.edu.au/online/futurehouse.
Tall Poppy science award win
Selected on the basis of research achievements and a passion for communicating their work, Dr Ierodiaconou, whose research is in the field of environmental management and ecology, was one of 11 Victorian and Tasmanian scientists under 35 recognised with an award. “The Young Tall Poppy Science Awards recognise scientific achievers who are in the early stage of their careers and already making discoveries,” says Australian Institute of Policy and Science Executive Director, Elektra Spathopoulos. “Not only are they great researchers, they have demonstrated their leadership in communicating science and engaging the public.” Instead of winning prize money, these young scientists gain the opportunity to take their research to school students, teachers and communities around their State and across Australia as part of the Tall Poppy Campaign inspiring a new generation to get passionate about science. The awards were presented at a ceremony held in Melbourne on Thursday 17th September. Numerous former Young Tall Poppy Science Award winners have gone on to win more senior science awards, including Eureka Prizes, Prime Minister’s Prizes for Science and Cosmos Bright Sparks Awards.

Students discover the fun of maths
Forty teams, each consisting of five students and one teacher acting as supervisor and scorer, competed in four events with prizes awarded to the top performers. The contest was run by volunteer staff and students from Deakin’s School of Information Technology. Associate lecturer at Deakin and contest co-organiser Mr John Cameron said although the day was challenging, it was also a lot of fun. “Students and teachers thoroughly enjoyed the contest. It was an exhilarating day of challenging competition comprised of individual and team events designed to test mathematical skills in novel ways. “It provided a wonderful opportunity for members of different schools to experience a day at the Geelong Campus, to exchange ideas on learning and teaching mathematics, and to demonstrate their mathematical knowledge and skill. It was an exhausting day of serious fun.” The event provided an opportunity to show secondary students the variety of careers available from studying maths and encourages students to go on to study maths at tertiary level.

Pieces of Me
Allyson says she has always had a passion for art. “Ever since I can remember, I have loved expressing myself through drawing and painting.” Studying a PhD in forensic and analytical chemistry and expressing herself artistically, while dealing with the problems caused by multiple sclerosis, create challenges that inspire and that Allyson thrives on. “I have always thrived on the challenge. While my research is very analytically and mentally challenging, my artwork involves a test in physically producing whatever creative notion has entered my mind that I want to put on canvas.” “Sometimes I am inspired by things I see or feel, otherwise it may be something that has come to me in a dream. But whatever the motivation, it has always been a unique expression of self.” “I love the fact that anyone can continue to express themselves through art, despite the hardships they may face.” Pieces of Me is now showing at the Karingallery in James Street, Geelong and will be on display until 31st August.
Science and Engineering Super Challenge
Year 9 and Year 10 students from sixteen schools throughout Victoria, including Bendigo, Ballarat, Melbourne and Geelong, took part in a range of hands on science and engineering based activities, showing them science is anything but dull. Wangaratta High School was the winning school on Tuesday 28th July, with Bendigo South East Secondary College taking the honours on Wednesday 29th July. They will both be invited to the Grand Challenge in Bendigo in October to compete against other state winners. Australia has a chronic shortage of scientists and engineers. The Science and Engineering Challenge is a national outreach program conducted by the University of Newcastle with the aim of encouraging junior students to study science at VCE level. The challenge organisers would like to acknowledge the support of sponsors the Australian Constructors Association, WorleyParsons and Rotary.
Research to benefit standard road cars Potential benefits of KERS include improvements to vehicle efficiency and emissions, according to Dr Clive Ferguson (School of Engineering). “KERS is a way of harvesting and storing the energy generated when a vehicle brakes. This stored energy can be used by the vehicle, potentially improving its fuel efficiency and emissions. We also believe there is the potential to improve vehicle handling.” The harvested energy can be stored in various ways, including electrically using batteries – the method mostly used in Formula One to date – or mechanically using a flywheel. Dr Ferguson believes mechanical storage has a number of potential advantages, such as significant savings in weight and space. They are also friendlier for the environment because they remove the need for highly toxic lithium-based batteries. The research will identify the technical difficulties in developing an affordable mechanical KERS for both front and rear wheel drive production vehicles and identify cost effective solutions. “I would like to think that our research may lead to KERS one day being available on standard production vehicles, maybe as an optional extra,” says Dr Ferguson.
