A farmer whose onion paddock is hit by the fungal disease “white rot” faces the loss not only of that crop but of productive use of the field for several years. Relief could be at hand, however, thanks to a novel granulated fungicide now being tested in the field in Victoria.

“In the case of white rot, there is no existing commercially acceptable treatment and if a farmer has an infestation in their field they can’t use it for onions or similar crops for up to 15 years,” says Anthony Flynn, managing director of the agricultural chemical research company Eureka! AgResearch. “They’ve just had to move the crop on to the next paddock.”
Water sampling devices are keeping watch around the clock for toxic discharges into Melbourne’s creeks and stormwater drains, thanks to Victorian researchers at the Centre for Aquatic Pollution Identification and Management (CAPIM), based at the University of Melbourne.

And, they are also developing a new range of aquatic critter-containing sensors.
The Autonomous Live Animal Response Monitors (ALARM) will house live molluscs, insects or shrimps and transmit images and data to scientists via the web, in the ultimate test of a creek’s health. Continue reading Live streaming for healthy waterways→
Manufacturers are looking for ways to make their factories more sustainable, but before whacking a solar panel on the roof, they’ve got to plan carefully.

University of New South Wales researcher Assoc Prof Sami Kara says production lines need a steady supply of electricity, and if the sun goes behind a cloud, businesses get hit with penalty rates for suddenly drawing more energy from the grid.
Dr Tracy Ainsworth’s research is changing our understanding of the tiny coral animals that built Australia’s iconic Great Barrier Reef. Tracy and her colleagues at James Cook University in Townsville have found that the process of coral bleaching is a far more complex than previously thought, and begins at temperatures lower than previously considered. And she’s done so by applying skills in modern cell biology which she picked up working in neuroscience laboratories.

Her achievements won her a $20,000 L’Oréal Australia For Women in Science Fellowship in 2011, which she is using to study the low light, deep water reefs that underlie tropical surface reefs at depths of 100 metres or more. Continue reading The complex life of coral→
The Earth is losing species and ecosystems fast, but figuring out the best response is not easy when information, time and money are scarce.

Dr Eve McDonald-Madden is using maths to help governments and others make tough decisions on how best to use limited resources to preserve ecosystems under threat.
The young Australian scientist helps to save species, not by going out into the field, but by analysing the data other people have collected on endangered species. Continue reading The mathematics of conservation→
Australia’s scientists are among the most productive in the region. That’s the picture that emerges from the Nature Publishing Index 2011 Asia-Pacific released in March 2012

Australia ranks second only to Singapore in terms of science output per capita and per scientist in the Index, which measures the publication of research articles in Nature research journals by Asia-Pacific nations and institutions. Singapore and Australia are also first and second in the Asia-Pacific respectively in terms of GDP per capita. Continue reading Australian science’s place in Asia→
A chance finding has led to the first new chlorophyll discovered in 67 years, opening up possibilities for biofuel and food crops to use sunlight more efficiently.

Baker’s yeast could soon be turning sugar cane into jet fuel. Dr Claudia Vickers from the Australian Institute for Bioengineering and Nanotechnology (AIBN) at the University of Queensland leads a team studying strains which already produce ethanol, industrial chemicals and pharmaceuticals.
The researchers want to use the yeast strains S. cerevisiae to make isoprenoids, chemicals traditionally used to make pharmaceuticals and food additives, but which can also serve as fuel.
The idea is to give the yeast new functions, so they can consume sucrose from cane sugar and produce isoprenoid products, which can be used to replace or supplement traditional jet fuel, without modifying existing aircraft engines or infrastructure.
Claudia’s lab was originally looking at the gut bacteria E. coli, which could also be used to produce isoprenoids, but the yeast is now looking more promising.
Other research groups at The University of Queensland and James Cook University are looking to develop aviation fuel from algae and the oilseed tree Pongamia, both of which can be grown without competing with traditional food crops for land or water.
The University’s sustainable aviation fuel initiative has attracted several backers including Boeing, Virgin Australia, Mackay Sugar, Brisbane-based IOR Energy, and the US-based green energy company Amyris. It is funded by the Queensland State Government.

Turning to mathematics to allow us to make smarter conservation decisions.
The diversity of life on Earth underpins the global economy. But we’re losing biodiversity at an unprecedented rate and human-induced climate change will threaten more species—up to 37 per cent of the plants and animals with which we share the world.
