As partners in the $329 million Blue Economy CRC announced in Launceston
Macquarie University engineers will
develop new technologies for ocean
infrastructure as part of the Blue Economy Cooperative Research Centre
announced by Karen Andrews, the Minister for Industry, Science and Technology.
Economy CRC will drive an evolution in marine-based industries, unlocking
enormous economic, environmental and technological benefits in aquaculture and
renewable energy in Australia’s maritime zone.
As partners in the $245 million SmartSat CRC announced in Adelaide this morning.
research and industry partners are contributing $190 million investment in cash
and in kind to the new Cooperative Research Centre for Smart Satellite
Technologies and Analytics, and the Australian government is contributing a
further $55 million. The CRC is led by the University of South Australia.
new generation of low-cost smart satellite technology has the potential to
enhance agriculture, mining, communication and national security,” says
Associate Professor Sam Reisenfeld, who leads Macquarie University’s
contribution to the CRC.

An international team of researchers led out of Macquarie University has demonstrated a new approach for converting ordinary laser light into genuine quantum light.
Their approach uses nanometre-thick films made of gallium arsenide, which is a semiconductor material widely used in solar cells. They sandwich the thin films between two mirrors to manipulate the incoming photons.
The photons interact with electron-hole pairs in the semiconductor, forming new chimeric particles called polaritons that carry properties from both the photons and the electron-hole pairs. The polaritons decay after a few picoseconds, and the photons they release exhibit distinct quantum signatures.
The teams’ research was published overnight in the journal Nature Materials.

Males have to make less of an effort to mate with promiscuous female fruit flies, making the quality and quantity of their semen all the more important in the competition to fertilise the females’ eggs.
This also leads to male flies repeatedly mating with the same female, according to a paper published overnight in Nature Communications, by researchers from Macquarie University, the University of Oxford and the University of East Anglia, who looked into the eyes of thousands of fruit flies.

Firestorms are a nightmare for emergency services and anyone in their path. They occur when a bushfire meets a ‘perfect storm’ of environmental conditions and creates a thunderstorm.
Dr Rachel Badlan and Associate Professor Jason Sharples are part of a team of experts from UNSW Canberra and ACT Emergency Services that has found the shape of a fire is an important factor in whether it will turn into a firestorm.
Fires that form expansive areas of active flame, rather than spreading as a relatively thin fire-front, are more likely to produce higher smoke plumes and turn into firestorms, the researchers found.
This finding is being used to underpin further development of a predictive model for firestorms. The model was trialed in the 2015 and 2016 fire seasons by the ACT Emergency Services Agency and the NSW Rural Fire Service, and now forms part of the national dialogue around extreme bushfire development.

Researchers have identified over 5,700 new proteins in rice and are calling for a global effort to find the remaining missing proteins, in a new study co-authored by Macquarie University.
The international team of scientists from Australia, Iran and Japan say there’s an estimated 35,000 proteins encoded by the rice genome, and yet we still don’t have experimental evidence for 82 per cent of them.
This is important because rice is the major food source for more than half the world’s population, and in order for it to grow in warmer climates and with less water we will need to better understand rice at the molecular level. [continue reading…]
“Your sightings, no matter how long ago they happened, will help us work out how many sawfish there used to be, how many remain, and how we can help them recover,” says Dr Barbara Wueringer, a zoologist and the director of Sharks and Rays Australia (SARA).

Forty years ago, sawfish were regularly seen off Sydney and the east coast, and Perth and up the west coast. Today they’re rarely seen outside of the Gulf of Carpentaria, NT and the Kimberley.

Do you love or loathe your creepy-crawly house guests? Are you an insecticide at the ready kind of person? Or do you take a more live and let live approach?
Researchers from Macquarie University and the University of Sydney want to know about the insects and spiders living in and around your home, how you feel about them, and what you do to control them. [continue reading…]

Researchers from Swinburne University of Technology are collaborating with experts from the Defence Materials Technology Centre, MacTaggart Scott Australia, United Surface Technologies and the Defence Science and Technology Group to advance the new technology.
Researchers from The University of Western Australia have developed a winning medicine formula that makes bad-tasting medicine taste nice, making it easier to treat sick children.
The UWA study published by the journal Anaesthesia tested 150 children and found that the majority of children who were given the new chocolate-tasting medicine would take it again, unlike the standard treatment, while they still experienced the same beneficial effects.
UWA Clinical Senior Lecturer Dr Sam Salman said the poor taste of many medicines, such as Midazolam, a sedative used prior to surgery, presented a real difficulty in effectively treating children.
Bacteria that turn sugar into hydrogen are being engineered by Macquarie University researchers who received a $1.1 million grant from ARENA, the Australian government’s renewable energy agency.
“There’s global interest in using hydrogen gas to produce electricity in hydrogen fuel cells, for example to power vehicles, heat buildings or provide electricity for industry,” says Professor Robert Willows, who is one of the project leaders. “It’s a clean and efficient energy source.”
While 95 per cent of the hydrogen used worldwide currently is produced from fossil fuels, increasingly people are looking at how to produce hydrogen from renewables.
