Making waves in a wind tunnel

We know the Southern Ocean plays a big role in our climate, but there’s much to learn about how and where clouds form over the sea, how they influence global temperatures, and how the wind affects cloud formation and how much carbon dioxide our oceans can absorb.

Now a 60m ‘wave pool in a wind tunnel’ built by Associate Professor Jason Monty is allowing researchers from The University of Melbourne, Swinburne, and Monash University to find out.

“We know that small eddies at the surface of the ocean affect how evaporation occurs and gasses are exchanged, but this turbulence is not included in climate models, as no one has been able to measure it,” Jason says.

Seeing through bushfire smoke

Cool thinking by an Australian defence scientist while a bushfire bore down on his family home provided first responders with clearer satellite images of the blaze, and likely prevented further devastation.

The Sampson Flat bushfires in South Australia claimed the lives of around 900 animals, destroying 27 houses along with other property in January 2015.

Chris Ekins evacuated his family, but while preparing to protect their home he heard on local ABC radio that aircraft were having difficulty seeing through the smoke.

Eye, repair yourself

Gene therapy clinical trials are underway to treat one of the leading causes of blindness in the developed world.

The treatment for wet age-related macular degeneration (more advanced than dry macular degeneration) will hopefully be available to patients within three years, says the team at the Lions Eye Institute in Western Australia.

They’re using a modified virus to carry a gene into the cells at the back of the eye. The delivered gene encourages these cells to continuously secrete medication to treat the problem.

A path to large-scale manufacturing

The development of a two-quantum bit (qubit) logic gate in silicon heralds the possibility of moving quantum computers from experimental lab to large-scale manufacture much faster than other global research efforts.

Scientia Professor Andrew Dzurak and his team have created a two-qubit gate – a critical component, which allows qubits to talk to each other and will form the basis for a quantum computer chip.

It’s an advance that the UK’s premier physics magazine, Physics World, declared one of the top 10 breakthroughs of 2015.

Designing the coolest and most efficient tropical houses

Traditional buildings in Indonesia make use of ‘passive’ cooling techniques. Being well ventilated, raised off the ground, and with shady verandas, their design allows them to stay cool in a tropical climate without air conditioning. The classic timber ‘Queenslander’ house also follows a similar design.

Now architects and engineers from both countries are getting together to compare notes on such designs and materials.

Taking autoimmune disease personally

More than 1.2 million Australians have an autoimmune disease. But any two people may experience it very differently, even if their disease has the same name.

Unlike infectious diseases, autoimmune diseases are not passed from person to person. They are our bodies fighting themselves, making every person’s disease unique.

“A lot of clinical trials fail as they treat all patients with a certain ‘disease’ as one big group,” says Professor Carola Vinuesa, from the National Health and Medical Research Council Centre for Research Excellence in Personalised Immunology at The Australian National University.

Flying whale sharks

Short periods of flapping wings alternating with long, gliding descent helps birds preserve energy in flight. Now researchers have discovered that sharks and seals can use the same technique to glide through the ocean.

Murdoch University’s Dr Adrian Gleiss led a team that attached accelerometers to whale sharks, white sharks, fur seals, and elephant seals.

They found that all four species performed the characteristic undulating flight of birds and bats, with periods of active, upwards propulsion alternating with slow, passive, gliding descents.

Cool Kids goes bush – helping rural children with anxiety

Just under half the children in Australia with a mental health issue aren’t receiving the appropriate treatment, and one third of their parents say the main impediment is a lack of access to treatment options.

“We’ve got all these great programs that we know work, but kids in rural Australia have just not been getting access to them,” says Dr Lauren McLellan, a clinical psychologist and Research Fellow at the Centre for Emotional Health.

Foldable batteries and scaffolds for muscle

Patented University of Wollongong technology is being used to create foldable batteries and textiles that are super strong, light, can repel water, and act as sensors.

Australian company Imagine Intelligent Materials has a commercial licensing deal to use the graphene manufacturing technology, developed at the ARC Centre of Excellence for Electromaterials Science (ACES) at the University of Wollongong.

Reading the whispers of MH370

A communication ‘heartbeat’ has helped narrow the search area for missing Malaysia Airlines flight MH370. The flight disappeared in March 2014 with 239 people on board.

“Essentially we’ve had to develop, and measure the accuracy of, a way to use the extra data collected during the satellite communication,” says Dr Neil Gordon, Head of Data and Information Fusion at the Defence Science and Technology Group in Australia.

“The main communication data is a ‘heartbeat’ signal every hour, asking the aircraft ‘are you there?’ When it says ‘yes,’ a little bit of information attached to that message is captured, giving hints on the speed and direction the plane is travelling, and the distance between the satellite and the aircraft,” Neil says.
