Australian citizen scientists are helping to catch shooting stars in the vast skies of outback Australia and to track the impact of climate change on species in our warming oceans.

Curtin University’s Fireballs in the Sky project invites people to use a smartphone app to record and submit the time, location, trajectory and appearance of meteors they spot.
By triangulating these reports with observations from an array of cameras in remote Western and South Australia, scientists can try to determine where the meteorite may have come from and where it landed.
A radical flotation technology has earned Australia over $4 billion in mineral exports each year by improving mineral particle recovery from wastewater.

Chemical engineer Graeme Jameson, AO, of the University of Newcastle, developed the technology, which was first used in mineral processing plants and is now being applied to other industrial practices.
The 2013 ATSE Clunies Ross Award Winners follow in the footsteps of past winners such as Ian Frazer, inventor of the cervical cancer vaccine; Nobel laureate Barry Marshall, who discovered the bacteria that causes stomach ulcers; Fiona Wood, inventor of spray-on skin; and Martin Green and Stuart Wenham, international leaders in silicon cell technology.

The Australian Academy of Science recognised five individuals for their career achievements in 2013.
The search for dark matter was kicked off by Ken Freeman’s discovery that there wasn’t enough matter to hold spiral galaxies like ours together. Continue reading Academy recognition→
Each year we identify early-career scientists with a discovery and bring them to Melbourne for a communication boot camp. Here are some of their stories. For more information go to freshscience.org.au
Surgeons may soon be able to regrow patients’ nerves, such as those in damaged spinal cords, using technology adapted from the type of inkjet printer most of us have connected to our computer at home.

Researchers at the ARC Centre of Excellence for Electromaterials Science (ACES), University of Wollongong (UOW) node in NSW, have spent the past three years developing the technology to print living human cells—nerve cells and muscle cells onto tiny biodegradable polymer scaffolds. They’ve also developed a special “ink” that carries the cells.
Science and art have combined to bring hand-drawn content for holographic TV and other 3D display technologies a step closer, thanks to research at the Australian National Fabrication Facility’s NSW node (ANFF-NSW) at the University of New South Wales (UNSW).

Unlike the traditional method of making a hologram—which involves reflecting a laser off a real object—the new technique simulates objects within computer software. In a recent test, a virtual, digital hologram file was produced and etched as a 3 mm-wide nanoscale pattern onto a glass plate using ANFF-NSW’s Electron Beam Lithography facility. When laser light was shone through the glass, a 3D hologram sprang into life.
A breakthrough in the electroactive polymers used to make electrically controlled micro “artificial muscles” could be important for future drug delivery in the body, as well as a having a host of other applications.

The new research, conducted at the Australian National Fabrication Facility’s (ANFF) materials node at the University of Wollongong (UOW) in NSW has produced materials which, unlike earlier versions, do not need to be immersed in an electrolyte solution. They are self-sufficient and can even work in air. Continue reading Micro muscles bend to the task→
China has a large community of astronomers awaiting the construction of new telescopes to study pulsars.
When CSIRO pulsar researcher Dr George Hobbs described the high-quality data stored in the Parkes Observatory Pulsar Data Archive—which is openly available—it led to Australian pulsar data being the basis of collaboration between Chinese and Australian pulsar researchers. And they have already published several papers on what they have discovered. The archive is also serving as a major resource in an international search for gravitational waves.
A new computer chip, which uses light instead of electronic signals to process information, could lead to high security, energy-efficient internet links more than 1,000 times faster than today’s networks.
