Academy recognition
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
Fresh Science 2013
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
Made to order: printing of live cells
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.
A new art form from nanotech
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.
Light work makes for a better drop
New Australian technology will enable real-time monitoring of wine throughout its fermentation and maturation process, reducing spoilage and improving quality.
The “Smart Bung” technology has been pioneered at the University of Adelaide by the Institute for Photonics & Advanced Sensing (IPAS) and the School of Agriculture, Food and Wine (SAFW). The work is led by Prof Tanya Monro, Director of IPAS.
An optical fibre sensor incorporated into the bung of a wine cask can detect substances that might cause the wine to spoil. The optical fibres have tiny holes that take up minute samples of the wine. The sensor shines light through the fibres to determine the concentration of certain important chemicals, such as hydrogen peroxide and sulphur dioxide—all without having to open the cask. The system will enable continuous, real-time cask-by-cask monitoring and an immediate response if problems are detected.
Micro muscles bend to the task
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
Micro sensors for extreme conditions
Miniaturised sensors are nothing new, but ones made from a combination of silicon carbide (SiC) and the single-layer lattice of carbon atoms known as graphene certainly are. These new sensors are being designed to operate under the harshest of conditions.
Research, led by the Australian National Fabrication Facility’s (ANFF) Queensland node at Griffith University, promises a new generation of tiny microelectromechanical system (MEMS) sensors that are sensitive to very low forces, can work at high frequencies and in extreme conditions—above 1,000°C or under an acceleration of several times g—and are resistant to chemical attack.

Light-powered chip smashing records
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.
Australian Synchrotron helps its big brother in Geneva
New technologies and techniques needed for the next upgrade of the Large Hadron Collider (LHC) are being tested at the Australian Synchrotron.
In 2013, the LHC will shut down for enhancements that will enable it to generate a reliable supply of Higgs-like particles.
