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.

The first microscopes gave humans the ability peer deep into the microscopic world, allowing us to see cells and microbes in unprecedented detail. Using the latest electron microscopes we are now able to see detail down to single atoms.

In fact, materials scientists can detect impurities in their latest compounds, atom by atom, using powerful electron microscopes aided by sophisticated modelling of what happens when the electron beam hits the material.
Dr Adrian D’Alfonso and a team of theoretical physicists at the University of Melbourne have developed these models and they are already helping groups around the world look at and understand nanomaterials in a way they haven’t been able to before.
Australia’s birds are bright and noisy compared with birds elsewhere, so perhaps it is no surprise they account for over 18 million of the more than 30 million observations in the Atlas of Living Australia; including records from before European settlement.
Now, funded by the Australian National Data Service (ANDS), a team led by spatial ecologist Dr Jeremy VanDerWal of the Centre for Tropical Biodiversity and Climate Change at James Cook University (JCU) is developing a website, known as “Edgar”, to clean up existing records and augment them with reliable observations from enthusiastic and knowledgeable bird watchers.
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.
Melbourne shared in the announcement of the discovery of a Higgs boson-like particle in 2012, and the city is expected to reap millions of dollars in economic benefits brought by the conference at which this discovery was announced.

The announcement that a suspect matching the elusive subatomic particle’s description had been found came at the 36th International Conference on High Energy Physics, held at the Melbourne Convention Centre in July, in a joint announcement with CERN in Switzerland.

In 2012, scientists celebrated at the announcement of the discovery of a Higgs boson-like particle, a subatomic particle that completes our model of how the Universe works.

The announcement was made simultaneously at CERN in Geneva, and to hundreds of physicists gathered in Melbourne for the International Conference on High Energy Physics.
“As scientific discoveries go, this is up there with finding a way to split the atom,” says Prof Geoff Taylor, director of the ARC Centre of Excellence for Particle Physics at the Terascale (CoEPP).
More than 50 different environmental measures routinely collected by Australia’s national ocean research vessels—including sea surface temperature, dissolved oxygen concentration, and salinity—can now be accessed online almost as they are recorded.
The data is incorporated, often automatically, into predictive meteorological and ocean models, improving their accuracy. “So we end up with an improved representation not only of the weather but of processes like large scale ocean circulation or the state of the seas during tropical cyclones,” says Dr Roger Proctor, director of the e-Marine Information Infrastructure Facility of Australia’s Integrated Marine Observing System.
Melbourne-based manufacturing company RMAX is working with CSIRO to make a sustainable, and biodegradable, version of a product involved in the life-cycle of many of the things we buy.

They hope to cut the environmental impact of the nine thousand tonnes of expanded polystyrene (EPS) that ends up in Australian landfill every year. Continue reading Next generation packaging→
