Angela Moles: Rocking the ecological boat
Until recently, everyone thought that the biologically active candidates for new drugs would mainly be found in high-biodiversity tropical forests.
Andrea Morello: Quantum computing becomes more than just spin
People have speculated about the potential of quantum computers for decades—how they would make child’s play of constructing and testing new drugs, searching through huge amounts of data and ensuring security of information.
This scenario may be coming true in a high-tech basement at the University of New South Wales.

Small devices to fight a big disease
Detection of dangerous water-borne pathogens will soon be much easier, thanks to advances using microfluidic systems developed at the Melbourne Centre for Nanofabrication (MCN), the Victorian node of the Australian National Fabrication Facility (ANFF).
Microfluidics deals with the control and manipulation of fluids in tiny, constrained volumes, in order to perform scientific tasks. The advantages in such systems centre around the cost and effort savings associated with miniaturisation and automation.

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.
Harnessing waste energy to power factories
Manufacturers are looking for ways to make their factories more sustainable, but before whacking a solar panel on the roof, they’ve got to plan carefully.
University of New South Wales researcher Assoc Prof Sami Kara says production lines need a steady supply of electricity, and if the sun goes behind a cloud, businesses get hit with penalty rates for suddenly drawing more energy from the grid.
Alice Springs—gateway to the stars
Scientists are using the unique advantages of Australia’s Red Centre to conduct high-altitude balloon flights for astronomical research. The clear air and low population of central Australia make it the ideal location for balloon-based research.
For most types of astronomy, observatories are typically built high on the tops of mountains, far out in space or high in the sky, dangling from 150-metre-tall helium balloons. Continue reading Alice Springs—gateway to the stars
Doubling up pays dividends in exoplanet hunt
“Twice the resolution and all the photons,” is Prof Chris Tinney’s new catchphrase. It refers to new equipment being commissioned on the Anglo-Australian Telescope to hunt for planets beyond our Solar System (exoplanets). Chris, from the University of New South Wales, is a leader of the Anglo-Australian Planet Search (AAPS), which has found 32 exoplanets, almost 10% of the worldwide total, since 1998.
A Doppler shift in a star’s light spectrum often indicates the presence of planets. Unlike previous equipment, which frequently missed some of that light, the new system uses a cluster of optical fibres to gather all the starlight, boosting efficiency and doubling the Doppler precision.

Crashing helicopters for safety
Mathew Joosten crashes several helicopters a day—without any deaths or injury. He uses computer simulation.
A research student of the Cooperative Research Centre for Advanced Composite Structures, Mr Joosten has designed ‘virtual crash test’ software to help accelerate the development of safety systems.
Computing with a single electron
Australian engineers and physicists have developed a ‘single electron reader’, one of the key building blocks needed to make a quantum computer.
Quantum computers will use the spin, or magnetic orientation, of individual electrons for their calculations. And, because of the quantum nature of electrons, quantum computers could be exponentially faster at certain tasks than traditional computers.In order to employ electron spin, a quantum computer needs both a way of changing the spin state (writing information) and of measuring that change (reading information). Together these two form a quantum bit or qubit – the equivalent of the bit in a conventional computer.
