The Great Barrier Reef is big, so big that scientists need your help to track its health.
We’re inviting every Australian to dive through their computer screens into the Reef by taking part in Virtual Reef Diver—the ABC’s online citizen science project for National Science Week and the International Year of the Reef.
“We need the community to pitch in to help us classify thousands of underwater images of the Reef,” says spatial scientist and project leader Dr Erin Peterson from Queensland University of Technology.
“Tell us whether you can see coral, algae or sand, and we’ll be able to get an estimate of the coral cover in that image.”
New lab designed to meet the demands of the next wireless revolution

Macquarie’s School of Engineering today announced a partnership with semiconductor company Analog Devices, Inc. (Nasdaq: ADI) to launch the Macquarie and Analog Devices Teaching and Research Laboratory (MADTRL).
The new teaching and research lab will bring industrial experience into Macquarie University, to better prepare the next generation of engineers.
“Traditionally, undergraduate engineering education has been structured around classroom theory, laboratory exercises, and a relatively disconnected industry-placement or internship system,” says the School of Engineering’s Professor Michael Heimlich.
“Similarly, Masters and PhD work is typically done in an academic setting with inputs and arms-length interactions with the ‘real world’ at best.”
Many emerging applications ranging from 5G mobile networks to low Earth orbit satellite constellations will require new design paradigms to meet their technical needs and cost constraints.
Analog Devices hopes this partnership will help develop the next generation of microwave and millimetre-wave integrated circuit (MMIC) designers to meet the demand.
“Macquarie University has a history of world class MMIC design and modelling expertise,” says Analog Devices’ Senior Director of Engineering, John Cowles.
“Bringing these technical skills closer to real product development is critical towards accelerating the introduction of next generation technologies into emerging high frequency applications. The merging of design innovation with world class manufacturing is what makes this partnership so exciting.”
We can’t cram any more processing power into silicon-based computer chips.
But a paper published in Nature overnight reveals how we can make electronic devices 10 times smaller, and use molecules to build electronic circuits instead.

We’re reaching the limits of what we can do with conventional silicon semiconductors. In order for electronic components to continue getting smaller we need a new approach.
Molecular electronics, which aims to use molecules to build electronic devices, could be the answer.
But until now, scientists haven’t been able to make a stable device platform for these molecules to sit inside which could reliably connect with the molecules, exploit their ability to respond to a current, and be easily mass-produced.
An international team of researchers, including Macquarie University’s Associate Professor Koushik Venkatesan, have developed a proof of concept device which they say addresses all these issues.
Melbourne scientists have discovered a unique brain signal that will act as a homing device, making deep brain stimulation surgery for Parkinson’s disease and other conditions more accurate, more effective, and less confronting for the patient.
Deep brain stimulation has transformed the lives of people with Parkinson’s disease by reducing their tremors and other symptoms. Surgeons insert electrodes to stimulate a tiny part of the brain—the size of a grain of rice. To get the best results the patient has to be awake. And that’s scary for many patients. Now they can sleep through the surgery.
Bionics Institute clinicians and researchers have recorded and studied the brainwaves of 19 patients during surgery—14 with Parkinson’s disease and five with a condition called essential tremor. They discovered that the part that they’re targeting produces a unique brain signal that can be used to guide the surgeon.
This discovery will enable the surgery to be performed without the need for the patient to be awake.
How are insects responding to rapid climate change?

Damselflies are evolving rapidly as they expand their range in response to a warming climate, according to new research led by Macquarie University researchers in Sydney.
“Genes that influence heat tolerance, physiology, and even vision are giving them evolutionary options to help them cope with climate change. Other insects may not be so lucky,” says Dr Rachael Dudaniec, lead author of the paper.
The study, published in Molecular Ecology today, investigated the genetics of an insect’s capacity to adapt and survive in a changing world by looking at the blue-tailed damselfly (Ischnura elegans) in Sweden.
We’re looking for a science communicator to join our team at Science in Public. We need someone who is organised, loves science and wants to help scientists get their work into the public space.

Monash engineers have designed, printed, and test-fired a rocket engine.

The new rocket engine is a unique aerospike design which turns the traditional engine shape inside out.
Two years ago, Monash University researchers and their partners were the first in the world to print a jet engine, based on an existing engine design. That work led to Monash spin-out company Amaero winning contracts with major aerospace companies around the world.
Now a team of engineering researchers have jumped into the Space Age. They accepted a challenge from Amaero to design a rocket engine, Amaero printed their design, and the researchers test-fired it, all in just four months. Their joint achievement illustrates the potential of additive manufacturing (or 3D printing) for Australian industry.
