Knee reconstructions may lead to more problems later in life than non-surgical rehabilitation, researchers have found.

A team led by Dr Adam Culvenor from La Trobe University looked at health outcomes for athletes with damaged anterior cruciate ligaments (ACL) – a devastating injury, particularly common among footballers.

ACL injuries require lengthy rehabilitation and up to 12 months on the sidelines. However, many athletes also opt for surgery to reconstruct the torn ligament in the hope that this will get them back to sport sooner and prevent the development of knee arthritis.

Tests on new designs for next-gen solar cells can now be done in hours instead of days thanks to a new system built by scientists at Australia’s Monash University, incorporating 3D-printed key components.

The machine can analyse 16 sample perovskite-based solar cells simultaneously, in parallel, dramatically speeding up the process.

The invention means that the performance and commercial potential of new compounds can be very rapidly evaluated, significantly speeding up the development process.

Fish faeces reveals which species eat crown-of-thorns

Australian Institute of Marine Science, Media releases

Great Barrier Reef research finds the destructive starfish is eaten more often than thought.

Crown-of-thorns starfish are on the menu for many more fish species than previously suspected, an investigation using fish poo and gut goo reveals.

The finding suggests that some fish, including popular eating and aquarium species, might have a role to play in keeping the destructive pest population under control.

Galaxies grow large by eating their smaller neighbours, new research reveals.

Exactly how massive galaxies attain their size is poorly understood, not least because they swell over billions of years. But now a combination of observation and modelling from researchers led by Dr Anshu Gupta from Australia’s ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) has provided a vital clue.

Semi-transparent solar cells that can be incorporated into window glass are a “game-changer” that could transform architecture, urban planning and electricity generation, Australian scientists say in a paper in Nano Energy.

The researchers – led by Professor Jacek Jasieniak from the ARC Centre of Excellence in Exciton Science (Exciton Science) and Monash University – have succeeded in producing next-gen perovskite solar cells that generate electricity while allowing light to pass through. They are now investigating how the new technology could be built into commercial products with Viridian Glass, Australia’s largest glass manufacturer.

Hot qubits made in Sydney break one of the biggest constraints to practical quantum computers

Media releases

A proof-of-concept published in Nature promises warmer, cheaper and more robust quantum computing. And it can be manufactured using conventional silicon chip foundries.

Most quantum computers being developed around the world will only work at fractions of a degree above absolute zero. That requires multi-million-dollar refrigeration and as soon as you plug them into conventional electronic circuits they’ll instantly overheat.

But now researchers led by Professor Andrew Dzurak at UNSW Sydney have addressed this problem.

Additions to resource industry underwater robots can boost ocean discoveries

Underwater robots are regularly used by the oil and gas industry to inspect and maintain offshore structures. The same machines could be adapted to gather extra scientific information, thus boosting environmental and resource management capabilities, an Australian-led study has revealed.

Scientists from around the globe, led by Dianne McLean and Miles Parsons from the Australian Institute of Marine Science (AIMS), are urging closer ties between industry and researchers to maximise the use of the underwater robots, known as remotely operated vehicles (ROVs).

In a paper published in the journal Frontiers in Marine Science, they identify a range of instruments that can be easily added to the craft, including cameras, audio recorders and sample collectors.

A literal “trick of the light” can detect imperfections in next-gen solar cells, boosting their efficiency to match that of existing silicon-based versions, researchers have found. 

The discovery opens a pathway to improved quality control for commercial production.

On small scales, perovskite solar cells – which promise cheap and abundant solar energy generation – are already almost as efficient as silicon ones. 

However, as scale increases the perovskite cells perform less well, because of nanoscale surface imperfections resulting from the way they are made.

As the number of unwanted tiny lumps and bumps grows, the amount of solar power generated per square centimetre drops off. 

Now, however, Australian researchers have come up with a solution – using a camera.

Leaky water pipes found at high speed using AI

Fresh Science

Researchers have been able to pick a water leak within 1 percent of its location within seconds.

Artificial intelligence combined with pressure waves has been used to find faults in major water pipelines faster and more cheaply than existing methods.

Jessica Bohorquez and researchers from the University of Adelaide have developed a system that utilises the deep learning capability of AI and has dramatically increased the chances of detecting cracks in underground pipes.

“In a country where water is scarce, there is an urgent need for this type of technology,” says Jessica.

ATSE Australia health tech in 2030

Australia’s healthcare system must quickly incorporate technologies including remote consulting, wearable monitors and full digitisation if it is to meet the challenges of the coming decade, an investigation by the Australian Academy of Technology and Engineering (ATSE) has found.

Smart devices that check temperature and oxygen levels, health appointments via Skype, e-health records that tell hospitals which antibiotics patients are allergic to, digital disease surveillance, and modelling that pinpoints regions showing signs of outbreaks – these are new health technologies that are desperately needed as the world responds to the coronavirus pandemic.
