Research using new antennas in the Australian hinterland has reduced background noise and brought us closer to finding a 13-billion-year-old signal
The early Universe was dark, filled with a hot soup of opaque particles. These condensed to form neutral hydrogen which coalesced to form the first stars in what astronomers call the Epoch of Reionisation (EoR).
“Finding the weak signal of this first light will help us understand how the early stars and galaxies formed,” says Dr Christene Lynch from ASTRO 3D, the ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions.
Dr Lynch is first author on a paper published in Publications of the Astronomical Society of Australia. She and her colleagues from Curtin University and the International Centre for Radio Astronomy Research have reduced the background noise in their observations allowing them to home in on the elusive signal.
RMIT researchers call on Melburnians to plant the right plants and create the right homes for native pollinators. They say we’ll get better tomato crops, more flowers and boost urban biodiversity.
As Melbourne’s gardens burst into life after a wet spring, native insects are out looking for flowers and pollen. City gardeners rely on bees, butterflies and other insects to pollinate their plants, which is how flowering plants reproduce and grow fruit or seeds.
But city gardens often don’t have the right types of food and homes for these helpful native bees and flies, with knock-on effects for our gardens and for biodiversity. Urban ecologist Katherine Berthon from RMIT University found that only 43% of flowers in the Melbourne city gardens she studied were being used by bees and other pollinating insects.
A University of Adelaide study shows industry players are open to measures to reduce plastics in seafood – but first they have to understand the problem.
More than 35 percent of fish caught in the waters off southern Australia contain microplastics, and the problem is most acute in South Australia, with plastic found in 49 percent of fish, according to research from the University of Adelaide.
Saving lives after stroke with a small aircraft or ambulance-mounted CT brain scanner
Adelaide company Micro-X (MX1) has started developing a small CT brain scanner that can be fitted in ambulances and emergency aircraft. If successful, the device will allow paramedics and retrieval teams to diagnose and then start treating stroke patients in the golden hour – the first hour after a stroke.
Today Micro-X signed a Project Agreement that will unlock $8 million of funding from a $40 million grant awarded to the Australian Stroke Alliance under the Australian Government’s Frontier Health and Medical Research initiative. The funding will contribute to the development of the scanner for patient imaging trials in 2023.
ARTG listing for revolutionary lightweight x-ray machine
Globally unique new x-ray technology invented and made in Adelaide
Rover is a mobile digital x-ray imaging unit that’s lighter, cheaper, more robust, and more reliable than the competition
Micro-X has miniaturized X-ray tubes using carbon nanotube emitter technology that are one tenth of the weight of conventional glass tubes
Over 250 units operating in 30 countries around the world, first batch of Rover orders for Australia to be shipped.
An ultra-lightweight, highly mobile medical imaging device, the Micro-X Rover, that delivers easier and simpler x-ray imaging for patients and faster workflow for radiographers, has been given the green light by health authorities for sale in Australia.
The inclusion of Rover on the Australian Register of Therapeutic Goods (ARTG) means better imaging solutions for Australians and opens a path to new manufacturing jobs in Adelaide.
“It’s fantastic now that we can really attack our own domestic market here in Australia with our own, highly price competitive, Australian made, proprietary product,” said Peter Rowland, managing director of Adelaide-based firm Micro-X, which invented the technology and developed this game-changing product.
Drive an electric vehicle from Melbourne to Sydney on a single charge
Create lightweight batteries for drones and submarines
Unlock new avenues in aviation and maritime industries
Produce batteries in Australia with Australian lithium, without using cobalt and rare earth minerals.
Simply by adding sugar, researchers from the Monash Energy Institute have created a longer-lasting, lighter, more sustainable rival to the lithium-ion batteries that are essential for aviation, electric vehicles and submarines.
The Monash team, assisted by CSIRO, report in today’s edition of Nature Communications that using a glucose-based additive on the positive electrode they have managed to stabilise lithium-sulfur battery technology, long touted as the basis for the next generation of batteries.
“In less than a decade, this technology could lead to vehicles including electric buses and trucks that can travel from Melbourne to Sydney without recharging. It could also enable innovation in delivery and agricultural drones where light weight is paramount,” says lead author Professor Mainak Majumder, from the Department of Mechanical and Aerospace Engineering and Associate Director of the Monash Energy Institute.
Research reveals how star-making pollutes the cosmos
Animation available, astronomers available in Australia and UK for interview
Galaxies pollute the environment they exist in, researchers have found.
A team of astronomers led by Alex Cameron and Deanne Fisher from the ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) used a new imaging system on at the WM Keck Observatory in Hawaii to confirm that what flows into a galaxy is a lot cleaner than what flows out.
Each reveal the fundamentals of science: energy, waves, light, and the beauty in the natural world in Josef Gatti’s photographs and short films. Please watch these two short clips and consider how you could use them in an online feature: https://bit.ly/2VTGGet; https://bit.ly/37OiiO1
Plankton? Pollen? Sound?
Cells or sound?
Ancient tiles? Bouncing salt?
An alien planet? Or a bubble
The clips and stills are from Phenomena, an ABC series of nine award winning episodes made by Josef Gatti and published through the ABC’s YouTube channel and Facebook and as a half-hour short film on ABC iView. Each film focuses on a force of nature.
Nationwide project aims to map Australia’s favourite predator birds
“I heard the owl scream and the crickets cry.” Macbeth, William Shakespeare.
Is that an owl hooting? Or a car?
Researchers are after volunteers to help map five native Australian owl species, by listening to short recordings made in the bush.
The results will provide important information about the range and numbers of these beloved birds of prey. They will also help researchers develop artificial intelligence (AI) systems to use in a new field of science, known as “eco-acoustics”.
The project is called Hoot Detective, and is produced by ABC Science in collaboration with the Australian Acoustic Observatory (A2O) for National Science Week. It will commence online on Monday 9 August at www.hootdetective.net.au and run until the end of August.
