World’s first nano-scale design to mimic natural blood vessels
New materials developed by University of Melbourne researchers stop potentially deadly blood clots forming in the treatment of many cardiovascular diseases.
Fatemeh Karimi, a postdoctoral researcher, and her team have developed a new material that can be used to create artificial veins and arteries with nano-scale design used as replacements in heart and stroke surgery.
Now we can sample other planets without leaving home Published in Nature Communications
Five to ten million years ago an asteroid smashed into Mars. It created a massive crater and propelled a chunk of ancient Martian crust into space as a new meteorite, which eventually crashed into Africa.
We now know where on Mars that meteorite came from, thanks to a supercomputer-powered technology that allows us to explore the geology of planets without leaving home.
Remains of meteorite NWA 7034, known as Black Beauty, were discovered in Western Sahara in 2011. The story of its creation is told for the first time in Nature Communications by a global team led by researchers from Curtin University, supported by the Pawsey Supercomputer in Perth, Australia, and with colleagues in France, Côte d’Ivoire, and the United States.
Black Beauty is formed of Martian rocks formed nearly 4.5 billion years ago when the crusts of both Earth and Mars were still young. Now we know the source of Black Beauty, researchers can use it to compare the formation of Mars and Earth.
The technology behind the discovery will be used to identify the source of other Martian meteorites but also to identify billions of impact craters on the surface of Mercury and the Moon. More than 300 Martian meteorites have been found on Earth to date.
Aussie astronomers react to NASA Webb first images.
Nearly 40 researchers across Australia are eagerly awaiting data from Webb for their projects. Many of them are available to talk on Tuesday about what they hope to see with Webb and about their reaction to the first pictures
Aussie astronomers available for interviews in Melbourne, Sydney, Brisbane, Perth and Canberra.
They’re using Webb to look for the first stars, the first galaxies, baby planets, massive black holes.
Over the past 30 years, Hubble has transformed science and culture, revealing a Universe of 200 billion galaxies. Webb will see further, solving today’s mysteries and creating new ones.
On Tuesday morning Joe Biden will release ‘the first picture’ then NASA will release a suite of images early Wednesday morning from the James Webb Space Telescope, the successor to Hubble.
Nearly 40 researchers across Australia are eagerly awaiting data from web for their projects. Many of them are available to talk on Tuesday about what they hope to see with Webb and about their reaction to the first pictures.
Much of the Webb data is flowing back to Earth through Tidbinbilla, and some comes from an instrument designed by Peter Tuthill at the University of Sydney. He is relieved and excited. “This is a day I have been looking forward to for a big part of my career. Everything about the Webb is so over-the-top audacious – from the titanic articulated mirror down to its orbit out in the cold voids of interplanetary space.”
Buying and running electric vehicles for business fleets is too costly under Aussie tax rules, say researchers from Griffith University and Monash University.
Their report, published today by the RACE for 2030 Cooperative Research Centre, proposes practical tax changes to support home charging and allow fleet managers to quickly adopt battery electric vehicles (BEVs).
“Some of our recommendations could be implemented right now,” says Griffith University tax law expert and lead researcher Dr Anna Mortimore.
“Because of the turnover of business fleets, these vehicles would start flowing into used car markets within three to four years, so more Australians could afford to go electric.”
Researchers are recruiting volunteers for a clinical trial they hope will improve survival rates for an aggressive form of breast cancer that affects about 1,500 women each year in New South Wales.
The trial will test a new strategy in cancer treatment: using a new therapy to target a ‘defence switch’ on cancer cells that alerts cancer to the threat of chemotherapy.
The trial aims to improve survival rates for patients with triple negative breast cancer, a treatment-resistant form of cancer that can quickly adapt against chemotherapy. It will commence in August.
It will be led by Associate Professor Christine Chaffer and Dr Beatriz San Juan from the Garvan Institute of Medical Research, and Senior Staff Specialist in medical oncology Dr Rachel Dear of St Vincent’s Hospital Sydney. The trial will be conducted at The Kinghorn Cancer Centre in Darlinghurst.
A surgically implanted electronic device could restore blinking to those who can’t
Researchers from the University of Sydney have created a device that can restore the ability to blink in people with facial paralysis, solving a medical as well as a social problem.
The Bionic Lid Implant for Natural Closure (BLINC) is an implant which actively closes the eyelid. The smart electronics detect when the individual will blink on their healthy side, triggering the device to blink for the paralysed eye.
The Astronomical Society of Australia (ASA) will honour the five at its Annual Scientific Meeting in Hobart 27 June – 1 July.
“Australian astronomers are among the best in the world, and the breadth of these prestigious awards shows why we lead the world in so many areas. It is a pleasure to recognise these examples of individual brilliance, as well as teamwork, and technical innovation,” says ASA President Professor John Lattanzio.
Merck, a leading science and technology company, is proud to support DeadlyScience’s new program DeadlyLab to create STEM learning kits for students in remote areas. The kits will explore chemistry, physics, and biology with experiments based in Indigenous science.
DeadlyScience was founded in 2019 by proud Kamilaroi man Corey Tutt OAM, and has delivered more than 20,000 books, 500 telescopes and countless other learning tools to students in remote communities.
Now, Merck and DeadlyScience are partnering with Indigenous communities, Elders, and Indigenous subject-matter experts to create experiments, complete with worksheets and video tutorials, that can be used in school classrooms or at home.
“We work with hundreds of remote schools, who collectively have more than 28,000 students. Over 75% are Indigenous.
“We want to get them engaged with science, help them learn with play and hands-on experience, and show them Indigenous scientists. You can’t be what you can’t see,” says Corey.
