Hypersonic travel

Brussels to Sydney in less than three hours

A passenger jet could one day fly halfway around the world in just a few hours. That’s the goal of the HEXAFLY project (High-speed Experimental FLY): going beyond the supersonic realm pioneered by the now-defunct Concorde to reach hypersonic speeds more than five times as fast as sound.

Led by the European Space Agency, the project has now brought on international collaborators to prepare for an early stage test flight planned for 2020.

The shape of a perfect storm: saving lives by predicting firestorms

Correction: an earlier version stated the tool is being formally trialed by the NSW Rural Fire Service. It is currently in use, but formal trials ended in 2016.

Firestorms are a nightmare for emergency services and anyone in their path. They occur when a bushfire meets a ‘perfect storm’ of environmental conditions and creates a thunderstorm.

Dr Rachel Badlan and Associate Professor Jason Sharples are part of a team of experts from UNSW Canberra and ACT Emergency Services that has found the shape of a fire is an important factor in whether it will turn into a firestorm.

Fires that form expansive areas of active flame, rather than spreading as a relatively thin fire-front, are more likely to produce higher smoke plumes and turn into firestorms, the researchers found.

This finding is being used to underpin further development of a predictive model for firestorms. The model was trialed in the 2015 and 2016 fire seasons by the ACT Emergency Services Agency and the NSW Rural Fire Service, and now forms part of the national dialogue around extreme bushfire development.

Slipped discs: robot shows it’s not all bending and twisting

Some slipped disc injuries might be caused by movements other than the commonly blamed bending and twisting, according to new research by South Australian engineers.

It’s a finding that will lead to a better understanding of the motions that put people at greatest risk of a slipped disc and help develop more robust guidelines for safe lifting.

Kid-friendly chocolate formula helps the medicine go down

Researchers from The University of Western Australia have developed a winning medicine formula that makes bad-tasting medicine taste nice, making it easier to treat sick children.

The UWA study published by the journal Anaesthesia tested 150 children and found that the majority of children who were given the new chocolate-tasting medicine would take it again, unlike the standard treatment, while they still experienced the same beneficial effects.

UWA Clinical Senior Lecturer Dr Sam Salman said the poor taste of many medicines, such as Midazolam, a sedative used prior to surgery, presented a real difficulty in effectively treating children.

Keeping ahead of a child killer: stopping gastro from birth

UPDATE 22 February 2018:  

A vaccine has been developed against rotavirus, which is the common cause  of severe diarrhoea and a killer of approximately 215,000 children under five globally each year.

The oral vaccine was given in three single doses, the first within five days of birth. After three doses of RV3-BB administered from birth:

  • 94 per cent of infants were protected in their first year of life against severe rotavirus gastroenteritis
  • 75 per cent of infants were protected to 18 months of age.

The success of the RV3-BB vaccine is the culmination of more than four decades of work, which started with the Murdoch Children’s Research Institute’s Professor Ruth Bishop and the discovery of rotavirus in 1973.

The trial was funded by the National Health and Medical Research Council (NHMRC), Bill & Melinda Gates Foundation and PT BioFarma.

Read the full media release on the MCRI website.

——

A new rotavirus vaccine should soon be available thanks to a collaboration between PT Bio Farma and researchers in Melbourne and Yogyakarta. The new ‘RV3’ vaccine is aimed at protecting babies from birth, improving protection and simplifying delivery.

The current vaccine, available in Australia and only on the private market in Indonesia, can only be administered from six weeks of age.

Fresh Science

Fresh Science helps Australian early-career researchers find their story and their voice.

Over the past 20 years Fresh Science has trained and empowered more than 500 future leaders in science to engage with the community, media, government and industry.

In 2016, we chose 60 researchers around the country, trained them, and gave them the chance to present their science in pubs, school talks and to the media. Here are a few of their stories.

From the ocean floor to batteries—partners in energy

Heading into deep water

Perth researchers help Chevron keep oil and gas flowing smoothly

Out in the Gulf of Mexico Chevron are operating a $7.5 billion platform that’s recovering oil and gas from two-kilometre-deep ocean.

It’s the largest and deepest operation in the Gulf, with over 146km of pipeline bringing oil and gas to refineries.

But pipelines operating at extreme depths in cold water and crushing pressure are prone to blockage. University of Western Australia researchers are helping Chevron keep oil and gas flowing through deep-water pipes.

Reinventing the laser

High-power lasers have many potential applications: from medical imaging to manufacturing, shooting down drones or space junk, or powering deep space probes. But current laser technologies overheat at high power.

Associate Professor Rich Mildren and his team have developed a technique to make diamond lasers that, in theory, have extraordinary power range. Five years ago, their lasers were just a few watts in power. Now they’ve reached 400 watts, close to the limit for comparable conventional lasers.

Healthier trucks and clean air underground—partners in mining technologies

American mines are safer and more efficient thanks to Australian technologies

‘Blood tests’ for big machines

Mining companies across America are increasing the reliability of their trucks, diggers, and other big machines, and saving hundreds of millions of dollars in the process.

They’re giving these big machines regular health tests and comparing the results with a global database for that machine.

The result? They’re fixing machines before they break. This preventative health system was developed by an Australian company, Dingo, which now has 40 people working at its bases in Denver, Brisbane, and Calgary.

Are memories stored in DNA?

The idea that long-term memory might be stored in our brain’s DNA is being tested by Professor Geoff Faulkner, using brains affected by Alzheimer’s.

Geoff has already shown that the DNA in our brains is different to the DNA in the rest of our bodies and that it changes as we learn. He’s proposing that these changes are associated with how we store our long-term memories.

More recently, he’s linked these differences to the function of genes in the hippocampus, the part of the brain that controls memory and spatial navigation, and has been implicated in memory loss with ageing, schizophrenia and Alzheimer’s disease. Continue reading Are memories stored in DNA?
