Beetroot juice and exercise are being investigated as a treatment for cardiovascular problems. And understanding the workings of the combination could lead to other, more sophisticated therapies.
That’s the hope of Professor Jason Allen and his PhD student Mary Woessner from the Institute of Sport, Exercise and Active Living (ISEAL) at Victoria University in western Melbourne. Continue reading The right juice for your heart
Australia and the USA have long been close partners in research and innovation. And Australian inventions have had a huge impact on American lives.
The bionic ear is introducing children to the hearing world. Vaccines are protecting against cancer. Chewing gum is repairing tooth decay. And Australian astronomy helped make Wi-Fi fast and reliable.
Here we feature some of the latest collaborations and achievements.
Some 30 million Americans use contact lenses. Today they can wear a single pair for up to 30 consecutive days and nights, safely and comfortably thanks to the work of CIBA Vision and CSIRO, Australia’s national science agency.
Contact lenses were once rigid and had to be taken out every night. In 1991, a team of researchers from CSIRO, the University of New South Wales, and the Vision Cooperative Research Centre joined forces with CIBA Vision in the US, and Novartis in Switzerland, to create a better contact lens.

The science underpinning modern farming has enabled our farmers to become more efficient, and more profitable.
Take grain for example. American farmers grow over 440 million tonnes of grain each year. Australia produces about 40 million tonnes. Together that’s about one-sixth of global grain production. Good science has contributed to a tripling in grain production over the past half century.
Both nations export to the world. But whenever we store and transport grain the bugs bite. The latest collaborative research between our two nations is changing that.

Today, your phone is also being protected from cyberattacks by Australian software that works within the kernel of the phone’s operating system to protect it from hacking and software faults. The kernel is the most fundamental part of an operating system. It acts between the hardware and the applications.
Now Australian researchers are working to secure America’s growing fleets of autonomous machines, with ‘microkernel’ software known as seL4.
The new software is built on the work of researchers at the University of New South Wales and National ICT Australia (now CSIRO’s Data61 Group).

Almost everyone has had their blood pressure measured with an inflatable cuff around the arm. But as useful as this is, it can differ from the reading at the heart itself.
Twenty years ago Sydney scientists found a way to get that extra information. They created a model that gives the pressure at the main artery of the heart, using the wrist’s pressure pulse (the shape of the ‘waves’ that both travel along arteries when the heart pumps blood, and travel back to the heart as it fills with blood).
The model wasn’t applicable to children, since their limbs are still growing – so now they’re adapting it to fit.
You’re in hospital: should you stay? Should you leave? What’s your risk of dying?
By mining electronic health records, researchers at Macquarie University believe they can help improve decision making by health professionals.
Dr Blanca Gallego Luxan is investigating using hospital information and state health and death registries to fill gaps in patient care – whether due to discontinuity of care, lack of information on a condition, or simply the limits of what humans can predict.
Lithium batteries have transformed power storage—from smartphones to electric cars and submarines. But like every battery their chemical composition changes through every charge cycle.
Lithium ions sitting in layers of graphite move between electrodes and change the oxidation state of, magnesium oxide, for example. The chemical rearrangements cause the graphite and oxide layers to physically expand and contract by up to 15 per cent at every cycle, cracking and detaching from the electrodes.
Cool thinking by an Australian defence scientist while a bushfire bore down on his family home provided first responders with clearer satellite images of the blaze, and likely prevented further devastation.
The Sampson Flat bushfires in South Australia claimed the lives of around 900 animals, destroying 27 houses along with other property in January 2015.
Chris Ekins evacuated his family, but while preparing to protect their home he heard on local ABC radio that aircraft were having difficulty seeing through the smoke.
Scientists in Australia and California have worked out how to unboil an egg. It may sound like an odd discovery, but it’s changed the way scientists think about manipulating proteins, an industry worth AU$160 billion per year.
Flinders University Professor Colin Raston and his team have developed Vortex Fluid Technology – using mechanical energy, or spinning, to reverse the effects of thermal energy, or boiling.
