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.
Professor Thomas Maschmeyer is working to integrate new battery and solar cell technologies into the walls and roofs of new houses, and to transform the somewhat ‘black art’ of catalysis—the process that cracks crude oil into useful fuels, oils and chemicals at every refinery. He has already helped to create over 200 new jobs with four spin-out companies.
“I’m ecstatic about the impact our programs have on kids, and knowing that we’ve changed their lives for the better. But we need to ask ‘what about our retirees?’” says Professor Ron Rapee, ARC Laureate Fellow, and former Director of the Centre for Emotional Health.
Retirees are less likely to suffer from mental health problems but they still develop anxiety and depression – and there’s increasing evidence these conditions are risk factors for dementia.
To make things worse, they’re often left untreated as there’s a perception that it’s normal for older people to suffer depression as they lose their friends, health and independence.
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.
Indonesian and Australian researchers are working together to combat two big killers: pneumonia, and tuberculosis.
Around six million young Indonesians catch pneumonia each year, according to a 2008 study, and it’s the number one killer of children under five. Researchers now think there might be a link to how much time kids are spending out in the sunshine—more specifically, their level of vitamin D.
‘Perfect entanglement’ of two light beams has opened a major step towards highly secure quantum communication systems.
The University of Queensland’s Professor Tim Ralph and his colleagues from Canada and Russia have developed a technique to restore entangled light beams that have been distributed between distant points.
The chances of surviving melanoma are getting better every year. But some cancers still become ‘resistant’ to treatment, and others don’t respond at all.
A collection of over 10,000 blood and 4,900 tissue samples from the biobank at the Melanoma Institute Australia is being used to hunt for clues to predict which patients won’t be responsive to treatment from day one. The researchers, from Macquarie University, are also looking for the basis of developed resistance by the cancer.
