The remains of volcanoes from billions of years ago are helping scientists identify both bygone continental boundaries and new places to find mineral resources in Australia.

How to stop people entering floodwater
People continue to enter floodwater in vehicles and on foot, despite many knowing the risks.
Researchers from the Bushfire Natural Hazards CRC and Risk Frontiers, Macquarie University, analysed the who, when and why of flood fatalities, so they could target information to high-risk groups and hopefully prevent further deaths. Continue reading How to stop people entering floodwater
Saving lives with better processes
How can a doctor in a small practice with only one or two GPs learn from the mistakes of doctors across the country?
In any small practice, there’s a risk that an error can be interpreted as a one-off event, as there is limited awareness that the same incident could be occurring in other practices.
More accurate readings of the heart
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.
Changing the minds of dementia patients
“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.
What happens next?
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.
Hoarding disorder: why is it hard to part with stuff?
“I’m fascinated by why people love objects so much,” says Dr Melissa Norberg, Director of the Behavioural Science Laboratory at Macquarie University.
“What is it about the items (or the person) that makes objects so appealing?”
While we’re all guilty of holding on to a few sentimental things, Melissa’s interest is in studying those who meet the criteria for hoarding disorder.
With Associate Professor Jessica Grisham at the University of New South Wales, Melissa has been investigating how mood affects peoples’ ability to throw things out.

Expanding treatments for the ‘Australian’ cancer
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.

Widening the net on Motor Neurone Disease
Recent advances pinpointing genes involved in the inherited form of Motor Neurone Disease (MND) are now being used to hunt for the culprits of ‘sporadic’ cases.

Sporadic MND is the most common form (around 90 per cent), and unlike the ‘familial,’ disease, it appears in patients without a family history.
Helping patients cope with cancer
Pairing psychology with cancer treatment has a profound impact on the wellbeing of patients, Associate Professor Maria Kangas and her team at the Centre for Emotional Health have found.
In a recent clinical trial, head and neck cancer patients were offered weekly cognitive behavioural therapy (CBT) sessions concurrent to their radiation therapy appointments.
After just seven sessions, patients reported a significant decline in cancer-related anxiety and/or depression. And after a year, 67 per cent were no longer experiencing any anxiety or depression and were doing better than the control group who had received regular counselling, but not CBT.
