A new type of concrete that is
made out of waste materials and can bend under load has been developed by
researchers from Swinburne University of Technology in Melbourne, Australia.
This material, which
incorporates industrial waste products such as fly ash produced by coal-fired
power stations, is especially suited for construction in earthquake zones – in
which the brittle nature of conventional concrete often leads to disastrous
Using zircon crystals, researchers have discovered the route of a massive ancient river that could help find new reservoirs of fossil fuels and suggest how modern rivers might change over time.
More than two thirds of the worlds’ major cities are located in coastal deltas. How they change over time can impact communities that live around them.
Nanotech technique could revolutionise neurological treatments.
Light could replace invasive techniques to measure brain temperature– eliminating the need to place a thermometer in the brain when treating a range of neurological disorders.
Researchers from Victoria’ Swinburne University have teamed up with Universidad Autónoma de Madrid in Spain and Stanford University in the US to develop a technique for measuring sub-degree brain temperature changes using near-infrared light.
The iconic Australian tea tree (Melaleuca decora) is more vulnerable than native eucalypt species to extreme temperature and moisture stress, Western Sydney University researcher Anne Griebel has discovered.
To make the finding, Anne and colleagues fitted instruments that measure the exchange of carbon, water and heat at 10 times a second to an extendable mast on a trailer deployed in a critically endangered woodland in Western Sydney.

A research team at UWA is investigating the complex
interactions of breast milk with allergens and baby’s gut immune system.
They’ve found that food-derived but also airborne allergens are present in breast milk. Some do give protection and reduce allergies later in life.
Animals play critical roles in ecosystems, but they are broadly overlooked in assessments of mine site restoration success says Sophie Cross, an ecologist at Curtin University.
She tracked Australia’s largest lizard species, the perentie, using VHF radio and GPS tracking, and walked hundreds of kilometres through unmined and restoration bushland on a mine site in the mid-west region of Western Australia for her study published in the Australian Journal of Zoology.
Researchers discover that protective immune cells are not created equally
Personalised treatment of cancers has moved one step closer, thanks to University of Melbourne researcher Dr Susan Christo.
Increasingly, cancers are being treated
using an approach called immunotherapy – which uses a patient’s own immune
cells to fight the disease.
However, challenges arise in so-called
“solid cancers”, such as melanoma, where access may be limited so the
cancer-fighting immune cells cannot penetrate the tumour site.
Researchers discover how whooping cough is evolving paving the way to a new
Whooping cough strains are adapting to better infect
humans, a team of Sydney researchers has found.
The scientists, led by microbiologist Dr Laurence Luu of the University
of New South Wales, may have solved the mystery of why, despite
widespread vaccinations, the respiratory disease has been resurgent in
Australia across the past decade. There have been more than 200,000 cases
recorded during the period.
We can’t easily monitor the health
of plants, by the time we see that they’re sick it’s usually too late to save
that. That’s an issue for your house plants, a field of wheat, orchards and
Karina Khambatta has developed a
way to use the waxy surface of leaves to monitor their health.
Currently the technique uses
infrared spectroscopy to study changes seen throughout leaf senescence. Karina
has had the opportunity to utilise the infrared microscopy lab located at the
Australian Synchrotron to help correlate her infrared studies undertaken at
Curtin University, but Karina believes it can be turned into a handheld device
that could be used on-farm, like reading a barcode.
Climbing trees reveals a housing shortage for tree-rats and other endangered animals.
Estimates of tree hollows – which form the houses of
several endangered species in northern Australia – are much too high,
researchers at Charles Darwin University in the Northern Territory have found.
And the discovery could be bad news for several of
Australia’s most vulnerable species, including the Black-Footed Tree-Rat (Mesembriomys gouldii) and Brush Tailed Rabbit-Rat (Conilurus penicillatus).
