New bendable cement-free concrete can potentially make safer, long-lasting and greener infrastructure.

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 building collapses.

Ghostly traces of massive ancient river revealed

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.

Brain temperature can now be measured using light

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.

Tea trees crave water during hot and dry summer days

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.

New clues for allergy prevention by breast milk

Written by Akila Rekima and the University of Western Australia. For the full UWA press release, click here.

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.

Goannas return to mine site

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.

One step closer to understanding cancer-fighting immune cells

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.

Whooping cough is fighting back.

Researchers discover how whooping cough is evolving paving the way to a new vaccine.

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.

Is that plant healthy?

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 plantations.

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.

Protecting Tiwi wildlife is a hollow argument

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).
