After 90 years, scientists reveal the structure of benzene.
One of the fundamental
mysteries of chemistry has been solved by Australian scientists – and the
result may have implications for future designs of solar cells, organic
light-emitting diodes and other next gen technologies.
Ever since the 1930s debate has raged inside chemistry
circles concerning the fundamental structure of benzene. It is a debate that in
recent years has taken on added urgency, because benzene – which comprises six
carbon atoms matched with six hydrogen atoms – is the smallest molecule that
can be used in the production of opto-electronic materials, which are
revolutionising renewable energy and telecommunications tech.
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
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.
Their preclinical data and human birth cohorts analysis strongly suggest that egg-derived allergen protect against egg allergy. But they’ve also found that other allergens in breast milk such as house dust mite derived allergens may interfere with protection from allergies.
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 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.
