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.
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.
Scarring and major lacerations due to vessel collisions
becoming more common, study finds.
Almost one-fifth of the whale sharks (Rhincodon typus) in Western Australia’s Ningaloo
Reef Marine Park show major scarring or fin amputations, with the number of
injured animals increasing in recent years, new research reveals.
Distinctive scar patterns strongly suggest many of the injuries are caused by boat collisions, says whale shark scientist Emily Lester from the Australian Institute of Marine Science (AIMS).
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.
