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.
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.
Adelaide researchers find how a bacteria digests a sugar can be key to new treatments
The severity of a common and often lethal type of bacteria
depends on its ability to process a type of sugar, research from the University
of Adelaide reveals.
Streptococcus pneumoniae causes diseases of the
lungs, blood, ear and brain, killing an estimated one million people every
year. Moreover S. pneumoniae causes
otitis media (infection of the middle ear), which devastates Aboriginal
populations. It also rapidly develops resistance to antibiotics, making it
challenging to treat.
A technique adapted from telecommunications promises more effective cancer treatments.
Drugs can be delivered into individual cells by using
soundwaves, Melbourne researchers have discovered.
Adapting a technique used in the telecommunications
industry for decades, Dr Shwathy Ramesan from RMIT, and colleagues, used the
mechanical force of sound to push against cell walls and deliver drugs more
effectively than treatments currently in use.
The new technique aids in silencing genes responsible for
some diseases, including cancer, by switching them on or off.
Astronomers from CSIRO and
Curtin University have used pulsars to probe the Milky Way’s magnetic field.
Working with colleagues in Europe, Canada, and South Africa, they have
published the most precise catalogue of measurements towards mapping our
Galaxy’s magnetic field in 3-D.
The Milky Way’s magnetic
field is thousands of times weaker than Earth’s, but is of great significance
for tracing the paths of cosmic rays, star formation, and many other
astrophysical processes. However, our knowledge of the Milky Way’s 3-D
structure is limited.
Researcher finds linguistic tricks that boost Facebook post engagement
Some Facebook posts are more successful than others and linguist Matteo Farina has worked out why.
applying a technique known as “Conversation Analysis” to a set of more than
1,200 posts culled from 266 anonymised users, the University of Adelaide and
Flinders University academic has been able to identify specific linguistic
structures common to most Facebook posts that attract a high number of Likes
and written responses.
“This research shows that successful posts project a clear
next action from Friends,” he says.
