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.
