Adelaide researchers find how a bacteria digests a sugar can be key to new treatments

Vikrant Minhas, University of Adelaide

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.

Researchers use sound to deliver drugs

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.

Mapping our galaxy’s magnetic field

Dr Charlotte Sobey, CSIRO and Curtin University

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.

Questions and humour the keys to social media success

Researcher finds linguistic tricks that boost Facebook post engagement

Matteo Farina, University of Adelaide and Flinders University

Some Facebook posts are more successful than others and linguist Matteo Farina has worked out why.

By 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.
