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.
Decades of meteorological data are telling the story of Australia’s birds.
Weather radar can be used to better manage bird populations
and potentially save them from extinction, a researcher at Charles Darwin
University in the Northern Territory has found.
Rebecca Rogers has been using weather radar to track the
movement patterns of Magpie geese (Anseranas semipalmata) to demonstrate
how the data generated can improve the management of Australia’s waterbirds.
The radars routinely pick up birds in flight, but while the
information is a nuisance for meteorologists, it is a boon to ecologists.
We all rely on GPS to tell us where we are and where we’re
going. The US government’s global network of 30+ satellites guides planes,
ships, cars, tractors and much more. The latest GPS systems can provide mm- to
cm-accuracy using advanced equipment and technique.
But GPS isn’t the only game in town. There are other
global systems, and regional systems that we can tap into.
Curtin University researchers have explored the potential
of regional navigation satellite systems (RNSSs) for Western Australian users.
Two such systems are the QZSS operated by Japan and the IRNSS operated by
Australia’s National Bowel Cancer Screening Program is still the best way to reduce incidence and mortality for bowel cancer, according to research published in the journal Cancer Epidemiology, Biomarkers and Prevention, by University of Western Australia researcher Dayna Cenin.
She predicts that personal genomics will enable more
targeted screening over the coming decades, but not yet.
Sky survey provides clues to how they change over time.
The direction in which a galaxy spins depends on its mass, researchers have found.
A team of astrophysicists analysed 1418 galaxies and found that small ones are likely to spin on a different axis to large ones. The rotation was measured in relation to each galaxy’s closest “cosmic filament” – the largest structures in the universe.
Filaments are massive thread-like formations, comprising huge amounts of matter – including galaxies, gas and, modelling implies, dark matter. They can be 500 million light years long but just 20 million light years wide. At their largest scale, the filaments divide the universe into a vast gravitationally linked lattice interspersed with enormous dark matter voids.
A novel citizen science project in New Caledonia finds an ‘astonishing’ number of venomous reptiles in a popular swimming spot.
A group of snorkelling
grandmothers is helping scientists better understand marine ecology by
photographing venomous sea snakes in waters off the city of Noumea, New Caledonia.
Two years ago the seven women, all in their 60s and 70s, who call
themselves “the fantastic grandmothers”, offered to help scientists Dr Claire
Goiran from the University of New Caledonia and Professor Rick Shine from
Australia’s Macquarie University in their quest to document the sea snake
population in a popular swimming spot known as Baie des citrons.
Apex marine predators choose who they hang with, researchers reveal.
White sharks form
communities, researchers have revealed.
solitary predators, white sharks (Carcharodon
carcharias) gather in large numbers at certain times of year in
order to feast on baby seals.
These groupings, scientists had assumed, were essentially random – the result of individual sharks all happening to turn up in the same area, attracted by abundant food.
a group of researchers including behavioural ecologist Stephan Leu from
Macquarie University in New South Wales, Australia, have used photo-identification
and network analysis to show that many of the apex predators hang out in groups
which persist for years.
Researchers find evidence of a cataclysmic flare that punched so far out of the Galaxy its impact was felt 200,000 light years away.
titanic, expanding beam of energy sprang from close to the supermassive black
hole in the centre of the Milky Way just 3.5 million years ago, sending a
cone-shaped burst of radiation through both poles of the Galaxy and out into
the finding arising from research conducted by a team of scientists led by
Professor Joss Bland-Hawthorn from Australia’s ARC Centre of Excellence for All
Sky Astrophysics in 3 Dimensions (ASTRO 3D) and soon to be published in The
