helps rangers protect national parks, despite tight budgets.
Mathematics can help reduce poaching and illegal logging in national parks, researchers have found.
team of applied mathematicians including Macquarie University’s David Arnold
has developed an algorithm that predicts which areas inside park boundaries
offer the greatest possibilities for criminals – and how rangers can most
efficiently combat them.
close in on an objective measure for physical distress.
A new microscope-based method for detecting a particular molecule in the spinal cord could help lead to an accurate and independent universal pain scale, research from Australia’s Macquarie University suggests.
An accurate way of
measuring pain is of critical importance because at present degrees of
discomfort are generally assessed by asking a patient to estimate pain on a
one-to-10 scale. The situation is even more acute in the treatment of babies,
the very old and animals, where speech is absent.
Cognition is influenced by siblings, researchers find.
Autistic children with autistic siblings have better
cognition than those who are the only family member with the condition, researchers
Importantly, the outcome does not depend on birth order.
Although previous studies have identified that having
autistic siblings leads to better cognition for individual children with the
condition, it was assumed that the order in which the children were born was a
Filtering out social bots can help critical response teams see what’s
happening in real time
Researchers have created an algorithm that distinguishes
between misinformation and genuine conversations on Twitter, by detecting
messages churned out by social bots.
Dr Mehwish Nasim and colleagues at the School of Mathematical
Sciences at the University of Adelaide say the algorithm will make it easier
for emergency services to detect major events such as civil unrest, natural
disasters, and influenza epidemics in real time.
“When something really big is going on, people tweet a
huge amount of useful information,” says Mehwish.
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
Researchers from The University of Western Australia have developed a winning medicine formula that makes bad-tasting medicine taste nice, making it easier to treat sick children.
The UWA study published by the journal Anaesthesia tested 150 children and found that the majority of children who were given the new chocolate-tasting medicine would take it again, unlike the standard treatment, while they still experienced the same beneficial effects.
UWA Clinical Senior Lecturer Dr Sam Salman said the poor taste of many medicines, such as Midazolam, a sedative used prior to surgery, presented a real difficulty in effectively treating children.
A patented treatment could restore eyesight for millions of sufferers of corneal disease.
The University of Melbourne-led team of researchers have grown corneal cells on a layer of film that can be implanted in the eye to help the cornea heal itself. They have successfully restored vision in animal trials and are aiming to move to human trials in 2017.
