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.

Do you know exactly where you are?

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 India.

Kid-friendly chocolate formula helps the medicine go down

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.

Curing blindness by repairing corneas with invisible films

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.

Perth community can help save Carnaby’s cockatoo

Endangered Carnaby’s cockatoos are adapting to urban life in Perth suburbs. And new research has shown how the community can help save them by creating cockatoo-friendly suburbs.

A world-first study used satellite technology to track the wild cockatoos, which are found only in Australia’s south-west and are often spotted in the suburbs of Perth.

Immune boost for cancer patients with HIV

Cancer is the leading cause of death among people with HIV and yet cancer treatment can be risky as their immune system is already compromised.

Now, a new class of drugs developed at the Kirby Institute at the University of New South Wales is providing hope—demonstrating it is effective in treating the cancer and strengthening the immune response to that cancer.

Fighting dust-mite allergies with fish oil

Kids born to mums who’d taken high doses of fish oil in pregnancy were less likely to have some types of allergies, Adelaide researchers have found.

The trial, run by the South Australian Health and Medical Research Institute (SAHMRI), was the largest in the world to look at the effects of Omega-3—commonly found in fish oil—on allergies in children.
