The shape of a perfect storm: saving lives by predicting firestorms

Firestorms are a nightmare for emergency services and anyone in their path. They occur when a bushfire meets a ‘perfect storm’ of environmental conditions and creates a thunderstorm.

Dr Rachel Badlan and Associate Professor Jason Sharples are part of a team of experts from UNSW Canberra and ACT Emergency Services that has found the shape of a fire is an important factor in whether it will turn into a firestorm.

Fires that form expansive areas of active flame, rather than spreading as a relatively thin fire-front, are more likely to produce higher smoke plumes and turn into firestorms, the researchers found.

This finding is being used to underpin further development of a predictive model for firestorms. The model was trialed in the 2015 and 2016 fire seasons by the ACT Emergency Services Agency and the NSW Rural Fire Service, and now forms part of the national dialogue around extreme bushfire development.

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.

Overcoming knee pain with the help of a digital twin

Researchers have developed computer simulations of joint and muscle movements that can teach us how to exercise smarter and prevent knee pain and further damage.

One in five Australians over the age of 45 suffer from painful and debilitating osteoarthritis, with the knee being the most commonly affected joint.  

Dr Claudio Pizzolato from Griffith University is making computer avatars or ‘digital twins’ of individual patients to see how their muscles and joints work. [continue reading…]

Nominations for Fresh Science now open

Do you know any early-career researchers who have peer-reviewed results, a discovery, or an invention that has received little or no media attention?

Please nominate them for Fresh Science, our national competition that helps early-career researchers find, and then share, their stories of discovery. Scientists get a day of media training and the chance to share their work with the media, general public and school students.

Fresh Science is looking for:

  • early-career researchers (from honours students to no more than five years post-PhD)
  • a peer-reviewed discovery that has had little or no media coverage
  • some ability to present ideas in everyday English.

Fresh Science 2018 will run in Queensland, South Australia, Western Australia, Victoria and NSW. We’ll also run it in other states and territories where we can secure local support.

I’d appreciate it if you could circulate this to early-career researchers in your organisation.

If you’d like to share our flyer calling for nominations, you can download it as a PDF or a jpeg or share the call on social media using #FreshSci

Smart socks help physiotherapists treat patients remotely

‘Smart socks’ are helping physiotherapists better assess and treat patients during video consultations, by providing information on weight distribution and range of movement during exercises like steps, squats or jumps.

The wearable technology, developed by PhD candidate Deepti Aggarwal at The University of Melbourne, was trialled with three patients and a physiotherapist at the Royal Children’s Hospital, from February to June 2017.

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 next year.

Berkay Photo - Fresh Science ProfileVictor Fortmann’s vision in one eye failed following a condition called bullous keratopathy. Two donated cornea transplants restored his sight for a period, but he now needs a third to restore his vision in that eye.

Over 2000 corneal transplants are conducted in Australia each year. But globally there’s a shortage of donated corneas, and the resulting loss in vision affects about 10 million people worldwide.

“We believe that our new treatment performs better than a donated cornea, and we hope to eventually use the patient’s own cells, reducing the risk of rejection,” says Berkay Ozcelik who developed the film working at the University of Melbourne.

“Further trials are required but we hope to see the treatment trialled in patients next year,” he says.

Blood reveals Great Barrier Reef sharks as homebodies

Small Australian sharks have been exposed as bigger homebodies than previously thought, in a study that took an existing chemical tracking technique and made it work for Great Barrier Reef sharks.

The study found that the travel history of the Australian sharpnose shark was written in their blood—with chemical ‘fin-prints’ showing they tended to stay within smaller areas than previously believed.

“Small-bodied sharks that are both predator and prey, such as the Australian sharpnose, may be particularly important links between food webs,” says lead researcher Dr Sam Munroe, who studied the sharks while at James Cook University in Townsville.

“Information on their movements can improve our understanding of how the ecosystems function, while also helping us predict species most at risk from the impacts of a changing environment.”

Brain training to give tendon pain the boot

Re-training the brain with painless exercises may be the key to stopping recurring tendon pain, according to Melbourne researchers.

AFL, basketball and netball players are the major sufferers, with tendon pain in the knee debilitating and long-lasting. The injury can sideline a player or cause them to give up the sport entirely.

“More than 50 per cent of people who stop sport because of tendon pain still suffer from that pain 15 years later,” says Dr Ebonie Rio of the Monash University Tendon Research group.

“Our simple exercise is revolutionising how we treat tendinopathy.”

Not to be sniffed at! Nose spray offers pain relief in childbirth

Pain relief during childbirth may soon be delivered via a self-administered nasal spray, thanks to research from University of South Australia midwifery researcher, Dr Julie Fleet.

Well known for its use in delivering pain relief to children and in managing pain in patients being transferred by ambulance, the nasal spray analgesic drug, fentanyl, has now been shown to be effective in relieving labour pain.

In fact Julie and her colleagues at Flinders University and the University of Adelaide have found that fentanyl nose spray is just as effective as pethidine injections, which are commonly used, but fentanyl has fewer side effects for both mother and baby.
