While coral reefs around the world are feeling the heat, little-known reefs in Australia’s Kimberley region are prospering, despite living in some of the toughest conditions—and scientists aren’t yet sure why.
The discovery has particular significance this summer with fears of a severe coral bleaching event to hit our northern waters—the result of steadily rising sea temperatures and a strong seasonal El Niño.
WA researchers have found that while coral reefs all around the world are feeling the heat of rising temperatures, some inshore reefs in the Kimberley region’s Bonaparte Archipelago are prospering, despite living in some of the toughest conditions.

A new diagnostic system used to detect cancer cells in small blood samples could next be turned towards filtering a patient’s entire system to remove those dangerous cells – like a dialysis machine for cancer – says an Australian researcher who helped develop the system.
The technique was developed for cancer diagnosis, and is capable of detecting (and removing) a tiny handful of cancer-spreading cells from amongst the billions of healthy cells in a small blood sample.
The revolutionary system, which works to diagnose cancer at a tenth of the cost of competing technologies, is now in clinical trials in the US, UK, Singapore and Australia, and is in the process of being commercialised by Clearbridge BioMedics PteLtd in Singapore.
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.”
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.
Buddhist singing bowls resonate with sound and have inspired a Canberra scientist to create nano-bowls that do the same with light. Using these bowls in solar cells will increase their ability to capture more light and convert it into electricity.
