Using a face mask, Adelaide researchers have a new way to detect a major hidden equine health issue.

Up to 80 percent of horses – including racehorses and showjumpers – suffer from a form of asthma that affects their performance and wellbeing.

“Currently the methods that are available to diagnose the mild to moderate form of horse asthma are invasive,” says Surita.

Have you seen a sawfish?

From Sydney to Cairns to Darwin to Perth, we want to hear about your sightings – a live fish, a saw on the wall of your local pub, or a photo from your family album.

Forty years ago, sawfish were regularly seen off Sydney and the east coast, and Perth and up the west coast. Today they’re rarely seen outside of the Gulf of Carpentaria, NT and the Kimberley.
