How deep is your sleep?

Reading brain activity for better anaesthesia

More than 40 million people have major surgery in China each year. For every one of them the nature of consciousness is a very practical concern. Too low a dose of anaesthetic could see you wake up during the operation. Too high a dose could have long term health consequences.

Currently, the best monitoring devices can only monitor a suite of secondary indicators of consciousness. A Guangdong company has partnered with the University of Southern Queensland (USQ) with the aim of making anaesthesia easier and safer. They’re creating an intelligent device to directly measure the depth of unconsciousness and adjust the anaesthetic dose in real time.

Seeing medical devices from concept to commercialisation

It’s difficult to get medical devices out of academia and industry and into end-users’ hands. But a South Australian researcher developed a way to do it—and the program is now set to expand nationally, thanks to funding from the Medical Technologies and Pharmaceuticals Industry Growth Centre.

Devices the program has supported include the U-stand Frame—which helps hospital patients or the elderly stand from a bed with minimal assistance—and a device placed in urinals that gives instant feedback on hydration, to address the impact of heat stress on worker safety.

The sweet side of sulphur: cheap mercury clean-up

A cheap and simple material, using sulphur from petroleum industry waste and plant oils from the food industry, is being tested to clean up mercury pollution from soil and water.

The rubbery material will undergo field tests in 2017 in Australian mining and sugarcane sites, the latter of which use fungicides that contain mercury.  The work is supported by funding from the National Environmental Science Programme’s emerging priorities funding.

“Our technology is about as simple as it can get: mix sulphur with plant oils and heat, then add the resulting material into the contaminated area,” says lead researcher Dr Justin Chalker, of Flinders University. Continue reading The sweet side of sulphur: cheap mercury clean-up
