We recently published a report that found that waves in the ocean could supply about ten per cent of Australia's electricity by 2050.
This is equivalent to powering a city the size of Melbourne.
The areas that could benefit from wave energy technology include Perth, the southern coastline and to a lesser extent the east coast of Australia. Tidal technology could supply niche areas such as north east Tasmania and the Kimberley region in Western Australia.
Although wave energy could supply about ten per cent of our energy by 2050, there are many economic, technological, environmental and societal challenges that will determine its place in Australia’s future energy mix.

The GI of rice- the long and short of it
Research analysing 235 types of rice from around the world has found its glycemic index (GI) varies from one type of rice to another with most varieties scoring a low to medium GI.
This finding is good news because it not only means rice can be part of a healthy diet for the average consumer, it also means people with diabetes, or at risk of diabetes, can select the right rice to help maintain a healthy, low GI diet.
GI is a measure of the relative ability of carbohydrates in foods to raise blood sugar levels after eating. When food is measured to have a 'high GI', it means it is easily digested and absorbed by the body, which often results in fluctuations in blood sugar levels that can increase chances of getting diabetes, and make management of Type 2 diabetes difficult.

The carbon sink in the Southern Ocean
The Southern Ocean is an important carbon sink in the world – around 40 per cent of the annual global CO2 emissions absorbed by the world’s oceans enter through this region.
Reporting this week in the journal Nature Geoscience, scientists from British Antarctic Survey and the CSIRO, reveal that rather than carbon being absorbed uniformly into the deep ocean in vast areas, it is drawn down and locked away from the atmosphere by plunging currents a thousand kilometres wide.
Winds, currents and massive whirlpools that carry warm and cold water around the ocean – known as eddies – create localised pathways or funnels for carbon to be stored.

The pain relieving green whistle, used in Australia by emergency services, defence forces and surf lifesaving services, could soon be used in the UK and Europe.
We have signed a technology deal with Medical Developments International (MDI) who manufactures the whistle - officially known as Penthrox.
We will develop a new production process for methoxyflurane, the drug used in Penthrox.
If successful, the project will help reduce the cost of producing Penthrox and facilitate large-scale production to support MDI’s plan to sell it in the UK and Europe.
We are investing $750,000 under the Australian Growth Partnerships (AGP) program into the project.

On The Record
With all the Olympic hype at the moment, it's quite fitting that we've pondered the limitations on human athletic ability.
The crucial question then is, is there a limit? Paul Savage explains in this article that the answer is yes- and it's due to physics.
Tim Davis also ponders physics with this article on wave-particle duality. A great explainer article on quantum mechanics.
Over in the Environment group, Tara Martin has written this article on mammal extinctions. Did you know that nearly half the world's mammalian extinctions have occurred in Australia?
Very quickly- here's a good time-lapse video for you. It features the Australia Telescope Compact Array against the night sky.
The microwave oven was invented by Percy Spencer after he stood near a radar dish & a chocolate bar in his pocket melted.

Welcome to the team
Some of Australia’s most important space, mathematics and digital technologies research will soon be driven by a new leader, with today’s announcement that UK Space Agency chief Dr David Williams has been appointed as CSIRO Group Executive, Information Sciences.
He will take up the Sydney-based role in late November.
Information Sciences, one of five groups in CSIRO, brings together around 1200 staff working in astronomical and space sciences, digital productivity and services, information and communication technologies and mathematical and statistical sciences.
If you're a third year science or engineering student here's your chance to get hands-on experience working on real-world problems... with us.
We offer a range of paid summer vacation scholarships in IM&T, astronomy, ICT and maths & stats.
Get your application in by September 2nd and you could spend the summer growing your brain.
Wander with Wanda
Meet Wanda, our cute and cuddly great white shark who’s heading off on an outback adventure.
Wanda is the star of our Oceans in the Outback road-show that’s bringing an ocean experience to regional Queensland.
During National Science Week the communities of Dalby, Roma, Charleville and Longreach will be able to virtually diving with sharks and fish, learn about pirates and see deep seabeds.
Naturally, Wanda is equipped with a satellite tag so you can follow her adventures here.

August 6th from 1400 AEST
We’re doing our bit to solve the planetary puzzle about life on Mars.
On Monday NASA’s latest rover Curiosity is set to touch down on the red planet, and we will be listening.
Our NASA tracking station outside of Canberra will be the only place on Earth with a direct view of Curiosity’s landing.
Catch the live stream of our Mars Landing festivities here.
To get your head around how much is riding on this landing, watch this video about Curiosity's Seven Minutes of Terror.
For something a little more erudite, our work experience guy Harry wrote a whole bunch of Haikus about Mars. You won't believe us when we say they're great- so check them out yourself.
Or take a step back and read what our own Vanessa Hill has to say about how social media is shaping a new age of space exploration in this blog post.
