How Australia played the world’s first music on a computer

It might not sound like the best music in the world, but Australia was the first by a matter of months at playing a tune on a computer.

The need for speed: there’s still time to fix Australia’s NBN

It is not too late to change the current direction of Australia’s NBN from one that just meets today’s demands, to one that we need for the future.

Collecting data to help protect Australia’s waters from toxic algal blooms

They give us part of the air we breathe but microscopic phytoplankton can also be toxic. They are also on the move thanks to climate change so a new Australian database hopes to monitor any changes.

Why so many Australian species are yet to be named

At least 100,000 insects are among the many Australian species still to be formally identified. That’s a problem for any biosecurity experts who need to be able to spot potentially invasive bugs.
An anaconda peers above and below the water. Did snakes evolve on land or underwater? Michael Lee (Flinders University & South Australian Museum)

Did snakes evolve from ancient sea serpents?

One of the enduring controversies in evolution is why snakes evolved their long, limbless bodies. A new study suggests snakes may have lost their legs at sea, before crawling ashore.

Second detection heralds the era of gravitational wave astronomy

The observation of gravitational waves from a second black hole merger implies there are many more black holes in the universe than scientists had previously anticipated.

Explainer: How to find an exoplanet (part 2)

A look at some of the more obscure methods astronomers use to detect planets around other stars, in the second of a two-part series on finding world’s elsewhere in the universe.
Jamie Milpurr translates archived stories told by his grandfather Frank Ambidjambidj with help from his grandmother Margaret Marlingarr. The stories were told in Kun-barlang, a language spoken on Goulburn Island with 20 speakers remaining. Steven Bird

Computing gives us tools to preserve disappearing languages

A clever proces similar to Google’s image search is helping to preserve some of the world’s 7,000 languages that are at risk of disappearing.

How citizen scientists discovered a giant cluster of galaxies

The find by citizen scientists of at least 40 galaxies in a cluster more than a billion light years away is the astronomical equivalent of finding a needle in a haystack.

How do Labor and the Coalition differ on NBN policy?

Now the ALP has released its much-anticipated National Broadband Network policy, it gives voters a chance to see how the Coalition and the Opposition’s plans compare.

Computers may be evolving but are they intelligent?

Computing has been getting much smarter since the idea of artificial intelligent was first thought of 60 years ago. But are computers intelligent?

Driverless cars need to hit the road come rain, wind or shine

Driverless cars are the technology of the future, but unless they learn how to drive in rain and snow, they will be a technology that lets us down when we need it the most.
