When parallel worlds collide … quantum mechanics is born

Parallel universes – worlds where the dinosaur-killing asteroid never hit, or where Australia was colonised by the Portuguese – are a staple of science fiction. But are they real? In a radical paper published…

Explainer: what is a solar eclipse?

A couple of weeks ago, we were treated to a total lunar eclipse – and on Thursday afternoon, North America will see a partial solar eclipse. Each month, at the time of new moon, the sun and moon are together…

Under the volcano: predicting eruptions and coping with ash rain

Living alongside active volcanoes in places like Japan, the Philippines and especially Indonesia can be uncomfortable. Around half a billion people in the world live near high-risk volcanic eruption areas…

Australian rock art is threatened by a lack of conservation

Australian rock art is under threat from both natural and cultural forces impacting on sites. But what saddens me the most is that there is so much government lethargy in Australia when it comes to documenting…

Want to win? Let music give you the edge

Let’s hope the Wallabies are inspired by a rousing rendition of the national anthem as they prepare to face their old enemy the All Black’s at tomorrow’s Bledisloe Cup match. The Kiwis invariably come…

Is Australia’s claim to Antarctica at risk?

While Australia’s commitment to a 20-year plan for Antarctica has been welcomed by some it has also raised concerns over the nation’s ability to fulfil a credible research role in the south polar region…

Quantum computing poised for new silicon revolution

A dramatic increase in the amount of time data can be stored on a single atom means silicon could once again play a vital role in the development of super-fast computers. The silicon chip revolutionised…

Dark matter and the Milky Way: more little than large

While invisible, dark matter completely dominates our Milky Way. But recent measurements of just how much dark matter there is have revealed a bit of a mystery. In a paper published today in the Astrophysical…
