Inventing the ultimate suspension system

To hear tiny vibrations from half a galaxy away, first you need to filter out the Earth’s constant rumbling.

At gravitational wave observatories such as the European Advanced Virgo in Italy, scientists try to detect ripples in spacetime caused by colliding black holes and other stellar cataclysms.

Making wine in a warming world

South Australian winemakers are looking to Europe as the climate—and what drinkers want—is changing.

Grapes don’t ripen the way they used to. As temperatures climb, they are getting sweeter faster.

Winemakers find that by the time the crop achieves the right colour or level of tannins, the grapes contain more sugar. More sugar means heavier, more alcoholic wine. At the same time, drinkers are preferring lighter wines Continue reading Making wine in a warming world

Looking for dark matter in a gold mine

Deep underground in rural Victoria, Matteo Volpi is searching for evidence of the cosmic glue that holds the Universe together: dark matter.

Matteo is taking the initial measurements for the study at Stawell Gold Mine where an international team is set to construct a $3.5 million laboratory more than a kilometre underground.

Understanding dark matter is regarded as one of the most important questions of modern particle physics.

“If we nail it, it’s a Nobel Prize– winning experiment,” says the project leader Elisabetta Barberio, a University of Melbourne physicist and chief investigator of the Australian Research Council Centre of Excellence for Particle Physics at the Terascale (CoEPP).
