Liking death metal doesn’t make you a violent person

Liking death metal or other aggressive music doesn’t desensitise you to other violent media. Listening to the music of a band called Bloodbath – described as “a Swedish death metal supergroup” – is not, it must be said, an exercise recommended for people of delicate disposition who rather like the songs of Celine Dion. However, 48 men and women with no particular love of razoring guitars, thundering drums and screamed lyrics from albums with titles […] See more

Renewable energy for industry is no sweat with new system

Scientists have developed a new system that makes using renewable energy for industry more viable. Heavy industry’s dependence on natural gas could be greatly reduced after new research that combined renewable energy and low-cost thermal storage to deliver heat for high-temperature industrial processes. Using renewable energy for industry which require high-temperatures has previously been thought of as a stumbling point for reducing emissions. Research indicates around 20 per cent of global fossil fuel emissions are […] See more

Coal-fired power stations ‘disrupt rainfall patterns’

Coal-fired power stations release more ultrafine particles than road traffic – and that can be dangerous for human health and change rainfall patterns. Modern coal-fired power stations produce more ultrafine dust particles than road traffic and can even modify and redistribute rainfall patterns, a new 15-year international study shows. The study indicates filtration systems on modern coal-fired power stations are the biggest source of ultrafine particles and can have considerable impacts on climate in several […] See more

Should we use AI in law courts?

A legal expert has suggested artificial intelligence should be used to assist sentencing in courts. A Melbourne law expert says it’s time to look at machine learning to identify bias in criminal sentencing. Criminal sentencing could be fairer with the help of machine learning, according to Professor Dan Hunter, from Swinburne University’s Law School. Hunter observed that sentencing generates a vast store of data, and the process is expensive for individuals and the system, making […] See more

Thank Earth’s magnetic field for water that gives you life

Finding water and life on exoplanets might be bound by the strength of their magnetic field. A study by scientists at ANU on the magnetic fields of planets has found that most planets discovered in other solar systems are unlikely to be as hospitable to life as Earth. Plants and animals would not survive without water on Earth. The sheer strength of Earth’s magnetic field helps to maintain liquid water on our blue planet’s surface, thereby […] See more

Newly found Aussie dinosaur confirms diversity in ancient rift valley

The space between Australia and Antarctica was once rich with herbivorous life. The discovery of a previously unknown species of small herbivorous dinosaur in the south-eastern corner of Australia confirms that life thrived in a vast rift valley that once existed between the continent and Antarctica, palaeontologists say. The dinosaur, identified from five fossilised jaw bones, would have been about the size of a wallaby, or a Labrador. The bones were unearthed from a site […] See more

Shared driverless cars could reduce traffic by 80%

A future of shared driverless cars could reduce the number of vehicles on the roads by 80%, says a transport expert. Shared driverless cars could make roads safer, transport cheaper, and reduce vehicle numbers dramatically, according to a transport expert. Work by Professor Hussein Dia from the Swinburne University Smart Cities Research Institute has suggested that more than 80% of cars could come off the road if fleets of shared, self-driving, electric vehicles become reality. Dia […] See more

The dingo is a true-blue, native Australian species

The much demonised dingo has an identity crisis, but the evidence shows it is clearly a native species of its own, say researchers. Of all Australia’s wildlife, one stands out as having an identity crisis: the dingo. But our recent article in the journal Zootaxa argues that dingoes should be regarded as a bona fide species on multiple fronts. This isn’t just an issue of semantics. How someone refers to dingoes may reflect their values […] See more
