Queensland’s alcohol laws increase preloading and fail to reduce violence

Alcohol laws in Queensland aimed at reducing violence had no effect at all. Instead they increased the amount people preload before heading out. Laws aimed at reducing alcohol-fuelled violence in Queensland entertainment areas have had no effect on violent crime, shows a three-year study. They have, however, encouraged people to preload before going out, in a surprise to no one. This has led the researchers to suggest a rethink is necessary if the laws are […] See more

The first Aussies arrived in a huge planned migration

Over 50,000 years ago a huge group of people planned and prepared for a mass migration to Australia, suggests new research. The size of the first population of people needed to arrive, survive, and thrive in what is now Australia is revealed in two studies. It took more than 1,000 people to form a viable population. But this was no accidental mass migration, as our work shows the first arrivals must have been planned. Our […] See more

Not always reaching your potential is okay, but overthinking it is a problem

It’s not failing to make progress that hurts, but negatively overthinking it. Having aspirations helps us navigate life in a meaningful and fulfilling way, but it can also cause psychological distress when hopes are left unfulfilled. New research from Edith Cowan University (ECU) has found that it’s not failing to make progress toward our ‘ideal-self’ that is problematic but rather the tendency to focus on that lack of progress in a negative way that leads […] See more

Australia, US and Brazil lead the world in weakening national parks

Australia has made over 1600 changes to its national parks in the last two decades, including reducing marine park protections. Since the first national parks were created in the nineteenth century, nearly 15% of the Earth’s land surface has been set aside in protected areas of one type or another. But these protections, researchers are finding, aren’t always as permanent as people might think they are. Since the set-asides began, 2,000,000 square kilometres of once-protected […] See more
