The term stroad is portmanteau of street and road. Stroads try to be both a thoroughfare for vehicles, and a place for people. Typically they fail at both, and the result is unpleasant for everyone.

The first thing to remember is that all smoke is harmful. Typically, if you can smell smoke, it’s at a level where it’s impacting your health. Gabriel da Silva, Associate Professor of Chemical Engineering, The University of Melbourne Licensed as Creative Commons – attribution, no derivatives.

Whale strandings are undoubtedly sad events. But with the help of science, the body can be disposed of in a way that doesn’t harm nature or people.

I’ve studied stress in marsupials. Here’s why banning koala cuddles is a good idea – backed by the scientific evidence on koala handling and stress. Edward Narayan, Senior Lecturer in Animal Science, The University of Queensland Licensed as Creative Commons – attribution, no derivatives.

On the day of a blackout, a trial of vehicle-to-grid technology proved both the capacity of electric vehicles to support grid stability and the importance of exactly when vehicles are charged.

Contrary to popular belief, new research shows the abrupt, often gale force wind changes known as “southerly busters” are becoming more frequent, but less severe, as the climate changes.

Fatal crocodile attacks are extraordinarily rare in Australia – and there is no evidence to suggest their numbers are too high. Brandon Michael Sideleau, PhD student studying human-saltwater crocodile conflict, Charles Darwin University Licensed as Creative Commons – attribution, no derivatives.

Keeping the lights on in Australia is not an easy task – and adding nuclear to the mix would add new complications. Asma Aziz, Senior Lecturer in Power Engineering, Edith Cowan University Licensed as Creative Commons – attribution, no derivatives.

It has been particularly cold this week, with a record low temperature recorded in Tasmania. Such records are increasingly rare as average temperatures continue to rise.
