Migration governance without immigration detention is desirable and achievable. Eliminating all detention will universally benefit citizens, migrants and everyone in between.
Patching concrete sidewalks, roads and bridges after every season of snow and ice is expensive. A team of engineers is now testing a new approach harnessing bacteria to patch the potholes and cracks.
When it snows, it pours – but why do municipalities treat the roads with salt? A chemist explains how salt affects water and ice.
An atmospheric scientist explains why water can do some strange-looking things at very cold temperatures, and what's different about snowfalls on Mars.
Antarctic sea ice cover fell to an all-time low recently and hasn't yet recovered. Why? The initial answers could lie in an unlikely place – the tropics.
Bombarding people with scientific information has little effect. Something else is needed to jolt us out of our current climate trajectory.
Water is one of very few chemicals that is found as a liquid, solid and gas at any time on Earth. These three states of water help explain why ice makes a cracking sound when water is poured over it.
Governments and private companies have been seeding clouds to create snow for decades, without proof that it actually works. A recent study peered into clouds in search of answers.
No matter how cold it is, you're lucky you don't live on Venus.
A new study has looked at why some ice users suffer psychosis and others don't.
Ig Nobels reward research that first makes you laugh and then makes you think. Investigating the internet meme of fluid felines fits the bill – and adds to the physics field of rheology.
When we think of methamphetamine-related death we tend to focus on overdose. The extent of the problem, however, extends far beyond drug toxicity.
Nobody wants faecal bacteria in their iced latte. But if you have an iced drink from a high street coffee chain, that's what you might get.
Let's take claims about the value of drug seizures with a grain of salt.
West Australian Labor leader Mark McGowan said his state has the "worst rate of methamphetamine usage in the country". We asked the experts to check the evidence.
Without doubt, crystal methamphetamine, like many drugs (including alcohol) is capable of causing immense harm. But when facts are distorted to create fear and stigma it helps no one.
There is no doubt that 2016 has been a record-breaking year for the Earth’s climate.
After record-breaking amounts of sea ice in Antartica, this year we're seeing record lows.
