Controlled experiments are impossible in astronomy, as are direct measurements of physical properties of objects outside our solar system. So how do astronomers know so much about them?
There’s a flurry of excitement every time a comet comes into view from Earth. But what are these celestial objects, and where do they come from?
Desert dust storms are increasingly picking up materials like sewage, herbicides and other human-made waste and transporting them on tiny particles that are easy to inhale.
Levels of trace metals inside can be higher than the sources of contamination outside. It underscores the need for households to take care to prevent those contaminants being brought indoors.
Fifty years ago, the Salton Sea was a draw for boaters and fishermen; today it’s an ecological time bomb. Two water experts who served on a state review panel describe its proposed rescue plan.
This new exhibition at Hobart’s Mona captures Tomás Saraceno’s collaborations with research institutes.
New research reveals that the London Underground is polluted with small particles which may carry negative health effects for humans.
The first ever sound recording of a dust devil on Mars reminds us that there is a lot to learn about how they sculpt the landscape.
Atmospheric dust storms often follow wildfires and have serious impacts on human health and ecology.
It’s impossible to escape exposure to microplastics and a new study confirms they’re in household dust around the world. But the health risks appear surprisingly low, and vacuuming makes a difference.
It is best to leave your filth outside the door.
This is a transcript of The Conversation Weekly podcast episode published on January 27 2022.
Plus, what toxic heavy metals are lingering in household dust around the world? Listen to The Conversation Weekly podcast.
Trace metal exposure can lead to concerning neurocognitive effects in people of all ages.
The Centers for Disease Control has announced a new, stricter standard for lead poisoning in children, which will more than double the number of kids considered to have high blood lead levels.
Australians have been sending their dust to our DustSafe program for us to analyse. Here’s what we’ve learned so far — and what you can do to reduce your dust risk.
Those directly exposed to toxic dust and trauma on and after 9/11 carry with them a generation of chronic health conditions, which are placing them at higher risk during the pandemic and as they age.
More 9/11 responders died from physical and mental health issues after the terrorist attacks than on the day itself. And survivors are still suffering 20 years later.
We analysed the dust in 32 homes across Sydney, and found significant levels of microplastics. But having hard, non-varnished floors and vacuuming at least weekly might help.
