From monitoring a deadly disease in endangered Tasmanian devils in real time, to tracking wildlife recovery after devastating bushfires that claimed the lives of up to three billion animals, AI has the potential to change the world for good.

Globally, micro- and nanoplastics and plastic additives are widespread across our food supply. While we have an understanding of how they get there, there remains a massive gap in what we know about their effects on our health.

While metal detectors are useful for detecting land mines, they can be fooled by buried metallic debris … plus some mines don't contain any metal. A new system is claimed to work better, by reading the molecular signature of explosives used in mines.

What do you do if a South American weed is choking up your local Australian waterways? In the case of the cabomba plant, scientists are enlisting the help of the weed's natural South American enemy, the tiny cabomba weevil.

If you could zoom way out to look at the universe at its largest scale, you’d see that it’s made up of a colossal cosmic web. Now, astronomers have detected shockwaves moving through this web, providing new insights into large-scale magnetic fields.

Models of the universe predict that supernova remnants should be far more common than they are. Now, a new image from sensitive radio telescopes reveal that the missing remnants are hiding in plain sight.

The UniWave sea platform is an artificial blowhole that harvests energy from ocean waves. Independent analysis now predicts it'll create some of the cheapest renewable energy on the market – and some of the most reliable and predictable, as well.

Australian scientists have discovered strangely folded diamonds in rare meteorite samples. In investigating how they came to form, the team found evidence that they were forged in a cataclysm on an ancient dwarf planet.

If you’ve seen the first images from the James Webb Space Telescope this week, you might have heard the term “gravitational lensing” being thrown around. But what does it mean exactly? And how can it help this new telescope make discoveries?

Although there's no doubt that marine plastic waste pollution is a major problem, there may be at least a small sliver of hope. According to a new study, plastic trash on Australian beaches has actually decreased by almost a third in recent years.
