South-west Australia relies on groundwater for three-quarters of its water use. But a new study of the region’s caves has found a drying climate is having a dramatic impact on this precious resource.
In the late 1980s, well diggers in Mali struck a rich source of naturally-created hydrogen. Now prospectors are scouring South Australia, looking for natural hydrogen.
By timing radio pulses from an array of galactic pulsars, scientists see hints of gravitational waves from supermassive black hole pairs in a breakthrough that may reveal hidden details of galaxy evolution.
The 2021 Pacific Northwest heatwave outstripped even the most severe climate prections. A new study simulated 45,000 years of weather at Seattle Tacoma airport to try and figure out why.
Large language models have been shown to ‘hallucinate’ entirely false information, but aren’t humans guilty of the same thing? So what’s the difference between both?
Marine life known as zooplankton might be the biggest problem with getting carbon cycling right in climate models. The potential variations in carbon uptake are greater than global transport emissions.
Scientists have detected a 30% slowdown of the deep ocean currents that form in Antarctica, with profound consequences for Earth’s climate, sea level and marine life.
Quantum machine learning models could help us create AI systems that are almost impenetrable by hackers. But in the hands of hackers, the same technology could wreak havoc.
Knowing where a weed has come from can improve its management, but this quest can be challenging. CSIRO detective work revealed an unusual pathway for the introduction of South African bitou bush.
Solar thermal technology has the potential to provide both long-duration storage and industrial heat, yet it has been largely overlooked in the Australian context. That is about to change.
In a plot reminiscent of the 2004 movie The Day After Tomorrow?, Australian scientists are warning that the Southern Ocean’s deep “overturning” circulation is slowing and headed for collapse.
Macquarie Island isn’t just a windswept rock halfway to Antarctica. It’s a globally unique home to dozens of bird and marine mammal species, hence the government’s plans to give it greater protection.
The largest birds that ever lived on Earth, elephant birds have a spotty fossil record. But understanding them could help protect Madagascar’s biodiversity.
