By removing a gene to stunt cane toads at their tadpole stage, scientists hope they may have found a way to make the invader kill its own species.

The endangered orange-bellied parrot has lost 62 per cent of its genetic diversity and can only be saved by breeding with another species or editing its genes, a study suggests.

There are calls for a report to be released into potential damage to ancient rock art, before final approval is given to a major Woodside gas project.

Soil moisture has declined more than 2,600 gigatonnes since 2000, making a greater contribution to sea level rise than Greenland's melting ice sheets.

Sharks were thought to be silent, but scientists have recorded a New Zealand species making a clicking noise.

The serendipitous discovery of an exquisitely preserved fossil near Gulgong in NSW provides a glimpse into the evolution of Australian fish around 15 million years ago when the area was a tropical lake.

A new study suggests nutrient-rich crocodile poop could be benefiting wetland vegetation in the Top End while predation pressure limits feral pig damage.

The discovery of a 3.47-billion-year-old crater in WA's Pilbara region pushes back the age of the earliest-known impact site on Earth by more than one billion years.

The deadly H5N1 strain of bird flu travelled 6,600 kilometres over the sea to Kerguelen Island, which is just 440km from Australia's Heard Island.

Environment Minister Tanya Plibsersek is being taken to federal court by a conservation group over failure to list recovery plans for 11 threatened species.

The ban on the eastern blue groper has been widely criticised for failing to address climate-related pressures, with the fisheries watchdog admitting 'limited numbers' were being harvested by anglers even before it was made illegal. 

Your body could be prematurely ageing if you live in a location with as many as 190 days of extreme heat a year, according to a new US study.

Australian research has found a fluorescent film placed on top of "super cool" roof materials can solve glare problems while maintaining a comfortable temperature inside homes.

Western Australia has been hit by marine heatwaves since August, and now coral is bleaching in large areas along the coast from World Heritage-listed Ningaloo Reef to Ashmore Reef.

Numbers of eastern blue groper have halved in shallow waters around the Sydney coast since 2008, but are stronger in deeper water a new study has found.

The idea of a perfectly cooked egg is subjective, but Italian scientists think they have cracked a method for optimising flavour and texture in both yolk and whites.

Despite the energy innovations of artificial intelligence newcomer DeepSeek's models, AI power requirements as a whole are predicted to rise.

Projectiles flying faster than bullets from a blast 130 times bigger than the global nuclear stockpile helped form giant lunar canyons, according to a new study.

The expansion of the Roman empire to Greece 2,100 years ago coincided with a rise in lead pollution as a by-product of an increased demand for metals, according to some of the earliest traces of of lead still detectable in the ocean today.

A number of animals, plants and an entire ecosystem were added to Australia's extinction watch list in 2024. We look at the new species under threat.

The discovery of a close relative of the world's most popular psychedelic fungus suggests magic mushrooms came from Africa about 1.5 million years ago.

Scientists say more than 9,000 non-marine invertebrate species have gone extinct in Australia since Europeans arrived in 1788.

Last year eclipsed predicted temperatures. Now a new study suggests the extra warming occurred when the Earth became less reflective due to a drop in low cloud cover.

New modelling reveals some outer reefs will stay 1 degree Celsius cooler than surrounding areas in coming decades — but it's not clear how their coral colonies will fare.

The origin of the strange clearing, which is still visible today, was detected by a scientist trawling through satellite data.
