Analyzing marine sediment levels around Casey station between 1997 and 2015, Australian and Canadian scientists found that levels of multiple contaminants exceeded international quality guidelines.

Safe levels are exceeded in 13,000 kilometres of rivers globally, with ingredients potentially degrading into more persistent substances.

An unusual feeding technique only recently observed by scientists was documented nearly 2,000 years ago, a study suggests.

Two-thirds of Antarctica’s native species, including emperor penguins, are under threat of extinction or major population declines by 2100 under current trajectories of global heating, according to new research that outlines priorities for protecting the continent’s biodiversity.

Researchers say previous studies mistook the clitoris on female snakes as scent glands or underdeveloped versions of penises

Captive-breeding programs lead to shorter wingspans in birds and behavioural changes that leave animals more vulnerable to predators, a global study finds.

Researchers say their prototype produces hydrogen with greater than 99 per cent purity and works in air as dry as four per cent relative humidity.

Pollution generated by burning fossil fuels causes snow to darken, absorb more solar energy and melt faster.
