Nearly 60 years after a radiation-leaking reactor was removed from a US Army base on the Greenland ice sheet, the military is exploring portable nuclear reactors again.
Complex questions over environmental protection and resource extraction require the signatories to give the future of the treaty much more serious attention.
Bubble-net feeding is when whales blow bubbles from their nose to encircle their food, trapping their prey into a tight ball. A citizen scientist was the first to capture this behaviour in Australia.
The Arctic region is warming much faster than the rest of the planet. The rapid loss of ice affects the polar jet stream, which influences weather patterns across the northern hemisphere.
If emissions continue at their current pace, Antarctica will cross a threshold into runaway sea rise when today’s kids are raising families. Pulling CO2 out of the air later won’t stop the ice loss.
Antarctic research has historically been a bastion of men from Europe and North America. Only now is the field opening up to women and people of colour. And there’s a way to go yet.
Microphones on the seafloor recorded life under the Antarctic ice for two years – inadvertently catching seal trills and chirps that are above the range of human hearing. Could they be for navigation?
‘Antarctic cities’ residents care deeply about the continent, with environmental concerns outweighing economic priorities. Asked about its future, they feel a mix of hope, pessimism and sadness.
Paleontologists have discovered fossil remains belonging to an enormous ‘toothed’ bird that lived for a period of about 60 million years after dinosaurs.
