More than two-thirds of Earth's remaining wilderness is in the hands of just five countries, according to a new global map. A concerted conservation effort is needed to save our last wild places.
In Antarctica, many countries want a piece of the action.

Sidney Jeffryes achieved a world first by establishing wireless contact between Antarctica and Australia. But his mental illness meant he gradually vanished from history - until now.

Mosses are the only plants that can withstand life in East Antarctica's frozen landscape. But a new study shows that life is getting even harder, as ozone loss and climate change make conditions even drier.
Most people will never visit Antarctica but music can evoke the continent in myriad ways.

Scientific research into the effects of climate change in Antarctica - and its history of intrepid exploration - is inspiring contemporary Australian composers.
In contrast to common perceptions, Antarctic seafloor communities are highly diverse. This image shows a deep East Antarctic reef with plenty of corals, sponges and brittlestars. Can you spot the octopus?

Life on the Antarctic seafloor is surprisingly diverse – and half of the species live nowhere else on Earth. Now scientists can accurately map this unique biodiversity.

A chance discovery of some kelp that floated for 20,000km before washing up on an Antarctic beach has opened up a new chapter in our understanding of the currents that swirl around the Southern Ocean.
Scientists have found that the bedrock underneath the West Antarctica Ice Sheet has the potential to rebound in response to melting faster than thought, which could act to stabilize the ice.
As the world prevaricates over climate action, Antarctica’s future is shrouded in uncertainty.

What will Antarctica look like in 2070? Will the icy wilderness we know today survive, or will it succumb to climate change and human pressure? Our choices over the coming decade will seal its fate.
Without floating sea ice, climate-weakened ice shelves are wide open to attack by waves.

Since 1995, several ice shelves off the Antarctic Peninsula have abruptly disintegrated. A new analysis suggests that these events are triggered when ice shelves lose their buffer of floating ice.

Last summer one of Antarctica's floating ice shelves calved an iceberg the size of Delaware – but scientists say other less dramatic changes reveal more about how and why Antarctica is changing.
This year 77 women took part in the largest all-female expedition to Antarctica as part of a leadership training program. Rough weather enroute put group decision-making skills to the test.
A life-like reconstruction of Llanocetus denticrenatus, the second oldest “baleen” whale ever found.

Baleen whales are some of the least likely mammals, supporting their massive bodies by filtering tiny prey. New evidence from an ancient fossil sheds new light on how baleen evolved.
