Subglacial lakes may not be isolated ecosystems
Large volumes of water may occasionally flow between the lakes that lie deep beneath Antarctica's kilometers-thick ice sheet.

Invasive, Indeed
Some people may live lightly on the land, but the demands of the world's population as a whole consume nearly a quarter of Earth's total biological productivity.

The Hunt for Antihelium
Scientists have been searching about 30 years for a single nucleus of helium made from antimatter, and although the discovery would imply that whole antimatter galaxies exist, the researchers' time could be running out.

Intrepid Explorer
A robotic torpedo called an autonomous underwater vehicle has provided scientists with an unprecedented look at the underside of an Antarctic ice shelf.

Antarctic birds are breeding later
Rising global temperatures are causing Arctic birds to breed earlier in the spring, but for Antarctic birds, the reverse is true.

Satellite makes finest map yet of Antarctica
Using data gathered by a satellite launched almost 3 years ago, scientists have assembled the most comprehensive high-resolution map of Antarctica that's ever been made.

Icy Heat: Satellites look at heat flow through Antarctica’s crust
Using satellite observations of Earth's magnetic field, scientists can estimate the amount of heat flowing upward through Earth's surface under kilometers-thick ice.

Ozone hole might not recover until the year 2065
The ozone-free zone that develops high in the atmosphere over Antarctica each summer as the result of the presence of chlorine- and bromine-containing chemicals may not heal until 15 years later than previously projected.

What’s Going on Down There?
In a 10-year, global effort, researchers exploring the unknowns of marine life have found bizarre fish, living-fossil shrimp, giant microbes, and a lot of other new neighbors.
