Were Viking landers blind to life?
The Viking landers may have missed potential signs of life when they explored Mars in 1976.

Glaciers give major boost to sea level
The ongoing disappearance of glaciers and other small ice masses worldwide makes a larger contribution to sea level rise than the melting of ice sheets on Greenland and Antarctica does.
- Paleontology
Of penguins’ range and climate change
Variations in the range of Adélie penguins along one section of Antarctica's coast during the past 45,000 years are a keen indicator of climate change there.

An unexpected, thriving ecosystem
A diverse group of creatures beneath an Antarctic ice shelf could give pause to researchers who infer past ecological conditions from fossils found in such sediments.
- Earth
Subglacial lakes may influence ice flow
The flow of water into and out of massive, ice-covered lakes in Antarctica may influence the speed at which the overlying glaciers move toward the sea.

Low Life: Cold, polar ocean looks surprisingly rich
The first survey of life in deep waters around Antarctica has turned up hundreds of new species and a lot more variety than explorers had expected.

Southern seas slow their uptake of CO2
In recent decades, the rate at which oceans in the Southern Hemisphere soak up atmospheric carbon dioxide has slowed.
