Antarctic glacier thins and speeds up
One of the largest glaciers in Antarctica is growing thinner and retreating inland, spurring concerns that changes occurring along the coastline may be causing the ice stream to drain more material from the interior of the continent and send it out to sea, thus aggravating rising sea levels.

Living it up below the ice sheet?
A recent earthquake in Antarctica points toward geologic activity that could provide the energy necessary to incubate life in a liquid lake deep beneath the ice.

Lasers show atmosphere differs from models
New observations of the middle and upper atmosphere over Earth's polar regions may require scientists to revamp their mathematical models of temperature and other environmental conditions at high altitudes.

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.

Fluid Security—Overcoming Water Shortfalls in the 21st Century
About 70 percent of Earth’s surface is covered with water, some 1.4 billion cubic kilometers of it. Too bad almost 96.5 percent of it’s salty, and another 2 percent is locked away as ice in remote places such as Greenland and Antarctica. All told, just a little more than 1 percent of our planet’s water […]
