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.

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

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.

Antarctica’s gaining ice in some spots
Large portions of Antarctica are storing more snowfall than they once did.

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.

Letters from the August 6, 2005, issue of Science News
Empty threat? “Empty Nets: Fisheries may be crippling themselves by targeting the big ones” (SN: 6/4/05, p. 360) reads as if there is something to be alarmed about. By selectively catching large fish, we have reduced “the mean size [of food fish to] one-fifth of what it was.” This is not cause for alarm. It […]

Cool Birds
Emperor penguins go to such extremes to cope with life in Antarctica that they've inspired interesting science as well as a hit movie.

Spores record changes in ozone concentration
Decreasing concentrations of atmospheric ozone over Antarctica have triggered changes in the spores of a plant that grows in the region, a trend that could give scientists insight into ancient extinctions.
