(American Geophysical Union) Some light in Earth's aurora glow is polarized -- a state not thought possible for the aurora, new observations indicate.

The findings may improve understanding of Earth’s upper atmosphere, its magnetic field, and the energies of particles from the Sun.

If detected also in the atmospheres of the other planets, such polarization may help map the Sun's extended magnetic field, researchers say.

New satellite imaging research may help save the dwindling lemur population in the African nation of Madagascar.

Using satellite imagery, GIS and ecological and demographic data from the field, researchers have studied the effects of deforestation on the ringtailed lemur population in Madagascar during the last forty years.

Researchers studying cores of sediment collected 40 years ago have found evidence for magnetic field vortices in the Earth's core beneath the South Pole.

The results contrast with earlier studies at lower latitudes, and could lead to a better understanding of processes in the core.
