Fits and Starts
New data identify some factors that influence the highly variable flow rates of ice streams, the megaglaciers that carry most of Antarctica's ice to the sea.

High Anxiety: Sudden solar flare highlights space risks
Measurements of energetic particles from an unusually strong solar flare that pummeled Earth early this year suggest that astronauts traveling or working in space might sometimes need to reach shelter within minutes of a warning.
