West Antarctica glaciers observed during an October 2014 NASA Operation IceBridge mission. New research shows valleys in the ocean floor enable warm, salty water to reach the undersides of glaciers, fueling their increasingly rapid retreat.

It's official: East Antarctica is pushing West Antarctica around.
Now that West Antarctica is losing weight--that is, billions of tons of ice per year--its softer mantle rock is being nudged westward by the harder mantle...
MIT scientists have determined the structure of an enzyme that is found in ocean microbes and can produce a precursor to methane.
