Seafloor Fossils Provide Clues To Climate Change
Sun, 08 Nov 2009 11:00:00 EST
Deep under the sea, a fossil the size of a sand grain is nestled among a billion of its closest dead relatives.

Are The Alps Growing Or Shrinking?
Fri, 06 Nov 2009 05:00:00 EST
The Alps are growing just as quickly in height as they are shrinking. This paradoxical result comes from a new study by a group of German and Swiss geoscientists. Due to glaciers and rivers, about exactly the same amount of material is eroded from the slopes of the Alps as is regenerated from the deep Earth's crust. The climatic cycles of the glacial period in Europe over the past 2.5 million years have accelerated this erosion process.
