Glaciers not on simple, upward trend of meltingTwo of Greenland's largest glaciers shrank dramatically and dumped twice as much ice into the sea during a period of less than a year between 2004 and 2005. And then, less than two years later, they returned to near their previous rates of discharge.

Animal Studies In The Land Of The Midnight SunThe temperature hovers around freezing, but the sun is up for 24 hours each day. How do animals living in the continuous light of the Arctic summer know when to sleep and when to be active? Do they maintain a 24-hour cycle of rest and activity, or does living in continuous light alter their circadian rhythm?
Answering these questions may improve our understanding of biological clocks -- the internal, genetically programmed cycle of rest and........Go to the Science-blog (Added on 2/8/2007 10:03:54 PM)
