The oceans
Very cool story in the Washington Post about the changing science of the oceans. Using GPS and bar codes on creatures they are discovering all sorts of new things including a school of tuna the size of Manhattan that was living off the coast of New Jersey.
In 2006 alone, researchers found a single school of 8 million fish the size of Manhattan off the New Jersey coast as well as the hottest-known hydrothermal vent, which sustains marine life even as it spews liquid from below the sea floor at 765 degrees Fahrenheit.
