The genetic blueprints for four strains of phytoplankton -- some of the world's smallest photosynthetic organisms -- have been unraveled, a development that could improve climate modeling and the creation of new energy sources.
The U.S. has initiated research into a near-limitless energy source that has the potential of ending America?s dependency on foreign fuels but could, if improperly used, cause devastating damage to the environment.
Scientists believe there is a vast and as yet untapped source of energy locked in mud at the bottom of the ocean. They say frozen natural gas produced by deep sea bacteria has built up over thousands of years to provide the huge energy reserve.
