Off the coast of Ireland, history was just made. While windpower is taking off, and could soon produce as much as 20% of America's power, harnessing energy from the ocean is still in it's infancy.

Irish scientists have isolated a bacterium that can convert a toxic waste product into safe, biodegradable plastic. This week, scientists Kevin O'Connor and Patrick Ward, of the Department of Industrial Microbiology at University College Dublin, announced that they have discovered a bacterial strain that uses styrene, a toxic byproduct of the polystyrene industry (which produces Styrofoam, among other things), as fuel to make a type of biodegradable plastic, polyhydroxyalkanoate, known as PHA.
