Scientists sequence genome of kind of organism central to biosphere's carbon cycle
The first ever genomic map of a diatom, part of a family
of microscopic ocean algae that are among the Earth's most important inhabitants, has yielded surprising insights about the way they may be using nitrogen, fats and silica in order to thrive. Diatoms, most of which are far too tiny to see without ma...
