Montana State team finds Yellowstone alga that detoxifies arsenic

BOZEMAN, Mont. -- Arsenic may be tough, but scientists have found a Yellowstone National Park alga that's tougher. The alga -- a simple one-celled algae called Cyanidioschyzon -- thrives in extremely toxic conditions and chemically modifies arsenic that occurs naturally around hot springs, sa...

Green alga genome project catalogs carbon capture machinery

WALNUT CREEK, -The genome analysis of a tiny green alga has uncovered hundreds of genes that are uniquely associated with carbon dioxide capture and generation of biomass. Among the 15,000-plus genes revealed in the study are those that encode the structure and function of the specialized organell...
