Genetically modified yeast mops up heavy metal pollution

Environmental scientists dream of eliminating pollution with natural resources, but thats tricky when it comes to heavy metals. Plants wont work for cleaning polluted water, and only some of them grow large enough to absorb those toxic materials. Researchers may have a relatively simple answer to the problem, though: genetically engineered bakers yeast. Their modified organism uses a cell membrane anchor, and peptides that bind with metals like cadmium, copper and nickel to ab…Read more
