W.M. Keck Foundation funds study of friendly microbes

You could say that the Human Genome Project missed 99 percent of the genes in the adult body. That's because it didn't sequence genes belonging to the vast communities of bacteria that normally live on and in us. Now a $1.45 million grant from the W.M. Keck Found...
