Read a German medical student. Paul early was fascinated with what he learned about dies in his anatomy, classes, in the eighteen seventies, just as some dies stick to cotton, but not the wool.

If the ride I could be found and put into the bloodstream would attack the harmful bacteria like a magic bullet leaving the regular cells. Untouched early spent most of his career developing. This idea in nineteen ninety nine he developed the first safe and effective drug to treat syphilis in people polars work on the chemical affinity of dies and his magic bullet idea who had all the way to a self drugs and other edible attics. Still in use today. This moment of science comes from Indiana University, where on the web at a moment of science dot org. I'm Don glass.
