Nobel Prize in Chemistry goes to 2 scientists who solved a century-old molecular problem

STOCKHOLM (AP) — Henri B. Kagan and Kenso Soai won the Nobel Prize in chemistry Wednesday for their efforts to resolve mysterious mirror images in chemical molecules.Many molecules of life come in versions that look alike but aren’t exactly identical, like right and left hands.
