Nobel Prize in chemistry awarded to Kagan and Soai for untangling mirror images in molecules
STOCKHOLM (AP) — Scientists Henri B. Kagan and Kenso Soai won the Nobel Prize in chemistry Wednesday for untangling mysterious mirror images in molecules, a discovery that has been used to develop countless drugs and transformed modern medicine. Many molecules come in versions that look alike but are not exactly identical, like right and left hands. One mirror image of the chemical carvone smells like mint, for example, while the other has a whiff of caraway, a spice often used in rye bread.
