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. Kagan, who is from France, and Soai, from Japan, found ways to make chemistry pick a side, describing and designing reactions to produce the desired mirror image.
