I heard about this for the first time on NPR this morning. Three chemists split the Nobel Prize for chemistry for their work on chiral molecules. These molecules have two different forms, mirror images of each other. The forms usually appear in roughly even amounts in a substance. William S. Knowles, K. Barry Sharpless, and Ryoji Noyori worked out ways to make it easier to separate the different configurations of the same molecule. In medicine this is important because often only one of the two configurations is useful, the other is sometimes toxic. Thalidomide is probably the worst scenario: one form was useful as a sedative, the other caused horrible birth defects. A benign example is limonene: one form smells like oranges, the other like lemons or turpentine. Summaries of the work from the Nobel Institute are here and here.
