What paths do quantum particles, such as atoms or photons, follow through quantum state space? Kater Murch of Washington University in St. Louis has used a superconducting quantum device to continuously and repeatedly record the paths the device took through quantum state space. From the cobweb of a million paths, a most likely path between two quantum states emerged, much as social trails emerge as people round off corners or cut across lawns between buildings. The research is featured on the cover of the July 31 issue of Nature.

Gregory P. Magarian, professor of law, sees two reasons for leaving states with some power over the criminal law of marijuana.

Barbara Schaal, PhD, dean of the Faculty of Arts & Sciences at Washington University in St. Louis and the Mary-Dell Chilton Distinguished Professor, is one of 15 scientists from academia and industry named to the new Foundation for Food and Agricultural Research. U.S. Agriculture Secretary Tom Vilsack announced the foundation July 23.

People learn better and recall more when given the impression that they will soon have to teach newly acquired material to someone else, suggests new research from the Department of Psychology in Arts & Sciences at Washington University in St. Louis.
