Physicists Advance Into Biology

St. Louis—Does biology need a “physicist” approach? Some physicists think so, and they're bringing their mechanistic philosophy to bear on questions ranging from how sharks electrically sense their prey to how cells of the immune system stick together. Biologists counter that finding universal laws of life is easier said than done. But many agree that a focus on mechanism may yield new insights into biological processes—while turning up some interesting new physics to boot.
