Horwitz Prize Awarded for the Discovery of Bacterial Cell Structure

Columbia University will award the 2012 Louisa Gross Horwitz Prize to Richard Losick, PhD, Joe Lutkenhaus, PhD, and Lucy Shapiro, PhD, for their collective work on the intricate, dynamic, three-dimensional organization of bacterial cells. Prior to their discoveries, the tiny bacterial cell was thought to be a “bag of enzymes” that held a jumbled mess of proteins and DNA within a “cell sap.”
