Northwestern University researchers have cracked one of the secrets of tooth decay. In a new study of human enamel, the materials scientists are the first to identify a small number of impurity atoms that may contribute to the enamel’s strength but also make the material more soluble. They also are the first to determine the

White and black balls indicate C atoms with four and three adjacent C atoms, respectively. view more  Credit: University of Tsukuba Tsukuba, Japan – Researchers at the University of Tsukuba used computer calculations to design a new carbon-based material even harder than diamond. This structure, dubbed “pentadiamond” by its creators, may

Ion channels and membrane transporters are in the business of moving ions and small molecules across cellular membranes. They are essential for metabolic and cellular homeostasis, and for a host of biological signaling pathways. “Both these classes of membrane proteins are extremely important for our health,” observes Nieng Yan, the Shirley M. Tilghman Professor at
