Using a highly sophisticated atomic-scale imaging tool on a sea creature’s tooth, two researchers have peeled away some of the mystery of organic/inorganic interfaces that are at the heart of tooth and bone structure. They are the first to produce a three-dimensional map of the location and identity of millions of individual atoms in the complex hybrid material that allows the animal to literally chew rock.
