Biomolecules Enhance Metal Contents In Calcite

From shells to bones, the skeletons of organisms contain small amounts of impurity elements such as magnesium. Because the levels of these elements provide important clues to past environments, a considerable effort has focused on understanding how to relate impurity contents to the ancient environments in which an organism lived. In the October 31 issue of Science magazine, Allison Stephenson, a Ph.D.
