We are the shelled creatures of the ocean, the oysters, mussels, clams, urchins and starfish. We require calcium carbonate in the form of aragonite and calcite to build our shells and skeletons, as do some species of zooplankton and phytoplankton, coralline algae and the coral reef building organisms. 1,174 more words

Futurity highlights cancer research at Washington University that shows promise in stopping the spread of tumors through the use of calcium carbonate nanoparticles.
Study shows how calcium carbonate forms composites to make strong materials such as in shells and pearls
The results show that such clumps become incorporated via chemical interactions with atoms in the crystals, an unexpected mechanism based on previous understanding. By providing insight into the formation of natural minerals that are a composite of both soft and hard components, the work will help scientists develop new materials for a sustainable energy future, based on this principle.
