Recent synchrotron spectromicroscopy methods reveal one formation mechanism and one toughening mechanism: Crystallization by particle attachment in diverse marine organisms, and its implications for changing ocean chemistry. Slight mis-orientation of nanocrystals in human enamel makes our teeth endure decades of mastication without breaking.
