TL;DR: A combination of in situ investigations are presented, which show that for the crystallization of calcium phosphate these nanometre-sized units are in fact calcium triphosphate complexes and demonstrate how the existence of these complexes lowers the energy barrier to nucleation and unites classical and non-classical nucleation theories.

TL;DR: It is demonstrated that the simultaneous addition of Fe2+ and Fe3+ ions during apatite nucleation under controlled synthesis conditions induces intrinsic magnetization in the final product, minimizing the formation of magnetite as secondary phase, and potentially opens new perspectives for biodevices aimed at bone regeneration and for anti-cancer therapies based on hyperthermia.

TL;DR: It is suggested that water-generated tensile stresses may play a role in living collagen-based materials such as tendon or bone as well as technical applications, such as the fabrication of leather or parchment.

TL;DR: Cryo-preserved cells of the dominant coccolithophore Emiliania huxleyi are studied using state-of-the-art nanoscale imaging and spectroscopy to identify a compartment filled with high concentrations of a disordered form of calcium, suggesting an active role in coccoliths formation.

TL;DR: While investigating the role of magnesium ions in crystallization pathways of amorphous calcium carbonate, an unknown crystalline phase is unexpectedly discovered, hemihydrate CaCO3·½H2O, with monoclinic structure, which may have important implications in biomineralization, geology, and industrial processes based on hydration of Ca CO3.
