Although amorphous calcium carbonate represents an important biomineralization precursor, its structure has been difficult to understand. Now, amorphous calcium carbonate’s structure is shown to arise from the different bridging modes available to the calcium ions. This effective multi-well potential that drives calcium arrangements creates a geometric incompatibility between preferred Ca–Ca distances and frustrates crystallization.

In a classical Bardeen–Cooper–Schrieffer superconductor, pairing and coherence are established simultaneously below the critical transition temperature (T_c). But in the copper oxide high- T_c superconductors, a pseudogap extends above T_c. Spectral gaps arising from pairing precursors are qualitatively similar to those caused by competing states, rendering a standard approach to their analysis inconclusive. This paper reports that the spectral weight of the superconducting coherent peak increases away from the node following the trend of the superconducting gap, but then starts to decrease in the antinodal region.
