  • Fangs are segments of the spider mouthparts, which are used to inject venom into prey and are required to sustain large mechanical loads. Here, the authors perform experiment-driven simulations, so to understand the correlation between the multiscale structural gradients and the biomechanical function of the fang.

  • A new carbonate phase calcium carbonate hemihydrate was recently discovered and characterized, but exclusively as a synthetic material. Here the authors find that it exists in nature, albeit transiently, on the surface of growing nacre and coral skeletons, and show that 2 amorphous and 2 metastable crystalline nano-minerals form before biominerals settle into their stable crystals.

  • Coccolithophores are unicellular marine algae that produce calcitic particles inside their cells. Here the authors study cells of the dominant coccolithophore Emiliania huxleyiand identify an intracellular compartment that is filled with high concentrations of a disordered form of calcium.
