  • Many animals display brilliant colors thanks to the precise formation of guanine crystals within specialized organelles. Here, the authors demonstrate that dynamic pH shifts orchestrate this process: an initially acidic lumen stabilizes amorphous, protonated guanine and subsequent alkalinization triggers its crystallization.

  • Organisms regulate biogenic crystal properties for various functions. Here the authors reveal the genetic and biochemical control of crystal morphogenesis in zebrafish iridophores, showing that the chemical composition, influenced by enzyme expression, determines crystal morphology and functionality.

  • Silica formation in diatoms is of interest for a range of different subjects from biomimetics to oceanography. Here the authors study the formation of silicified extensions in diatoms and find that unlike cell wall elements, that form in the cytoplasm, the extensions have a different formation mechanism outside the cytoplasm.
