Multiple Twinning in Nacre and Aragonite
Electron backscatter diffraction map of a cluster of geologic aragonite, exhibiting single, double, and triple twins. The whole cluster is approximately 2 cm wide. Colors indicate crystal orientations, so that pixels where the a‐, b‐, and c‐axis is perpendicular to the image plane are green, red, and blue, respectively.

Salinity–temperature interaction drives metabolic and energetic changes in an Arctic crustacean
Abstract The Arctic is shifting towards a prevalence of warm and more saline Atlantic‐like waters. These changes in the marine environment pose significant challenges for the ecophysiology of marine invertebrates. Here, we measured the metabolic enzyme activity of citrate synthase and lactate dehydrogenase, as well as the energy content and level of ...

Precursor Mineral Phases of Forming Mollusk Shell Nacre: A Study of Hydrated Samples
Mineral, organic phase, and water are the essential components in mollusk shell nacre formation. Their interplay is not well understood, because the hydrated material is difficult to observe at high resolution, under close to native conditions. Forming nacre is studied using environmental and cryo‐electron microscopy and hydrated ACC phases, together ...
