Morphogenesis of the diamond-type stereom microlattice and the origin of saddle-shaped minimal surfaces in the echinoderm skeleton Echinoderm endoskeleton has a unique trabecular microstructure, called stereom, which can exhibit highly ordered geometries. A striking example of the…

Protoreaster nodosus (aka chocolate chip sea star🍪) has an unusual "diamond-type” stereom. How is it formed?

Metal porphyrins are ring molecules that form chlorophyll and hemoglobin. An Fe atom occupies the center of a heme, Mg the center of a chlorophyll, Ni the center of #Abelsonite. These molecules have diverse optical properties and biochemical functions.

Calcium-rich seawater affects the mechanical properties of echinoderm skeleton - Communications Earth & Environment Oceanic chemistry changes have made echinoderm skeletons weaker, making them more prone to damage from physical disturbances, predatory attacks, and taphonomic processes, according to experimental, ge...

📝In our latest paper, we talk about how seawater composition (specifically, Mg/Ca ratio) affects mechanical properties of sea urchin spines. Here’s the link: www.nature.com/articles/s43...
