Angewandte Chemie recently published an exciting new paper authored by Icy Worlds team members. The paper examines the electrochemical gradients that form across self-assembling, out-of-equilibrium, inorganic precipitates in chemical gardens. This work helps pave the way for determining relevant properties of geological precipitates that may have played a role in hydrothermal redox chemistry at the origin of life, and materials applications that utilize the electrochemical properties of self-organizing chemical systems.

An illustration of ancient hydrothermal processes on a wet rocky celestial body was recently featured on the cover ofAstrobiology highlighting the publication of The Drive to Life on Wet and Icy Worlds authored by Dr. Michael Russell et al.
