Tetrahedral iron can help clays exchange electrons about ten times faster

Smectites are clay minerals that can contain large amounts of structural iron. Unlike iron oxides, they do not dissolve when their iron is reduced, so they can be reduced and reoxidized many times. This makes them a recyclable pool of redox-active iron that supports microbial res

Chang’e-6 lunar soil contains a surprising magnetic time capsule

Scientists studying Chang’e-6 lunar soil have discovered a previously unknown magnetic mineral in natural Moon samples: a form of metallic iron called γ-Fe. Found inside tiny impact-glass particles, the nanoscale iron can preserve a stable magnetic signal, potentially acting like

Powerful simulations reveal how the first stars changed the universe

Ultra-detailed simulations are showing how the first stars lit up the dark Universe and seeded space with elements such as carbon, oxygen, and iron. The MEGATRON project could bridge JWST observations of the earliest galaxies with chemical clues preserved in ancient stars today.
