Co-principal investigator Jennifer Glass in her lab at Georgia Tech. She is holding a piece of sedimentary rock full of iron that rusted out of the ocean when breathable oxygen filled Earth's waters and air. Before there was ample breathable oxygen, chemically active iron was very available and very likely was involved in early evolution. It has since become less prevalent in many living systems.
