Beneath the surface of soils and waterways, iron oxide minerals have long been silent arbiters of carbon's fate — but only now are scientists beginning to read their logic. New research reveals that goethite, one of the most common iron minerals on Earth, acts as a molecular filter, selectively removing the most resistant organic compounds from solution and leaving behind the molecules microbes can most readily consume. This reshaping of the organic menu fundamentally alters how quickly and completely carbon is broken down — and whether it returns to the atmosphere or remains stored in place.
