Sulfur-cycling microbes could lead to new possibilities in river-wetland-ocean remediation

Researchers propose a conceptual framework for understanding the diversity and composition of sulfur-cycling microbes in river-wetland-ocean continuum. They recommend developing new cultivation methods and studying life strategies, communities, and adaptations to improve ecosystem functioning through microbiome engineering.

New marine sulfur cycle model after the Snowball Earth glaciation

Researchers propose novel sulfur cycle model incorporating volatile organosulfur compounds to explain global occurrence of superheavy pyrite. The Cryogenian interglacial interval saw sulfidic oceans with pervasive VOSC generation, leading to vertical isotopic gradients and superheavy pyrite precipitation.

Rethinking early atmospheric oxygen

Researchers propose a more complex biological oxygen cycle on early Earth, with sulfur isotope signals persisting in ocean sediments long after oxygen accumulation. This 'memory effect' could blur dating of the Great Oxidation Event and provide new insights into early life.
