  • Emerging sulfur isotope data divides opinion surrounding the Great Oxidation Event. Utilising computational approaches and additional data, Uveges et al. reconcile these disparities, offering a more refined framework of atmospheric oxygenation.

  • Earth’s surface underwent a dramatic transition ~2.3 billion years ago when atmospheric oxygen first accumulated during the Great Oxidation Event. Here, the authors find that biogenic methane and volcanic emissions played a vital role in the reduced Late Archean atmosphere.

  • Compound-specific carbon isotope measurements of the 1.64-billion-year-old Barney Creek Formation show an ecosystem dominated by cyanobacteria and heterotrophic bacteria. Isotope data for carotenoids suggest that the assembly of the reverse tricarboxylic acid cycle in Chlorobi occurred later.

  • The response of biogeochemical nitrogen cycle to Earth-surface oxygenation remains poorly known. Here, the authors show that aerobic nitrogen cycling was pervasive prior to the Great Oxygenation Event (GOE), but its evolution was complex, with diazotrophy prevailing and sustaining productivity after the GOE.
