  • Iron-sulfur (FeS) proteins are involved in electron transfer and CO2 fixation. Here, the authors show that FeS clusters can form spontaneously in the presence of the amino acid cysteine, in conditions similar those expected in Hadean alkaline hydrothermal vents, suggesting a plausible mechanism of their emergence at the origin of life.

  • Intense solar radiation on desiccated desert soils can cause a short circuit in biogeochemical cycles leading to the release of CO2and nitrogen oxides. Here, the authors show that this can be linked to the production of soil superoxide radicals, which then produce peroxides and hydroxyl radicals.
