Cyanobacteria are the only prokaryotes to have evolved oxygenic photosynthesis,
transforming the biology and chemistry of our planet. Genomic and evolutionary studies …

Phosphorus (P) is critical to modern biochemical functions and can control ecosystem
growth. It was presumably important as a reagent in prebiotic chemistry. However, on the …

The macronutrient phosphorus is thought to limit primary productivity in the oceans on
geological timescales. Although there has been a sustained effort to reconstruct the …

The ancestors of cyanobacteria generated Earth's first biogenic molecular oxygen, but how
they dealt with oxidative stress remains unconstrained. Here we investigate when …

Phosphorus is a limiting nutrient that is thought to control oceanic oxygen levels to a large
extent,–. A possible increase in marine phosphorus concentrations during the Ediacaran …

Iron formations (IF) represent an iron-rich rock type that typifies many Archaean and
Proterozoic supracrustal successions and are chemical archives of Precambrian seawater …

Saturn's moon Enceladus has a potentially habitable subsurface water ocean that contains
canonical building blocks of life (organic and inorganic carbon, ammonia, possibly hydrogen …

The emergence and expansion of complex eukaryotic life on Earth is linked at a basic level
to the secular evolution of surface oxygen levels. However, the role that planetary redox …

The integration of fossils, phylogeny, and geochronology has resulted in an increasingly
well-resolved timetable of evolution. Life appears to have taken root before the earliest …

A high level of organic and inorganic phosphorus exists in discharged circulating cooling
water (DCCW), therefore, the efficient removal of phosphorus from DCCW is necessary …
