Recent research has hypothesized that hydrogen peroxide (H2O2) may have emerged from abiotic geochemical processes during the Archean eon (4.0–2.5 Ga), stimulating the evolution of an enzymatic antioxidant system in early life. This eventually led

Abstract Marine sedimentary rocks deposited across the Neoproterozoic Cryogenian Snowball interval, ~720-635 million years ago, suggest that post-Snowball fertilization of shallow continental margin seawater with phosphorus accelerated marine primary

Abstract Microbial anaerobic oxidation of methane coupled to the reduction of Mn(IV)-oxides, typically MnO2, derived from continental weathering and riverine transport has been proposed as a globally important sink of methane. However, the potential

A new aim for grassland management is to increase soil organic carbon (SOC) and to offset CO2 emissions by companies. This practice of carbon ranching may be informed by grazing-induced shifts in plant biomass and diversity which may foretell changes

Abstract One of the paradoxes of the Archean rock record is how evidence for oxidative continental weathering is plausible when the atmosphere lacked oxygen prior to the Great Oxidation Event ca. 2.5 billion years ago. We detected reactive oxygen spe

The authors discovered that proinflammatory senescent myeloid cells may recruit peripheral immune cells in the aged mouse brain. Their findings implicate senescent cell clearance as a strategy to counter aged brain inflammation and cognitive decline.
