The atmosphere of the Archean eon—one-third of Earth's history—is important for
understanding the evolution of our planet and Earth-like exoplanets. New geological proxies …

Selenium (Se), which can be both hazardous and beneficial to plants, animals and humans,
plays a pivotal role in regulating soil-plant-human ecosystem functions. The biogeochemical …

Selenium (Se) is a naturally occurring metalloid element which occurs nearly in all
environments. Se is considered as a finite and non-renewable resource on the Earth. The …

Life requires a wide variety of bioessential trace elements to act as structural components
and reactive centers in metalloenzymes. These requirements differ between organisms and …

The rise of molecular oxygen (O2) in the atmosphere and oceans was one of the most
consequential changes in Earth's history. While most research focuses on the Great …

Microbial reduction of Se (IV) to Se (0) is extremely important for the detoxification of
selenium oxyanion, but the reductive mechanism is still controversial. In this study, the …

Adsorption plays an important role in the biogeochemical cycling of selenium (Se) in natural
environments and Se isotope fractionation during adsorption is a significant but poorly …

Abstract Neoproterozoic (1,000–542 Myr ago) Earth experienced profound environmental
change, including 'snowball'glaciations, oxygenation and the appearance of animals …

It has been proposed that an “oxygen overshoot” occurred during the early Paleoproterozoic
Great Oxidation Event (GOE) in association with the extreme positive carbon isotopic …

The later stages of Earth's transition to a permanently oxygenated atmosphere during the
Great Oxidation Event (GOE;∼ 2.43–2.06 Ga) is commonly linked with the suggestion of an …
