The anaerobic oxidation of methane (AOM) in marine ecosystems is ubiquitous and largely
coupled to sulfate reduction. In contrast, the role of AOM in terrestrial environments and the …

Supergene enriched iron ore deposits in Brazil are typically blanketed by goethite-cemented
breccias that form a protective duricrust known as canga. Moderately hard, well …

Methylmercury (MeHg) contamination in paddy fields is a significant environmental issue
globally since over half of the population of our planet consumes rice. MeHg is a neurotoxin …

This present study investigated pork bone-derived biochar as a promising amendment to
reduce Cd accumulation and alleviate Cd-induced oxidative stress in rice. Micro/nanoscale …

Microorganisms in the terrestrial deep biosphere host up to 20% of the earth's biomass and
are suggested to be sustained by the gases hydrogen and carbon dioxide. A metagenome …

Phosphorus (P) can be retained in mineral association with ferrous iron (Fe) as vivianite, Fe
(II) 3 (PO 4) 2∙ 8 H 2 O, in lake sediments. The mineral is formed and remains stable under …

Neutrophilic microbial aerobic oxidation of ferrous iron (Fe (II)) is restricted to pH-
circumneutral environments characterized by low oxygen where microaerophilic Fe (II) …

This work considers the hypothetical viability of microbial nitrate-dependent Fe2+ oxidation
(NDFO) for supporting simple life in the context of the early Mars environment. This draws on …

Nanoparticles (NPs) are a key component of the earth system, and intentionally and
unintentionally produced in human activities. These NPs may have both positive and …

Toward the end of the Palaeoproterozoic era, over 10 9 billion tonnes of banded (BIF) and
granular (GIF) iron formations were deposited on continental platforms. Granules in iron …
