Gas hydrate-bearing sediments are highly sensitive to redox fluctuations, primarily driven by methane fluxes associated with gas hydrate decomposition or cold seep activity. These sediments serve as valuable archives, preserving records of past redox states and methane emission events. Trace elements and rare earth elements (REE) have been widely applied as proxies to reconstruct such environmental conditions. Anoxic, methane-...

Anaerobic oxidation of methane (AOM) is a key methane sink in marine sediments, driven by electron acceptors such as sulfate, nitrate, and metal oxides. Manganese (Mn) oxides, owing to their high oxidizing capacity and rapid turnover, are also recognized as critical oxidants in AOM. However, Mn-AOM has not been well reviewed although several relevant studies have been published. In this paper, current results about Mn-AOM are...

Cold seeps, featured by their extremely methane-rich sedimentary environments, play a significant role in the geological history and are common in marine sediments across the seafloor. Primary dolomite, possibly mediated by microorganisms, can be widely discovered in methane-rich environments. Hence, cold seeps may provide new insights into the ‘dolomite problem’, which has confused geologists for decades. Magnesium isotope ge...

Long non-coding RNAs (lncRNAs) are a recently discovered group of non-coding RNAs that play a crucial role in the regulation of various human diseases, especially in the study of nervous system diseases which has garnered significant attention. However, there is limited knowledge on the identification and function of lncRNAs in hepatolenticular degeneration (HLD). The objective of this study was to identify novel lncRNAs and d...
