Isolation and characterization of a thermophilic, obligately anaerobic and heterotrophic marine Chloroflexi bacterium from a Chloroflexi dominated microbial community associated with a Japanese shallow hydrothermal system, and proposal for Thermomarinilinea lacunofontalis gen. nov., sp. nov. [PDF]
A novel marine thermophilic and heterotrophic Anaerolineae bacterium in the phylum Chloroflexi, strain SW7T, was isolated from an in situ colonization system deployed in the main hydrothermal vent of the Taketomi submarine hot spring field located on the

Miniaturized biosignature analysis reveals implications for the formation of cold seep carbonates at Hydrate Ridge (off Oregon, USA) [PDF]
Methane-related carbonates from Hydrate Ridge typically show several macroscopically distinguishable mineral phases, namely whitish aragonite, lucent aragonite, and gray micrite.

Clumped isotopes as fingerprints of microbial methane production pathways in marine sediments
Abstract Microbial methanogenesis in marine sediments produces significant amounts of methane from various substrates; however, identifying the active pathways in situ remains challenging. While the bulk and clumped isotopic signatures of methane from different pathways have been studied in pure cultures, these are difficult to compare with complex ...

Nonequilibrium Neutrino Oscillations in the Early Universe with an Inverted Neutrino-Mass Hierarchy
The annihilation of electron-positron pairs around one second after the big bang distorts the Fermi-Dirac spectrum of neutrino energies. We determine the distortions assuming neutrino mixing with an inverted neutrino-mass hierarchy.

Anaerobic oxidation of methane associated with sulfate reduction in a natural freshwater gas source [PDF]
The occurrence of anaerobic oxidation of methane (AOM) and trace methane oxidation (TMO) was investigated in a freshwater natural gas source. Sediment samples were taken and analyzed for potential electron acceptors coupled to AOM.

Dynamics of Iron‐Bound Organic Carbon Across Different Development Stages of Marine Cold Seeps
Abstract Marine cold seeps, where subsurface methane‐rich fluids discharge at seafloors, are “oases of life” that sustain highly active organic carbon (OC) and iron (Fe) cycling along the global continental margins. However, the interactions between Fe and OC and their impacts on the development and long‐term carbon preservation of cold seep ecosystems

Coenzyme F430, a nickel-containing tetrapyrrole, serves as a cofactor for methyl-coenzyme M reductase (MCR), which catalyzes both the final step of methanogenesis and the initial step of anaerobic oxidation of methane (AOM).

Synchronization in large directed networks of coupled phase oscillators
We extend recent theoretical approximations describing the transition to synchronization in large undirected networks of coupled phase oscillators to the case of directed networks.

Anaerobic methanotrophic communities thrive in deep submarine permafrost [PDF]
Thawing submarine permafrost is a source of methane to the subsurface biosphere. Methane oxidation in submarine permafrost sediments has been proposed, but the responsible microorganisms remain uncharacterized.
