Deriving continuous deglaciation chronology from infrequent historical outlines

Earth Surface Processes and Landforms, Volume 51, Issue 7, July 2026.
We present a software tool (R script) that interpolates continuous surfaces of time since deglaciation from historical glacier outlines. At user‐specified points, the results can be used to reconstruct the deglaciation history (distance to glacier surface), including glacier readvances.

Structural Analysis of a Nitrogenase Iron Protein from Methanosarcina acetivorans: Implications for CO₂ Capture by a Surface-Exposed [Fe₄S₄] Cluster

mBio, 2019
Nitrogenase iron (Fe) proteins reduce CO2 to CO and/or hydrocarbons under ambient conditions. Here, we report a 2.4-Å crystal structure of the Fe protein from Methanosarcina acetivorans (MaNifH), which is generated in the presence of a reductant ...

Influence of substrate freshness on metabolite dynamics and methane emissions from pig slurry during laboratory incubation

Journal of Environmental Quality, Volume 55, Issue 4, July/August 2026.
Abstract Freeze/thaw pretreatment is commonly applied to animal slurry samples in laboratory studies, but its impact on organic matter transformation and methane (CH4) emissions remains uncertain. In this study, slurry incubations were performed at 20°C with three treatments differing in freshness of feces, urine, and inoculum.

Effects of Phloroglucinol on In Vitro Methanogenesis, Rumen Fermentation, and Microbial Population Density

Tropical Animal Science Journal, 2019
This study investigated the effect of phloroglucinol (1,3,5-trihydroxybenzene) supplementation alone on methane production, rumen fermentation profiles, and microbial population structure of mixed in vitro cultures.

Rumen methanogenic archaea and their correlation with enteric methane emission in ruminant animals: A systematic review and meta‐analysis

JSFA reports, Volume 6, Issue 7, Page 265-279, July 2026.
Abstract Background Livestock, especially ruminants, are a major source of global methane emissions, primarily produced by methanogenic archaea during enteric fermentation. We performed a systematic review and meta‐analysis to account for factors that could influence the relationship between ruminal methanogenic populations and methane emissions, such ...

The Sheaths of Methanospirillum Are Made of a New Type of Amyloid Protein

Frontiers in Microbiology, 2018
The genera Methanospirillum and Methanosaeta contain species of anaerobic archaea that grow and divide within proteinaceous tubular sheaths that protect them from environmental stressors.

Tracing methane sources in shallow waters of the North Sea: Biogenic signatures and hydrocarbon transport near abandoned wells

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Numerous abandoned wells in the North Sea may provide gas, particularly methane (CH4), migration pathways by penetrating shallow, biogenic gas accumulations. However, related sampling campaigns have been largely contradictory and lack a substantial database. Research cruise MSM98 targeted the abandoned wells B18‐1, DOK 1‐X, B11‐2, THOR and D‐1

How much methane do coal seam gas ponds emit?

Environmental Research Communications
Ponds are often used to store significant volumes of water involved in coal seam gas (CSG) extraction, but methane emissions from these ponds in Australia are not well understood.

Is the methanogenic community reflecting the methane emissions of river sediments?—comparison of two study sites

MicrobiologyOpen, 2017
Studies on methanogenesis from freshwater sediments have so far primarily focused on lake sediments. To expand our knowledge on the community composition of methanogenic archaea in river sediments, we studied the abundance and diversity of methanogenic ...
