Copper acquisition from mineral promotes aerobic methane oxidation

Communications Earth & Environment
Aerobic microbial methane oxidation plays an important role in the global carbon cycle. This process is catalyzed by enzyme methane monooxygenase. Particulate methane monooxygenase requires copper as a cofactor.

Engineered Metal–Organic Frameworks‐Based Materials for Environmental Detection

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
Engineered metal–organic frameworks (MOFs) regulated by various material modification strategies are discussed for environmental contaminant detection under different sensing mechanisms, providing future improvements of MOFs in environmental detection. Sensitive and selective detection of contaminants is crucial for environmental protection.

Microbial diversity and biogeochemical interactions in the seismically active and CO2- rich Eger Rift ecosystem

Environmental Microbiome
The Eger Rift subsurface is characterized by frequent seismic activity and consistently high CO2 concentrations, making it a unique deep biosphere ecosystem and a suitable site to study the interactions between volcanism, tectonics, and microbiological ...

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.

Sampling across large-scale geological gradients to study geosphere–biosphere interactions

Frontiers in Microbiology, 2022
Despite being one of the largest microbial ecosystems on Earth, many basic open questions remain about how life exists and thrives in the deep subsurface biosphere.

Different Ferromanganese Concretion Morphologies Host Distinct Microbial Communities and Metal Accumulation Patterns in the Baltic Sea

Environmental Microbiology, Volume 28, Issue 7, July 2026.
We investigated how microbes influence the metal accumulation and release in Fe‐Mn concretions from the Gulf of Finland using microcosm incubation experiments. We studied three main concretion morphotypes: crust, discoidal, and spheroidal. Microbes enhanced metal accumulation in discoidal and spheroidal morphotypes.

Saline Permafrost and Cryopegs as Potentially Important Sources of CO2—Assessing Organic Carbon Mineralization Potentials on the Alaskan Coastal Plain

Global Change Biology, Volume 32, Issue 7, July 2026.
Incubation experiments reveal that potentially carbon‐rich saline permafrost and cryopegs from Arctic coastal plains exhibit CO2 production potentials comparable to active layers. This could substantially shift greenhouse gas balances, as salinity is currently not accounted for in permafrost carbon assessments.

Metagenomics deciphers diagenetic processes of ferruginous mineralization in the deep biosphere

Communications Earth & Environment
Ferruginous conditions in the Precambrian oceans gave rise to ancient iron formations that contain the oldest recognized traces of life in the form of mineral biosignatures and isotope imprints.

Goethite Reduction by a Neutrophilic Member of the Alphaproteobacterial Genus Telmatospirillum

Frontiers in Microbiology, 2019
In tropical iron ore regions, biologically mediated reduction of crystalline iron oxides drives ongoing iron cycling that contributes to the stability of surface duricrusts.
