Turnover of microbial cells, endospores, and organic carbon in ocean margin sediment affected by submarine landslides

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract The turnover rate of microbial cells drops steeply by increasing depth in the seabed, in accordance with the decreasing rate of organic matter mineralization. Bacterial endospore formation and germination may take place concurrently, yet their coupling to the mineralization rates during burial is poorly understood.

Microbial Populations of Stony Meteorites: Substrate Controls on First Colonizers

Frontiers in Microbiology, 2017
Finding fresh, sterilized rocks provides ecologists with a clean slate to test ideas about first colonization and the evolution of soils de novo. Lava has been used previously in first colonizer studies due to the sterilizing heat required for its ...

Global patterns in culturable soil yeast diversity

iScience, 2021
Summary: Yeasts, broadly defined as unicellular fungi, fulfill essential roles in soil ecosystems as decomposers and nutrition sources for fellow soil-dwellers. Broad-scale investigations of soil yeasts pose a methodological challenge as metagenomics are

An Integrated Assessment of European Soil Health and Restoration Potential

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT Soils host a significant proportion of biodiversity on Earth providing ecosystem functions vital to human well‐being, making it imperative to include them and their ecological features when addressing sustainability goals. We performed a comprehensive assessment of soil health across Europe by explicitly integrating biotic and abiotic ...

Dynamic Switchable and Transient DNA Condensates Driven by Aptamer‐Ligand or Ion‐Nucleobase Bridged Complexes

Small, Volume 22, Issue 31, 2 June 2026.
Switchable or transient formation and dissociation of the phase‐separated DNA microdroplets generated by metal ions or aptamer‐ligand complexes crosslinking Y‐shaped DNA frameworks and dynamically separated by counter ligands eliminating the bridging metal ions or biocatalysts degrading the aptamer‐ligand complexes, are introduced.

Microbial Ecology of the Heterogeneous Terrestrial Deep Biosphere Over 4 years in the Deep Mine Microbial Observatory (DeMMO)

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract The deep continental subsurface hosts a large, diverse, and poorly characterized microbiome. The geochemistry and microbiology of deep subsurface sites are closely linked and influenced by geological, hydrological, and anthropogenic factors. The Deep Mine Microbial Observatory (DeMMO; Lead, SD) was established in 2015 to provide stable portals

Laurasian Seaway History During the Early Jurassic From Quantitative Mineralogy and Detrital Zircon Dating

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract The Laurasian Seaway comprises a N‐S oriented trans‐Pangaean corridor linking Tethys to the Boreal Sea during the Jurassic, and direction of water flow has been the subject of considerable debate. The Llanbedr (Mochras Farm) borehole, Cardigan Bay Basin, Wales, is a uniquely informative record that comprises an expanded deep‐marine silty ...

Barium Isotopes Indicate Spatiotemporal Heterogeneity of Marine Primary Productivity During the Toarcian Oceanic Anoxic Event

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The Toarcian Oceanic Anoxic Event (T‐OAE, ∼183 Ma) was characterized by globally enhanced organic‐carbon burial and a negative carbon‐isotope excursion (N‐CIE). However, the role of marine productivity at this time, and its spatiotemporal variability, is unclear.
