Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

FEBS Open Bio, Volume 16, Issue 8, Page 1537-1549, August 2026.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

Microbial metabolic potential of hydrothermal vent chimneys along the submarine ring of fire

Frontiers in Microbiology
Hydrothermal vents host a diverse community of microorganisms that utilize chemical gradients from the venting fluid for their metabolisms. The venting fluid can solidify to form chimney structures that these microbes adhere to and colonize.

Using Photographs in Fishers’ Ecological Knowledge Research: A Review and Field Study on Small‐Scale Fishers’ Knowledge of Coastal Habitats in the Central Mediterranean Sea

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Fishers interact daily with coastal environments, which generate a deep understanding of habitat characteristics, species associations and ecological change. Fishers’ ecological knowledge (FEK) is therefore a critical source of insight for marine science, offering observations that uniquely complement scientific data and, when incorporated ...

Comparative Neuroanatomy of Hydrothermal Vent Shrimps: Ecological Differentiation Among Four Alvinocaridid Species

Journal of Comparative Neurology, Volume 534, Issue 8, August 2026.
Hydrothermal vent shrimps share a conserved brain architecture with enlarged mushroom bodies and terminal medullae, shaped by similar environmental pressures. Despite this similarity, some anatomical features near the brain vary between species, suggesting that some ecological factors, such as microhabitat and trophic strategies, also influence nervous

Concomitant Mineral Carbonation and CO2 Reduction in Short‐Term Water‐Basalts Reaction: Difference Between Basaltic Glass and Basaltic Crystals

Global Challenges, Volume 10, Issue 8, August 2026.
Short‐term CO2–water reactions show that crystalline basalt undergoes more extensive carbonation than basaltic glass and is associated with detectable H2 and higher CO and CH4 concentrations. This contrast is consistent with the greater early reactivity of Fe‐ and Mg‐bearing crystalline phases, indicating that basalt mineralogy influences coupled ...

Green‐Synthesized Silver Nanoparticles Against Acinetobacter baumannii: A Systematic Review of Antibacterial Activity, Mechanisms of Action, Toxicity, and Antibiofilm Effects

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Schematic overview of the main antibacterial mechanisms proposed for green‐synthesized silver nanoparticles (AgNPs) against Acinetobacter baumannii. The figure summarizes the phytosynthetic pathway used to produce AgNPs (right panel) and the major reported antibacterial effects, including reactive oxygen species generation, oxidative stress, membrane ...

Reappraisal of Holocene Caldera Resurgence at Campi Flegrei (Southern Italy): A Long‐Lived Magma‐Driven Resurgent Dome System

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Caldera systems commonly experience inner resurgence, which shapes patterns of volcanic activity. However, incomplete reconstructions of past ground deformation can lead to incorrect recognition of precursory signals. The Campi Flegrei caldera (Italy) provides an exceptional opportunity to address this issue as uplifted marine sediments ...

Aluminum Phyllosilicate and Jarosite Formation Through Alteration of Reworked Al/Si‐Rich Volcaniclastic Sediments in Nili Fossae, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract Aluminum phyllosilicates occur in 1–10s of km2 exposures of Noachian (∼3.7 Ga) rock across Mars and typically appear stratigraphically above Fe/Mg‐phyllosilicates. These units have been proposed to represent pedogenic basalt weathering sequences.
