Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

Fish Scales: A Multifunctional Biomaterial from Nature

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

Larval Dispersal: Vent Life in the Water Column [PDF]

open access: yesOceanography, 2012
Visually striking faunal communities of high abundance and biomass cluster around hydrothermal vents, but these animals don't spend all of their lives on the seafloor.

Metatranscriptomics analysis of silicon transporters highlights underappreciated contributors to silica cycling in the Baltic Sea

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract The biotic component of the marine silica cycle strongly influences global biogeochemical cycling. Active uptake of dissolved silicic acid (dSi) occurs via silicon transporters (SITs), first characterized in diatoms but widely distributed in eukaryotes. Studying SITs and SIT‐like (SIT‐L) gene transcripts provides insights into the dynamics and

Synchrotron‐Based X‐Ray Tomography of Strontium Phosphate Chemical Gardens

open access: yesChemSystemsChem, Volume 8, Issue 5, September 2026.
Synchrotron‐based X‐ray tomography at the DanMAX beamline (MAX IV laboratory) is able to address challenges related to in situ observations at high spatial (sub‐micron) resolution in the field of chemical gardens or non‐equilibrium systems in general. The results therefore reflect a buoyancy‐linked mechanism of growth as well as the mineralization of ...

Widespread Association of Ciliates Colonizing Gills of Shrimps Inhabiting Vents and Seeps Across the Pacific Ocean

open access: yesJournal of Eukaryotic Microbiology, Volume 73, Issue 5, September/October 2026.
ABSTRACT Bacterial symbiosis is well‐documented in chemosynthesis‐based ecosystems, but associations with microeukaryotes remain overlooked. In this study, using scanning electron microscopy and 18S rDNA barcoding, we investigate the presence, diversity, and biogeographic patterns of ciliate epibionts associated with two deep‐sea caridean families ...

High-resolution bathymetry coupled with 3D models of hydrothermal vents from opportunistically-acquired imagery: Aurora vent field, Arctic Ocean

open access: yesJournal of Maps
Active venting at the Aurora hydrothermal field was first located in 2014. In July 2023, the AUV/ROV Nereid Under Ice (NUI) expanded the known size of the Aurora hydrothermal field, discovering 7 ‘black smokers’ together with associated lower-temperature

Significant Imbalance Between Human Activities and Ecosystem Services in the Tibet Autonomous Region of China: Evidence From an Improved Coupling Coordination Degree Model

open access: yesLand Degradation &Development, Volume 37, Issue 14, Page 10255-10271, 30 August 2026.
ABSTRACT Maintaining balanced interactions between humans and ecosystems in plateau regions is critical to achieving global sustainable development. However, existing methodologies are insufficient to fully elucidate the complex coupling and coordination relationships between human activities and ecosystems, as well as the sustainable development ...

Seismic Exploration for Magmatic Brine Lenses: An Example From Soufrière Hills Volcano, Montserrat

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The majority of metallic ore deposits are related to processes associated with ancient or modern volcanic systems. Beyond geothermal energy production, volcanoes also represent a potential resource of critical metals, including those required for carbon‐neutral technologies. Geothermal metals occur in subsurface fluid reservoirs fed by surface

From o‐Phenylenediamine to Flavin Derivatives: A Potential Prebiotic Carbon Skeleton Expansion With Formaldehyde, Cyanide, and CO2

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 16, 18 August 2026.
A Strecker‐type reaction of aromatic ortho‐diamines with various aldehydes and cyanide assembles the bicyclic amidine core of flavin‐derived heterocycles under mild conditions. Subsequent oxidation, radical or photochemical cyanation, carboxylation with CO2, and CO2‐mediated cyclization build the three‐ring alloxazine scaffold. This sequence provides a
