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 ...

Enhancing IR‐MALDESI MSI Spatial Resolution Through Beam Constriction With a Ring‐Actuated Iris

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 16, 30 August 2026.
ABSTRACT Rationale Infrared matrix‐assisted laser desorption electrospray ionization (IR‐MALDESI) mass spectrometry imaging (MSI) enables label‐free, spatially resolved molecular analysis of biological tissues under ambient conditions. While improving spatial resolution is important for mapping fine tissue structures, mid‐infrared (IR) lasers are ...

Erosion of granular sediments by submerged impinging jets: Particle size effects and cohesion onset

open access: yesAIChE Journal, Volume 72, Issue 6, June 2026.
Abstract This study investigates the erosion behavior and modeling of glass particle beds under impinging jet conditions, with a focus on particle size effects and the onset of cohesion. Ultrasonic profiling is implemented to scan and measure static crater profiles.

Progressively Fenitised Schist and Carbonatitic Clasts From a Metasomatic Aureole Beneath the Alkalic Dunedin Volcano, Otago, New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Clasts of albite‐porphyroblastic quartzofeldspathic schist, derived from the Otago Schist basement, occur within the Port Chalmers Breccia, a diatreme at the centre of the Dunedin stratovolcano, New Zealand. Schists have undergone varying degrees of replacement reactions (at temperatures of 300° to >500°C) producing hornfelses, with Ca‐ and K‐enriched ...
