Shock Deformation in Zircon, a Comparison of Results from Shock-Reverberation and Single-Shock Experiments [PDF]

The utility of the mineral zircon, ZrSiO4, as a shock-metamorphic geobarometer and geochronometer, has been steadily growing within the planetary science community.

Cooling‐Induced Rheological Weakening Along the Nascent Plate Interface—A Mechanism for Catastrophic Subduction Initiation?

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Subduction initiation often begins with slow, forced convergence, switches “on” catastrophically as the slab collapses into the mantle, and then evolves to steady‐state, self‐sustained sinking that drives global plate movements. Numerical models suggest that the collapse phase implies sudden weakening of the plate interface.

Brittle and Crystal‐Plastic Defect Dynamics of Calcite Single Crystals

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract The response of Earth materials to stress has a first‐order control on solid‐Earth dynamics ranging from earthquakes to volcanic eruptions to landslides. Thus, understanding the rheological behavior of minerals, preferentially at a micro‐scale to allow process‐based upscaling, has broad applications across the Earth sciences.

In Situ Microscale Shear Failure Mechanism in Hot Dry Rock Under Thermal Cycling

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract Induced shear failure is key for enhancing hot dry rock (HDR) resource exploitation, aiming to creating an extensive fracture network. Although the macroscopic shear behavior of HDR has been extensively investigated, its microscopic shear failure mechanisms remain unclear.

Mountain Degradation Mechanisms on Io Based on Geologic Mapping of the Cocytus Montes Region From JunoCam Imagery

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Periodic high‐resolution imagery of Io is essential for understanding its surface evolution, from volcanic eruptions to tectonic deformation to large‐scale mass wasting. Juno flybys in 2023 and 2024 obtained imagery of the surface with the JunoCam imager at 1.8 km/pixel spatial resolution, comparable to global observations from the Galileo ...

A preliminary Scanning Electron Microscope (SEM) study of magnetite surface microtextures from the Wahianoa moraines, Mt Ruapehu, New Zealand. [PDF]

, 2010
Scanning electron microscope (SEM) of quartz micro‐textures has routinely been used to identify the depositional environment of sediments in areas of former ice‐sheet glaciation.

Biogeochemical asymmetry and the diversification of tropical rain forests in Borneo: The endmember hypothesis

Functional Ecology, Volume 40, Issue 1, Page 4-14, January 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Mixed dipterocarp lowland tropical rain forests on Oxisols and Ultisols and heath forests on Spodosols are considered distinct vegetation types in Borneo. Here we present the endmember hypothesis of ecosystem diversification, which describes a continuum of forest ...

Cross‐Feeding of Carbon and Nitrogen Between Aquificales and Thermus in Hot Springs

Environmental Microbiology, Volume 28, Issue 1, January 2026.
Pampinifervens and Thermus populations are co‐distributed in hot springs in Yellowstone and Iceland. Genome reconstruction suggests Pampinifervens Flu05 cross feeds Thermus organic carbon and nitrogen, a phenomenon that was verified via co‐culture studies.

Structural analyses of ABA transporters give new impetus to the study of ABA regulation

Annals of Applied Biology, Volume 188, Issue 1, Page 11-21, January 2026.
Abscisic acid (ABA) regulates key physiological processes and coordinates abiotic stress responses. In the six decades since it was first described, a huge amount of work has been conducted on ABA synthesis, breakdown and signalling mechanisms. Recently, attention has been turned to the role of ABA transporters, and the elucidation in exquisite detail ...
