A critical role of heterotrophic bacteria in early diagenesis of carbonates through exopolymer degradation and calcium release

The Depositional Record, Volume 12, Issue 1, February 2026.
Exopolymeric substances (EPS) produced in the photic zone and surface sediments sequester calcium. Below the sediment surface, heterotrophic bacteria degrade EPS, releasing calcium resulting in carbonate precipitation. This process, which continues for millennia deep in the core, is an important sink for atmospheric carbon dioxide.

Domed‐rim microbial polygons and their preservation potential

The Depositional Record, Volume 12, Issue 1, February 2026.
Microbially induced sedimentary structures (MISS) derive through interactions between minerals and microorganisms. We define a domed‐rim MISS, morphologically distinct from abiotic mud cracks and demonstrate its potential for long‐term preservation. These structures represent promising biosignatures in ancient environments on Earth and potentially Mars.

Iterative Modeling via Structural Diffusion (IMSD): Exploring Fold‐Switching Pathways in Metamorphic Proteins Using AlphaFold2‐Based Generative Diffusion Model UFConf

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 2, Page 633-648, February 2026.
ABSTRACT Metamorphic proteins (MPs) can fold into two or more distinct spatial structures. Increasing interest in MPs has spurred the search for computational tools to predict proteins fold‐switching potential and model their refolding pathways. Here we address this problem by using the recently reported generative diffusion predictor UFConf, based on ...

Fracture‐Assisted Pressure Solution Creep of Granite: An Example From the Mont Blanc Massif, Western Alps

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Mont Blanc granite, as other deformed granites, has splitting properties attributed to two perpendicular planes: one formed by aligned fractures and the other by aligned micas in foliation planes. It is shown that this microstructure results from ductile deformation with stress‐driven dissolution of quartz and feldspar that passively ...

Si Isotope Fractionation in Metamorphic Rocks From Cryogenic Temperature Crystallographic Data and Quantum Phonon Model

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract In this study, we demonstrate that it is possible to fit the resilience at the high temperature limit using only the atomic mean square displacement determined from cryogenic temperature single crystal diffraction data. Our method introduces the Debye phonon model, under which the atomic mean square displacement displays quantum behavior at ...
