Sound Velocities and Structural Transitions of Endmember and Fe, Al, Mg, Ti‐Bearing CaSiO3 Glasses Up to 23 GPa

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The study of silicate glasses is important to understand the physical and chemical properties of silicate melts under high‐pressure conditions relevant to planetary interiors. We conducted in situ Brillouin spectroscopy measurements on two endmember, low‐impurity CaSiO3 glasses and one Fe, Al, Mg, Ti‐bearing CaSiO3 glass up to 23 GPa.

Soil Organic Matter Stabilization by Polyvalent Cations in a Buried Alkaline Soil

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract Buried paleosols can store large quantities of organic carbon (C), much of which persists for millennia due to isolation from surface processes that promote decomposition. Subsoil organic matter (SOM) persistence is often enhanced by mineral associations and ionic conditions—particularly high clay content and polyvalent cations—that limit ...

Pliocene–Pleistocene Redox Evolution of the Peruvian Margin: A Multi‐Proxy Approach

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.
Abstract Due to upwelling of nutrient‐rich waters, the Peruvian Margin is one of the most productive regions of the global ocean, hosting one of the most pronounced and shallowest oxygen minimum zones. This combination of high productivity and low oxygen makes the Peruvian margin a critical site for reconstructing past environmental changes.

CRYSP: construction and visualization of crystal shapes in natural habits and on planar substrates

open access: yesActa Crystallographica Section B, Volume 82, Issue 1, Page 14-21, February 2026.
CRYSP is a software tool for the construction and visualization of crystal shapes in both natural habits and on planar substrates. It also supports morphologies associated with non‐crystallographic point groups.CRYSP has been developed as a crystallographic tool for the construction and visualization of crystal shapes. The input parameters for software

Biological Flora of Britain and Ireland: Geranium sylvaticum*

open access: yesJournal of Ecology, Volume 114, Issue 2, February 2026.
Geranium sylvaticum is a perennial forb of upland grasslands, woodlands and riverbanks in northern Britain, with scattered native occurrences also in Wales, central England and Northern Ireland. It has an extensive native range in Europe and Asia. The species is gynodioecious, with individual plants typically female or hermaphrodite.
