New Magnetite Reference Material for SIMS δ18O Measurements and a Study of Precision and Accuracy Due to Crystal Orientation Effects

Geostandards and Geoanalytical Research, Volume 50, Issue 2, Page 391-406, June 2026.
Key Points A new magnetite reference material (PF21mt) is available for δ18O measurements by SIMS. Reproducibility of measurement results in two laboratories suggest orientation bias of ±2‰ (2s) at 20 keV. Repeatability improves to ±1‰ (2s) when using a 13 keV protocol, suggesting reduced orientation bias. In situ isotope ratio measurements provide the

Commercial clays in cosmetic formulations for hair care: Characterization and application to improve the mechanical properties of hair fibre

International Journal of Cosmetic Science, Volume 48, Issue 3, Page 549-561, June 2026.
The shampoo and conditioner bar formulations enhanced hair gloss, promoting softness, improved cuticle alignment, and effective protection of hair shafts against external aggressors. Findings from mechanical properties measurements indicate that the clay‐containing formulations enhance the mechanical strength of hair, contributing to stronger and more ...

Tracking Dehydration Reactions and Fossil Fluid Flux in Shear Zones Using Garnet Microstructures

Journal of Metamorphic Geology, Volume 44, Issue 5, Page 394-414, June 2026.
ABSTRACT Shear zones act as preferential fluid pathways during prograde and retrograde stages of metamorphism. Nonetheless, we still have limited knowledge of the drainage and permeability of natural settings. The preserved signature of fluid in exhumed rocks provides insights into fluid flow during burial and exhumation.

Low temperatures and high water/rock ratios in asteroid (101955) Bennu's history based on X‐ray powder diffraction of returned samples

Meteoritics &Planetary Science, Volume 61, Issue 6, Page 1077-1094, June 2026.
Abstract Samples returned by NASA's OSIRIS‐REx mission from the carbonaceous asteroid (101955) Bennu hold clues about conditions in the early solar system and the formation of planetary bodies. Initial investigation of Bennu samples found that they are rich in phyllosilicates and other secondary minerals formed during aqueous alteration of a larger ...

Redundant and Flexible Electron Transfer Pathways Underlie MsrPQ‐Mediated Repair of Oxidized Periplasmic Proteins

Molecular Microbiology, Volume 125, Issue 6, Page 493-505, June 2026.
This study investigates in vivo the role of the flavin reductase Fre as an electron supplier to the periplasmic methionine sulfoxide reductase system MsrPQ. ABSTRACT The MsrPQ system is essential for the repair of oxidized methionine residues in periplasmic proteins, ensuring bacterial resistance to oxidative stress and envelope integrity.
