In Situ Atomic‐Scale Observation of Preferential Premelting at Oxide Crystal Defects

open access: yesSmall, EarlyView.
Under an external stimulus (e.g., an electron beam irradiation), premelting preferentially initiates at the planar defects in crystalline materials, thereby altering the local atomic and electronic structures. [Correction added on July 21, 2026, after first online publication: The graphical abstract figure has been updated.] ABSTRACT Under certain ...

Glass from Teniky (Madagascar): Geochemical Evidence for Multiple Production Systems and Long‐Distance Exchange in the Mediaeval Indian Ocean

open access: yesArchaeometry, EarlyView.
ABSTRACT The inland rock‐cut site of Teniky, located in the Isalo massif of southern Madagascar, represents an exceptional archaeological context recently dated to the 11th–12th centuries ad, corresponding to the early phases of settlement on the island.

Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference

Swiss Practice Recommendations for Chronic Prurigo Including Prurigo Nodularis

open access: yesInternational Journal of Dermatology, EarlyView.
Chronic prurigo, including prurigo nodularis, is a chronic, often treatment‐refractory condition characterized by persistent pruritus and chronic scratch lesions. Advances in the understanding of its underlying pathophysiology have enabled the development of novel targeted therapies; however, management remains challenging due to the expanding range of

(Ultra)high‐Pressure Metamorphism in Sedimentary Versus Basaltic Rocks: Insights From a Variscan Mélange in the South Carpathians

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT Reconstructing the pressure–temperature–time (P–T–t) evolution of (ultra)high‐pressure rocks is essential for constraining subduction and collisional dynamics. Subduction zones are often investigated using basic eclogites, whereas nonbasic high‐pressure rocks remain comparatively understudied, potentially hindering a comprehensive ...

Spectroscopic analysis of bacterial photoreactivation

open access: yesPhotochemistry and Photobiology, Volume 101, Issue 2, Page 494-504, March/April 2025.
This study investigates the effectiveness of fluorescence and Raman spectroscopy in detecting bacterial photoreactivation. Fluorescence spectroscopy shows limitations, because the intense fluorescence of tryptophan and tyrosine masks fluorescence emitted by thymine molecules.

Depth of DNA photodamage in human corneas exposed to 222 nm or 254 nm UV

open access: yesPhotochemistry and Photobiology, EarlyView.
Representative confocal 3D image of a section of a human cornea showing nuclei in blue (Hoechst 33342) and green, which was assigned to cells exhibiting Alexa555 conjugated to anti‐CPD antibody. The depth of photodamage was measured in Z‐stacks of the human corneal epithelium after exposure of the anterior surface to 50 or 100 mJ/cm2 at 222 or 254 nm ...
