Naturally Occurring CodY Variants Alter Ligand Binding, DNA Target Affinity, and Virulence in Clostridioides difficile

Molecular Microbiology, EarlyView.
Single amino acid substitutions in the global regulator CodY can alter nutrient sensing and virulence regulation in Clostridioides difficile. We show that the CodY(Y146N) and CodY(V58A) variants display altered ligand binding and reduced promoter binding, leading to derepression of toxin regulatory pathways and increased virulence in vivo.

‘Chrystalline Talk’: Thomas Browne's Poetics of Concretion and Mineral Plain Style

Renaissance Studies, EarlyView.
ABSTRACT This article charts the figuration, both material and rhetorical, of mineral bodies in early modern natural philosophy, paying particular attention to the second book of Thomas Browne's Pseudodoxia Epidemica (1646). It argues that concretions (stony calculi and crystals formed through the aggregation of physical matter) make manifest a mineral

Terrestrial Gamma‐Ray Flash Following Intense Negative Return Stroke Observed With BIMAP‐3D

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract We report ground‐based observations of a terrestrial gamma‐ray flash (TGF) associated with a strong negative cloud‐to‐ground lightning strike (‐CG) which occurred near Los Alamos National Laboratory (LANL) in New Mexico, USA. Gamma photons were detected by the Terrestrial High‐energy Observations of Radiation (THOR) instrument, developed at ...

Effects of plastic deformation on the properties of scintillation of Nal(Tl) crystal [PDF]

, 1960
The large single crystals of NaI(Tl) were produced by Stockbarger's and Kyropoulos' methods. The most adequate conditions for the growth of these crystals were studied. The thallium distributions in the crystal were measured, and the relation between the

Gallium nitride (GaN) scintillation response to fast neutrons and flash gamma rays and associated broadband photoluminescence

AIP Advances
Gallium nitride (GaN), a wide-bandgap semiconductor (3.45 eV), has emerged as a promising material for radiation detection due to its exceptional radiation tolerance, high thermal stability, and ultrafast scintillation response.

Toward a Greener Production of Materials: Water‐Minimized Synthesis of NiAl‐, NiFe‐, and CoAl‐Layered Double Hydroxides for Photocatalytic CO2 Reduction

Advanced Synthesis &Catalysis, Volume 368, Issue 13, 2 July 2026.
This study provides a water‐minimized strategy to synthesize layered double hydroxides using resonant acoustic mixing. The catalysts’ CO2 reduction performance strongly depends on their physicochemical properties, which can be controlled during the synthesis.

Integrative Multi‐Omics Analysis Reveals the Tumor‐Suppressive and Immunoregulatory Roles of SEMA5B in Prostate Cancer

BioFactors, Volume 52, Issue 4, July/August 2026.
This study identifies SEMA5B as a tumor suppressor in prostate cancer that suppresses the malignant phenotype, affects mitochondrial oxidative metabolism, induces cell cycle arrest and apoptosis, and is associated with the immune‐inflammatory tumor microenvironment, highlighting its potential as a biomarker and target for immunotherapy. ABSTRACT SEMA5B

Synthesis of Monazite‐Borosilicate Glass Composites by the Ceramic Method

International Journal of Ceramic Engineering &Science, Volume 8, Issue 4, July 2026.
A glass‐ceramic composite containing crystallites of La0.5Gd0.5PO4 (monazite) dispersed in a borosilicate glass matrix was synthesized using a one‐step ceramic synthesis method. ABSTRACT Glass‐ceramic composites are promising heterogeneous materials for the immobilization of high‐level nuclear waste.

Zr Doped GSO:Ce Single Crystals and Their Scintillation Performance [PDF]

, 2006
Cerium doped Gd2 SiO5 (GSO:Ce) single crystal is used as a scintillator for Positron Emission Tomography (PET). GSO:Ce has a good balance of every scintillation properties, but the only disadvantage is the decreasing light output by coloring caused by a ...
