Time‐series multi‐omics analysis of micronutrient stress in Sorghum bicolor reveals iron and zinc crosstalk and regulatory network conservation

open access: yesPlant Biology, EarlyView.
Overlap between Fe and Zn responsive gene regulatory networks (GRNs) were found, indicative of micronutrient crosstalk, and conservation of root and leaf GRNs and genes suggests strong constraint on homeostasis networks in plants. Abstract Micronutrient stress impacts growth, biomass production, and grain yield in crops.

Importations et imitations de céramiques de l’Ouest de la Gaule au second âge du Fer en Île-de-France

open access: yesRevue Archéologique du Centre de la France, 2015
The recent discovery in the Île-de-France of imported pottery (sherds with stamped decoration), but also of possible copies of storage jars, or even three-legged tubs in privileged contexts and in a funerary complex, raises the question of links that ...

SIRT1 Prevents Ferroptosis in Corneal Epithelial Cells by Enhancing HIF1α Protein Stability in Dry Eye Disease

open access: yesAdvanced Science, Volume 13, Issue 26, 8 May 2026.
Hyperosmotic stress drives ferroptosis in corneal epithelium via SIRT1 downregulation. This work demonstrates that SIRT1 activation stabilizes HIF1α, which transcriptionally upregulates GPX4 to inhibit lipid peroxidation and cell death. The identified SIRT1/HIF1α/GPX4 axis reveals a novel defense mechanism and potential therapy for dry eye disease ...

Molecularly Engineered Phenoxazinone‐Skeleton Cascade‐Activated NIR Probes for Monitoring Fe2+/Viscosity in Ferroptosis‐Mediated Parkinson's Disease

open access: yesAdvanced Science, Volume 13, Issue 26, 8 May 2026.
A series of Fe2+/viscosity cascade‐activated NIR fluorescence probes (NP1–5) are synthesized, and NP3 is selected for its optimal properties. To verify application of NP3 in ferroptosis intervention in PD, PQR NPs, is constructed by NP3 and quercetin self‐assembling.

L’occupation funéraire au début du second Âge du Fer dans le Sud-Châlonnais : autour de la tombe aristocratique de Moncetz-Longevas La Commune (Marne)

open access: yesRevue Archéologique de l’Est, 2013
A diagnosis survey carried out in 2009 by Inrap in the municipality of Moncetz-Longevas (Marne) revealed remains linked to a protohistoric occupation. A grave found within a ring trench triggered an excavation by Éveha at the start of 2010.The operation ...

Sensing and Filtering Environmental Fluctuations: The Case of Biomolecular Condensates in Plants

open access: yesAdvanced Science, Volume 13, Issue 27, 13 May 2026.
The diversity of plant condensates reflects constraints of sessile organisms to coordinate postembryonic development with environmental adaptation. This review examines how plants employ condensates to integrate temperature, light, redox, and nutrient signals.

Dimethyl Ether as Circular Hydrogen Carrier: Low‐Temperature Steam Reforming Over Copper–Zeolite Bifunctional Catalysts

open access: yesChemCatChem, Volume 18, Issue 10, 27 May 2026.
ABSTRACT In the context of a green H2‐based economy, chemical H2 carriers are essential for efficient H2 storage and transportation. Among H2 carriers, dimethyl ether (DME) is a promising candidate due to its characteristics, such as non‐toxicity, easy transportation, high H2 storage capacity, and its circular nature by the reusability of CO2 formed ...
