Serpentine Biocrust Microbes Maintain Nitrogen Cycling Under Drought and Heavy Metal Stress

Ecological Research, Volume 41, Issue 5, September 2026.
This study highlights the complex interplay between soil geochemistry and moisture availability in shaping microbial communities within wetter and drier serpentine and non‐serpentine biological soil crusts. It demonstrates that both factors influence the structure of nitrogen‐cycling microbial communities and the processes they mediate.

The SVP–FRO6 Module Integrates the Control of Leaf Senescence and Flowering in Arabidopsis

Plant, Cell &Environment, Volume 49, Issue 9, Page 7191-7209, September 2026.
ABSTRACT Plants coordinate major developmental transitions by integrating intrinsic genetic programs with environmental signals, where nutrient availability serves as a critical external factor shaping growth and fitness. Iron (Fe), an essential micronutrient for cellular respiration and photosynthesis, is strictly regulated through sophisticated ...

Solvent‐Guided Chiral Assemblies and Chemical Doping of OEG‐Functionalized Conjugated Polymers

Advanced Materials, Volume 38, Issue 45, 13 August 2026.
Solvent‐dependent aggregation pathways dictate whether conjugated polymers form chiral lyotropic liquid‐crystalline assemblies or achiral packed aggregates. Mapping solvent‐controlled β₁ and β2 states reveals that weaker backbone association favors β₁ aggregates and reorganizable twisted mesophases, whereas stronger backbone association favors β2 ...

The Baryonic Mass–Halo Mass Relation of Extragalactic Systems

The Astrophysical Journal
We combine data for extragalactic systems to quantify a relation between the observed baryonic mass M _b and the enclosed dynamical mass M _200 inferred from kinematics or gravitational lensing.

The complex history of NGC 1427A revealed by its star clusters and star formation history

Astronomy & Astrophysics
Star-forming low-mass galaxies in the dense environments of galaxy clusters provide opportunities to study how environmental effects such as ram-pressure stripping, tidal interactions, or galaxy mergers shape a galaxy’s star formation history.

Nitrogen Status Rewires Transcriptional Regulation of Dhurrin, a Dual‐Purpose Defense Metabolite in Sorghum bicolor

Plant Direct, Volume 10, Issue 8, August 2026.
ABSTRACT Dhurrin, a cyanogenic glucoside, plays an important role in Sorghum bicolor physiology and defense. The concentration of dhurrin in sorghum is influenced by both nitrogen status and stage of plant organ development. While nitrogen resupply activates the expression of genes for dhurrin biosynthesis, the molecular mechanisms underlying this ...

UPCluster-SZ: The Updated Catalog of Galaxy Clusters from the List of Planck Sunyaev–Zel’dovich Sources

The Astrophysical Journal Supplement Series
We present the updated galaxy cluster catalog of the second Planck catalog of Sunyaev–Zel’dovich sources (PSZ2) through the compilation of the data for clusters and galaxies with spectroscopically measured redshifts in the literature.

Statistical Survey of Cosmic Noise Absorption in Conjunction With Plasma Wave Measurements

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Using a decade of observations from the Canadian Geospace Observatory Riometer Network (GO‐RIO), we selected an east‐west subset of stations near L∼7 $L\sim 7$ to classify cosmic noise absorption (CNA) (a proxy for enhanced D‐region ionization) into two morphologies, simultaneous and drifting, based on the relative timing of signals across the

Massive star clusters in the semi-analytical galaxy formation model L-Galaxies 2020

Astronomy & Astrophysics
It has been established that a direct link exists between the formation history of star cluster populations and their host galaxies. However, our lack of understanding of the assembly of star cluster populations impedes our ability to use them as tracers
