Key metabolites secreted by Chlorella vulgaris alleviate salt stress in soybean seedlings

Journal of Integrative Plant Biology, EarlyView.
Chlorella vulgaris secretes exosome‐derived linolenic acid and inosine, which alleviate salt stress and enhance salt tolerance in soybean seedlings by activating stress‐responsive signaling networks. ABSTRACT Soil salinization is a major abiotic stress factor that reduces soybean production.

Molecule by Molecule Characterization of a Polymer Molecular Mass Distribution via Mass Photometry

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
Mass photometry (MP) was utilized to achieve label‐free, molecule‐by‐molecule measurement of the full polymer molecular mass distribution (MMD) of a synthetic polymer without the need for sample fractionation. The ability to elucidate the full MMD in minutes, as opposed to having only specific moments of the MMD acquired in hours via chromatography ...

GALACTICNUCLEUS: A high-angular-resolution JHKs imaging survey of the Galactic center

Astronomy & Astrophysics
Context. The center of the Milky Way presents a unique environment of fundamental astrophysical interest. However, its extreme crowding and extinction make this region particularly challenging to study.

Optical and Near‐Infrared Photometry of Distant Galaxy Clusters

The Astrophysical Journal Supplement Series, 2002
We present optical and near-infrared photometry of 45 clusters of galaxies at 0.1 < z < 1.3. Galaxy catalogs in each cluster were defined at the longest wavelenth available, generally the K-band, down to approximately two magnitudes below M*. We include finding chart images of the band used for catalog definition.

Hyperaldosteronism in Mice Lacking the Distal Polybasic Tract of the γ‐Subunit of the Epithelial Sodium Channel During Sodium Restriction

Acta Physiologica, Volume 242, Issue 6, June 2026.
ABSTRACT Aims The epithelial sodium channel ENaC consists of the subunits α, β, and γ and is activated at an individual channel level by proteolytic processing. Murine γENaC contains a distal polybasic tract 186RKRK mediating proteolytic ENaC activation by serine proteases in vitro.

Black in Impressionism and Post‐Impressionism: Art, Color Vision, and Psychophysics

Color Research &Application, Volume 51, Issue 3, May/June 2026.
Black has engendered controversy in 19th Century color theory and in Impressionist and Post‐Impresssionist painting. The neural mechanisms of blackness perception are being revealed through contemporary psychophysics. ABSTRACT From Paleolithic cave art to modern abstraction, artists have used black not merely as a neutral tone, but as a powerful ...

Genetic Diversity, Population Structure, and Environmental Influences in Nepeta glomerulosa: Implications for Conservation in the Irano‐Turanian Region

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Nepeta glomerulosa shows moderate genetic diversity with three main clusters and significant admixture, highest in the Alborz Mountains, suggesting it may be the center of origin. High genetic differentiation (Gst = 0.4199) points to limited gene flow and possible self‐pollination, with geographic isolation shaping population structure.

Keck Observations in the INfrared of Taurus and ρ Oph Exoplanets And Ultracool Dwarfs (KOINTREAU) I: A Planetary-mass Companion and a Disk-obscured Stellar Companion Discovered in Taurus

The Astronomical Journal
We present the first discoveries from Keck Observations in the Infrared of Taurus and ρ Oph Exoplanets and Ultracool dwarfs (KOINTREAU), an adaptive optics imaging survey of young stars in the Taurus and ρ Oph star-forming regions using the Keck infrared
