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

open access: yesPlant 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 ...

Latitude Survey of Neutrons and Muons to Determine Cosmic Ray Neutron Sensing Yield Functions

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Cosmic Ray Neutron Sensing (CRNS) is a ground‐based technique that utilizes epithermal neutron measurements as a proxy for environmental hydrogen content. Similarly to other ground‐based cosmic ray detectors (e.g., neutron monitors), CRNS detectors are affected by the solar cycle and space weather events.

Near‐Earth Cosmic Ray Modulation Index ϕ and Neutron Monitor Cutoff Rigidities at Hourly Cadence: Toward an Improved Monitoring of Solar‐Terrestrial Radiation Environment, Space Weather, and Space Climate

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Cosmic rays (CRs) are energetic particles originating from galactic and extragalactic sources. When arriving into the solar system and the Sun's heliosphere, they are diverted and modulated by the magnetic activity of the Sun. This modulation can be quantified by the modulation parameter ϕ $\phi $ determined with the Force‐field approximation (

Low Frequency Extensions of Cyclotron Maser Instability‐Generated Radio Emission: A Statistical View From Cassini at Saturn

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The Cassini spacecraft spent 13 years orbiting Saturn, quasi‐continuously measuring Saturn's radio emissions. One of the key elements of the radio spectrum at Saturn is the Saturn Kilometric Radiation (SKR), and several studies have been written on events called Low Frequency Extensions (LFEs) which represent strong, continuous extensions of ...

Chemogenetic Activation of G12 Signaling Thickens the Epidermis With Enhanced Barrier Function

open access: yesFASEB BioAdvances, Volume 8, Issue 8, August 2026.
In this study, we investigated the role of G12 signaling in the epidermis using a keratinocyte‐specific chemogenetic approach. Activation of G12 signaling promoted keratinocyte differentiation and enhanced epidermal barrier function by upregulating filaggrin, claudin‐1, and ceramide.
