Potentiostatic Electrodeposition of Binder‐Free Ni–W Electrodes for Coupled Energy‐Saving Hydrogen Production and Urea Remediation

EcoMat, Volume 8, Issue 6, June 2026.
A binder‐free Ni–W nanostructured electrode is fabricated via controlled potentiostatic electrodeposition on carbon paper that aligns with circular economy principles. The electrode enables energy‐efficient hydrogen production coupled with urea remediation, achieving 100 mA cm−2 at 1.77 V and degrading 47% of urea over 30 h.

Active Galactic Nucleus Disks as Supernova Mufflers. I. Three-dimensional Local Hydrodynamic Models

The Astrophysical Journal
Supernova (SN) shocks that originate from stars on orbits embedded in dense active galactic nucleus (AGN) accretion disks evolve differently from those that occur in the interstellar medium.

Deletion of a Pax1 Sex‐Associated Genomic Region Associated With Adolescent Idiopathic Scoliosis Leads to Disc Degeneration, Instability, and Vertebral Rotation in Mice

JOR SPINE, Volume 9, Issue 2, June 2026.
Overview of the effects of Pax1‐SAR deletion on gene expression, IVD degeneration, and resultant scoliotic‐like curvature between sexes. Proposed mechanism of sex‐dependent changes in gene expression in females (right) and males (left), resulting in sex‐dependent disc degeneration and scoliotic phenotypes.

XMM-Newton Conclusively Identifies an Active Galactic Nucleus in a Green Pea Galaxy

The Astrophysical Journal
Green Pea galaxies are a class of compact, low-mass, low-metallicity star-forming galaxies in the relatively local Universe. They are believed to be analogs of high-redshift galaxies that reionized the Universe, and, indeed, the James Webb Space ...

Mapping Immunity With Cutting‐Edge Spatial Biology and Tissue Cytometry Innovations

MedComm, Volume 7, Issue 6, June 2026.
This review explores how spatial biology integrates multiplexed imaging and tissue cytometry to reveal immune organization within native tissue contexts. ABSTRACT The immune system operates within organized tissue landscapes, where spatial relationships between cells shape the nature and outcome of immune responses.

Fluid‐Driven Cohesive Strengthening: Critical Role of Reaction Kinetics as the Determinant for Frictional Stability

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Following an earthquake, faults lock and regain strength via a combination of healing mechanisms that include pressure solution, contact growth, and cementation. Fault healing dictates strength recovery during the seismic cycle and is therefore a key factor controlling earthquake recurrence intervals, stress drop, and other source properties ...

Active Galactic Nucleus Jet-inflated Bubbles as Possible Origin of Odd Radio Circles

The Astrophysical Journal
Odd radio circles (ORCs) are newly discovered extragalactic radio objects with an unknown origin. In this work, we carry out three-dimensional cosmic-ray (CR) magnetohydrodynamic simulations using the FLASH code and predict the radio morphology of end-on

Mapping Quartz and Feldspar Areal Abundance and Grain Sizes Using Integrated VTIR Data

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Mineral dust is sourced from arid regions around the globe, and its composition impacts regional and global environments by affecting radiation balance, cloud formation, nutrient deposition, and snowmelt. As such, mineral dust plays a key role in Earth's energy and biogeochemical budgets.
