A Physically Motivated Framework to Compare the Merger Timescales of Isolated Low- and High-mass Galaxy Pairs Across Cosmic Time

The Astrophysical Journal
The merger timescales of isolated low-mass pairs (10 ^8 < M _* < 5 × 10 ^9 M _⊙ ) on cosmologically motivated orbits have not yet been studied in detail, though isolated high-mass pairs (5 × 10 ^9 < M _* < 10 ^11 M _⊙ ) have been studied extensively.

Investigating the Impact of Virtual Reality Panoramas on Children's Water Safety Knowledge and Interest and Enjoyment

Journal of Computer Assisted Learning, Volume 42, Issue 4, August 2026.
ABSTRACT Background Unintentional drowning is a leading cause of injury and death among children worldwide, and inadequate water safety education is a significant contributing factor. Innovative technologies such as virtual reality [VR] have the potential to teach children about safety and reduce the risk of accidental injury.

Semianalytic Orbits: A Practical Implementation of Lynden-Bell’s Planar Orbits and Extension to Vertical Oscillations

The Astrophysical Journal
We present a practical implementation of the perturbation theory derived by Lynden-Bell for describing, to arbitrary precision, the orbit of a particle in an arbitrary spherically symmetric potential.

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 ...

Unraveling the Electronic Structure of Silicon Vacancy Centers in 4H‐SiC

Advanced Functional Materials, Volume 36, Issue 58, 20 July 2026.
The electronic structure of the silicon vacancy in 4H‐SiC is probed via transient absorption spectroscopy, uncovering previously inaccessible excited states of the quartet and doublet spin channels, including the V2' transition. In combination with theoretical analysis, a comprehensive picture of the electronic structure is established.

Self‐Powered Flexible Triboelectric‐Gated Ion‐Gel Transistor for Neuromorphic Tactile Sensing and Human Activity Recognition

Advanced Materials, Volume 38, Issue 37, 2 July 2026.
A fully flexible ion‐gel‐gated graphene‐channel transistor driven by a triboelectric nanogenerator enables self‐powered tactile sensing and synaptic learning. Mimicking spike‐rate‐dependent plasticity, the device exhibits frequency‐selective potentiation and depression, supporting rate‐coded neuromorphic computation even under flex.

The Nearly Universal Disk Galaxy Rotation Curve

The Astrophysical Journal
The universal rotation curve (URC) of disk galaxies was originally proposed to predict the shape and amplitude of any rotation curve (RC) based solely on photometric data.

A Bifunctional T3SS‐Effector Simultaneously Cleaves Host MAP Kinase and Inhibits PPM1A Phosphatase

Advanced Science, Volume 13, Issue 37, 3 July 2026.
Pathogenic bacteria exploit the metalloprotease effector NleD to subvert host defenses. Structural, biochemical, and infection analyses reveal a bifunctional mechanism by which NleD binds and inhibits the host phosphatase PPM1A while preserving its proteolytic activity against MAPKs.
