Embodied, Enacted, and Multimodal: Exploring Science Teachers’ Metaphors in Authentic Classroom Contexts

Science Education, Volume 110, Issue 5, Page 1469-1496, September 2026.
ABSTRACT Over the past decades, science education research has extensively examined the role of metaphors in teaching and learning science. However, much of the existing research has focused on verbal manifestations of metaphors, thereby overlooking aspects of metaphors that may occur in non‐verbal form. This study reconceptualises metaphors as dynamic

Toward an Advanced Benchmark for Aerosol Radiative Forcing: A Chemically Resolved Sectional Aerosol Scheme in E3SMv3

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Aerosol radiative effects are the largest uncertainty in anthropogenic forcing estimates due to challenges in accurately representing aerosol properties and aerosol‐cloud interactions. In this study, we implement the Advanced Particle Microphysics module (APM) into the Energy Exascale Earth System Model (E3SMv3) to represent evolving size ...

Attenuation of LHAASO PeVatrons by the Interstellar Radiation Field and Cosmic Microwave Background Radiation

The Astrophysical Journal
“PeVatrons” refer to astrophysical sources capable of accelerating particles to energies around 10 ^15 electron volts and higher, potentially contributing to the cosmic-ray spectrum in the knee region.

Bianchi I Spacetimes in f(Q)‐Gravity

Fortschritte der Physik, Volume 74, Issue 8, August 2026.
ABSTRACT The Kasner spacetimes are exact solutions that are self‐similar and of significant interest because they can describe the dynamic evolution of kinematic variables near the singularity of the Mixmaster universe. The chaotic behavior of the Mixmaster universe is related to the Kasner relations.

Lunar Trailblazer Spacecraft Tracking and Mission Recovery Attempt: Characterization of Status and Behavior of a Non‐Cooperative Object in Cis‐Lunar Space

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Unexpectedly following launch, the Lunar Trailblazer mission experienced software anomalies that led it to orient solar panels away from the sun and lose communication with Earth. This paper describes efforts to determine the spacecraft state and attempt recovery of the mission's science at the Moon.

Comparing Monte Carlo Models of Impact Alteration of Planetary Atmospheres

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract One process that affects atmospheric surface pressure is impact bombardment. The evolution of a planet's atmosphere under impact bombardment is an open question. We use a Monte Carlo method to evolve a range (0.006–92.5 bar) of initial atmospheres at Mars, Earth, and Venus under bombardment of 5×106 $5\times 1{0}^{6}$ impactors using seven ...

Measurement of background radiation, cosmic ray flux and their hazard parameter of Baghdad city districts

Iraqi Journal of Physics, 2019
The aim of this work was directed to measure the cosmic ray (CR) flux and the background (BG) absorbed dose rate for districts of Baghdad city. The maximum values of CR flux was 2.01 (particle/cm2.s) registered for several Baghdad districts and the ...

Validation of ANCHOR Ionospheric Data Assimilation Model Using GIRO Ionosondes Within PyVALION Software

Radio Science, Volume 61, Issue 8, August 2026.
Abstract Accurate specification of the ionosphere is essential for mitigating the impacts of space weather on communication, navigation, and surveillance systems. ANCHOR is a newly developed ionospheric data assimilation (DA) model from the U.S. Naval Research Laboratory that fuses measurements from ionosondes, radio occultation, and Global Navigation ...
