Observational Evidence of Dust Evolution in Supernova Remnants: Size Redistribution toward Larger Grains in the Early Sedov Phase

The Astrophysical Journal Letters
Recent observations have revealed that dust is widespread and abundant in galaxies up to z  ≃ 8, significantly influencing their appearance and spectral properties.

A Two‐Step Artificial Intelligence Approach for Correcting Space Weathering Effects in the Lunar Reconnaissance Orbiter Diviner Christiansen Feature Image

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Space weathering substantially distorts the Christiansen feature (CF) observed by Lunar Reconnaissance Orbiter (LRO) Diviner thermal infrared radiometer, obscuring the intrinsic compositional and thermophysical signals of lunar surface silicate minerals.

Data-driven Stellar Intrinsic Colors and Dust Reddenings for Spectrophotometric Data: From the Blue-edge Method to a Machine Learning Approach

The Astrophysical Journal
Intrinsic colors (ICs) of stars are essential for studies on both stellar physics and dust reddening. In this work, we developed an XGBoost model to predict ICs with the atmospheric parameters T _eff , ${\rm{log}}\,g$ , and [M/H].

Asymmetric Shape Variability Biases Proportion Judgments With Icon Arrays

Cognitive Science, Volume 50, Issue 5, May 2026.
Abstract Icon arrays are graphical displays in which a subset of shapes are filled to represent the probability of an outcome (e.g., the probability of side‐effects from a medical treatment). Prior work has shown that the perceptions of probabilities can be more accurate with icon arrays compared to other formats.

Assessing the Effects of Composition and Surface Roughness on the Photopolarimetric Response of Planetary Regoliths

The Astrophysical Journal Supplement Series
This study is part of an ongoing project in which we experimentally examine the effect of composition (refractive index) and surface roughness on the scattering matrix elements of a set of well-characterized rough regolith simulants.

Establishing Biodigestate Based Fertilizer's Value Within the Agricultural Community: A Key Prerequisite of Bioenergy Commercial Viability

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
This research investigated the barriers and opportunities for biodigestate, a key by product of bioenergy production, as an input to commercial agricultural operations within New Zealand. The qualitative research examined in detail how the product fitted into the agricultural community.

The Flattest Infrared Extinction Curve in Four Isolated Dense Molecular Cloud Cores

The Astrophysical Journal Letters
The extinction curve of interstellar dust in the dense molecular cloud cores is crucial for understanding dust properties, particularly size distribution and composition.

Assessing corn response to sulfur fertilization in Kansas: Efficiency, optimum rate, and diagnostic tools

Agronomy Journal, Volume 118, Issue 2, March/April 2026.
Abstract Corn (Zea mays L.) response to sulfur (S) fertilizations remains difficult to assess due to the dynamic nature of S availability. This study evaluated corn response and diagnostic tools across 30 field sites in Kansas (Experiment 1; with and without S) and in complementary rate trials at two sites (Experiment 2; multiple S rates).

Probing the Distinct Extinction Law of the Pillars of Creation in M16 with JWST

The Astrophysical Journal Letters
Investigating the extinction law in regions of high dust extinction, such as the Pillars of Creation within the M16 region, is crucial for understanding the densest parts of the interstellar medium (ISM).
