Constraining the Hydration of Clay Minerals and Abundances of Amorphous Phases in Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Both water and organic matter are required for the development and persistence of life. Phyllosilicates (clay minerals) have high surface areas that easily sorb water and organic matter. The Curiosity rover has investigated several hundred meters of stratigraphy in Gale crater, including where clays were detected from orbit.

GOES‐R Series X‐Ray Sensor (XRS): 2. On‐Orbit Measurements and Calibrations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract An X‐Ray Sensor (XRS) has been onboard each of the National Oceanic and Atmospheric Administration (NOAA) Geostationary Operational Environmental Satellites (GOES) since 1975. XRS measures full‐disk soft X‐ray irradiance in two wavelength bands, 0.05–0.4 nm and 0.1–0.8 nm.

Powerful Radio-loud Quasars Are Triggered by Galaxy Mergers in the Cosmic Bright Ages

The Astrophysical Journal
While supermassive black holes are ubiquitous features of galactic nuclei, only a small minority are observed during episodes of luminous accretion. The physical mechanism(s) driving the onset of fueling and ignition in these active galactic nuclei (AGN)

The Extremely Young Star Cluster Population In Haro 11

, 2009
We have performed a deep multi-band photometric analysis of the star cluster population of Haro 11. This starburst galaxy (log L_FUV = 10.3 L_sun) is considered a nearby analogue of Lyman break galaxies (LBGs) at high redshift.

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.

Evaluation of the SWAN Game‐Based Approach to Re‐Building Numeracy Skills in Aphasia: Feasibility and Preliminary Findings

International Journal of Language &Communication Disorders, Volume 61, Issue 3, May/June 2026.
ABSTRACT Background Numeracy difficulties are common in individuals with post‐stroke aphasia, yet assessments and therapies addressing these are limited. This study investigated the feasibility and effectiveness of SWAN, a game‐based digital intervention targeting foundational number language skills: counting and transcoding.

Insights into the Exoplanet Radius Valley from Host-star Ages, Activity, Chemistry, and Birth Radii

The Astrophysical Journal
The radius valley—a bimodal feature in the size distribution of close-in small exoplanets—is widely interpreted as a signature of atmospheric loss and therefore provides a key constraint on the formation and atmospheric evolution of these planets.

Evaluating the Color of Chocolate Chip Cookies: Comparative Performance of Instrumental Colorimetry, Digital Image Analysis, and Computer Vision Relative to Human Perception

Journal of Food Science, Volume 91, Issue 5, May 2026.
ABSTRACT Food color is commonly quantified using colorimeters; however, these instruments may be impractical in home‐based or small‐scale production settings. More accessible alternatives, such as digital image analysis and computer vision, may offer reliable color quantification when conventional instrumentation is unavailable.

Environmental Enrofloxacin Exposure as a Modifiable Driver of Mitochondria‐Mediated Intestinal Aging and Barrier Dysfunction

Aging Cell, Volume 25, Issue 5, May 2026.
Environmentally relevant enrofloxacin accelerates intestinal aging by impairing epithelial mitochondrial function, disrupting barrier integrity, and reshaping the gut microbiota. Mitochondrial restoration with pyrroloquinoline quinone alleviates hypoxia, inflammation, and gut damage.
