Distinct Adrenal Medulla Activity in Germ‐Free Versus Conventional Male Rats Under Acute and Chronic Stress

Journal of Neurochemistry, Volume 170, Issue 8, August 2026.
The study investigates the influence of gut microbiota on adrenal responses to stress in male rats, comparing germ‐free (GF) and specific pathogen‐free (SPF) models. The results show that stress caused a significant increase in epinephrine production in GF rats.

Impact of the invasive diatom species Cymbella janischii on riverine microbial biofilm communities and a potential role of bacterially produced zeatin

Journal of Phycology, Volume 62, Issue 4, Page 1221-1239, August 2026.
Abstract The diatom Cymbella janischii is an invasive species in Japan, causing nuisance blooms by forming thick mats in rivers. To date, there are no documented studies on the microbiome associations in C. janischii mats or the processes that drive bloom formation.

Raman analysis of organic refractory materials after energetic processing: Evidence for amorphous carbon on TNOs and comets

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 1994-2015, August 2026.
Abstract Amorphous carbon (αC) is found in various extraterrestrial particles, including those thought to originate from the outer Solar System. αC can form through two main processes involving C‐rich materials: exposure to energetic charged particles and thermal processing.

Nanoscale space weathering features in mature lunar soil revealed by TEM and APT

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 2048-2072, August 2026.
Abstract Space weathering significantly alters the optical, chemical, and structural properties of lunar regolith at micro‐ and nanoscales; yet detailed nanoscale variability within individual soils remains underexplored. Here we apply transmission electron microscopy (TEM) and atom probe tomography to four mineral grains (olivine, ilmenite, and two ...
