Hidden No More: Spotlight on Tidal Disruption Events in Active Galactic Nuclei

open access: yesAstronomische Nachrichten, Volume 347, Issue 5, June 2026.
ABSTRACT Tidal disruption events (TDEs) are typically discovered in previously quiescent galaxies. However, earlier studies have revealed a handful of TDEs occurring in pre‐existing active galactic nuclei (AGN). We discuss AT2019aalc, a promising TDE candidate in an AGN, and compare it to similar sources.

Subterranean environments contribute to three‐quarters of classified ecosystem services

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1582-1605, June 2026.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Phylogenetic and Environmental Insights Into the Biogeography of the Western Blacknose Dace, Rhinichthys obtusus

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Pleistocene glaciations have shaped freshwater fish evolution and distribution patterns across North America. This study investigated the phylogeographical history of the Western Blacknose Dace (Rhinichthys obtusus) using mitochondrial genomic data, revealing three major clades that diverged 2–1.5 million years ago during Pleistocene glaciations when ...

Arbuscular mycorrhizal fungal community abundance, functions, and symbiotic interactions revealed by root metatranscriptomes

open access: yesiMetaOmics, Volume 3, Issue 2, June 2026.
Paradigm shift: PCR‐free methods reveal 6–15‐fold higher arbuscular mycorrhizal (AM) fungal abundance than metabarcoding, exposing systematic underestimation across decades of research. Predictive power: AM fungal abundance serves as a community‐level trait that predicts crop yield under drought conditions.

Ginseng polysaccharides prevent mastitis through Lactobacillus murinus‐derived deoxycholic acid and TGR5 signaling

open access: yesiMetaOmics, Volume 3, Issue 2, June 2026.
Prebiotic Ginseng polysaccharides (GP) alleviate mastitis through selective enrichment of gut L. murinus, which elevates its anti‐inflammatory metabolite deoxycholic acid (DCA). Circulating DCA engages mammary epithelial TGR5 receptors, triggering the cAMP–PKA pathway to suppress NF‐κB/NLRP3‐mediated inflammation.
