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

iMetaOmics, EarlyView.
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.

Abell 1033: birth of a radio phoenix

, 2014
Extended steep-spectrum radio emission in a galaxy cluster is usually associated with a recent merger. However, given the complex scenario of galaxy cluster mergers, many of the discovered sources hardly fit into the strict boundaries of a precise ...

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)

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

iMetaOmics, EarlyView.
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.

A Physically Motivated Framework to Compare the Merger Timescales of Isolated Low- and High-mass Galaxy Pairs Across Cosmic Time

The Astrophysical Journal
The merger timescales of isolated low-mass pairs (10 ^8 < M _* < 5 × 10 ^9 M _⊙ ) on cosmologically motivated orbits have not yet been studied in detail, though isolated high-mass pairs (5 × 10 ^9 < M _* < 10 ^11 M _⊙ ) have been studied extensively.

Progress of metabolomics‐centric multi‐omics research in medicine

iMetaOmics, EarlyView.
The graphical abstract illustrates a holistic roadmap for metabolomics‐centric multi‐omics integration in medical research. The upper panel depicts the technological transition from traditional bulk analysis to high‐resolution single‐cell and spatial methodologies, specifically addressing inherent challenges such as molecular complexity and dynamic ...

The Neutral Hydrogen Kinematics of the Dwarf Galaxy Merger NGC 3239 [PDF]

, 2019
We present H I spectral line images of the nearby dwarf galaxy NGC 3239. The galaxy’s curious morphology suggests that it is a post-merger system. We propose that NGC 3239 is a merger because it has multiple tidal tails, an enhanced velocity dispersion ...

Gravitational Fragmentation in Galaxy Mergers: A Stability Criteria

, 2012
We study the gravitational stability of gaseous streams in the complex environment of a galaxy merger, because mergers are known to be places of ongoing massive cluster formation and bursts of star formation.

A Targeted Gamma-Ray Search of Five Prominent Galaxy Merger Systems with 17 years of Fermi-LAT Data

The Open Journal of Astrophysics
Galaxy mergers are among the most energetic astrophysical phenomena, driving intense star formation and potentially fueling cosmic ray acceleration, which can produce high energy $\gamma$-ray emission through hadronic processes.
