MicrobiologyOpen, Volume 14, Issue 5, October 2025.An intact type 9 secretion system (T9SS) is required for Porphyromonas gingivalis‐mediated dysregulation of aortic smooth muscle cell migration and proliferation. During infection, T9SS also enhanced phosphorylation of multiple sites on transcription factor Smad3 that is implicated in pathologic cell responses to TGF‐β/Smad signaling.

Dynamically Driven Evolution of the Interstellar Medium in M51 [PDF]
, 2009 Massive star formation occurs in giant molecular clouds (GMCs); an understanding of the evolution of GMCs is a prerequisite to develop theories of star formation and galaxy evolution. We report the highest-fidelity observations of the grand-design spiral

The magnetic fields of large Virgo cluster spirals: Paper II [PDF]
, 2012 The Virgo cluster of galaxies provides excellent conditions for studying interactions of galaxies with the cluster environment. Both the high-velocity tidal interactions and effects of ram pressure stripping by the intracluster gas can be investigated in

A Chromosome Inversion Creates a Supergene for Sex and Colour in Lake Malawi Cichlids
Molecular Ecology, Volume 34, Issue 20, October 2025.ABSTRACT Cichlid fishes have the highest rates of evolutionary turnover of sex chromosomes among vertebrates. Many large structural polymorphisms in the radiation of cichlids in Lake Malawi are associated with sex chromosomes and may also carry adaptive variation.

Brain and Behavior, Volume 15, Issue 8, August 2025.How do we accurately measure mind wandering? This review compares five methods: from self‐reports (prone to bias) to brain scans (precise but expensive). No single method captures all aspects, so we propose the MAMW framework—a unified approach combining strengths of each technique.

Gas and Stellar Motions and Observational Signatures of Co-Rotating Spiral Arms [PDF]
, 2014 We have observed a snapshot of our N-body/Smoothed Particle Hydrodynamics simulation of a Milky Way-sized barred spiral galaxy in a similar way to how we can observe the Milky Way. The simulated galaxy shows a co-rotating spiral arm, i.e.

ChemCatChem, Volume 17, Issue 15, August 7, 2025.An enzyme that has been identified and characterized as capable of hydrolyzing paclitaxel (Taxol), a key anticancer drug derived from Pacific yew (Taxus brevifolia) has been identified. Molecular docking (MD) simulations map the catalytic triad and critical residues that drive substrate‐enzyme interactions. The findings indicate the catalytic potential

On the chains of star complexes and superclouds in spiral arms
, 2010 The relation is studied between occurrence of a regular chain of star complexes and superclouds in a spiral arm, and other properties of the latter. A regular string of star complexes is located in the north-western arm of M31; they have about the same ...
