Silent Spread: Olfactory Bulb α-Synuclein Seeding in Wild-Type Mice Drives Pathology and Transient Neuroinflammation While Sparing Function

This study demonstrates that while bilateral olfactory bulb injection of α-Synuclein preformed fibrils in wild-type mice induces widespread, persistent pathology and transient neuroinflammation within the olfactory network, it fails to trigger olfactory dysfunction, nigrostriatal degeneration, or motor impairments, revealing a significant disconnect between α-Syn accumulation and functional Parkinsonian phenotypes.

Spatial O-GalNAc glycoproteomics atlas: region-specific regulation across the mouse brain

This study introduces a novel DIA-centric workflow (Glyco-DIA 2.0) to generate the first region-resolved quantitative atlas of O-GalNAc glycosylation across nine mouse brain compartments, revealing site-specific regulatory patterns on key neuronal proteins and providing an interactive public resource to explore this spatial layer of brain molecular architecture.

A One Health analysis of the Human Gut Resistome across 34 countries in relation to climate, geography, diet, and veterinary antimicrobial use

This study analyzes the gut resistomes of young adults from 34 countries to reveal that while the overall burden of antimicrobial resistance is primarily driven by temperature, the specific composition of resistance genes is shaped by continental location, dietary patterns, and veterinary antibiotic use, highlighting the need for region-specific stewardship strategies.

Chloroplast genomes of Vanilla spp. (Orchidaceae) provide new evolutionary insights into the genus

This study sequenced and analyzed 17 complete chloroplast genomes of *Vanilla* species to identify highly variable molecular markers and genes under positive selection, thereby confirming the genus's monophyly and providing critical genomic resources for its phylogenetic, taxonomic, and conservation research.

The predictive power of new remote sensing data for biological distributions

This study demonstrates that integrating novel remote sensing data, such as GEDI LiDAR-derived canopy height and hyperspectral foliar traits, significantly enhances the accuracy and interpretability of models predicting bird vocal activity across California's Sierra Nevada by capturing nuanced, species-specific habitat requirements.

Within-patient vastus lateralis median frequency asymmetry during isokinetic exercise after ACL reconstruction: a cross-sectional secondary analysis

This cross-sectional secondary analysis reveals that while sample entropy did not differentiate groups, median frequency asymmetry in the vastus lateralis muscle persists in the involved limb of ACL-reconstructed patients compared to healthy controls during isokinetic exercise, suggesting it could complement traditional torque-based assessments.
