Genomic Characterisation of Poultry-Derived Enterococci in the Czech Republic: Insight into Virulence and Antimicrobial Resistance

This study characterizes 47 poultry-derived *Enterococcus* isolates from Czech farms using whole-genome sequencing and phenotypic testing, revealing a high prevalence of antimicrobial resistance and virulence genes—particularly in *E. faecalis*—and identifying three novel sequence types, thereby confirming poultry as a significant reservoir for these determinants.

(Un)predictable false memories: the role of sensorimotor language prediction in episodic memory

This study demonstrates that while semantically predictable words increase false memory regardless of motor similarity, encoding motor-similar but unpredictable action-object sentences through action observation enhances both accurate recall and metacognitive monitoring, highlighting the distinct roles of semantic and sensorimotor prediction in episodic memory.

Transcriptomic Insights into the Molecular Response of Stingless Bees (Tetragonula pagdeni) to Low-Temperature Stress

This study presents the first transcriptomic analysis of the stingless bee *Tetragonula pagdeni* under acute low-temperature stress, revealing significant differential expression in genes related to metabolic pathways, ribosome biogenesis, and xenobiotic detoxification that underpin its molecular cold tolerance mechanisms.

Endothelial RANK signaling triggers bone marrow inflammaging

This study identifies endothelial RANK signaling as a critical driver of bone marrow inflammaging by inducing IL-1β expression, which leads to senescent cell accumulation and hematopoietic dysfunction, thereby establishing it as a potential therapeutic target for age-related diseases.

CST1 stabilizes GPX4 to suppress ferroptosis and promote bladder cancer progression

This study demonstrates that CST1 promotes bladder cancer progression by binding to and stabilizing GPX4 through inhibition of its ubiquitin-dependent degradation, thereby suppressing ferroptosis.

Viscoelasticity and Interface Properties of Multi-Component Condensates Govern Protein Sequestration and Suppression of Amyloid Formation

Contrary to the prevailing view that stress granules act as crucibles for amyloid formation, this study demonstrates that multi-component biomolecular condensates robustly suppress fibril formation by sequestering proteins, constraining growth through viscoelasticity, and mitigating nucleation at interfaces.

Oral microbiota diversity and compositional shifts in relation to sleep quality: a cross-sectional study in Beijing adults

This cross-sectional study of Beijing adults reveals that poor sleep quality is associated with distinct oral microbiota signatures, including higher microbial diversity and specific taxonomic enrichments, suggesting a link between oral microbial composition and sleep status via the oral–gut–brain axis.

Plant nutrient status shapes predator and herbivore dynamics through plant-mediated pathways

This study demonstrates that nutrient enrichment shapes predator and herbivore dynamics not through a single pathway, but by simultaneously altering plant traits and prey availability, thereby creating complex, context-dependent interactions between the western flower thrips and the omnivorous predator *Orius insidiosus*.

Functional diversification of AA17 LPMOs reveals multiple polysaccharide-oxidising activities in plant-pathogenic oomycetes

This study reveals that the AA17 lytic polysaccharide monooxygenase family in oomycetes has functionally diversified beyond its known pectin-targeting role to include enzymes capable of oxidatively cleaving cellulose and xylan, with these expanded activities specifically evolving in plant-pathogenic lineages to target host cell wall components.

An intracellular auxin rheostat fine-tunes growth and wood patterning in poplar

This study reveals that the tonoplast-localized transporters WAT1 and WAT2 function as an intracellular auxin rheostat in poplar by dynamically regulating vacuolar sequestration of free auxin, a mechanism essential for fine-tuning cambial activity, wood patterning, and robust tree growth.
