Ontogenetic changes in body size are weakly associated with basal metabolic rate in a maternity colony of Myotis velifer

This study reveals that while body mass scales positively with basal metabolic rate in *Myotis velifer*, individual variation in metabolic rate is only weakly explained by body size, age, or reproductive status, suggesting that other intrinsic and ecological factors drive energy expenditure within maternity colonies.

The brain-meningeal interface functions as a reservoir and entry site for brain parenchymal macrophages

This study challenges the dogma of microglia exclusivity by demonstrating that the brain-meningeal interface serves as a reservoir and entry site for peripheral macrophages, which can differentiate and migrate into the brain parenchyma to repopulate vacated niches, particularly in aging and neurodegenerative conditions.

Shadows of Consciousness: An Investigation into Ionic Neural Networks Using the Neurotransmitter Ion Receptor Glial Endocannabinoid Network (NIRGEN) Paradigm

This paper critiques the historical and political delays in updating AI architectures to reflect biological reality, arguing that the field's reliance on continuous voltage abstractions ignores critical ionic, glial, and retrograde mechanisms, and consequently proposes NIRGEN, a discrete, biophysically grounded Ionic Neural Network that overcomes the limitations of standard models by incorporating molecular conservation laws and enabling computations like XOR with single units.

Piezo1-Mediated Mechanotransduction Drives Blood–Spinal Cord Barrier Disruption and Neuroinflammation in Lumbar Spinal Stenosis-Induced Neuropathic Pain

This study demonstrates that in lumbar spinal stenosis, mechanical stress activates the Piezo1 ion channel to disrupt the blood–spinal cord barrier and trigger neuroinflammation via the FAK/RhoA/ROCK and CaMKII/NF-κB pathways, thereby driving neuropathic pain that can be alleviated by Piezo1 inhibition.

Network Topology Defines Therapeutic Vulnerability and Resistance in FLT3-Mutant Acute Myeloid Leukemia

This study demonstrates that the clinical behavior, therapeutic response, and resistance mechanisms in FLT3-mutant acute myeloid leukemia are determined by the topological architecture of gene interaction networks rather than individual mutations, with modular networks correlating to favorable outcomes and redundant, rewired networks driving resistance and relapse.

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.
