Altered prefrontal late positive potential responses during neutral face processing are associated with negative interpretation bias in major depressive disorder

This study demonstrates that individuals with major depressive disorder exhibit altered prefrontal late positive potential responses during neutral face processing, which are significantly associated with negative interpretation bias and indirectly linked to reduced social competence.

Pseudomonas aeruginosa CntM-Dependent Upregulation of Staphylococcus aureus cntA Enhances Fitness During Co-Infection

This study reveals that during polymicrobial infection, *Pseudomonas aeruginosa* secretes the pseudopaline biosynthetic product CntM to upregulate *Staphylococcus aureus* metal acquisition gene *cntA*, thereby enhancing *S. aureus* fitness and tissue burdens in a co-infection environment.

Cultivation-dependent transcriptomic reprogramming and insecticidal performance of Beauveria bassiana A1 from solid-state and submerged cultures

This study demonstrates that while solid-state and submerged fermentation induce distinct transcriptomic reprogramming in *Beauveria bassiana* A1, particularly affecting secondary metabolism and extracellular degradation genes, both cultivation methods ultimately yield spores with comparable insecticidal efficacy against *Plutella xylostella* at high concentrations, supporting the potential of submerged fermentation as a scalable alternative for biopesticide production.

Transcutaneous auricular vagus nerve stimulation alleviates pain–depression comorbidity in mice through dorsal raphe–central amygdala serotonergic signaling

This study demonstrates that transcutaneous auricular vagus nerve stimulation (taVNS) alleviates pain-depression comorbidity in mice by activating a specific neural pathway where serotonergic neurons in the dorsal raphe nucleus project to the central amygdala, thereby restoring serotonin transmission and modulating 5-HT1A receptors to reverse both sensory hypersensitivity and depressive-like behaviors.

A C57BL/6NJ Congenic Background Delays Neurodegeneration, Gliosis and Synaptic Loss in the PS19 Tauopathy Model

This study demonstrates that placing the PS19 tauopathy mouse model on a metabolically intact C57BL/6NJ congenic background significantly delays the onset and progression of tau pathology, gliosis, and synaptic loss, thereby providing a more reliable model with greater temporal resolution for preclinical research.

SeAMT1;2a and SeAMT1;2b from the halophyte Salicornia europaea play dual roles in ammonium transport and salt tolerance

This study identifies and characterizes SeAMT1;2a and SeAMT1;2b as key ammonium transporters in the halophyte *Salicornia europaea* that not only facilitate efficient nitrogen uptake under saline conditions but also independently enhance salt tolerance, likely through potassium homeostasis, highlighting their potential for phytoremediation.

Rhizobacterial genetic diversity associated with Paspalum atratum and Paspalum notatum by metagenomic analysis

Metagenomic analysis of the rhizospheres of *Paspalum atratum* and *Paspalum notatum* reveals distinct, species-specific bacterial community compositions driven by soil pH, with *Acidobacteriaceae* dominating *P. atratum* and *Nitrosomonadaceae* characterizing *P. notatum*.
