Heterogeneous lineage-specific arginine deiminase expression within dental microbiome species

The paper investigates ADS operon expression in dental microbiomes using metatranscriptomics and identifies lineage-specific differences in ADS activity between healthy and cavitated teeth.

Intragroup sociality drives individual participation in intergroup competition in an urban-dwelling nonhuman primate

This study examines how socio-ecological factors influence participation in intergroup competition among urban-dwelling rhesus macaques, finding that affiliative connections and social position significantly affect engagement.

Histone Lactylation Drives CD8 T Cell Metabolism and Function

This study shows histone lactylation, specifically H3K18la and H3K9la, modulates CD8 T cell metabolism and function, impacting anti-tumor immunity.

Case report on lethal dog attacks on adult rhesus macaques (Macaca mulatta) in an anthropogenic landscape

The paper reports three cases of dog attacks on rhesus macaques in Northern India, highlighting the impact of domesticated dogs on primate populations and predator-prey dynamics in anthropogenic landscapes.

Ca2+/Calmodulin Dependent Protein Kinase Kinase-2 (CaMKK2) promotes Protein Kinase G (PKG)-dependent actin cytoskeletal assembly to increase tumor metastasis

This study identifies CaMKK2 as a driver of tumor metastasis through a novel signaling pathway involving PDE1A, PKG1, and VASP, suggesting it as a therapeutic target for TNBC and HGSOC.

Heart Rate n-Variability (HRnV) and Its Application to Risk Stratification of Chest Pain Patients in the Emergency Department

This study introduces HRnV, a new measure of heart rate variability, and shows it improves risk prediction for adverse cardiac events in chest pain ED patients compared to traditional scores.

Repurposing the Streptococcus mutans CRISPR-Cas9 System to Understand Essential Gene Function

The paper develops a CRISPR interference tool for Streptococcus mutans to study essential genes, identifying growth defects and phenotypes in 77% of targeted strains.

Exploring novel probiotic mechanisms of Streptococcus A12 with functional genomics

This study identifies molecular mechanisms by which Streptococcus A12 competes with S. mutans using functional genomics and gene deletion analysis.

Amino Sugars Modify Antagonistic Interactions between Commensal Oral Streptococci and Streptococcus mutans

This study shows amino sugars like GlcNAc and GlcN enhance the competitiveness of commensal oral streptococci against S. mutans, reducing its viability in co-cultures and biofilms.

Electron microscopy reveals unique spore-like nano forms of Bacillus cereus

The paper uses electron microscopy to identify nano-spore-like structures in Bacillus cereus under stress, showing they can bypass sterile filtration and transform into mature cells upon nutrient supply.

Species Designations Belie Phenotypic and Genotypic Heterogeneity in Oral Streptococci

The paper examines phenotypic and genotypic variability in oral Streptococcus isolates, finding poor correlation between genotype and phenotype across species.
