A Critical Call for Mechanistic Investigations of Metal‐Bacteria Interactions

Advanced Materials, EarlyView.
It is well established that the antibacterial properties of metals have tremendous importance for bioengineering applications. What is not as appreciated, however, is the reproducibility crisis in this field's vast literature. In this perspective, we highlight this reproducibility problem, discuss its sources, and suggest solutions towards focused ...

Host norepinephrine biases codon-dependent virulence translation in EHEC

mSystems
Bacterial pathogens sense host-derived signals to control virulence, yet how these cues shape translation remains unclear. McShane et al. show that the host hormone norepinephrine rewires the tRNA epitranscriptome of enterohemorrhagic Escherichia coli ...

GaSex Nanoparticles Modulate Neutrophil Function and Mitigate NET‐Driven Osteogenic Impairment in Osteomyelitis Therapy

Advanced Materials, EarlyView.
Neutrophil extracellular traps (NETs) emerge as a critical repair‐limiting factor in osteomyelitis, driving osteoblast mitochondrial dysfunction and excessive PINK1/Parkin‐mediated mitophagy. Gallium–selenium nanoparticles (GaSex) scavenge reactive oxygen species, redirect neutrophils from NETosis toward bactericidal phagocytosis, eliminate methicillin‐
