Recent updates on the squid–vibrio symbiosis show mechanistic details that underlie the establishment and maintenance of a symbiotic association along the apical surfaces of an animal epithelium.
The rapid emergence of antibiotic resistance is recognized as a major public health threat. Nanomaterials have risen to tackle this problem through either improving the potency of existing antibiotics or generating entirely new antibacterial mechanisms.
Biofilms are a fundamental form of microbial life and occur in diverse environments, ranging from the mammalian gut to deep subsurface rocks. It is often claimed that most bacteria and archaea live in biofilms, but this claim awaits quantification. Recent updates on global microbial cell numbers prompt a revisiting of this question.
