Capsular polysaccharides of Acinetobacter baumannii regulate type VI secretion system activity, balancing self-protection with interbacterial competitiveness.

The detection of low quantities of alkaloids in putatively nontoxic species of poison frogs sheds light on early evolutionary stages of chemical defense in animals.

Bacterial location quantifications highlights how Drosophila melanogaster larvae discriminate bacteria to isolate and later eliminate pathogens in the anterior midgut through coordinated mechanisms involving reactive oxygen species (ROS) and antimicrobial peptides (AMPs).

Genetically diverse rats reveal a single underlying construct linking key addiction-like behaviors, challenging compulsivity as an independent measure, and offering a new perspective on vulnerability and resilience to addiction.
