A green-fluorescent siderophore protects bacterial communities from UV damage

The paper shows that pyoverdine, a siderophore produced by Pseudomonas aeruginosa, protects bacterial communities from UV damage by acting as a public sunscreen.

An intranasally administrated SARS-CoV-2 beta variant subunit booster vaccine prevents beta variant viral replication in rhesus macaques

An intranasal SARS-CoV-2 beta variant subunit booster vaccine induced protective immunity against beta variant infection in rhesus macaques one year after initial vaccination.

Siderophores drive invasion dynamics in bacterial communities through their dual role as public good versus public bad

The paper shows siderophores can either promote or hinder bacterial invasion depending on their dual role as public good or public bad.

Local adaptation, geographical distance and phylogenetic relatedness: assessing the drivers of siderophore-mediated social interactions in natural bacterial communities

The paper investigates factors driving siderophore-mediated social interactions in Pseudomonas communities, finding phylogenetic relatedness, not geographical distance, primarily determines cooperation and cheating behaviors.

Positive linkage between bacterial social traits reveals that homogeneous rather than specialized behavioral repertoires prevail in natural Pseudomonas communities

The paper examines trait linkage in natural Pseudomonas communities and finds that positive correlations between social traits are common, with most isolates showing a continuum of social behavior rather than specialized repertoires.

Environmental determinants of pyoverdine production, exploitation and competition in natural Pseudomonas communities

The paper investigates how environmental factors influence pyoverdine production and competition among Pseudomonas strains in natural communities.

The evolution of social life in family groups

This paper argues that current research on family life in animals is biased towards advanced social systems and neglects ancestral processes, hindering understanding of the evolution of social life.
