Multicellular and socially aggregating prokaryotes contain previously undescribed, chaperone-based systems predicted to mediate defensive biological conflicts, several components of which are thematically similar antecedents of eukaryotic apoptosis pathways.

Individual and situational differences in altruistic behavior do not reflect use of fundamentally different decision mechanisms, but instead differences in early perceptual or attentional processing of the choice-relevant information.

A new model describes evolutionary transitions in individuality in terms of tradeoff and tradeoff-breaking events as opposed to changes in the nature of fitness.

This review serves as a gateway to experimental, conceptual, and quantitative themes of cytoplasmic incompatibility (CI) and outlines significant gaps in the understanding of CI's mechanism that are ripe for investigation.

Arbitration is formalised as the relative precision of predictions afforded by reward and social learning systems and is represented in modality-specific dopaminergic and dopaminoceptive regions, including the midbrain and amygdala.

SUV39H1 histone methyltransferase directly binds chromosome associated RNA to promote constitutive heterochromatin formation.

Biochemical and structural analyses unravel how two RIG-I-like helicases function together to promote antiviral defense and illustrates the diverse ways innate immunity evolved.
