    A switch in surface polymer biogenesis triggers growth-phase-dependent and antibiotic-induced bacteriolysis

    Josué Flores-Kim et al.
    Penicillin induces bacterial cell lysis by altering cell surface polymer biogenesis to cause the misactivation of a cell wall degrading enzyme.

    Highly regulated, diversifying NTP-dependent biological conflict systems with implications for the emergence of multicellularity

    Gurmeet Kaur et al.
    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.

    Transient inflammatory response mediated by interleukin-1β is required for proper regeneration in zebrafish fin fold

    Tomoya Hasegawa et al.
    The Interleukin 1 beta signaling and tissue inflammation act as a double-edged sword: they are required for regeneration, but when in excess, they impair tissue regeneration and induce apoptosis.
