    Evolutionary stability of collateral sensitivity to antibiotics in the model pathogen Pseudomonas aeruginosa

    Camilo Barbosa et al.
    Evolutionary trade-offs enhance efficacy of antibiotic therapy by constraining bacterial adaptation in dependence of drug order and trade-off effect size.

    Protein polyglutamylation catalyzed by the bacterial calmodulin-dependent pseudokinase SidJ

    Alan Sulpizio et al.
    The pseudokinase-like Legionella effector SidJ catalyzes the glutamylation of bacterial ubiquitin ligases in a calmodulin-dependent manner.

    A unicellular relative of animals generates a layer of polarized cells by actomyosin-dependent cellularization

    Omaya Dudin et al.
    Cellularization in Sphaeroforma arctica generates a self-organized structure that morphologically resembles an epithelium, and is associated with tightly regulated expression of cell adhesion pathways.

    Cocaine-induced endocannabinoid signaling mediated by sigma-1 receptors and extracellular vesicle secretion

    Yoki Nakamura et al.
    Non-synaptic extracellular vesicles may be involved in the release of endogenous cannabinoids in the central nervous system thereby representing a novel mechanism to mediate their effects on synaptic transmission.

    Adaptation to mutational inactivation of an essential gene converges to an accessible suboptimal fitness peak

    João V Rodrigues, Eugene I Shakhnovich
    When an essential metabolic gene in E. coli is mutationally inactivated, subsequent evolution rarely reverts the mutation to wild type but rather follows unexpected paths that rewire metabolic fluxes.

    Experimental investigation of ant traffic under crowded conditions

    Laure-Anne Poissonnier et al.
    Behavioral experiments reveal that ants, contrary to humans, avoid the formation of traffic jams at extreme density.

    Interplay of disordered and ordered regions of a human small heat shock protein yields an ensemble of ‘quasi-ordered’ states

    Amanda F Clouser et al.
    Multiple iso-energetic-specific interactions involving the intrinsically-disordered region of sHSP HSPB1 define a quasi-ordered state, providing insights into inherited disease-associated mutations within the region that are thought to be disordered.

    Pretectal neurons control hunting behaviour

    Paride Antinucci et al.
    A discrete population of genetically accessible pretectal neurons controls visually guided hunting behaviour in larval zebrafish.

    Evolutionary emergence of Hairless as a novel component of the Notch signaling pathway

    Steven W Miller et al.
    Hairless emerged as an evolutionarily novel regulatory protein that replaced an ancestral paradigm of direct co-repressor recruitment by Suppressor of Hairless, its partner transcription factor in the Notch signaling pathway.

    Evolution of Yin and Yang isoforms of a chromatin remodeling subunit precedes the creation of two genes

    Wen Xu et al.
    Gene sharing through different isoforms can precede the formation of independent genes.
