    Promiscuous binding by Hsp70 results in conformational heterogeneity and fuzzy chaperone-substrate ensembles

    Rina Rosenzweig et al.
    Multiple chaperone binding sites on substrates suggest a mechanism by which the Hsp70 chaperone can circumvent kinetic traps in protein folding.

    Conserved conformational selection mechanism of Hsp70 chaperone-substrate interactions

    Ashok Sekhar et al.
    NMR-based flux measurements show that both bacterial and human Hsp70 chaperones interact with helical, as well as sheet substrates predominantly through a conformational selection mechanism.

    Interspecies interactions induce exploratory motility in Pseudomonas aeruginosa

    Dominique H Limoli et al.
    Pseudomonas aeruginosa coordinates invasion and destruction of Staphylococcus aureus communities by modulating single-cell and collective motility.

    Transcriptional profiling reveals extraordinary diversity among skeletal muscle tissues

    Erin E Terry et al.
    There is no such thing as a representative skeletal muscle tissue, as each member of this family of tissues expresses a specialized mRNA program.

    Listeria monocytogenes cell-to-cell spread in epithelia is heterogeneous and dominated by rare pioneer bacteria

    Fabian E Ortega et al.
    The pathogenic bacterium Listeria monocytogenes spreads infection using a two-tiered strategy, where most bacteria spread locally but a few 'pioneers' move further, increasing the likelihood of a persistent infection.

    A broadly distributed toxin family mediates contact-dependent antagonism between gram-positive bacteria

    John C Whitney et al.
    Diverse LXG toxins delivered by the Esx pathway function as mediators of contact-dependent interbacterial antagonism within and between Gram-positive bacterial species.

    Downsizing the molecular spring of the giant protein titin reveals that skeletal muscle titin determines passive stiffness and drives longitudinal hypertrophy

    Ambjorn Brynnel et al.
    Genetically altering the size of the molecular spring element in the giant protein titin established that titin determines the stiffness of skeletal muscle and the number of sarcomeres in series.

    Bacterial flagellar capping proteins adopt diverse oligomeric states

    Sandra Postel et al.
    The first high-resolution structure of a bacterial flagellar cap protein, FliD, reveals new insights into the assembly of bacterial flagella.

    Kin cell lysis is a danger signal that activates antibacterial pathways of Pseudomonas aeruginosa

    Michele LeRoux et al.
    The death of bacterial kin cells releases a danger signal that activates a posttranscriptional response in surviving cells, resulting in the rapid elaboration of interbacterial competition factors.
