    T cell self-reactivity during thymic development dictates the timing of positive selection

    Lydia K Lutes, Zoë Steier ... Ellen A Robey
    Developing T cells whose TCRs have relatively low reactivity experience very brief TCR signaling events, experience delayed positive selection, and retaina preselection gene expression signature as they mature.

    Variability in the Munc13-1 content of excitatory release sites

    Maria Rita Karlocai, Judit Heredi ... Zoltan Nusser
    Different numbers of Munc13-1 molecules build up the specialized regions of the presynaptic plasma membrane called the release sites.

    De novo macrocyclic peptides dissect energy coupling of a heterodimeric ABC transporter by multimode allosteric inhibition

    Erich Stefan, Richard Obexer ... Robert Tampé
    By random nonstandard peptide integrated discovery, combinatorial macrocyclic peptides were leavaged that target a heterodimeric ABC transport complex and explore fundamental principles of the substrate translocation cycle.

    Homoplasy in the evolution of modern human-like joint proportions in Australopithecus afarensis

    Anjali M Prabhat, Catherine K Miller ... Jeremy M DeSilva
    The human-like joint proportions of Australopithecus afarensis evolved independently, making 'Lucy' and her kind the earliest known evolutionary experiment in obligate bipedalism.

    Confinement discerns swarmers from planktonic bacteria

    Weijie Chen, Neha Mani ... Jay X Tang
    For the same bacterial strain, the swarming phenotype can be biophysically discerned from swimming phenotype based on the motion pattern under circular confinement on a soft agar.

    Compartment-specific opioid receptor signaling is selectively modulated by different dynorphin peptides

    Jennifer M Kunselman, Achla Gupta ... Manojkumar A Puthenveedu
    Different dynorphins, which signal similarly from the cell surface, can differentially localize G protein-coupled receptors to specific subcellular compartments and cause divergent receptor fates and distinct spatiotemporal patterns of signaling.

    Multiple decisions about one object involve parallel sensory acquisition but time-multiplexed evidence incorporation

    Yul HR Kang, Anne Löffler ... Michael N Shadlen
    When making two decisions about one object, two streams of information can be acquired in parallel but must be incorporated into the two decisions serially, consistent with a central bottleneck.

    The final step of 40S ribosomal subunit maturation is controlled by a dual key lock

    Laura Plassart, Ramtin Shayan ... Celia Plisson-Chastang
    Cryo-EM and functional studies reveal how combined action of proteins RPS26/eS26 and RIO1 allows late precursors to the human small ribosomal particle to be matured into fully translation-competent 40S subunits.

    Therapeutic inhibition of keratinocyte TRPV3 sensory channel by local anesthetic dyclonine

    Qiang Liu, Jin Wang ... Jing Yao
    Identifying and understanding that local anesthetic dyclonine targets TRPV3 channels will help to conceive therapeutic interventions.

    EXOC1 plays an integral role in spermatogonia pseudopod elongation and spermatocyte stable syncytium formation in mice

    Yuki Osawa, Kazuya Murata ... Fumihiro Sugiyama
    EXOC1 contributes to the proper differentiation balance of spermatogonial stem cells and spermatocyte syncytia formation by regulating the morphology of male germ cells.
