    HIV-1 nuclear import in macrophages is regulated by CPSF6-capsid interactions at the nuclear pore complex

    David Alejandro Bejarano, Ke Peng ... Hans-Georg Kräusslich
    Interaction of HIV capsids with the cellular protein cleavage-and-polyadenylation factor 6 at the inner side of nuclear pores promotes nuclear entry of the viral replication complex in primary human macrophages.

    Brian 2, an intuitive and efficient neural simulator

    Marcel Stimberg, Romain Brette, Dan FM Goodman
    Brian 2 is a software package for neural simulations that makes it both easy and computationally efficient to define original models for computational experiment.

    An allosteric Sec61 inhibitor traps nascent transmembrane helices at the lateral gate

    Andrew L MacKinnon, Ville O Paavilainen ... Jack Taunton
    A small molecule, cotransin, blocks transmembrane domains form integrating into cell membranes by allosterically ‘locking’ the lateral gate of the Sec61 translocation channel.

    Quantitative microscopy of functional HIV post-entry complexes reveals association of replication with the viral capsid

    Ke Peng, Walter Muranyi ... Hans-Georg Kräusslich
    A robust method to quantitatively visualize HIV-1 replication complexes in infected cells shows that these complexes remain associated with the viral capsid beyond nuclear import in primary macrophages.

    A bend, flip and trap mechanism for transposon integration

    Elizabeth R Morris, Heather Grey ... Julia M Richardson
    Structural and biochemical analyses of a eukaryotic DNA transpososome in the integration step reveal how mariner/Tc1 transposons are selectively integrated into a TA target sequence.

    The laminar organization of the Drosophila ellipsoid body is semaphorin-dependent and prevents the formation of ectopic synaptic connections

    Xiaojun Xie, Masashi Tabuchi ... Alex L Kolodkin
    The organization of layered/laminated axon projections in specific regions of the fruitfly central brain is regulated by short-range repulsive guidance and is critical for local inhibitory circuit formation and function.

    Detecting changes in dynamic and complex acoustic environments

    Yves Boubenec, Jennifer Lawlor ... Bernhard Englitz
    Psychophysics experiments and EEG recordings reveal that people's performance in detecting unexpected changes in complex auditory scenes can be modeled as a process of sensory evidence accumulation.

    Pre-complexation of talin and vinculin without tension is required for efficient nascent adhesion maturation

    Sangyoon J Han, Evgenia V Azarova ... Gaudenz Danuser
    Pre-complexation of vinculin with talin’s R8 domain facilitates nascent adhesion maturation by unfolding talin, increasing vinculin binding, and thereby transmitting traction forces to the environment.

    Mechanism of completion of peptidyltransferase centre assembly in eukaryotes

    Vasileios Kargas, Pablo Castro-Hartmann ... Alan John Warren
    Cryo-EM reveals how the central functional site of the ribosome is assembled and provides a framework to interpret the consequences of mutations linked to leukaemia-associated ribosomopathies.

    Disintegration promotes protospacer integration by the Cas1-Cas2 complex

    Chien-Hui Ma, Kamyab Javanmardi ... Makkuni Jayaram
    Disintegration, regarded as an abortive side reaction antithetical to DNA transposition, can promote protospacer integration at the CRISPR locus via DNA repair pathways.
