    Distinct cytoskeletal proteins define zones of enhanced cell wall synthesis in Helicobacter pylori

    Jennifer A Taylor et al.
    The helical bacterium Helicobacter pylori patterns cell wall synthesis using two distinct cytoskeletal proteins, CcmA and MreB, to achieve its characteristic shape.

    C1 neurons are part of the circuitry that recruits active expiration in response to the activation of peripheral chemoreceptors

    Milene R Malheiros-Lima et al.
    An unbiased description reveals potential implications for understanding the developmental mechanisms that match respiratory supply and demand during hypoxia.

    From single neurons to behavior in the jellyfish Aurelia aurita

    Fabian Pallasdies et al.
    A multiscale computational nerve net model describes how the activity of individual neurons controls the swimming motion of a jellyfish in its hydrodynamic environment.

    Bridging the gap between single-cell migration and collective dynamics

    Florian Thüroff et al.
    A computational model, based on single-cell features like contractility and polarizability, quantitatively describes cellular dynamics from the single cell level up to small cohorts and confluent tissues.

    NINscope, a versatile miniscope for multi-region circuit investigations

    Andres de Groot et al.
    A light-weight, compact and open-source miniaturized fluorescence microscope integrates dual region brain imaging, optogenetic stimulation and behavioral parsing using an accelerometer.

    From behavior to circuit modeling of light-seeking navigation in zebrafish larvae

    Sophia Karpenko et al.
    Light-seeking strategies in Zebrafish larvae are dissected using a virtual-reality assay, and these data are used to establish minimal stochastic and neural-circuits models that quantitatively capture this behavior.

    Magnetic resonance measurements of cellular and sub-cellular membrane structures in live and fixed neural tissue

    Nathan H Williamson et al.
    Low-field single-sided magnetic resonance diffusion methods detect and measure permeability of sub-micron compartments which likely include cell processes, organelles, and cellular vesicles within ex vivo mouse spinal cords.

    Biochemical reconstitution of branching microtubule nucleation

    Raymundo Alfaro-Aco et al.
    The protein TPX2 and the protein complex augmin together recruit the microtubule nucleator γ-TuRC to a pre-existing microtubule where they initiate branching microtubule nucleation.

    Improved characterisation of MRSA transmission using within-host bacterial sequence diversity

    Matthew D Hall et al.
    Reconstruction of transmission pathways of methicillin-resistant Staphylococcus aureus using multiple genomes per host reveals great variation in the size of the transmission bottleneck and limited evidence for body site/phylogeny association.

    Asymmetric ON-OFF processing of visual motion cancels variability induced by the structure of natural scenes

    Juyue Chen et al.
    The fruit fly estimates visual motion by incorporating ON-OFF asymmetric processing that only improves performance when stimuli have light-dark asymmetries matched to natural scenes.
