    Lowland plant arrival in alpine ecosystems facilitates a decrease in soil carbon content under experimental climate warming

    Tom WN Walker, Konstantin Gavazov ... Jake M Alexander
    Uphill migrations of lowland plants into warming alpine ecosystems may yield a positive climate feedback by accelerating soil microbial respiration and decreasing soil carbon content.
    1. Neuroscience

    The presynaptic ribbon maintains vesicle populations at the hair cell afferent fiber synapse

    Lars Becker, Michael E Schnee ... Anthony J Ricci
    The auditory hair cell synaptic ribbon maintains vesicle pools near release sites in order to support sustained and timed vesicle release.

    Mapping nonlinear receptive field structure in primate retina at single cone resolution

    Jeremy Freeman, Greg D Field ... EJ Chichilnisky
    Multi-electrode recordings and modeling are combined to reveal the transformations of signals from cones to bipolar cells and then to ganglion cells within the primate retina.

    Analysis of rod/cone gap junctions from the reconstruction of mouse photoreceptor terminals

    Munenori Ishibashi, Joyce Keung ... Stephen C Massey
    Each cone terminal is electrically coupled to around 50 nearby rods, forming a switchable circuit, known as the secondary rod pathway, in which all gap junction channels participate.

    Energy coupling and stoichiometry of Zn2+/H+ antiport by the prokaryotic cation diffusion facilitator YiiP

    Adel Hussein, Shujie Fan ... David L Stokes
    Cryo-EM, Molecular Dynamics, and in vitro binding assays are combined to elucidate a new occluded conformation associated with zinc binding and energy coupling with the proton motive force.

    Entorhinal-retrosplenial circuits for allocentric-egocentric transformation of boundary coding

    Joeri BG van Wijngaarden, Susanne S Babl, Hiroshi T Ito
    An extended border coding circuit across the entorhinal and retrosplenial cortex incorporates self-referenced and viewpoint-invariant boundary information to guide navigation behavior.

    3D cell neighbour dynamics in growing pseudostratified epithelia

    Harold Fernando Gómez, Mathilde Sabine Dumond ... Dagmar Iber
    The 3D shape and dynamic organization of epithelial cells are far more complex than previously believed, but can be explained with simple physical principles based on lateral surface energy minimisation.

    The axonal actin-spectrin lattice acts as a tension buffering shock absorber

    Sushil Dubey, Nishita Bhembre ... Pramod Pullarkat
    A linear array of spectrin tetramers imparts mechanical stability to axons by allowing spectrin domains to unfold reversibly when an axon is stretched, thereby acting as tension buffers.
