    Positive density dependence acting on mortality can help maintain species-rich communities

    Thomas G Aubier
    Some forms of positive density-dependence can favor species coexistence even if competitive species benefit the most from positive density-dependence.

    An ECF-type transporter scavenges heme to overcome iron-limitation in Staphylococcus lugdunensis

    Angelika Jochim, Lea Adolf ... Simon Heilbronner
    An ECF-type transporter serves as broad-spectrum heme iron scavenger and allows an opportunistic pathogen to use multiple eukaryotic hemoproteins to overcome nutritional iron-limitation.

    AMPAR/TARP stoichiometry differentially modulates channel properties

    Federico Miguez-Cabello, Nuria Sánchez-Fernández ... David Soto
    A variable number of auxiliary subunit molecules (TARPs) accompanying AMPARs have a differential impact on channel behavior showing also striking differences between AMPAR subtypes.

    Activity-dependent tuning of intrinsic excitability in mouse and human neurogliaform cells

    Ramesh Chittajallu, Kurt Auville ... Chris J McBain
    Similar to their mouse counterparts, human neurogliaform cells that comprise a specialized from of inhibitory neuron, possess the ability to modulate their intrinsic excitability in response to ongoing network activity.

    Genomic and phenotypic evolution of Escherichia coli in a novel citrate-only resource environment

    Zachary D Blount, Rohan Maddamsetti ... Richard E Lenski
    Transposable elements and gene amplifications can provide variation needed for novel trait refinement and adaptation to new niches, though a recalcitrant organism-environment mismatch may persist.
    1. Neuroscience

    The roles of online and offline replay in planning

    Eran Eldar, Gaëlle Lièvre ... Raymond J Dolan
    Replay of recently experienced trajectories during a decision task is coupled with more effective adaptation to change, whereas replay during rest is associated with limited decision making flexibility.

    MxB sensitivity of HIV-1 is determined by a highly variable and dynamic capsid surface

    Richard J Miles, Claire Kerridge ... Greg J Towers
    Conformational flexibility in HIV-1 capsid, provided by cyclophilin A binding, facilitates evasion of capsid-targeting restriction factor MxB, while allowing sequence change to facilitate cytotoxic T-cell evasion.
    1. Neuroscience

    Cell-type specific innervation of cortical pyramidal cells at their apical dendrites

    Ali Karimi, Jan Odenthal ... Moritz Helmstaedter
    The composition of inhibitory and excitatory synaptic inputs to the apical dendrites of pyramidal cells in mouse cortex is specific to the type of pyramidal cells.

    Hippocampal neural stem cells facilitate access from circulation via apical cytoplasmic processes

    Tamar Licht, Esther Sasson ... Eli Keshet
    Neural stem cells in the dentate gyrus have unique cytoplasmic processes that promote privileged access to circulating factors by a unique contact point with an endothelial cell.

    Tissue-resident macrophages promote extracellular matrix homeostasis in the mammary gland stroma of nulliparous mice

    Ying Wang, Thomas S Chaffee ... Kathryn L Schwertfeger
    A distinct resident macrophage subpopulation that localizes to the adipose stroma and fibrous capsule of the nulliparous mammary gland and to extracellular matrix-enriched stroma surrounding mammary tumors is identified.
