    Length-dependent disassembly maintains four different flagellar lengths in Giardia

    Shane G McInally et al.
    Giardia, a multi-ciliated parasitic protist, maintains four different flagellar lengths by balancing flagellar length-independent IFT-mediated assembly with length-dependent kinesin-13 mediated disassembly.

    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.

    An integrin/MFG-E8 shuttle loads HIV-1 viral-like particles onto follicular dendritic cells in mouse lymph node

    Chung Park, John H Kehrl
    Intravital imaging with HIV-1 viral-like particle in mouse model reveals a mechanism for HIV-1 uptake by subcapsular sinus macrophages that facilitates HIV-1 spreading tofollicular dendritic and B cells.

    Interactions between Dpr11 and DIP-γ control selection of amacrine neurons in Drosophila color vision circuits

    Kaushiki P Menon et al.
    The survival of Drosophila amacrine neurons is controlled by neurotrophic signaling mediated by interactions between the cell surface protein DIP-γ and its partner Dpr11, which is expressed on presynaptic photoreceptors.

    A bidirectional network for appetite control in larval zebrafish

    Caroline Lei Wee et al.
    Brain imaging and behavioral analysis reveal two opposing states of hunger, represented by anti-correlated lateral and caudal hypothalamic dynamics that are important for the homeostatic control of feeding in zebrafish.

    Seminal fluid compromises visual perception in honeybee queens reducing their survival during additional mating flights

    Joanito Liberti et al.
    After insemination, honeybee queens experience a rapid reduction in vision and flight performance, consistent with an ongoing sexual conflict over the number of mating flights that queens embark on.

    Sleep-promoting effects of threonine link amino acid metabolism in Drosophila neuron to GABAergic control of sleep drive

    Yoonhee Ki, Chunghun Lim
    Threonine promotes sleep via down-regulation of metabotropic GABA transmission in the ellipsoid body R2 neurons that generate homeostatic sleep drive in Drosophila.

    Neurogenetic dissection of the Drosophila lateral horn reveals major outputs, diverse behavioural functions, and interactions with the mushroom body

    Michael-John Dolan et al.
    The generation and systematic characterisation of driver lines labelling a large number of neurons in the Drosophila innate olfactory processing centre bridges electron microscopy neuronal reconstructions, circuits and behaviour.

    Glial Ca2+signaling links endocytosis to K+ buffering around neuronal somas to regulate excitability

    Shirley Weiss et al.
    An unbiased genetic screen in Drosophila provides evidence for a direct link between glial Ca2+ 25 signaling and classical functions of glia in buffering external K+ as a mechanism to regulate neuronal excitability.

    Parallel visual circuitry in a basal chordate

    Matthew J Kourakis et al.
    The ascidian Ciona integrates visual information from two photoreceptor types through convergent excitatory and disinhibitory circuits, thereby evoking swim behaviors.
