    Episode 26: December 2015

    In this episode we hear about heat-seeking behaviour in mosquitos, mass spawning in coral reefs, social organization in ants, fear in rats and tissue regeneration in newts.

    Episode 9: February 2014

    In this episode we learn more about sleep, super Spy chaperones, swimming bacteria, orphan genes and the neuroscience of birdsong.

    Acknowledging selection at sub-organismal levels resolves controversy on pro-cooperation mechanisms

    Wenying Shou
    Building on previous work (Momeni et al., 2013), it is shown that recognizing the hierarchical organization of biological systems resolves the ongoing controversy on pro-cooperation mechanisms.

    Feeding state-dependent regulation of developmental plasticity via CaMKI and neuroendocrine signaling

    Scott J Neal et al.
    CaMKI and neuroendocrine signaling integrate information about food status to regulate a developmental decision in C. elegans.
    1. Neuroscience

    The CNS connectome of a tadpole larva of Ciona intestinalis (L.) highlights sidedness in the brain of a chordate sibling

    Kerrianne Ryan et al.
    Serial-section EM analysis uncovers the CNS connectome of a Ciona larva, the second of any entire nervous system, and exposes left-right asymmetries in its synaptic circuits.

    Ankyrin-B is a PI3P effector that promotes polarized α5β1-integrin recycling via recruiting RabGAP1L to early endosomes

    Fangfei Qu et al.
    Ankyrin-B – through interactions with PI3P lipids, dynactin and RabGAP1L – functions as a critical node in the protein circuitry underlying polarized recycling of α5β1-integrin to enable haptotaxis along fibronectin gradients.

    Developmental programming modulates olfactory behavior in C. elegans via endogenous RNAi pathways

    Jennie R Sims et al.
    The OSM-9 TRPV channel is differentially regulated due to developmental programming via modulation by TGF-β signaling, endogenous RNAi and chromatin remodeling pathways.
    1. Neuroscience

    A serial multiplex immunogold labeling method for identifying peptidergic neurons in connectomes

    Réza Shahidi et al.
    A new technique called ‘siGOLD’ allows neural circuits to be mapped using a combination of antibody labeling and electron microscopy.
    1. Structural Biology and Molecular Biophysics

    Sequence co-evolution gives 3D contacts and structures of protein complexes

    Thomas A Hopf et al.
    Interactions in protein complexes can be predicted from evolutionary information from genomic sequences.

    Frazzled promotes growth cone attachment at the source of a Netrin gradient in the Drosophila visual system

    Orkun Akin, S Lawrence Zipursky
    Direct observation in the developing fly brain indicates that the response of a growth cone in a gradient of a guidance cue is adhesion to the source of the cue rather than attraction by the gradient.
