    Aerotaxis in the closest relatives of animals

    Julius B Kirkegaard et al.
    The colony-forming choanoflagellate Salpingoeca rosetta is capable of moving towards oxygen using logarithmic sensing of oxygen concentrations and a navigation strategy that involves random movements.

    Rapid changes in tissue mechanics regulate cell behaviour in the developing embryonic brain

    Amelia J Thompson et al.
    During embryonic development, tissue stiffness, which provides an important signal to motile cells, changes locally within tens of minutes in a well-controlled manner.

    Changes to social feeding behaviors are not sufficient for fitness gains of the Caenorhabditis elegans N2 reference strain

    Yuehui Zhao et al.
    Use of experimental manipulation demonstrates that social/solitary feeding behaviors are unrelated to the fitness gains conferred by causative alleles in two previously identified genes.

    Shared behavioral mechanisms underlie C. elegans aggregation and swarming

    Siyu Serena Ding et al.
    Two seemingly distinct behaviors in social C. elegans worms, namely aggregating into groups and swarming over food, are driven by the same underlying mechanisms.

    Hypoxia-inducible factor cell non-autonomously regulates C. elegans stress responses and behavior via a nuclear receptor

    Corinne L Pender, H Robert Horvitz
    The hypoxia-inducible factor HIF drives transcription of the gene cyp-36A1, which encodes a cytochrome P450 enzyme that acts via a putative intercellular signal to regulate the nuclear receptor NHR-46 and consequently stress resistance and behavior.

    Sexually dimorphic control of gene expression in sensory neurons regulates decision-making behavior in C. elegans

    Zoë A Hilbert, Dennis H Kim
    A sexually dimorphic transcriptional switch in sensory neurons integrates information about microbial environment and nutritional state to regulate exploratory behavior in C. elegans..

    Magnetosensitive neurons mediate geomagnetic orientation in Caenorhabditis elegans

    Andrés Vidal-Gadea et al.
    With the aid of a pair of sensory neurons, the nematode worm C. elegans is able to detect the Earth's magnetic field and use it to navigate towards food sources.

    Regulation of two motor patterns enables the gradual adjustment of locomotion strategy in Caenorhabditis elegans

    Ingrid Hums et al.
    Peptidergic neurons regulate undulation and turning movements to enable Caenorhabditis elegans to gradually adjust its locomotion strategy from dispersal to local search.

    The p38 MAP kinase pathway modulates the hypoxia response and glutamate receptor trafficking in aging neurons

    Eun Chan Park, Christopher Rongo
    The subcellular localization of the prolyl hydroxylase oxygen sensor in C. elegans neurons is regulated by p38 MAP kinase signaling.

    Paxillin facilitates timely neurite initiation on soft-substrate environments by interacting with the endocytic machinery

    Ting-Ya Chang et al.
    Hippocampal neurons undergo bi-stable behavior as neurites emerge, and the dominance of either state is determined by environmental mechanical properties and paxillin-associated cellular endocytic activities.
