    Neural correlations enable invariant coding and perception of natural stimuli in weakly electric fish

    Michael G Metzen et al.
    Neural circuits in weakly electric fish perform a set of computations to allow natural communication signals to be perceived independently of their context.

    A multiplexed DNA FISH strategy for assessing genome architecture in Caenorhabditis elegans

    Brandon D Fields et al.
    The design and validation of an oligo-based DNA FISH library that targets the entire Caenorhabditis elegans genome at chromosome, three megabase, and 500 kb scales.

    Fish larval recruitment to reefs is a thyroid hormone-mediated metamorphosis sensitive to the pesticide chlorpyrifos

    Guillaume Holzer et al.
    Coral reef fish larval recruitment is a metamorphosis that can be disturbed by reef pollutants, as it is under the influence of the environment through the direct control of thyroid hormone signaling.

    Lateral interactions between protofilaments of the bacterial tubulin homolog FtsZ are essential for cell division

    Fenghui Guan et al.
    Structural and functional approaches unambiguously revealed physiologically relevant lateral interactions between FtsZ protofilaments.

    Peripheral sensory coding through oscillatory synchrony in weakly electric fish

    Christa A Baker et al.
    Sensory receptors encode stimuli by transiently synchronizing ongoing electrical oscillations, conferring enhanced sensitivity to communication signals produced by large groups of conspecifics.

    Architecture of the ring formed by the tubulin homologue FtsZ in bacterial cell division

    Piotr Szwedziak et al.
    The architecture of the bacterial cytokinetic ring in cells and in artificial liposome reconstitutions has been described using electron microscopy, leading to a mechanism of constriction.

    Detection of transient synchrony across oscillating receptors by the central electrosensory system of mormyrid fish

    Alejandro Vélez, Bruce A Carlson
    Building on previous work (Baker et al., 2015), further evidence is reported for a novel mechanism for sensory coding based on the detection of oscillatory synchrony among peripheral receptors.

    High-resolution mapping reveals hundreds of genetic incompatibilities in hybridizing fish species

    Molly Schumer et al.
    Genetic incompatibilities are common and widely distributed throughout the genomes of swordtail fish, and prevent the regions of the genome around them from being exchanged between different species.

    Stem cell topography splits growth and homeostatic functions in the fish gill

    Julian Stolper et al.
    The fish gill, an ever-growing organ with fast turnover rate, displays dedicated stem-cell populations for growth and homeostasis that are interchangeable upon external challenges.
