    Major satellite repeat RNA stabilize heterochromatin retention of Suv39h enzymes by RNA-nucleosome association and RNA:DNA hybrid formation

    Oscar Velazquez Camacho et al.
    An RNA-mediated mechanism that stabilizes association of the Suv39h enzymes at mouse heterochromatin is defined.

    Dynamic turnover of centromeres drives karyotype evolution in Drosophila

    Ryan Bracewell et al.
    De novo formation of centromeres creates diverse karyotypes in flies and is accompanied by rapid turnover of centromere-associated satellite repeats.

    Recurring patterns in bacterioplankton dynamics during coastal spring algae blooms

    Hanno Teeling et al.
    Dynamic successive blooms of clades of planktonic marine bacteria that can be observed during blooms of marine algae follow discernible patterns, part of which might be explained by substrate-induced forcing.

    A novel class of inferior colliculus principal neurons labeled in vasoactive intestinal peptide-Cre mice

    David Goyer et al.
    VIP neurons are a novel class of inferior colliculus stellate neurons that project to long-range auditory and non-auditory targets and integrate inputs from the auditory brainstem and contralateral IC.

    Coalescing beneficial host and deleterious antiparasitic actions as an antischistosomal strategy

    John D Chan et al.
    Engagement of both host and parasite signaling pathways proves a novel approach for developing improved anti-parasitic therapies.

    Functional properties of stellate cells in medial entorhinal cortex layer II

    David C Rowland et al.
    Stellate cells in the medial entorhinal cortex are functionally heterogeneous but a substantial fraction are grid cells.

    Transgenerational dynamics of rDNA copy number in Drosophila male germline stem cells

    Kevin L Lu et al.
    rDNA copy number is shown to dynamically change during aging and through generations, and is actively maintained in male germline of Drosophila.

    Short-term plasticity at cerebellar granule cell to molecular layer interneuron synapses expands information processing

    Kevin Dorgans et al.
    Molecular, structural and functional diversity of cerebellar granule cell inputs on single molecular layer interneurons extends information processing in feed-forward inhibition microcircuits.

    Noise promotes independent control of gamma oscillations and grid firing within recurrent attractor networks

    Lukas Solanka et al.
    Random fluctuations in neuronal firing may enable a single brain region, the medial entorhinal cortex, to perform distinct roles in cognition (by generating gamma waves) and spatial navigation (by producing a grid cell map).

    Microtubule plus-ends act as physical signaling hubs to activate RhoA during cytokinesis

    Vikash Verma, Thomas J Maresca
    MT plus-end-mediated recruitment of a cortical pool of ECT2 trigger RhoA activation upon contact, which results in localized contractility during cytokinesis.
