    Dnmt3a knockout in excitatory neurons impairs postnatal synapse maturation and increases the repressive histone modification H3K27me3

    Junhao Li, Antonio Pinto-Duarte ... M Margarita Behrens
    Loss of Dnmt3a in excitatory neurons disrupts synaptic morphology and behavior, and triggers the expansion of H3K27me3 binding, suggestive of increased polycomb repression.

    Dcp2 C-terminal cis-binding elements control selective targeting of the decapping enzyme by forming distinct decapping complexes

    Feng He, Chan Wu, Allan Jacobson
    Dcp2 C-terminal domain cis-regulatory elements collaborating with specific activators control decapping enzyme targeting and activation by orchestrating sequential assembly of distinct decapping complexes.

    Proximal CA1 20–40 Hz power dynamics reflect trial-specific information processing supporting nonspatial sequence memory

    Sandra Gattas, Gabriel A Elias ... Norbert J Fortin
    The hippocampal CA1 20–40 Hz rhythm is associated with nonspatial sequence memory processing and may contribute to the role of the hippocampus in processing temporal relationships among events.

    Palatal morphology predicts the paleobiology of early salamanders

    Jia Jia, Guangzhao Li, Ke-Qin Gao
    Salamanders originate as metamorphosed with a biphasic lifestyle as shown by the palate shape and several non-shape features associated with the vomerine teeth, with diverse ecological types displayed in living species achieved in the Early Cretaceous.

    Analysis of rod/cone gap junctions from the reconstruction of mouse photoreceptor terminals

    Munenori Ishibashi, Joyce Keung ... Stephen C Massey
    Each cone terminal is electrically coupled to around 50 nearby rods, forming a switchable circuit, known as the secondary rod pathway, in which all gap junction channels participate.

    Genome editing in the unicellular holozoan Capsaspora owczarzaki suggests a premetazoan role for the Hippo pathway in multicellular morphogenesis

    Jonathan E Phillips, Maribel Santos ... Duojia Pan
    Genome editing in a close unicellular relative of animals suggests a premetazoan function of the Hippo pathway effector YAP/TAZ/Yorkie in the regulation of cytoskeletal dynamics and multicellular morphogenesis but not proliferation.

    Distinct but overlapping roles of LRRTM1 and LRRTM2 in developing and mature hippocampal circuits

    Shreya H Dhume, Steven A Connor ... Tabrez J Siddiqui
    LRRTM1 and LRRTM2 play multifaceted roles in the molecular organization of neuronal circuits through mediating context-dependent functions in synapse development but independent roles in plasticity and cognition.

    Transposon mutagenesis in Mycobacterium abscessus identifies an essential penicillin-binding protein involved in septal peptidoglycan synthesis and antibiotic sensitivity

    Chidiebere Akusobi, Bouchra S Benghomari ... Eric J Rubin
    PBP-lipo is an essential cell-wall synthesis enzyme in Mycobacterium abscessus that localizes to the septum and whose expression is required for normal cell growth and division, as well as mediating sensitivity to several antibiotics including the β-lactams, ampicillin, and amoxicillin.

    A general decoding strategy explains the relationship between behavior and correlated variability

    Amy M Ni, Chengcheng Huang ... Marlene R Cohen
    The frequently observed relationship between perceptual performance and correlated variability in sensory cortex can be explained by observers using a decoding strategy that prioritizes generality for many stimuli over precision.

    Strength of interactions in the Notch gene regulatory network determines patterning and fate in the notochord

    Héctor Sánchez-Iranzo, Aliaksandr Halavatyi, Alba Diz-Muñoz
    Interaction strength in Notch signaling determines lateral inhibition patterning and drives fate in the unidimensional cell arrangement of the zebrafish notochord.
