    Pioneer neurog1 expressing cells ingress into the otic epithelium and instruct neuronal specification

    Esteban Hoijman et al.
    Quantitative 4D image analysis identifies a group of cells which enter into the otic primordium during morphogenesis and instructs neuronal specification.

    wtf genes are prolific dual poison-antidote meiotic drivers

    Nicole L Nuckolls et al.
    Selfish wtf meiotic drive genes use overlapping transcripts to encode both a trans-acting poison to kill gametes that do not inherit the gene and a gamete-autonomous antidote to specifically rescue the gametes that do.

    Molecular basis of outer kinetochore assembly on CENP-T

    Pim J Huis in 't Veld et al.
    The centromeric protein CENP-T assembles the microtubule-binding interface of kinetochores through direct recruitment of two Ndc80 complexes and indirect recruitment of a third one through the Mis12 complex.

    Integrated analysis of H2A.Z isoforms function reveals a complex interplay in gene regulation

    Assala Lamaa et al.
    The two H2A.Z isoforms have specific interactors which mediate their differential effects on gene expression.

    Transcriptional adaptation in Caenorhabditis elegans

    Vahan Serobyan et al.
    Genes implicated in mutant mRNA decay and small RNA maturation and transport into the nucleus are required for transcriptional adaptation in C. elegans.

    Ion counting demonstrates a high electrostatic field generated by the nucleosome

    Magdalena Gebala et al.
    First experimental studies on the ion atmosphere around a nucleosome provide a quantitative analysis of the molecule's electrostatic properties.

    Intrinsic cooperativity potentiates parallel cis-regulatory evolution

    Trevor R Sorrells et al.
    Cooperativity between two transcription regulators occurs through protein-protein interactions with a general transcription factor complex and potentiates the parallel evolution of their DNA binding sites.

    The splicing regulator PTBP2 controls a program of embryonic splicing required for neuronal maturation

    Qin Li et al.
    PTBP2 ensures that adult protein variants are expressed only in mature neurons through regulation of alternative splicing during early neuronal development.

    Clarinet (CLA-1), a novel active zone protein required for synaptic vesicle clustering and release

    Zhao Xuan et al.
    Clarinet, a novel C. elegans active zone protein with homology to vertebrate Piccolo and Rim, uses its different isoforms for diverse functions, including synaptic vesicle clustering, vesicle release and synaptogenesis.

    Initial elevations in glutamate and dopamine neurotransmission decline with age, as does exploratory behavior, in LRRK2 G2019S knock-in mice

    Mattia Volta et al.
    LRRK2 G2019S knock-in mice are a genetically faithful model that recapitulates the slow disease progression of familial PD, with initial alterations to behaviour and neurotransmission providing early pathophysiological targets for neuroprotective interventions.
