    STIL binding to Polo-box 3 of PLK4 regulates centriole duplication

    Christian Arquint et al.
    Binding of STIL to PLK4's characteristic Polo-box 3 links PLK4 kinase activation to STIL self-association and is a crucial regulatory step for the localized recruitment of downstream factors in centriole duplication.

    Rett-causing mutations reveal two domains critical for MeCP2 function and for toxicity in MECP2 duplication syndrome mice

    Laura Dean Heckman et al.
    Transgenic mice with Rett-causing mutations in MeCP2 reveal that a basic cluster in the C-terminus of the protein binds DNA and that both the methyl-CpG binding domain and the transcriptional repression domain are necessary to elicit toxicity in MECP2 duplication syndrome.

    Genome duplication in Leishmania major relies on persistent subtelomeric DNA replication

    Jeziel Dener Damasceno et al.
    Duplication of Leishmania chromosomes combines S-phase DNA replication initiated at a single internal region with subtelomeric DNA replication detectable outside S-phase, potentially explaining genome plasticity in this important parasite.

    The dimeric Golgi protein Gorab binds to Sas6 as a monomer to mediate centriole duplication

    Agnieszka Fatalska et al.
    The dual functional protein, Gorab, associates with the Golgi as a dimer but as a monomer with the procentriole cartwheel protein, Sas6, to mediate centriole duplication.

    The birth of a bacterial tRNA gene by large-scale, tandem duplication events

    Gökçe B Ayan et al.
    A bacterial tRNA gene set rapidly evolves, compensating the loss of one tRNA type by large duplication events that increase the gene copy number of a second, different tRNA type.

    Structured illumination with particle averaging reveals novel roles for yeast centrosome components during duplication

    Shannon Burns et al.
    Visualization of yeast spindle pole proteins using a new microscopy method shows that assembly into the nuclear membrane occurs at the same time as duplication.

    Centriolar satellites assemble centrosomal microcephaly proteins to recruit CDK2 and promote centriole duplication

    Andrew Kodani et al.
    To control centriole duplication, centriolar satellite proteins assemble a microcephaly-associated protein complex at the centrosome and activate cyclin-dependent kinase 2.

    Meta-analysis challenges a textbook example of status signalling and demonstrates publication bias

    Alfredo Sánchez-Tójar et al.
    Meta-analysis takes down a textbook example in behavioural and evolutionary ecology, and demonstrates the existence of biases in the current scientific publishing culture.

    Standardized mean differences cause funnel plot distortion in publication bias assessments

    Peter-Paul Zwetsloot et al.
    Funnel plots of the Standardized Mean Difference versus the standard error are prone to distortion, leading to false-positive tests for funnel plot asymmetry, and therefore using the Normalised Mean Difference, or a sample size-based precision estimate, are more reliable alternatives.

    Meta-Research: COVID-19 research risks ignoring important host genes due to pre-established research patterns

    Thomas Stoeger, Luís A Nunes Amaral
    An analysis of 10,395 research publications about COVID-19 that mention at least one human gene reveals that many genes implicated in SARS-CoV-2 infection by genome-wide studies remain unstudied.
