    Distinct roles for S. cerevisiae H2A copies in recombination and repeat stability, with a role for H2A.1 threonine 126

    Nealia CM House et al.
    Despite differing by only one amino acid in the C-terminal tail, copy 1 of yeast histone 2A has a repair-specific role not shared by copy 2.

    Deep sampling of Hawaiian Caenorhabditis elegans reveals high genetic diversity and admixture with global populations

    Tim A Crombie et al.
    Hawaiian Caenorhabditis elegans harbor high levels of genetic diversity that might represent the complex patterns of ancestral diversity in the species prior to human influence.

    Covalent linkage of the DNA repair template to the CRISPR-Cas9 nuclease enhances homology-directed repair

    Natasa Savic et al.
    Linking the DNA repair template to the Cas9 ribonucleoprotein complex enhances homology-directed repair of the induced DNA double strand break.

    The novel lncRNA lnc-NR2F1 is pro-neurogenic and mutated in human neurodevelopmental disorders

    Cheen Euong Ang et al.
    lnc-Nr2f1, a long non-coding RNA focally deleted in autism patients, directly occupies and regulates neuronal genes.

    Translational initiation in E. coli occurs at the correct sites genome-wide in the absence of mRNA-rRNA base-pairing

    Kazuki Saito et al.
    E. coli ribosomes incapable of base-pairing with the Shine-Dalgarno sequence are still selective for annotated start sites, indicating these sites are hard-wired for initiation by other mRNA features.

    Multi-protein bridging factor 1(Mbf1), Rps3 and Asc1 prevent stalled ribosomes from frameshifting

    Jiyu Wang et al.
    An eukaryotic specific system cooperates with the ribosome quality control pathway to maintain the reading frame during translation of slowly translated sequences.

    Genome-wide interrogation of extracellular vesicle biology using barcoded miRNAs

    Albert Lu et al.
    A screen using artificially barcoded, exosomal microRNAs, paired with CRISPR guide RNAs, helped identify new players in multivesicular endosome exocytosis and a role for Wnt signaling.

    A stochastic epigenetic switch controls the dynamics of T-cell lineage commitment

    Kenneth KH Ng et al.
    The timing and outcome of mammalian cell lineage decisions can be controlled by slow, stochastic events on individual regulatory gene loci.

    sRNA-mediated activation of gene expression by inhibition of 5'-3’ exonucleolytic mRNA degradation

    Sylvain Durand et al.
    Small regulatory RNAs are able to modulate mRNA degradation rates by controlling access to the 5' end of mRNAs in bacteria.

    Cell-wall remodeling drives engulfment during Bacillus subtilis sporulation

    Nikola Ojkic et al.
    Imaging experiments and simulations reveal that the biophysical mechanism for force generation needed to engulf a forespore is based on coordinated cell wall synthesis and degradation.
