    Repressive H3K9me2 protects lifespan against the transgenerational burden of COMPASS activity in C. elegans

    Teresa Wei-sy Lee, Heidi Shira David ... David John Katz
    The transgenerational inheritance of lifespan is facilitated by the accumulation of repressive chromatin across generations.

    Epigenetics: A memory of longevity

    Felicity Emerson, Cheng-Lin Li, Siu Sylvia Lee
    Worms with increased levels of the epigenetic mark H3K9me2 have a longer lifespan that can be passed down to future generations.

    Transcriptional adaptation in Caenorhabditis elegans

    Vahan Serobyan, Zacharias Kontarakis ... Didier YR Stainier
    Genes implicated in mutant mRNA decay and small RNA maturation and transport into the nucleus are required for transcriptional adaptation in C. elegans.

    Combinatorial chromatin dynamics foster accurate cardiopharyngeal fate choices

    Claudia Racioppi, Keira A Wiechecki, Lionel Christiaen
    ATAC-seq, CRISPR/Cas9 mutagenesis, reporter and gene expression assays revealed dynamic chromatin accessibility profiles governing differential gene expression during heart vs. pharyngeal muscle fate choices in the powerful chordate model Ciona.

    Single cell transcriptional signatures of the human placenta in term and preterm parturition

    Roger Pique-Regi, Roberto Romero ... Nardhy Gomez-Lopez
    Parturition gene regulation across multiple cell-types and placental compartments is deciphered at single cell resolution, highlighting the common role of the NFKB pathway in both term and preterm birth.

    A genome-wide view of the de-differentiation of central nervous system endothelial cells in culture

    Mark F Sabbagh, Jeremy Nathans
    In vitro culture of brain endothelial cells leads to a rapid loss of the blood-brain barrier transcriptional and accessible chromatin landscapes that is resistant to the effects of beta-catenin stabilization.

    Genealogy: The challenges of maintaining genetic privacy

    Shai Carmi
    Two studies suggest that a determined adversary may be able to obtain genetic information that they should not have permission to access from some genealogy databases.

    Mutations that improve efficiency of a weak-link enzyme are rare compared to adaptive mutations elsewhere in the genome

    Andrew B Morgenthaler, Wallis R Kinney ... Shelley D Copley
    Mutations elsewhere in the genome play critical roles in improving fitness during amplification and divergence of a gene encoding a weak-link enzyme whose inefficiency limits growth rate.

    Diversification of the Caenorhabditis heat shock response by Helitron transposable elements

    Jacob M Garrigues, Brian V Tsu ... Amy E Pasquinelli
    Helitron transposable elements, by providing high density transcription factor binding sites upstream of host genes, have diversified the heat shock response within and among Caenorhabditis species.

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

    Nealia CM House, Erica J Polleys ... Catherine H Freudenreich
    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.
