    Changes in ferrous iron and glutathione promote ferroptosis and frailty in aging Caenorhabditis elegans

    Nicole L Jenkins et al.
    As worms age reduced glutathione together with increased ferrous iron increases frailty and leads to ferroptosis, which is amenable to therapeutic intervention.

    Molecular determinants of large cargo transport into the nucleus

    Giulia Paci et al.
    Efficient nuclear transport of very large biomolecules, relevant for viral transport, scales non-linearly with size and its kinetics can be explained by a simple two-parameter energetic model.

    Tetramerisation of the CRISPR ring nuclease Crn3/Csx3 facilitates cyclic oligoadenylate cleavage

    Januka S Athukoralage et al.
    A widespread ribonuclease is a CRISPR-associated ring nuclease with a highly unusual cooperative mechanism involving tetramerisation of the enzyme.

    The histone modification reader ZCWPW1 links histone methylation to PRDM9-induced double-strand break repair

    Tao Huang et al.
    ZCWPW1 is a histone modification reader that localizes to DMC1-labelled double-strand break hotspots in a largely PRDM9-dependent manner, where it facilitates completion of synapsis by mediating DSB repair process.

    Screening of healthcare workers for SARS-CoV-2 highlights the role of asymptomatic carriage in COVID-19 transmission

    Lucy Rivett et al.
    3% of >1,000 asymptomatic healthcare workers in their workplace tested positive for SARS-CoV-2, suggesting that comprehensive screening programmes are vital to prevent acquisition of COVID-19 in hospitals.

    mRNA stem-loops can pause the ribosome by hindering A-site tRNA binding

    Chen Bao et al.
    By sterically hindering tRNA binding and inhibiting translation elongation, mRNA stem-loops can modulate gene expression.

    A non-canonical role for the EDC4 decapping factor in regulating MARF1-mediated mRNA decay

    William R Brothers et al.
    Crosslink immunopreciptiation (iCLIP) studies reveal important mechanistic insights into how MARF1 post-transcriptionally regulates targeted mRNAs and uncover a novel mode by which EDC4 regulates mRNA metabolism.

    Enhancement of homology-directed repair with chromatin donor templates in cells

    Grisel Cruz-Becerra, James T Kadonaga
    Precise genome editing by homology-directed repair occurs more efficiently with a chromatin donor template than with a naked DNA donor template.

    Cryo-EM structure in situ reveals a molecular switch that safeguards virus against genome loss

    Oliver W Bayfield et al.
    Structure of the portal protein of a thermostable virus, determined in its capsid-bound state, reveals a molecular mechanism that prevents DNA slippage during genome packaging.

    Science Forum: SARS-CoV-2 (COVID-19) by the numbers

    Yinon M Bar-On et al.
    Key numbers about the biology of the SARS-CoV-2 virus and the infection of a single human host by the virus have been compiled from the peer-reviewed literature.
