    Transcription-associated topoisomerase 2α (TOP2A) activity is a major effector of cytotoxicity induced by G-quadruplex ligands

    Madeleine Bossaert, Angélique Pipier ... Dennis Gomez
    Topoisomerase 2α DNA breaks induced by G-quadruplex ligands are associated with a topological stress resulting from a transcription-dependent mechanism and counteracted by DNA topoisomerase 1 and factors promoting transcription elongation.

    Cavin3 released from caveolae interacts with BRCA1 to regulate the cellular stress response

    Kerrie-Ann McMahon, David A Stroud ... Robert G Parton
    Cavin3 associates with BRCA1 upon disassembly of caveolae in response to mechanical and non-mechanical stressors to influence DNA repair and apoptosis.

    Loss of Tsc1 in cerebellar Purkinje cells induces transcriptional and translation changes in FMRP target transcripts

    Jasbir Singh Dalal, Kellen Diamond Winden ... Mustafa Sahin
    Tsc1 mutation in cerebellar Purkinje cells leads to downregulation of synapse genes that are targets of the Fragile X Mental Retardation Protein.

    Relationship between changing malaria burden and low birth weight in sub-Saharan Africa: A difference-in-differences study via a pair-of-pairs approach

    Siyu Heng, Wendy P O'Meara ... Dylan S Small
    A novel pair-of-pairs matching approach finds that community-level reductions in malaria burden can potentially substantially reduce the low birth weight rate in sub-Saharan Africa, particularly among firstborns.

    Mechanistic theory predicts the effects of temperature and humidity on inactivation of SARS-CoV-2 and other enveloped viruses

    Dylan H Morris, Kwe Claude Yinda ... James O Lloyd-Smith
    Viruses, including SARS-CoV-2, retain infectivity longer at low temperatures and extreme relative humidities because these conditions slow down the chemical reactions that inactivate those viruses.

    Specialized coding patterns among dorsomedial prefrontal neuronal ensembles predict conditioned reward seeking

    Roger I Grant, Elizabeth M Doncheck ... James M Otis
    Excitatory output neurons in dorsomedial prefrontal cortex display heterogeneously specialized coding properties that evolve during cue-reward learning and predict cue-driven reward seeking.

    Neural correlates of ingroup bias for prosociality in rats

    Inbal Ben-Ami Bartal, Jocelyn M Breton ... Daniela Kaufer
    A distinct neural network, including the nucleus accumbens as a central hub, is active when rats are exposed to trapped ingroup members they had previously helped escape a trap, but not for outgroup members who had not been helped.

    Lives saved with vaccination for 10 pathogens across 112 countries in a pre-COVID-19 world

    Jaspreet Toor, Susy Echeverria-Londono ... Katy AM Gaythorpe
    Vaccination activities that occurred before the COVID-19 pandemic, 2000-2019, are estimated to avert 50 million deaths, highlighting the enormous benefits of continued and improving vaccination.
