    Genomic epidemiology of COVID-19 in care homes in the east of England

    William L Hamilton, Gerry Tonkin-Hill ... COVID-19 Genomics Consortium UK
    SARS-CoV-2 can spread efficiently within care homes causing outbreaks among residents, who are at increased risk of severe disease, emphasising the importance of stringent infection control in this population.

    Defective memory engram reactivation underlies impaired fear memory recall in Fragile X syndrome

    Jie Li, Rena Y Jiang ... Lu Chen
    Activity-dependent genetic labeling during behavioral learning shows Fragile-X syndrome model mice exhibit impaired hippocampal engram reactivation, and that enriched environment experience improves fear memory retrieval by enhancing engram reactivation efficacy.

    RNA polymerase errors cause splicing defects and can be regulated by differential expression of RNA polymerase subunits

    Lucas B Carey
    A single human cell makes 10-100 transcriptional errors per second; these errors affect splicing and may influence the evolution of coding sequences.

    Metapopulation ecology links antibiotic resistance, consumption, and patient transfers in a network of hospital wards

    Julie Teresa Shapiro, Gilles Leboucher ... Jean-Philippe Rasigade
    Patterns of antibiotic use and the connectivity between wards are independently associated with the incidence of antimicrobial-resistant infections in hospital networks.

    Improved clinical data imputation via classical and quantum determinantal point processes

    Skander Kazdaghli, Iordanis Kerenidis ... Philip Teare
    A new data imputation method that can be implemented quantumly allows for better and more reliable classifications.

    Structure and function of axo-axonic inhibition

    Casey M Schneider-Mizell, Agnes L Bodor ... Nuno Maçarico da Costa
    Electron microcopy-based connectomics, in vivo functional imaging, and biophysical modeling reveal that mouse visual cortex chandelier cells, a type of GABAergic interneuron, are driven by arousal and distribute their synapses according to the individual properties of target cells.

    HIV-1 DNA predicts disease progression and post-treatment virological control

    James P Williams, Jacob Hurst ... John Frater
    Measuring HIV-1 DNA levels at the time of stopping antiretroviral therapy (when initiated during primary infection) predicts clinical progression and the time taken for plasma viraemia to become detectable.

    Transmission dynamics and control of multidrug-resistant Klebsiella pneumoniae in neonates in a developing country

    Thomas Crellen, Paul Turner ... Ben S Cooper
    Colonisation with resistant Klebsiella pneumoniae in a Cambodian neonatal unit is driven by person-to-person transmission, transmissibility varies by sequence type, and antibiotic consumption generally increases the risk of acquisition.

    Demographic reconstruction from ancient DNA supports rapid extinction of the great auk

    Jessica E Thomas, Gary R Carvalho ... Michael Knapp
    Reconstruction of great auk population dynamics suggests that hunting pressure alone could have been responsible for their extinction, demonstrating that even abundant, widespread species can be vulnerable to intense exploitation.

    Eleven key measures for monitoring general practice clinical activity during COVID-19: A retrospective cohort study using 48 million adults’ primary care records in England through OpenSAFELY

    Louis Fisher, Helen J Curtis ... Ben Goldacre
    There was substantial change in primary care activity following the onset of the COVID-19 pandemic in March 2019 as indicated by key measures reflective of clinical activity in general practice but service was largely restored by April 2021.
