    Polygenic adaptation after a sudden change in environment

    Laura Katharine Hayward, Guy Sella
    A shift in fitness optimum of a polygenic trait rapidly introduces small frequency differences between alleles with effects aligned with and opposing the shift, which gradually translate into small differences in fixation probability.

    Cortex-wide response mode of VIP-expressing inhibitory neurons by reward and punishment

    Zoltán Szadai, Hyun-Jae Pi ... Balázs Rózsa
    VIP-expressing cortical interneurons represent organism-level information about reward and punishment for local microcircuits to regulate local processing and plasticity.

    Phenotyping single-cell motility in microfluidic confinement

    Samuel A Bentley, Hannah Laeverenz-Schlogelhofer ... Kirsty Y Wan
    A droplet microfluidics approach to stably trap and phenotype individual micron-sized algae reveals their distinct but stereotyped movement patterns and how they respond in real time to local environmental cues, including novel boundary circling behaviour under strong confinement.

    A general approach for stabilizing nanobodies for intracellular expression

    John G Dingus, Jonathan CY Tang ... Constance L Cepko
    A large proportion of nanobodies are unstable when expressed intracellularly, but can be reliably stabilized for intracellular expression by applying a generalizable mutagenesis strategy based on positional sequence conservation.

    Variation in the ACE2 receptor has limited utility for SARS-CoV-2 host prediction

    Nardus Mollentze, Deborah Keen ... Daniel G Streicker
    The success of angiotensin-converting enzyme 2 (ACE2)-based predictions of severe acute respiratory syndrome-associated virus 2 (SARS-CoV-2) host range stems from phylogenetic correlation, allowing development of scalable models which predict susceptibility to SARS-CoV-2 and other sarbecoviruses without requiring additional ACE2 sequencing.

    Transcriptome-wide association study and eQTL colocalization identify potentially causal genes responsible for human bone mineral density GWAS associations

    Basel Maher Al-Barghouthi, Will T Rosenow ... Charles R Farber
    Systems genetics approaches identify potentially causal bone mineral density genes.

    Instructions and experiential learning have similar impacts on pain and pain-related brain responses but produce dissociations in value-based reversal learning

    Lauren Y Atlas, Troy C Dildine ... Daniel S Pine
    Combining computational models with FMRI in humans during pain reversal learning reveals parallel pain modulatory brain circuits that differ in their flexibility and sensitivity to instructions.

    A connectomics-based taxonomy of mammals

    Laura E Suarez, Yossi Yovel ... Bratislav Misic
    Inter-species variations in connectome architecture across the mammalian phylogenetic spectrum recapitulate established taxonomic relationships defined by genetic, morphology, and behavioural differences, and are mainly driven by local changes in connectivity while hallmark global features tend to be conserved across species.

    Discrete GPCR-triggered endocytic modes enable β-arrestins to flexibly regulate cell signaling

    Benjamin Barsi-Rhyne, Aashish Manglik, Mark von Zastrow
    Two modes of GPCR endocytosis by β-arrestin are differentially coupled to downstream signaling.

    Mechanisms governing target search and binding dynamics of hypoxia-inducible factors

    Yu Chen, Claudia Cattoglio ... Xavier Darzacq
    Live-cell single particle tracking reveals the intrinsically disordered regions of transcription factors playing an unanticipated role in the nuclear search and chromatin binding process leading to functional target site selectivity and gene activation.
