    Prefrontal cortex state representations shape human credit assignment

    Amrita Lamba, Matthew R Nassar, Oriel FeldmanHall
    The medial prefrontal cortex and orbitofrontal cortex work in concert to match state representations from feedback to those at choice, and the strength of these common neural codes predict credit assignment precision.

    Complex subsets but redundant clonality after B cells egress from spontaneous germinal centers

    Carlos Castrillon, Lea Simoni ... Michael C Carroll
    In an autoimmune environment B cells mature from spontaneous germinal centers into transcriptomically and phenotypically diverse memory and antibody-secreting cells but maintaining shared clonal and potential self-reactive specificities which has important implications for pathogenic cell targeted depletion.

    The Drosophila Nab2 RNA binding protein inhibits m6A methylation and male-specific splicing of Sex lethal transcript in female neuronal tissue

    Binta Jalloh, Carly L Lancaster ... Ken Moberg
    The disease-associated RNA binding protein Nab2 is required to inhibit m6A RNA methylation in female Drosophila neuronal tissue and controls key splicing events such as sex-specific splicing of the Sex-lethal RNA.

    Spatial structure favors microbial coexistence except when slower mediator diffusion weakens interactions

    Alexander Lobanov, Samantha Dyckman ... Babak Momeni
    Investigating microbial communities in a spatial environment in silico suggests that spatial structure promotes higher coexistence by allowing spatial self-organization, but can hinder coexistence by weakening interactions mediated through diffusible metabolites.

    Kinetochore-fiber lengths are maintained locally but coordinated globally by poles in the mammalian spindle

    Manuela Richter, Lila Neahring ... Sophie Dumont
    Live imaging and physical perturbations of spindles with unfocused poles reveal that mammalian spindle length emerges locally from kinetochore-fibers, but that global cues from focused spindle poles are needed to coordinate k-fibers across space and time and accurately segregate chromosomes.

    Combined lineage tracing and scRNA-seq reveals unexpected first heart field predominance of human iPSC differentiation

    Francisco X Galdos, Carissa Lee ... Sean M Wu
    TBX5 lineage tracing and high resolution single cell transcriptomics uncover the predominance of first heart field development during human-induced pluripotent stem cell cardiac differentiation.

    Structural insights into regulation of CNNM-TRPM7 divalent cation uptake by the small GTPase ARL15

    Luba Mahbub, Guennadi Kozlov ... Kalle Gehring
    ADP-ribosylation factor-like GTPase 15, an atypical small GTPase, binds to cystathionine-β-synthase-pair domain divalent metal cation transport mediator (CNNM) membrane proteins to inhibit divalent cation efflux by CNNM proteins and influx by transient receptor potential ion channel subfamily M member 7.

    Widespread mermithid nematode parasitism of Cretaceous insects

    Cihang Luo, George O Poinar ... Bo Wang
    Sixteen new mermithid nematodes associated with their insect hosts are discovered from mid-Cretaceous Kachin amber and they are more abundant in non-holometabolous insect hosts, revealing what appears to be a vanished history of nematodes parasitism.

    Low-level repressive histone marks fine-tune gene transcription in neural stem cells

    Arjun Rajan, Lucas Anhezini ... Cheng-Yu Lee
    Stem-cell-specific transcriptional repressors fine-tune levels of stemness gene transcripts in asymmetrically dividing neural stem cells by depositing low levels of repressive histone marks at these loci allowing progeny to rapidly initiate differentiation.

    Rapid, automated, and experimenter-free touchscreen testing reveals reciprocal interactions between cognitive flexibility and activity-based anorexia in female rats

    Kaixin Huang, Laura K Milton ... Claire J Foldi
    An automated touchscreen cognitive testing system for rats reduces the length of training required to learn tasks, making it possible to assess cognitive profiles in adolescent animals to more appropriately capture cognitive deficits in adolescent pathologies, such as anorexia nervosa.
