    Bi-channel image registration and deep-learning segmentation (BIRDS) for efficient, versatile 3D mapping of mouse brain

    Xuechun Wang et al.
    A dual-channel image registration pipeline combined with deep-learning inference achieves accurate-and-flexible registration/segmentation/mapping of mouse brain.

    Systematic identification of cis-regulatory variants that cause gene expression differences in a yeast cross

    Kaushik Renganaath et al.
    Yeast promoters can harbor multiple natural DNA variants that influence gene expression, interact genetically, evolve under negative selection, alter transcription factor motifs, and remain challenging to predict.

    Sequential activation of transcriptional repressors promotes progenitor commitment by silencing stem cell identity genes

    Noemi Rives-Quinto et al.
    Silencing of stem cell identity genes during progenitor commitment ensures that intermediate progenitors robustly commit to generate differentiated cell types rather than abnormal stem-cell-like cells during indirect neurogenesis.

    Genome-wide CRISPR screen identifies noncanonical NF-κB signaling as a regulator of density-dependent proliferation

    Maria Fomicheva, Ian G Macara
    TRAF3, a negative regulator of noncanonical NF-κB signaling, maintains epithelial cell quiescence at confluence, and its loss triggers upregulation of immunity genes and prevents entry into G0 at high cell density.

    Transport mechanism of P4 ATPase phosphatidylcholine flippases

    Lin Bai et al.
    A detailed molecular mechanism on lipid flipping from outside leaflet to the inside leaflet of the eukaryotic plasma membrane bilayer.

    New capsaicin analogs as molecular rulers to define the permissive conformation of the mouse TRPV1 ligand-binding pocket

    Simon Vu et al.
    Novel capsaicin analogs with conserved chemistry but varying sizes were used as molecular rulers to investigate energetics of conformational changes in the ligand-binding pocket and mechanisms of TRPV1 ligand-gating.

    Does diversity beget diversity in microbiomes?

    Naïma Madi et al.
    Microbiomediversity favors further diversity in a positive feedback that is strongest in lower-diversity biomes but which plateaus as niches are increasingly filled in higher-diversity biomes.

    The palmitoyl acyltransferase ZDHHC14 controls Kv1-family potassium channel clustering at the axon initial segment

    Shaun S Sanders et al.
    ZDHHC14 controls palmitoylation and axon initial segment targeting of PSD93 and Kv1-family potassium channels, events that are essential for normal neuronal excitability.

    A stepped-wedge randomised trial on the impact of early ART initiation on HIV-patients’ economic outcomes in Eswatini

    Janina Isabel Steinert et al.
    A stepped-wedge randomised controlled trial shows that early antiretroviral therapy (ART) initiation does not negatively affect the economic welfare of HIV patients in a low-income country.
