    Age-associated changes to neuronal dynamics involve a disruption of excitatory/inhibitory balance in C. elegans

    Gregory S Wirak, Jeremy Florman ... Christopher V Gabel
    Comprehensive multi-neuron fluorescence imaging in C. elegans reveals age-associated changes in neuronal activity that include a breakdown of system-wide organization, changes in neuronal frequency dynamics, and a disruption of the balance between excitatory and inhibitory signaling.

    Lipolysis of bone marrow adipocytes is required to fuel bone and the marrow niche during energy deficits

    Ziru Li, Emily Bowers ... Ormond A MacDougald
    Bone marrow adipocyte lipolysis is required for maintaining bone mass under conditions of energy deficiency and is necessary for myelopoiesis following caloric restriction and irradiation.

    Inferring characteristics of bacterial swimming in biofilm matrix from time-lapse confocal laser scanning microscopy

    Guillaume Ravel, Michel Bergmann ... Simon Labarthe
    A new mathematical method has been developed, implemented and validated for the analysis of time-lapse confocal laser scanning microscopy images to characterize the swimming behavior of bacterial swimmers moving in the exogenous matrix of pathogenic biofilms.

    The evolutionary history of human spindle genes includes back-and-forth gene flow with Neandertals

    Stéphane Peyrégne, Janet Kelso ... Svante Pääbo
    Analyses of spindle genes with missense changes in modern humans reveal evidence for positive selection since the split with archaic humans and show that modern humans interacted with Neandertals more than once in the past 200,000 years.

    Cancer type classification using plasma cell-free RNAs derived from human and microbes

    Shanwen Chen, Yunfan Jin ... Pengyuan Wang
    Both human and microbe cell-free RNA features in plasma could distinguish tumors of different primary locations.

    Niche-specific genome degradation and convergent evolution shaping Staphylococcus aureus adaptation during severe infections

    Stefano G Giulieri, Romain Guérillot ... Benjamin P Howden
    A large-scale analysis of Staphylococcus aureus within-host evolution based on a comprehensive catalogue of bacterial genetic variation reveals an excess of genome degradation signatures in infecting strains and new genetic loci of clinically relevant adaptation.

    Circadian programming of the ellipsoid body sleep homeostat in Drosophila

    Tomas Andreani, Clark Rosensweig ... Ravi Allada
    The circadian clock gates sleep drive by modulating sleep homeostat neurons.

    Metformin abrogates pathological TNF-α-producing B cells through mTOR-dependent metabolic reprogramming in polycystic ovary syndrome

    Na Xiao, Jie Wang ... Lamei Cheng
    Pathological TNF-α-producing B cells are involved in the pathological process of polycystic ovary syndrome, and metformin inhibits mTOR phosphorylation, affects metabolic reprogramming, and further inhibits TNF-α expression in pathological B cells.

    Antibacterial potency of type VI amidase effector toxins is dependent on substrate topology and cellular context

    Atanas Radkov, Anne L Sapiro ... Seemay Chou
    Distinct surfaces of an interbacterial competition cell wall toxin mediate interactions with different cellular binding partners, resulting in an inherent evolutionary trade-off across the toxin superfamily.

    Cre/lox regulated conditional rescue and inactivation with zebrafish UFlip alleles generated by CRISPR-Cas9 targeted integration

    Fang Liu, Sekhar Kambakam ... Maura McGrail
    A novel strategy to create genetic mosaics in zebrafish for cell type-specific analysis of gene function that can be applied to any gene of interest.
