    Extracellular matrix in multicellular aggregates acts as a pressure sensor controlling cell proliferation and motility

    Monika E Dolega et al.
    Theoretical predictions and experiments on multicellular aggregates indicate that the extracellular matrix acts as a mechanical sensor, which regulates cell proliferation and migration in a three-dimensional environment.

    Ligand sensing enhances bacterial flagellar motor output via stator recruitment

    Farha Naaz et al.
    Sensing of ligands by chemoreceptors of Escherichia coli not only causes changes in the rotational bias of the flagellar motors but also increases motor speed via temporary recruitment of stators.

    Global epistasis emerges from a generic model of a complex trait

    Gautam Reddy, Michael M Desai
    Predictable patterns of fitness evolution observed in microbial evolution experiments can emerge generically as a consequence of widespread epistatic interactions between mutations.

    Topological signatures in regulatory network enable phenotypic heterogeneity in small cell lung cancer

    Lakshya Chauhan et al.
    Network topology and gene expression patterns in small cell lung cancer reveal two mutually opposing teams of regulators that enable multistability and consequent non-genetic heterogeneity, a clinically unsolved challenge.

    From local resynchronization to global pattern recovery in the zebrafish segmentation clock

    Koichiro Uriu et al.
    Theory explains how transport of gene expression vortices by cell advection may cause intermingled defective and normal segments along the body axis during resynchronization experiments in the zebrafish segmentation clock.

    Bulk flow of cerebrospinal fluid observed in periarterial spaces is not an artifact of injection

    Aditya Raghunandan et al.
    A new tracer infusion method is used to confirm that pulsatile cerebrospinal fluid transport into the brain occurs naturally and is driven by the cardiac cycle, not by tracer injection.

    Decoding the physical principles of two-component biomolecular phase separation

    Yaojun Zhang et al.
    Phase separation of two-component multivalent systems is suppressed at rational polymer stoichiometries, suggesting possible cellular strategies for regulating the formation and function of biomolecular condensates.
