    Multiple sources of slow activity fluctuations in a bacterial chemosensory network

    Remy Colin et al.
    Single-cell FRET measurements reveal large temporal activity fluctuations within this signaling pathway in Escherichia coli, caused by stochasticity of receptor methylation combined with allosteric interactions and slow rearrangements within receptor clusters.

    Physical limits to magnetogenetics

    Markus Meister
    Recent reports on the ability of biological molecules to sense magnetic fields are found to be inconsistent with basic physical principles.

    Flagellar energetics from high-resolution imaging of beating patterns in tethered mouse sperm

    Ashwin Nandagiri et al.
    Calculations of flagellar energetics from beating patterns in sperm reveal that internal dissipation by dynein motors and other passive structures within the flagellum significantly exceeds external hydrodynamic dissipation.

    Mechanisms of organelle biogenesis govern stochastic fluctuations in organelle abundance

    Shankar Mukherji, Erin K O'Shea
    A systematic comparison of experimentally measured and theoretically predicted magnitudes of organelle abundance fluctuations suggests that budding yeast produces the maximum level of variability in organelle abundance that can be generated by organelle biogenesis pathways.

    The axonal actin-spectrin lattice acts as a tension buffering shock absorber

    Sushil Dubey et al.
    A linear array of spectrin tetramers imparts mechanical stability to axons by allowing spectrin domains to unfold reversibly when an axon is stretched, thereby acting as tension buffers.

    Bridging the gap between single-cell migration and collective dynamics

    Florian Thüroff et al.
    A computational model, based on single-cell features like contractility and polarizability, quantitatively describes cellular dynamics from the single cell level up to small cohorts and confluent tissues.

    Spatiotemporal establishment of dense bacterial colonies growing on hard agar

    Mya R Warren et al.
    A 3D model captures the growth and expansion dynamics of bacterial colonies, revealing distinct effects of surface tension, mechanical forces, and nutrients on the speed of radial and vertical expansion.

    Evaluation of predictions of the stochastic model of organelle production based on exact distributions

    C Jeremy Craven
    A reanalysis of the stochastic model of organelle production (Mukherji and O'Shea, 2014) suggests that this model requires significant further discussion.

    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.

    Microbial consortia at steady supply

    Thibaud Taillefumier et al.
    In a consumer-resource model obeying the physical requirement of flux conservation, metabolic competition between microbes yields consortia of cell types that collectively resist invasion via optimal use of resources.
