    Nuclear crowding and nonlinear diffusion during interkinetic nuclear migration in the zebrafish retina

    Afnan Azizi et al.
    The evolving spatial distribution of nuclei between apical and basal surfaces of the developing retinal neuroepithelium is quantitatively described by a nonlinear diffusion equation accounting for crowding within the tissue.

    Stoichiometric interactions explain spindle dynamics and scaling across 100 million years of nematode evolution

    Reza Farhadifar et al.
    Stoichiometric interactions between microtubules and cortical force-generators set spindle size, position and dynamics, and its scaling with cell size in nematode species.

    Size-dependent patterns of cell proliferation and migration in freely-expanding epithelia

    Matthew A Heinrich et al.
    Epithelia exhibit size-dependent growth dynamics caused by a decoupling between boundary and bulk cellular dynamics that enable robust expansion and drive cell cycling, collective migration, and tissue-spanning vortices.

    Efficient coding of natural scene statistics predicts discrimination thresholds for grayscale textures

    Tiberiu Tesileanu et al.
    An optimization principle allows natural-image data to predict human sensitivity to synthetic, un-natural textures with multiple gray levels.

    Social interactions drive efficient foraging and income equality in groups of fish

    Roy Harpaz, Elad Schneidman
    Analysis and modeling of group behavior of adult zebrafish shows that a specialized social interaction mechanism increases foraging efficiency and equality within groups, under a variety of environmental conditions.

    Nutrient levels and trade-offs control diversity in a serial dilution ecosystem

    Amir Erez et al.
    Whereas theories of ecological diversity mostly consider continuously supplied nutrients, a seasonal model uncovers a general mechanism that controls diversity and reconciles conflicting experimental findings.

    Dissecting the immunosuppressive tumor microenvironments in Glioblastoma-on-a-Chip for optimized PD-1 immunotherapy

    Xin Cui et al.
    A biomimetic and patient-specific Glioblastoma-on-a-Chip microphysiological system provides an avenue for personalized screening of PD-1 immunotherapy and novel combinational therapies that maximize therapeutic outcomes in Glioblastoma patients.

    Resource plasticity-driven carbon-nitrogen budgeting enables specialization and division of labor in a clonal community

    Sriram Varahan et al.
    Sufficient aspartate drives specialization within a microbial colony, when some cells use it to create a limited carbon-resource, while other cells consume this resource and use aspartate for nucleotide synthesis.

    Revealing architectural order with quantitative label-free imaging and deep learning

    Syuan-Ming Guo et al.
    Advances in quantitative phase and polarized light microscopy, combined with deep learning, reveal the architecture of human brain tissue.

    A mechanism for hunchback promoters to readout morphogenetic positional information in less than a minute

    Jonathan Desponds et al.
    Maternal positional information in the fly embryo can be read rapidly in spite of the gene-expression bottleneck and general examples of regulatory architectures that combine speed and accuracy are provided.
