    Emergence of a geometric pattern of cell fates from tissue-scale mechanics in the Drosophila eye

    Kevin D Gallagher, Madhav Mani, Richard W Carthew
    Formation of a triangular lattice of photoreceptor clusters in the compound eye is driven by highly regulated cell flows in the eye epithelium, through a mechanochemical mechanism.

    Cellular organization in lab-evolved and extant multicellular species obeys a maximum entropy law

    Thomas C Day, Stephanie S Höhn ... Peter J Yunker
    The distributions of cellular neighborhood volumes in two very different multicellular species - snowflake yeast and Volvox carteri - are found to obey a common functional form arising from maximum entropy consideration, despite great differences in their cell division processes.

    An empirical energy landscape reveals mechanism of proteasome in polypeptide translocation

    Rui Fang, Jason Hon ... Ying Lu
    Empirical energy landscape allows simulating the structural dynamics of the proteasomal ATPase complex, which yields predictions that are widely consistent with experimental observations and reveals the functional mechanism of the proteasome in substrate degradation.

    Correlative all-optical quantification of mass density and mechanics of subcellular compartments with fluorescence specificity

    Raimund Schlüßler, Kyoohyun Kim ... Jochen Guck
    The combination of optical diffraction tomography and Brillouin microscopy in a single setup enables to quantitatively map the viscoelastic properties of cellular compartments such as aggregates and stress granules in vivo.

    Volume growth in animal cells is cell cycle dependent and shows additive fluctuations

    Clotilde Cadart, Larisa Venkova ... Marco Cosentino Lagomarsino
    High-throughput measurement of single-cell volume reveals the short and large timescale fluctuation patterns of animal cell volume growth.

    Emergence of behaviour in a self-organized living matter network

    Philipp Fleig, Mirna Kramar ... Karen Alim
    Behavioural states emerge from variability in the complexity of underlying active contraction dynamics in a single-cell, network-shaped forager.

    A theory of synaptic transmission

    Bin Wang, Olga K Dudko
    The analytic theory establishes the general principles of synaptic transmission, enables extraction of microscopic parameters of synaptic fusion machinery from experiments, and links molecular constituents to synaptic function.

    Strong confinement of active microalgae leads to inversion of vortex flow and enhanced mixing

    Debasmita Mondal, Ameya G Prabhune ... Prerna Sharma
    Coupling between cell motility and strong confinement alters the force generators that cause flow fields to change their handedness and lead to enhanced mixing.

    Mechanism of life-long maintenance of neuron identity despite molecular fluctuations

    Joleen JH Traets, Servaas N van der Burght ... Jeroen S van Zon
    Differential binding kinetics of a master regulator to its target promoters can prevent spontaneous cell fate loss in a Caenorhabditis elegans neuron whose fate is controlled by a reversible switch.

    Antagonism between killer yeast strains as an experimental model for biological nucleation dynamics

    Andrea Giometto, David R Nelson, Andrew W Murray
    Like physical systems that exhibit nucleation phenomena, an invading population of a strong microbial antagonist requires a critical inoculum size to successfully invade a population of a weaker microbial antagonist.
