    Multiple inputs ensure yeast cell size homeostasis during cell cycle progression

    Cecilia Garmendia-Torres, Olivier Tassy ... Gilles Charvin
    Yeast cell size homeostasis is not controlled by a G1-specific mechanism alone but is likely to be an emergent property resulting from the integration of several mechanisms that coordinate cell and bud growth with division.

    A quantitative approach for analyzing the spatio-temporal distribution of 3D intracellular events in fluorescence microscopy

    Thierry Pécot, Liu Zengzhen ... Charles Kervrann
    QuantEv is a fully automatic and semi-parametric method that allows quantitative analysis of the spatio-temporal distribution of complex molecular trafficking objects at the scale of the whole cell.

    Highly multiplexed immunofluorescence imaging of human tissues and tumors using t-CyCIF and conventional optical microscopes

    Jia-Ren Lin, Benjamin Izar ... Peter K Sorger
    t-CyCIF can be used to collect spatially-encoded, multiparametric data from fixed and embedded research or clinical specimens making it possible to probe the organization of tumors and tissues at a single-cell level.

    A positive-feedback-based mechanism for constriction rate acceleration during cytokinesis in Caenorhabditis elegans

    Renat N Khaliullin, Rebecca A Green ... Karen Oegema
    Positive feedback between contractile ring myosin and compression-driven cortical flow can explain the exponential accumulation of contractile ring components and constriction rate acceleration that ensures timely cell separation during cytokinesis.

    Biophysical clocks face a trade-off between internal and external noise resistance

    Weerapat Pittayakanchit, Zhiyue Lu ... Arvind Murugan
    Molecular clocks that are robust to external fluctuations are vulnerable to internal fluctuations and vice versa.

    Vertex sliding drives intercalation by radial coupling of adhesion and actomyosin networks during Drosophila germband extension

    Timothy E Vanderleest, Celia M Smits ... Dinah Loerke
    Tricellular vertices possess sliding behaviors that harness radial forces and drive cell shape changes and intercalation in an epithelial tissue.

    Removing physiological motion from intravital and clinical functional imaging data

    Sean C Warren, Max Nobis ... Paul Timpson
    Image-based motion correction enables the use of fluorescence lifetime and other functional imaging modalities in an intravital and clinical context in the presence of physiological motion.

    TASEP modelling provides a parsimonious explanation for the ability of a single uORF to derepress translation during the integrated stress response

    Dmitry E Andreev, Maxim Arnold ... Pavel V Baranov
    A model reveals how translation of an mRNA leader could provide resistance to global downregulation of translation.

    The eukaryotic bell-shaped temporal rate of DNA replication origin firing emanates from a balance between origin activation and passivation

    Jean-Michel Arbona, Arach Goldar ... Benjamin Audit
    The universal eukaryotic DNA replication kinetics is the consequence of simple physicochemical rules resulting from the localisation of potential replication origins at discrete sites and the diffusion of limiting origin firing factors in the nuclear space.
