    Efficient mate finding in planktonic copepods swimming in turbulence

    François-Gaël Michalec, Itzhak Fouxon ... Markus Holzner
    Calanoid copepods achieve efficient mate finding in turbulence through active swimming and turbulence advection, indicating that reproduction is not restricted to spatial and temporal windows of calm hydrodynamic conditions.

    Diffusion vs. direct transport in the precision of morphogen readout

    Sean Fancher, Andrew Mugler
    A theory predicts whether diffusion or direct transport establishes a more precise morphogen profile, and this prediction explains data from a wide variety of morphogens in two different organisms.

    Walking Drosophila navigate complex plumes using stochastic decisions biased by the timing of odor encounters

    Mahmut Demir, Nirag Kadakia ... Thierry Emonet
    Visualized odor encounters show that Drosophila navigate spatiotemporally complex odor plumes using random walks biased by the timing of brief and unpredictable odor encounters.

    Olfactory Navigation: Tempo is the key

    Antonio Celani
    Walking flies find the source of attractive odors by changing how frequently they stop and turn in response to the smell.

    Label-free imaging of immune cell dynamics in the living retina using adaptive optics

    Aby Joseph, Colin J Chu ... Jesse Schallek
    Immune cell motility and vascular response are imaged in vivo and label free in the CNS for the first time, using high-resolution phase-contrast adaptive optics retinal imaging.

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

    Afnan Azizi, Anne Herrmann ... William A Harris
    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, Che-Hang Yu ... Daniel J Needleman
    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, Ricard Alert ... Daniel J Cohen
    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, Mary M Conte ... Vijay Balasubramanian
    An optimization principle allows natural-image data to predict human sensitivity to synthetic, un-natural textures with multiple gray levels.
