   Synchronization in renal microcirculation unveiled with high-resolution blood flow imaging

   Dmitry Postnov et al.

   High-resolution blood flow imaging confirms the presence of large, long-living synchronous clusters in renal microcirculation and reveals how vasoactive drugs affect synchronization properties.

   Zebrafish airinemes optimize their shape between ballistic and diffusive search

   Sohyeon Park et al.

   Mathematical characterization of the shape of cellular protrusions that form cell–cell contacts in tissues reveals the parameters required for optimizing biological functional objectives, like maximizing cell–cell contact and communicating directional information.

   A mechano-osmotic feedback couples cell volume to the rate of cell deformation

   Larisa Venkova et al.

   Whether deforming cells behave as elastic balls (deforming at constant volume) or as sponges (loosing volume as they deform) depends on how fast they change their shape, because the cell volume depends on the tension of the plasma membrane.

   Conformist social learning leads to self-organised prevention against adverse bias in risky decision making

   Wataru Toyokawa, Wolfgang Gaissmaier

   Mathematical modelling and large-scale online experiments revealed that learning from others can induce 'smarter' decisions even when most individuals are biased towards adverse risk aversion.

   Single-cell monitoring of dry mass and dry mass density reveals exocytosis of cellular dry contents in mitosis

   Teemu P Miettinen et al.

   A high-resolution approach for monitoring dry mass and the density of that dry mass on a single-cell level is developed and used to reveal that mammalian cells can lose components in mitosis due to lysosomal exocytosis.

   Coordination of two opposite flagella allows high-speed swimming and active turning of individual zoospores

   Quang D Tran et al.

   Coordinated actions of two opposite flagella control speed and change direction of plant pathogen Phytophthora zoospores, in which the anterior flagellum is the main motor to generate thrust and spontaneously switch from reciprocal beating to breaststrokes to reorient its body.

   Characterization of convergent thickening, a major convergence force producing morphogenic movement in amphibians

   David R Shook et al.

   Xenopus embryos use tissue surface tension to generate hoop-stress around the blastopore to help close it during gastrulation.

   Leading edge maintenance in migrating cells is an emergent property of branched actin network growth

   Rikki M Garner, Julie A Theriot

   Computational simulations of actin network growth at the cell leading edge, combined with careful high-speed video microscopy measurements of leading edge shape fluctuations, suggest that Arp2/3 branching of the actin network occurs at an optimal angle to minimize fluctuations.

    Unsupervised Bayesian Ising Approximation for decoding neural activity and other biological dictionaries

    Damián G Hernández et al.

    The proposed method deciphers which low-level patterns (such as spikes) control high-level features (behavior) in relative small biological datasets, taking into account the statistical dependencies between such patterns.
