The actomyosin cytoskeleton generates active chiral torques that lead to left-right asymmetry in C. elegans embryos.

Zebrafish have a physiological time-window of 1 hr for breaking left-right symmetry and are highly sensitive to the left-right organizer anterior fluid mechanics rather than to the nature of its fluid content.

Using a combination of all-atom molecular simulation and continuum membrane mechanics, M2 channels from influenza are shown to be stabilized in negative Gaussian curvature regions, such as the neck of budding viral particles, only in C2-symmetric conformations.

Spontaneous elongation of epithelial colonies is related to the orientation of the mean nematic cell elongation field, as shown and tested with experiments and theory.

Novel mechanisms for cellular centering and symmetry breaking involving persistent contractile actomyosin flows and their hydrodynamic interactions with the fluid cytosol are presented and studied using a minimal, reconstituted system.

Confidence-dependent reinforcement learning is active and produces trial-to-trial choice updating even in well-learned perceptual decisions without explicit reward biases, across species and sensory modalities.

Seemingly disparate property-based tasks (oddball search, same-different and symmetry) are solved by computing a novel image property, visual homogeneity, which is localized to the object selective cortex.

External hydrodynamic forcing on each flagellum of Chlamydomonas reinhardtii reveals a leader-follower relation between the two flagella in the synchronous beating.

Large-scale in vivo imaging of the zebrafish left-right organizer (Kupffer's vesicle) combined with fluid dynamics calculations allows to quantitatively test the possible flow detection mechanisms and supports the flow transport of chemical signals as the mechanism of side determination.

A computational framework enables the inference of hydrodynamic continuum models for collective cell migration from live-cell imaging data recorded in zebrafish embryos.
