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.
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.
Visualized odor encounters show that Drosophila navigate spatiotemporally complex odor plumes using random walks biased by the timing of brief and unpredictable odor encounters.

A combination of massively parallel reporter assays and mass spectrometry uncovers the regulation of previously unexplored promoters across the Escherichia coli genome.
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.
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 between microtubules and cortical force-generators set spindle size, position and dynamics, and its scaling with cell size in nematode species.

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.
