Locomotion and transport of microorganisms in fluids is an essential aspect of life. Search
for food, orientation toward light, spreading of off-spring, and the formation of colonies are …

In the past decade, the volvocine green algae, spanning from the unicellular
Chlamydomonas to multicellular Volvox, have emerged as model organisms for a number of …

Interactions between swimming cells and surfaces are essential to many microbiological
processes, from bacterial biofilm formation to human fertilization. However, despite their …

Flows generated by ensembles of flagella are crucial to development, motility and sensing,
but the mechanisms behind this striking coordination remain unclear. We present novel …

This work reviews the present position of and surveys future perspectives in the physics of
chaotic advection: the field that emerged three decades ago at the intersection of fluid …

From unicellular ciliates to the respiratory epithelium, carpets of cilia display metachronal
waves, long-wavelength phase modulations of the beating cycles, which theory suggests …

Groups of eukaryotic cilia and flagella are capable of coordinating their beating over large
scales, routinely exhibiting collective dynamics in the form of metachronal waves. The origin …

Rheotaxis, the directed response to fluid velocity gradients, has been shown to facilitate
stable upstream swimming of mammalian sperm cells along solid surfaces, suggesting a …

Inspired by the coordinated beating of the flagellar pair of the green algae Chlamydomonas,
we study theoretically a simple, mirror-symmetric swimmer, which propels itself at low …

The influence of hydrodynamic forces on eukaryotic flagella synchronization is investigated
by triggering phase locking between a controlled external flow and the flagella of C …
