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 …

Bacteria predate plants and animals by billions of years. Today, they are the world's smallest
cells, yet they represent the bulk of the world's biomass and the main reservoir of nutrients …

Fluid dynamics plays a crucial role in many cellular processes, including the locomotion of
cells such as bacteria and spermatozoa. These organisms possess flagella, slender …

Cell motility in viscous fluids is ubiquitous and affects many biological processes, including
reproduction, infection and the marine life ecosystem. Here we review the biophysical and …

A huge number of bacterial species are motile by flagella, which allow them to actively move
toward favorable environments and away from hazardous areas and to conquer new …

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 …

The dynamics and deformations of immersed flexible fibers are at the heart of important
industrial and biological processes, induce peculiar mechanical and transport properties in …

Highlights•Different flagellar architectures enable different motility behaviors.•Strategies for
swimming and turning vary.•Flagella can push, pull, flick, and swing, roll, or wrap around the …

After a long gap following the classic work of Taylor, there have recently been several
studies dealing with hydrodynamic synchronization. It is now apparent that synchronization …

Sperm swimming at low Reynolds number have strong hydrodynamic interactions when
their concentration is high in vivo or near substrates in vitro. The beating tails not only propel …
