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 …

Activity and autonomous motion are fundamental in living and engineering systems. This
has stimulated the new field of'active matter'in recent years, which focuses on the physical …

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 …

The flagellum is an important organelle for the survival of bacteria and consists of a basal
body, hook, and filament. The FlgE protein is the subunit of the hook that connects the basal …

Accurate frictional contact is critical in simulating the assembly of rod-like structures in the
practical world, such as knots, hairs, flagella, and more. Due to their high geometric …

Trajectories and conformations of uni-and multiflagellar bacteria are studied with a coarse-
grained model of a cell comprised of elastic flagella connected to a cell body. The elasticities …

For many bacteria, motility stems from one or more flagella, each rotated by the bacterial
flagellar motor, a powerful rotary molecular machine. The hook, a soft polymer at the base of …

Peritrichously flagellated bacteria swim in a fluid environment by rotating motors embedded
in the cell membrane and consequently rotating multiple helical flagella. We present a novel …

The bacterial hook, as a universal joint coupling rotation of the flagellar motor and the
filament, is an important component of the flagellum that propels the bacteria to swim. The …

Microorganisms navigate through fluid, often confined by complex environments, to survive
and sustain life. Inspired by this fact, we consider a model system and seek to understand …
