In science:

If we consider chemical signals in the environment, the corresponding motility behavior is called chemotaxis or chemokinesis, depending on whether the organism senses the direction of signal gradients directly, or responds by changing its speed or the frequency of turning.
An equation-free computational approach for extracting population-level behavior from individual-based models of biological dispersal
This growth has been spurred in part by new experimental techniques for studying cell motility.
The hydrodynamics of swimming microorganisms
Traditionally, motile cells have been passively observed and tracked using light microscopy.
The hydrodynamics of swimming microorganisms
Advances in visualization techniques, such as the fluorescent staining of flagella in living, swimming bacteria, continue to elucidate the mechanics of motility. A powerful new contribution is the ability to measure forces at the scale of single organisms and single motors.
The hydrodynamics of swimming microorganisms
In this section we motivate our review with a short overview of mechanisms for swimming motility.
The hydrodynamics of swimming microorganisms
For example, the organelle of motility in E. coli and Salmonel la typhimurium is the bacterial flagellum, consisting of a rotary motor, a helical filament, and a hook which connects the motor to the filament [34, 35, 36].
The hydrodynamics of swimming microorganisms
For a non-motile E. coli bacterium at room temperature, we have [D] ∼ 0.1 µm2 /s in water; while the time scale for thermal reorientation of the cell axis, [DR ]−1 , is a few minutes.
The hydrodynamics of swimming microorganisms
In addition to affecting the concentration of chemical species that influence the motility of microorganisms [199], boundaries modify the hydrodynamic stresses acting on the cells, and near-wall motility is therefore both biologically and physically different from bulk motility.
The hydrodynamics of swimming microorganisms
Near a wall, the chiral propulsion mechanism leads a breaking of the (timeaveraged) axisymmetry of the propulsive force because new non-zero components arise in the motility matrix of the helix.
