Most swimming bacteria are capable of following gradients of nutrients, signaling molecules
and other environmental factors that affect bacterial physiology. This tactic behavior became …

Osmosis is a universal phenomenon occurring in a broad variety of processes and fields. It
is the archetype of entropic forces, both trivial in its fundamental expression–the van't Hoff …

Chemotaxis allows bacteria to follow gradients of nutrients and other environmental stimuli.
The bacterium Escherichia coli performs chemotaxis via a run-and-tumble strategy in which …

Organisms acquire and use information from their environment to guide their behaviour.
However, it is unclear whether this information quantitatively limits their performance at …

Molecular gradients play an important role in diverse physiological and pathological
phenomena such as immune response, wound healing, development and cancer …

Experimental observations indicate that, at sufficiently high cell densities, swimming bacteria
exhibit coordinated motions on length scales (10 to 100 μm) that are large compared with …

The past two decades have seen a remarkable progress in the development of synthetic
colloidal agents which are capable of creating directed motion in an unbiased environment …

Microfluidics has significantly contributed to the expansion of the frontiers of microbial
ecology over the past decade by allowing researchers to observe the behaviors of microbes …

Chemotactic bacteria are known to collectively migrate towards sources of attractants. In
confined convectionless geometries, concentration “waves” of swimming Escherichia coli …

The Escherichia coli chemotaxis‐signaling pathway computes time derivatives of
chemoeffector concentrations. This network features modules for signal …
