The movement trajectories of organisms serve as dynamic read-outs of their behaviour and
physiology. For microorganisms this can be difficult to resolve due to their small size and fast …

Motility is one of the most dynamic features of the microbial world. The ability to swim or
crawl frequently governs how microorganisms interact with their physical and chemical …

Gradients in fluid viscosity characterize microbiomes ranging from mucus layers on marine
organisms and human viscera, to biofilms. Although such environments are widely …

Understanding the motility behavior of bacteria in confining microenvironments, in which
they search for available physical space and move in response to stimuli, is important for …

The incessant activity of swimming microorganisms has a direct physical effect on
surrounding microscopic objects, leading to enhanced diffusion far beyond the level of …

Functional cilia and flagella are crucial to the propulsion of physiological fluids, motile cells,
and microorganisms. Motility assessment of individual cells allows discrimination of normal …

Cellular appendages such as cilia and flagella represent universal tools enabling cells and
microbes, among other essential functionalities, to propel themselves in diverse …

The behavior and microscale processes associated with freely suspended organisms, along
with sinking particles underlie key ecological processes in the ocean. Mechanistically …

Microorganisms swimming through viscous fluids imprint their propulsion mechanisms in the
flow fields they generate. Extreme confinement of these swimmers between rigid boundaries …

Self-propulsion of cellular microswimmers generates flow signatures, commonly classified
as pusher and puller type, which characterize hydrodynamic interactions with other cells or …
