Survival of all animals depends on an accurate representation of the world, and an organism
must be capable of prioritizing and responding to potentially hazardous conditions. This …

This article describes the fabrication and use of microfluidic devices for investigating spatial
orientation behaviors in nematode worms (Caenorhabditis elegans). Until now, spatial …

Swimming organisms in their natural habitat need to navigate through a wide range of
geometries and chemical environments. Interaction with boundaries in such situations is …

Theoretical and empirical investigations of search strategies typically have failed to
distinguish the distinct roles played by density versus patchiness of resources. It is well …

Active oscillators, with purely hydrodynamic coupling, are useful simple models to
understand various aspects of motile cilia synchronization. Motile cilia are used by …

Bacteria can chemotactically migrate up attractant gradients by controlling run-and-tumble
motility patterns. In addition to this well-known chemotactic behaviour, several soil and …

Paramecium or other ciliates have the potential to be utilized for minimally invasive surgery
systems, making internal body organs accessible. Paramecium shows interesting responses …

Understanding when, how, and if bacteria swim is key to understanding critical ecological
and biological processes, from carbon cycling to infection. Imaging motility by traditional light …

Motility of microorganisms is understudied but provides useful insights into their behavior.
Organisms' ability to move autonomously changes how they interact with their environment …

Beneficial to the steady control of flow properties and concentration gradient profiles,
quantification of cell chemotaxis based on microfluidic devices could achieve on the scale of …
