According to the researchers at Cornell University, a technical marvel, cilia have proved difficult to reproduce in engineering applications, especially at the microscale.

Cilia are the body's diligent ushers. These microscopic hairs, which move fluid by rhythmic beating, are responsible for pushing cerebrospinal fluid in your brain, clearing the phlegm and dirt from your lungs, and keeping other organs and tissues clean.

Cell-spanning whirlpools in the immature egg cells of animals such as mice, zebrafish and fruit flies quickly mix the cells innards, but scientists didnt know how these flows form. Using mathematical modeling, researchers have found an answer. The gyres result from the collective behavior of rodlike molecular tubes called microtubules that extend inward from the cells membranes, the researchers report.
