Eukaryotic flagella, whip-like organelles that elegantly propel microorganisms and pump fluid, seem to embody simplicity on the microscopic scale. But appearances can be deceptive: Flagella are ...

Eukaryotic cilia and flagella are essential organelles that extend from the cell surface, playing crucial roles in sensory ...

When headed the wrong way, some bacteria turn by letting their propellers flop. The newly discovered turning mechanism explains how a marine bacterium can control its direction using only a single ...

We precisely measure the force-free swimming speed of a rotating helix in viscous and viscoelastic fluids. The fluids are highly viscous to replicate the low Reynolds number environment of ...

Researchers have developed a new model to study the motion patterns of bacteria in real time and to determine how these motions relate to communication within a bacterial colony. They chemically ...

Flagella are primarily used for cell movement and are found in prokaryotes as well as some eukaryotes. The prokaryotic flagellum spins, creating forward movement by a corkscrew shaped filament. A ...

THREE years before his death in 1805, English philosopher William Paley proposed a now-famous thought experiment. Imagine discovering a watch on the heath: how would you explain its intricate ...

Actually, flagella vary widely from one species to another, and some of the components can perform useful functions by themselves. They are anything but irreducibly complex It is a highly complex ...

One essential component of each eukaryotic cell is the cytoskeleton. Microtubules, tiny tubes consisting of a protein called tubulin, are part of this skeleton of cells. Cilia and flagella, which are ...
