Chemotaxis, the process by which cells move towards soluble factors, is one of the most fascinating areas of modern biology. For cells to migrate up an attractant gradient they must detect signals, ...

Rhythmic patterns and precise motions—these are key elements of proper swimming. Olympians demonstrate repeated patterns of breathing, with synchronized head, leg and arm movements, enthralling ...

Most eukaryotic cells move by locally protruding actin-rich pseudopods while retracting other regions of the cell body 2. During chemotaxis, cells are able to perceive the directions of chemical ...

Rhythmic patterns and precise motions are key elements of proper swimming, and comparable demonstrations of this pattern repetition and power usage can be seen in a microscopic swimmer -- the amoeboid ...
