Run (and Tumble) to Dinner



Researchers calculated the optimal search strategy for organisms that employ run-and-tumble motion when looking for a food’s odor. They determined that the chemotaxis demonstrated by E. coli closely resembles this system when accounting for the costs of control and the noise of the environment. This work may lead to new methods of designing chemical-seeking drones or nanobots.
