Lessons in bacterial attraction

A superior attraction bacterial foraging optimizer for global optimization

In order to improve the performance of basic bacterial foraging optimization (BFO) for various global optimization problems, a superior attraction bacterial foraging optimizer (SABFO) is proposed in this paper. In SABFO, a novel movement guiding technique termed as superior attraction strategy is introduced to make use of all bacteria historical experience as potential exemplars to lead individ...

Fatal attraction: bacterial bait lures worms to their death.

D uring the past decade, the roundworm Caenorhabditis elegans has become a popular model for the study of host/ pathogen relationships, leading to a wealth of information about microbial virulence factors and host defense pathways (1). Although the complicated interactions between C. elegans and the many pathogens that it encounters in the soil have become clearer in recent years, there is stil...

Molecular information processing: lessons from bacterial chemotaxis.

Extracellular information is converted into a usable intracellular form via signal transduction. This critically important process occurs in both unicellular and multicellular organisms throughout the living world and is exhibited by prokaryotic and eukaryotic cells alike. The mechanistic details of information processing in living cells vary from case to case, but diverse systems nevertheless ...

Thermal Robustness: Lessons from Bacterial Chemotaxis

Temperature changes affect reaction kinetics. How do signaling pathways cope with such global perturbation? A recent study dissects the solution found by bacterial chemotaxis.
