Cell migration in the absence of external cues is well described by a correlated random walk.Most single cells move by extending protrusions called pseudopodia.To deduce how cells walk, we have analyzed the formation of pseudopodia by Dictyostelium cells.We have observed that the formation of pseudopodia is highly ordered APP CONTROLLED with two ty

Microorganisms tend to adhere to food contact surfaces and form biofilms, which serve as reservoirs for bacteria that can contaminate food.As part of a biofilm, bacteria are protected from the stressful conditions found during food processing and become tolerant to antimicrobials, including traditional chemical sanitisers and disinfectants.Several

Dispersal is one of the key processes determining biodiversity.The passive sampling hypothesis, which emphasizes dispersal processes, suggests that larger habitats receive more species from the species pool as the main mechanism leading to more species in larger habitats than in smaller habitats (i.e., species-area relationships).However, the speci
