Run and twiddle

Bacterial chemotaxis is a subject that has attracted considerable attention over the last couple of decades. I came across this review in PNAS that gives an overview of the progress over the last 30 years:
Bacterial chemotaxis and the question of gain

I like the fact that the authors are still so excited about their topic they can'r resist sneaking an exclamation point in:
E. coli is able to sense aspartate over a range of at least 5 orders of magnitude in concentration by using just one molecular species of receptor!
