The last five decades of molecular and systems biology research have provided unprecedented
insights into the molecular and genetic basis of many cellular processes. Despite these …

… We thank Jerko Rosko, Dejan Kunovac and all other members of the Pilizota and Swain lab
for their comments and support, Andrew Schofield for granting us access to the refractometer …

The bacterial flagellar switch that controls the direction of flagellar rotation during chemotaxis
has a highly cooperative response. This has previously been understood in terms of the …

… (5) ℓ g ( coli ) = k B T Δ ρ g V cell ≈ 4 μ m , for an E. coli with V cell … 4, give essentially
identical results, 9 so that the decreasing v ( t ) is not due to gradual kinematic accumulation at …

… (t), in illuminated squares of different sizes is shown in Fig. 3a, from which we extracted t D ,
… Equations (1) and (2) are also confirmed by the data collapse achieved for ρ tot (t) when we …

… where we denote the growth curve as y(t). The doubling time is ln(2) times the inverse of the
growth rate. We define the lag time as the … If this point of maximum growth rate is at t=t*, then …

… time of hyperosmotic shock, t 1 . For this, d(V(t))/dt was calculated using V(t) from the beginning
of … Then t 1 = t min−1 where t min is the time at which d(V(t))/dt is minimal and V min is the …

… F T includes fluorescence due to dye bound to the membrane (F m ) as well as fluorescence
… Lines are exponential fits, F T = A 0 + A 1 exp{−t/t 0 }, time constants t 0 are given in the text. …

… (A) Averaged total and cytoplasmic volume, (B) length, and (C) width traces in time during
dextran shocks of different magnitudes (Vn(t), Ln(t), Wn(t)). Data points are recorded at 0.5 Hz …

Many bacterial species swim by employing ion-driven molecular motors that power the rotation
of helical filaments. Signals are transmitted to the motor from the external environment via …
