Feedback Between Motion and Sensation Provides Nonlinear Boost in Run-and-tumble Navigation
Junjiajia Long, Steven W. Zucker, Thierry Emonet
Many organisms navigate gradients by alternating straight motions (runs) with random reorientations (tumbles), transiently suppressing tumbles whenever attractant signal increases.…

Adaptability of non-genetic diversity in bacterial chemotaxis
Nicholas W Frankel, William Pontius, Yann S Dufour +3
Bacterial chemotaxis systems are as diverse as the environments that bacteria inhabit, but how much environmental variation can cells tolerate with a single system? Diversification…

Polarization of photospheric lines from turbulent dynamo simulations
J. Sánchez Almeida, T. Emonet, F. Cattaneo
We employ the magnetic and velocity fields from turbulent dynamo simulations to synthesize the polarization of a typical photospheric line. The synthetic Stokes profiles have prope…
