Zeta potential, defined as the electric charge at the shear plane, is widely used as a proxy parameter for bacteria cell surface charge. Nonspecific adsorption of ions or polyelectrolytes onto the cell surface, however, alters the value and polarity of the measured...

Flies use specialized photoreceptors R7 and R8 in the dorsal rim area (DRA) to detect skylight polarization. R7 and R8 form a tiered waveguide (rhabdom) with R7 on top, filtering light delivered to R8. We examine how the division of a given resource, rhabdom length,...
