Topological features of vector vortex beams perturbed with uniformly polarized light
, 2017 Optical singularities manifesting at the center of vector vortex beams are unstable, since their topological charge is higher than the lowest value permitted by Maxwell’s equations. Inspired by conceptually similar phenomena occurring in the polarization

Opsin expression, physiological characterization and identification of photoreceptor cells in the dorsal rim area and main retina of the desert locust, Schistocerca gregaria. [PDF]
, 2014 For compass orientation many insects rely on the pattern of sky polarization, but some species also exploit the sky chromatic contrast. Desert locusts, Schistocerca gregaria, detect polarized light through a specialized dorsal rim area (DRA) in their ...

Flying Drosophila maintain arbitrary but stable headings relative to the angle of polarized light [PDF]
, 2018 Animals must use external cues to maintain a straight course over long distances. In this study, we investigated how the fruit fly Drosophila melanogaster selects and maintains a flight heading relative to the axis of linearly polarized light, a visual ...

Spectral properties of identified polarized-light sensitive interneurons in the brain of the desert locust Schistocerca gregaria [PDF]
, 2007 Many migrating animals employ a celestial compass mechanism for spatial navigation. Behavioral experimentsin bees and ants have shown that sun compass navigation may rely on the spectral gradient in the sky as well as onthe pattern of sky polarization ...
