Horseflies misjudge landings on zebra patterns, compared with solid gray or black surfaces, which provides evidence for why evolution came up with the black-and-white pattern. Everyone loves zebras.

Medvedev modeled wave diffraction off a circular reflecting region with radially varying index of refraction outside of it to better understand the Crab Nebula’s zebra pattern. LAWRENCE — A ...

Scientists have discovered a new, persistent structure in one of two radiation belts surrounding Earth. NASA's twin Van Allen Probes spacecraft have shown that high-energy electrons in the inner ...
