Genome of invertebrate iridescent virus type 3 (mosquito iridescent virus).
Iridoviruses (IVs) are classified into five genera: Iridovirus and Chloriridovirus, whose members infect invertebrates, and Ranavirus, Lymphocystivirus, and Megalocytivirus, whose members infect vertebrates. Until now, Chloriridovirus was the only IV genus for which a representative and complete genomic sequence was not available. Here, we report the genome sequence and comparative analysis of ...
متن کاملIridescent clouds and distorted coronas.
Near-forward scattering of sunlight generates coronas and iridescence on clouds. Coronas are caused by diffraction, whereas iridescence is less easily explained. Iridescence often appears as bands of color aligned with the edges of clouds or as apparently random patches of color on clouds. This paper suggests that iridescence is due to interference between light that has been diffracted by a sp...
متن کاملFull-Color Biomimetic Photonic Materials with Iridescent and Non-Iridescent Structural Colors
The beautiful structural colors in bird feathers are some of the brightest colors in nature, and some of these colors are created by arrays of melanin granules that act as both structural colors and scattering absorbers. Inspired by the color of bird feathers, high-visibility structural colors have been created by altering four variables: size, blackness, refractive index, and arrangement of th...
متن کاملPolarimetry of Nacre in Iridescent Shells
We investigate the light transmitted or reflected from nacre (mother of pearl) taken from the iridescent shell of the bivalve Pinctada fucata. These nacre surfaces have a rich structure, composed of aragonite crystals arranged as tablets or bricks, 5 μm wide and 400-500 nm thick, surrounded by 30nm thick organic mortar. The light reflected from these shell surfaces, or transmitted through thin ...
متن کاملRendering Iridescent Colors of Optical Disks
The iridescent colors observed on objects such as optical disks are caused by light diffraction from their surface microstructure. We show that when an optical disk is illuminated by a light source it typically displays a major highlight strip of colors diagonally across the disk, consisting of saturated colors that vary along the strip, and a pair of weak strips of unsaturated colors that chan...
