The physical mechanisms and physiological causes of glare in human vision are reviewed. These mechanisms are scattering in the cornea, lens, and retina, and diffraction in the coherent cell structures on the outer radial areas of the lens. This scattering and diffraction are responsible for the " bloom " and " flare lines " seen around very bright objects.(More)

Thermophilic microbial inhabitants of active seafloor and continental hot springs populate the deepest branches of the universal phyloge-netic tree, making hydrothermal ecosystems the most ancient continuously inhabited ecosystems on Earth. Geochemical consequences of hot water-rock interactions render these environments habitable and supply a diverse array(More)
