Whiter than White

Geoengineering: Whiter skies?

[1] One proposed side effect of geoengineering with stratospheric sulfate aerosols is sky whitening during the day and afterglows near sunset, as is seen after large volcanic eruptions. Sulfate aerosols in the stratosphere would increase diffuse light received at the surface, but with a non-uniform spectral distribution. We use a radiative transfer model to calculate spectral irradiance for ide...

Mouse Strain Backgrounds: More Than Black and White

two suggested, among them neuronal excitability and Mouse Strain Backgrounds: degeneration (Messer et al., 1992; Schauwecker and More Than Black and White Steward, 1997; Cox et al., 1997; Hamilton et al., 1997) and hearing loss (Erway et al., 1993). A recent Viewpoint in Neuron, which arose from a BanAn extended panelof readily available common inbred strains that would serve neuroscientists we...

The quest for a whiter shade of pale in skin care

The quest for a whiter shade of pale dates back to ancient civilizations, when a pale complexion was associated with aristocratic lineage. During the Tang dynasty (618-907), Chinese women used ground pearl powder as a whitening make-up. In ancient Persia, field workers bleached their skin with pure natural hydroquinone to keep it from darkening under the sun. In Europe, during the Renaissance, ...

A whiter shade of pale, a blacker shade of dark: Parameters of spatially induced blackness.

The surface-mode property of "blackness" is induced by simultaneous contrast with an adjacent, more luminant surround. As numerous studies have shown, the degree of blackness induced within an achromatic test field is a function of the relative luminance of the adjacent chromatic inducing field, but not of its hue. But in the converse case of chromatic test fields, susceptibility to blackening ...
