On the menu at the Rossmount Inn in Saint Andrews, New Brunswick, on the Atlantic coast of Canada, you may find kelp-wrapped salmon– avocado tartare with sesame cranberry– apple vinaigrette, citrus–soy glaze, cilantro, and chives. It sounds mouthwatering, but this is no ordinary seafood. The farmed seaweed (Saccharina latissima) and Atlantic salmon (Salmo salar) are not only side by side on the...

In order to obtain a compound stain to differentiate between mast and plasma cells, it was necessary to find dyes which provided a distinct colour contrast between the two types of cell. The aqueous acetic Alcian blue method (McManus and Mowry, 1960) stained mast cells, but also other tissue elements. Using Alcian blue at a pH less than 10 (Johnson and Helwig, 1963) the mast cells stained brill...

The first step in communicating color is to name it. The second step is color semiotics. The third step is introducing structure in the set of colors. In color education at all levels, this structure often takes the form of formulæ, like red + green = yellow, or turquoise + red = black. In recent times, Johannes Itten’s color theory and its associated color wheel have been very influential, mos...

Inhibitory effects have been reported when a target is preceded by a cue of the same color and location. Color-based inhibition was found using red and blue nonisoluminant stimuli (Law et al., 1995). Here we investigate whether this phenomenon depends on the chromatic subsystem involved by employing isoluminant colors varying along either the violet-yellow or purple-turquoise cardinal axis. Exp...

Cryptochrome 1a, located in the UV/violet-sensitive cones in the avian retina, is discussed as receptor molecule for the magnetic compass of birds. Our previous immunohistochemical studies of chicken retinae with an antiserum that labelled only activated cryptochrome 1a had shown activation of cryptochrome 1a under 373 nm UV, 424 nm blue, 502 nm turquoise and 565 nm green light. Green light, ho...

Preterm jaundiced infants were treated by phototherapy with a new turquoise fluorescent lamp. This was more effective in reducing plasma total bilirubin in relation to light irradiance than the ubiquitously used blue fluorescent lamp.
