The African turquoise killifish has recently gained significant traction as a new research organism in the aging field. Our understanding of aging has strongly benefited from canonical research organisms-yeast, C. elegans, Drosophila, zebrafish, and mice. Many characteristics that are essential to understand aging-for example, the adaptive immune system or the hypothalamo-pituitary axis-are onl...

Reichard et al. introduce the turquoise killifish (Nothobranchius furzeri), notable for its short-life span and diapause stage.

Color-grapheme synesthetes automatically perceive achromatic numbers as colored (e.g., 7 is turquoise). Up until recently, synesthesia was believed to be unidirectional. For instance, the number 7 gives rise to the percept of turquoise but the perception of turquoise does not trigger the number 7. However, some recent studies argue for bidirectional connections Cohen Kadosh et al., 2005; Johnso...

This study measures the influence of pH and polyaluminium chloride (PAC) dosage on the effectiveness of reactive dyes removal. Experiments were carried out for turquoise DG, red DB-8, orange OGR and black DN. The pH was changed from 3.5 to 7.0 and the dosages of PAC from 0.3 to 4.0 mg Al/mg dye. The degree of dyes removal depended on pH and dosage of coagulant. In the pH range from 4.0 to 5.5 t...

Kinship is central to an understanding of sociopolitical organization and the organization of production in Chaco Canyon. Between A.D. 700 and 900, lifeways in the Chacoan wor7ld underwent a transformation that reflects the evolution of matrilocal residence. Matrilocal groups became the foundation of a polity based on a corporate political strategy. Matrilocality provided the peoples of the Cha...

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...
