The role of chemical communication in mate choice
Article Abstract:
The chemical composition and release rates of pheromones- the chemicals responsible for coordination of mates in sexual activity vary in different individuals and also have an impact on the mate quality. The results of the study on the characters of pheromones show that growth rate, immunocompetence and longevity are dependent on the pheromonal activity thus confirming the high metabolic cost of production, mate quality, and high levels of heritability.

Aggregation in Azospirillum brasilense: effects of chemical and physical factors and involvement of extracellular components
Article Abstract:
The extracellular factors as well as the chemical and physical issues involved in the aggregation of Azospirillum brasilense cells were examined using a medium for consistent induction of aggregation. Results showed the occurrence of visible flocculation following the use of fructose and ammonium chloride in growing the A. brasilense strain, The strongest aggregation were observed from a mutant that lacks both lateral and polar flagella.

Chemical technologies for probing glycans
Article Abstract:
The absence of suitable technologies has hindered efforts to define the functions of glycans at the molecular levels. The emergence of chemical tools that could highlight the way these vital biopolymers operate is discussed.
