the tsetse fly, Glossina morsitans. Source: Wikicommons, Author: Alan R. WalkerTsetse flies are responsible for the spread of African sleeping sickness and the animal disease nagana. They are large, long-lived flies, both males and females inflicting a painful bite when they take a blood meal. All tsetse flies belong to the genus Glossina and are found in large parts of tropical Africa.
Odorants are volatile chemicals produced by plants or animals, that can be sensed by an animal’s odor receptors. They can elicit specific behaviour patterns such as attraction to food sources. A recent paper published in Science has shed more light on pheromones involved in tsetse mating behaviour.Initial observations, made by the team based at Yale University, noted that male Glossina morsitans rapidly mount virgin females when a pair are placed together in a tube, and contact lasts several minutes. They show little interest in already mated females.

Researchers identify the origin of subset of autoantibodies that worsen lupusIn an effort to understand the origin of systemic lupus erythematosus and why some patients present with more severe disease than others, Johns Hopkins Medicine researchers say they have identified a type of autoantibody that may worsen the condition and have also found how these autoantibodies originate. They say their findings have implications for biomarker testing in lupus and may help identify patients that need early and aggressive treatment.
