A Science article published on July 9, 2010, describes the discovery of an alternative form of evolution that helps Drosophila flies conquer nematodes that sterilize them. Nematodes are among the most abundant, diverse and destructive parasites of plants and animals.
The article, titled, "Adaptation via Symbiosis; Recent Spread of a Drosophila Defensive Symbiont", is by John Jaenike of the University of Rochester and his colleagues. In a video interview, Jaenike explains the results of this study and their implications for developing treatments for serious human diseases, including river blindness, caused by nematodes; about 17.7 million people worldwide are currently infected with river blindness.
"The protection of an insect from a potent nematode parasite by a bacterial infection is of potential importance in both medicine and agriculture," says George Gilchrist, a program director at the National Science Foundation. "This study adds a new page to the catalogue of interactions between animals and bacteria."
The Science study is also discussed in a press release from the University of Rochester.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
