Strength in numbers
For more than ten years the nematode Caenorhabditis elegans has proven to be a valuable model for studies of the host response to various bacterial and fungal pathogens.

On the other hand if the cost of building a quorum is too high ...

A recent workshop held at the Arizona State University Center for Social Dynamics and Complexity gathered over 50 prominent researchers from around the globe to discuss the development of genomic resources for several ant species. Ants play crucial roles in many ecological niches and the sequencing of several ant genomes promises to elucidate topics ranging from the genetic basis for social com...
متن کاملGenetic markers in glaucoma.
A number of genetic polymorphisms have been investigated in Negro and Caucasoid patients with glaucoma and the results compared with data obtained on healthy controls. A sample of 61 Negro patients was not significantly different from a sample of 238 controls with respect to 18 red cell and serum protein systems; no association between glaucoma and any of these systems could be demonstrated.
