...n then be compared to data from the lab, revealing gaps
in our understanding of the processes taking place. Researchers can use the model to test hypotheses that would fill in the missing pieces in silico before performing actual lab experiments. By running their model with a wide variety of gene mutat...

in knowledge of the way people respond to influenza, Wilson said two significant points emerged. "One concern is that most of the current influenza research is based on strains maintained in the lab, rather than wild influenza strains. Since we kno...
Scientists find new genes for Crohn's disease
... These latest results are helping to fill in the gaps
in knowledge about Crohn's and other IBDs, which affect more than 1 million Americans. Because IBDs tends to run in families and are more frequent in certain ethnic populations, especially Ashkenazi Jews, scientists have long suspected that they have...

in our samples, but we think most of this separation is genuine, a long-term consequence of geographic isolation." The original boundaries between groups may have been the emergence and growth of rivers, such as the Congo River, which is thought t...
