to prevent or treat smallpox in humans. Thus, licensing of future medical countermeasures for smallpox will depend upon animal studies. The U.S. Food and Drug Administration (FDA) has established an animal efficacy rule to facilitate the approval of...
Daphne Koller named MacArthur Fellow
... The strength of this approach is that it has the ability
to represent models of the world with significant complexity. "So far, most models have been fairly self-contained -- but the world does not work that way," Koller said. These models have already seen service in analyzing the yeast genome, whe...
