Science journal could give recipe for deadly avian flu virus [View all]
A science journal is poised to publish a study that some experts believe could give a recipe to bioterrorists.
The study is from an experiment by a Dutch scientist who engineered the avian flu virus to make it more deadly to mammals by making it spread through the air.
That experiment was funded by the U.S. government, and it has sparked a passionate debate among scientists. Part of that debate is over where this research could lead, and whether it is worth it.
The National Institutes of Health and some scientists say it is worth it. They say it could ultimately protect mankind by trying to anticipate how the virus could mutate to one that causes a pandemic -- like the one in the film "Contagion."
