(Texas A&M University - Agricultural Communications) Dr. Jim Sacchettini does "virtual drug screening" to develop medicines for infectious diseases through a process he and a colleague developed to use Texas A&M University computers in off hours while they are not being used by students.

With some 2 million molecules to screen, that process might have taken 40 years to complete by old methods, Sacchettini said.

But it takes his lab just two weeks to process.
