The Army is starting construction on a bio-defense laboratory building at Fort Detrick in Frederick, Md. The building will be the new home for the Army's Medical Institute of Infectious Diseases. Research there will focus on the world's deadliest pathogens. By the end of 2015, as many as 952 people are expected to work there. That's up from about 800 working in current facilities built in the 1950s and 1960s.
Critics says planners haven't fully considered the risk of a release of infectious organisms from the lab. The National Academy of Sciences will begin a health and safety review of the project.
