We're no experts on medical research. Nonetheless, we offer this humble safety tip to those who are: When conducting experiments on deadly pathogens, safety protocols must be extremely restrictive and strictly followed. Always.
It should go without saying, but amazingly, employees at the until-now-revered Centers for Disease Control and Prevention in Atlanta didn't get the memo. The nation's pre-eminent medical research laboratory has been rocked by revelations of scientists' sloppy handling of anthrax and an extremely dangerous strain of the deadly bird flu. (This around the time the also highly respected National Institutes of Health found a box of smallpox vials lying around a storage area. It had been there for 60 years, but still, not a good summer for health institutions.)
Among its many functions, the CDC actually sets safety and security standards for dealing with dangerous pathogens, but its own internal investigation revealed that it has not always lived up to the standards itself. It's pretty much a miracle that people haven't been killed.
