Although three Los Alamos National Laboratory computers were "taken" from a scientist's home and another employee's BlackBerry was lost in an unidentified "sensitive foreign country," officials say no sensitive information was lost, according to the Associated Press.

This isn't the first time the lab has taken heat over its seemingly lax security. In July 2007, classified documents were found during a trailer-park drug raid. And last August, a report by the U.S. Government Accountability Office found that the lab's unclassified network contained nuclear information as well as employee data.

Still, the lab maintains that the recent equipment losses do not constitute security breaches as none of the devices contained sensitive information. The National Nuclear Security Administration is looking into the incidents.
