President John F. Kennedy was assassinated in Dallas, Texas, on November 22, 1963 - almost 50 years ago. Vice president Lyndon B. Johnson was swiftly sworn in aboard Air Force One with former first lady, Jacqueline Kennedy, at his side. Cecil Stoughton, who had been president Kennedy's official photographer, captured the ceremony. I've attempted to colorize that photo.

A bunch of folks who are much smarter than me have proved a link between blue spectrum light (i.e. light in the 460 to 480 nm range) and the body's melatonin production. Melatonin is a hormone that (inter alia) makes you sleepy. This knowledge is especially helpful to people suffering from insomnia or circadian rhythm disorders.
