I've read (today's NY Times) that blue light is radiated from computers and will keep one from falling asleep at night. Thus, one should not use a computer in the hour prior to going to bed. Is this a true?
iPhoto '11, Mac OS X (10.6.8)
According to the research I can find, it would apply to any device that emits blue light; a computer, an iPad, a TV or even a blue light bulb. LCD displays emit more blue light than did old CRT-type displays, apparently, so any LCD device would, if this research is valid (the studies seem to be on very small samples) have more effect.
I don't know what the NYT posted today - I don't see anything new on the subject in the online edition - but this article from 2011 seems to have a pretty good discussion on the issue:

Does my iPad give off "blue light" as does an iMac and other PCs?
