CNN has dropped to a new low in terms of very bad science news reporting. This news report is so bad, and has so many factual errors in it, one simply should not pay any attention to it completely. http://lightyears.blogs.cnn.com/2012/06/07/sharp-as-a-laser/ Note that even the topic is glaringly wrong. Saying that x-ray might replace a laser implies that these are two different things. A "laser" is simply a coherent beam of EM radiation. X-ray is an EM radiation. This means that X-ray isn't excluded from becoming a laser. And that is what has been accomplished at SLAC's LCLS - an x-ray laser! If you want to read a better coverage of this work, read this: http://www.rdmag.com/News/2012/06/M...fast-Lasers-To-Create-Tabletop-X-Ray-Devices/ Moral of the story: never pay any attention to science reports out of CNN from now on.
