Encyclopedia Britannica still reports that speed of light in a vacuum, C, is still considered a universal constant. So whatever your 2013 article was hypothesizing either has not been experimentally verified and gained wide acceptance, or it describes an esoteric property of light which does not fundamentally change the status of C as a universal constant.
