DangerousBeauty writes: Yahoo has a Canadian Press story up about new changes to the periodic table of elements, concerning the weight of specific elements, and the fact that the weights fluctuate based on where they are found in nature. From the article ""People are probably comfortable with having a single value for the atomic weight, but that is not the reality for our natural world." says University of Calgary associate professor Michael Wieser.
