Submission + - When Is A Kilogram Not A Kilogram? (yahoo.com)

Billosaur writes: "In what can only be a boon for those fighting weight gain, Yahoo! News is reporting that the International Bureau of Weights and Measures in Sevres, France (southwest of Paris) has discovered that the 118-year-old platinum-iridium cylinder used as the international standard for the kilogram is losing weight. So far, only about 50 micrograms, but physicists are baffled as to why. It is used to verify the weight of other standard kilogram weights used by other countries, and this could mean problems if kilogram has actually gotten lighter, but mainly for scientists and engineers. This is spurring discussions of replacing the current weight with something new which might be more stable, like a sphere made out of a Silicon-28 isotope crystal."
