But particles in the air may be adding microscopic amounts of weight to some of the "official" kilograms around the world. Scientists have a new method of cleaning those weights.http://www.google-analytics.com/__utm.gif?utmac=UA-5828686-4&utmdt=Kilograms+With+Weight+Problems+May+Get+High-Tech+Cleanings&utme=8(APIKey)9(MDAxNzk1MDc4MDEyMTU0NTY4ODBlNmE3Yw001)
