According to the [[Tenth Doctor]], the '''Tandocca Scale''' was a "series of [[wavelength]]s used as a carrier signal by [[Migrant Bee]]s" that helped explain why the bees had disappeared from early [[21st century]] [[Earth]]. He went on to tell [[Donna Noble]] that the wavelengths were "infinitely small... like looking for a speck of [[cinnamon]] in the [[Sahara Desert|Sahara]]." The Doctor's discovery of the Tandocca Scale allowed him to see a "Tandocca trail" — a path by which [[Earth]] and 26 other celestial bodies had been moved by [[Davros]] and the [[Dalek]]s into the [[Medusa Cascade]]. He was then able to use that trail to pilot [[the TARDIS]] back to the "stolen" [[Earth]]. ([[TV]]: ''[[The Stolen Earth (TV story)|The Stolen Earth]]'')
