Hypersonic soundwave manipulator
From Tardis Wiki, the free Doctor Who reference
The Genetic Manipulation Device was invented by Professor Richard Lazarus. The machine would turn anyone inside decades younger, but the process contained one side effect: genes that evolution rejected and left dormant would be unlocked, transforming the human into a giant skeletal scorpion-like beast that fed off the lifeforce of living creatures. (DW: The Lazarus Experiment)
Harold Saxon supported Lazarus's research so that he could copy, improve and focus the technology into his Laser screwdriver and reverse it to age people forward. (DW: The Sound of Drums)
