Multiple astrophysical observations have confirmed that ordinary (baryonic) matter makes up only ~15% of the observable matter in the universe. The composition of the remaining non-luminous (dark) matter continues to elude experimental detection. The Cryogenic Dark Matter Search is looking for the potential rare collision between ordinary matter and a prime dark matter candidate, the weakly interacting massive particle (WIMP). For many years, CDMS has led the field of direct detection with the use of ionization and athermal phonon signals to discriminate between candidate WIMP interactions (nuclear recoil) and background (electron recoil) events. I will present recent results from CDMS. I will also discuss the transition to SuperCDMS, including the current status of the 10-kg experiment at Soudan and plans to launch a 100-kg Ge experiment at SNOLAB.
