As is typical in particle physics, the development of a new detector technology opens up many new avenues of research.  The advent of the PPC Germanium detector, the core technology of the CoGeNT experiment continues this trend. I will discuss briefly the history of the project, beginning with efforts to measure coherent neutrino-nucleus scattering. The role of the PPC detectors in the Majorana zero-neutrino double-beta decay experiment will also be explained. Finally, I will cover the recent developments of the observation of a large excess of nuclear recoils consistent with interactions from light WIMPS, as well as the subsequent suggestion of an annual modulation of these events.
