It is well known that a light, pseudo-scalar particle called the Axion can solve several fundamental physics problems. Proposed to explain the lack of a neutron EDM, such a weakly interacting particle has the right characteristics to explain formation of galaxies, by providing the needed mass in the form of Cold Dark Matter. Additionally, there has been data collected on the decay of several radioactive nuclei suggesting the need for weakly interacting particles streaming from the sun and throughout the galaxy. This talk will review the theory behind axion particles, examples of early experimental searches and some new search techniques. The nuclei data reviewed here can provide complimentary results to any existing axion searches as well as a novel type of search that can be conducted.
