Direct detection experiments have traditionally looked for nuclear recoils. In the last few years, experiments have also started looking for electron recoils, reaching thresholds of ~ eV. As experiments achieve these low thresholds, they also encounter new and previously unexplored backgrounds. In this seminar, I will discuss about new low energy backgrounds correlated with previously considered high energy backgrounds like cosmic rays and radiogenic photons in current as well as future low threshold detectors. In the end, I will also briefly comment about using direct detection experiments as neutrino detectors, and the possibilities of probing new neutrino physics with them.
