The addition of the EMTiming system installed to provide the time measurements of the electromagnetic calorimeter signals has significantly increased the sensitivity of CDF to events with a photon and a missing energy. Here I review recent searches in this signature performed by CDF using data from proton-antiproton collisions at the center of mass energy of 1.96 TeV. They provide new constraints on models with large extra dimensions and with gauge mediated supersymmetry breaking.
