I will present both the experimental results and the theory for the non-equilibrium fluctuations of electric current in mesoscopic systems (diffusive wires and chaotic quantum dots). Non-interacting electrons exhibit Poissonian statistics while correlations in mesoscopic systems lead to the universality of current fluctuations. I will consider the effects of spin-polarized transport on the noise and magnetoresistance of spintronic systems. Finally, the electron-optical analogies will be discussed in relation to the fluctuations of radiation from chaotic absorbing ('grey body') and amplifying ('random laser') optical media.
