A new scaling variable is introduced in terms of which nuclear shadowing in deep-inelastic scattering is universal, i.e. independent of A, Q2 and x. This variable can be interpreted as a measure of the number of gluons probed by the hadronic fluctuations of a virtual photon during their lifetime. According to recent data from the H1 and ZEUS experiments, the gluon density in a proton rises steeply as x tends to zero. So nuclei which in the infinite momentum frame have a large surface density of gluons model at larger x values what we expect for the proton at much smaller x. Using experimental information on nuclear shadowing we predict the unitarity corrections to the proton structure function at small x and extract the bare Pomeron intercept.
