Strange sea asymmetry from global QCD fits
  We present a preliminary account of a new global QCD analysis of DIS data, including recent $\nu, \bar \nu$ DIS measurements. The model-independent cross section reanalysis by CCFR allows a new determination of the strange sea asymmetry, whose first moment is found to be small. The impact on the NuTeV measurement of $\sin^2 \theta_W$ is discussed.
