We consider impact of the recent data obtained by the LHC, Tevatron, and fixed-target experiments on the quark distributions in the nucleon with a particular focus on disentangling of different quark species. Improved determination of the poorly known strange sea distribution is obtained and the standard candle benchmarks for the Drell-Yan process at the LHC are updated.
