Query: Universal triviality of the Chow group of 0-cycles and the Brauer group   We prove that a smooth proper universally CH_0-trivial variety X over a field
k has universally trivial Brauer group. This fills a gap in the literature
concerning the p-torsion of the Brauer group when k has characteristic p.
