We report measurements of direct CP-violating asymmetries in charmless decays of neutral bottom hadrons to pairs of charged hadrons with the upgraded Collider Detector at the Fermilab Tevatron. Using a data sample corresponding to 1 fb(-1) of integrated luminosity, we obtain the first measurements of direct CP violation in bottom strange mesons, A(CP)(B(s)(0)?K(-)?(+))=+0.39±0.15(stat)±0.08(syst), and bottom baryons, A(CP)(?(b)(0)?p?(-))=+0.03±0.17(stat)±0.05(syst) and A(CP)(?(b)(0)?pK(-))=+0.37±0.17(stat)±0.03(syst). In addition, we measure CP violation in B(0)?K(+)?(-) decays with 3.5? significance, A(CP)(B(0)?K(+)?(-))=-0.086±0.023(stat)±0.009(syst), in agreement with the current world average. Measurements of branching fractions of B(s)(0)?K(+)K(-) and B(0)??(+)?(-) decays are also updated.
