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(B0(s) --> K-pi++) ÿ0.39 +/- 0.15 (stat) +/- 0.08 (syst), and
bottom baryons, A_CP(Lambda0(b) --> p pi+-) ÿ0.03 +/- 0.17 (stat) +/-
0.05 (syst) and A_CP(Lambda0(b) --> pK-) ÿ0.37 +/- 0.17 (stat) +/- 0.03
(syst). In addition, we measure CP violation in B0 --> K+pi+- decays
with 3.5 sigma significance, A_CP(B0 --> K+ pi+-) ÿ0.086 +/- 0.023
(stat) +/- 0.009 (syst), in agreement with the current world average.
Measurements of branching fractions of B0(s) --> K+ k- and B0 -->
pi++ pi+- decays are also updated.
