Abstract: We present recent DO results based on approximately 1 fb$^{-1}$ of $p \bar{p}$ collisions at $\sqrt{s} = 1.96$ TeV recorded at the Fermilab Tevatron. Preliminary results on a search for the flavor changing neutral current process $D^+\to π^+μ^+μ^-$, a measurement of the CP violation parameter in $B$ mixing, $ε_B$, and a two sided limit on the $B_s$ oscillation frequency $Δm_s$ are presented. The limits on $ε_B$ and ${\cal B}(D^+\to π^+μ^+μ^-)$ are the world's best limits. The two sided bound on $Δm_s$ is the first direct indication by a single experiment that $Δm_s$ is bounded from above.
