Limit on Tau Neutrino Mass from $τ^{-}\to π^{-}π^{+}π^{-}π^{0}ν_τ$
From a data sample of 29058 $τ^\pm\toπ^\pmπ^+π^-π^0ν_τ$ decays observed in the CLEO detector we derive a 95% confidence upper limit on the tau neutrino mass of 28 MeV.

First Observation of the Cabibbo Suppressed Decay $B^{+}\to \bar{D}^{0}K^{+}$
We have observed the decay of the $B^-$ meson into $D^0 K^-$, using 3.3 million $B\bar B$ pairs collected with the CLEO II detector at the Cornell Electron Storage Ring. We find the branching fractions of this decay to be suppressed relative to the decay into $D^0 π^-$ by $0.055 \pm 0.014 \pm 0.005$.
