The Super-Kamiokande data from the first phase of the detector activity from April 1996 to July 2001 have been recently reanalysed and the new results are reported. Solar neutrino data allowed for precision analysis of oscillation parameters. When combined with the latest results from SNO and KamLAND experiments the best fit parameters of ue\leftrightarrow u\mu au\ transitions are \delta m2=(7.1+0.6-0.5)\times 10-5 eV2 and tan2 \theta =0.44\pm 0.08. The atmospheric neutrino sample is compared with the updated simulations taking into account flux calculations based on new primary cosmic ray measurements and modifications introduced to neutrino interaction model thanks to measurements in the near detectors of the K2K experiment. The new analysis based on a subsample of higher precision events allowed to reveal a dip in the distribution of the ratio of the distance over neutrino energy, presenting thus the first oscillatory behavior in neutrino data. As a result the parameters of the transitions \nu \mu \leftrightarrow \nu \tau are better constrained: 1.9\times 10-3 < \Delta m2 < 3.0\times 10-3 eV2 and sin22\theta > 0.90 at 90\% C.L. The atmospheric neutrino oscillations have been confirmed by the first long-baseline accelerator experiment, K2K, using the neutrino beam produced at KEK and interactions recorded in the Super-Kamiokande detector. The results from the phase I as well as phase II of the experiment show a deficit of muon neutrinos consistent with the atmospheric neutrino oscillations. Finally the most recent results on searches for proton decays are presented.
