IceCube is a cubic kilo-meter scale, deep-ice neutrino Cherenkov detector at the South Pole. The partial IceCube detector has been in operation since 2005, and the full IceCube detector is operational since May 2011. IceCube's high energy neutrino searches cover an energy region of the TeV and lower energies, and also the much higher energy region up to EeV regime. In the TeV-PeV region, the potential astrophysical neutrino sources includes active galactic nuclei, gamma-ray bursts and supernova remnants. In the EeV regime, neutrinos channelled from ultra-high energy cosmic-ray emissions which play leading roles in the flow of astrophysical energies are expected.

IceCube surveys diffusive neutrino emissions and point-like sources of neutrinos with the world's best sensitivity from TeV energies to far beyond. In this seminar, the recent results from high energy neutrino searches by IceCube will be presented, followed by their implication to particle physics such as constraints on the neutrino-nucleus interaction cross-sections. Finally, the future upgrade plans for the IceCube observatory will be described.
