  Encompasing a volume of ~1 km^3 of glacial ice at the South Pole, IceCube is
currently the worlds largest neutrino detector. It consists of 5160 optical
modules on 86 strings in a depth between 1450m and 2450m, as well as 324
optical modules arranged in 81 stations on the surface to detect charged cosmic
rays. A large amount of data has already been acquired with smaller
configurations throughout the installation period. Using this data the
atmospheric neutrino spectrum in the northern hemisphere has been measured up
to 100 TeV. No point sources have been identified in a set of more than 10^5
neutrino candidates from both hemispheres. Searches for transient sources have
set stringent limits on neutrino emission from gamma-ray bursts, and are now
accompanied by an extensive neutrino-triggered follow-up program. A very large
statistics of cosmic ray events has revealed an anisotropy in the cosmic ray
flux on the 10^-3 level in the 10-100 TeV range. While no sources of
extra-terrestrial neutrinos have been found yet, the physics results obtained
so far illustrate the very good performance of the detector.
