Title: New and Exciting Cosmic Ray Results from MINOS

Abstract: The MINOS neutrino experiment also measures neutrinos and muons induced by cosmic rays interacting in the atmosphere. MINOS has measured atmospheric neutrinos both with contained events and upgoing muons. It has also made a measurement of the atmospheric muon charge ratio near 1 TeV with unprecedented accuracy. This ratio, which is larger than a host of previous measurements at lower muon energies, has implications for hadronic K production, for primary composition models and for event rates at neutrino telescopes.
