The MINOS experiment is a long-baseline neutrino experiment designed to study neutrino behaviour, in particular the phenomenon of neutrino oscillations. MINOS sends the NuMI neutrino beam through two detectors, a Near Detector 1 km downstream from the beam source at Fermilab, and a Far Detector 735 km away in the Soudan Mine in Minnesota. MINOS has been taking beam data since 2005. This document summarises recent neutrino oscillations results, with particular emphasis on electron neutrino appearance, which probes the angle θ13 of the neutrino mass mixing matrix. For an exposure of 8.2× 1020 protons on target, MINOS finds that sin2(2θ13)<0.12 for the normal mass hierarchy, and <0.20 for the inverted mass hierarchy at the 90% C.L., if the CP-violating phase δ=0.
