MINOS searches for neutrino oscillations using the disappearance of muon neutrinos between two detectors, over a baseline of 735 km. We recently reported the most precise measurement of neutrino oscillations in the atmospheric sector and the first tagged measurement of antineutrino oscillations. The neutrino mass splitting and mixing angle are measured to be |Δm2| = 2.32-0.08+0.12 × 10-3 eV2 and sin22θ> 0.90 (90% C.L.) for an exposure of 7.25 × 1020 protons-on-target (PoT). Antineutrino oscillation parameters are measured as Δm2=(3.36+0.46-0.40\textrm(stat.)±0.06\textrm(syst.))× 10-3 eV2 and sin2(2θ)=0.86+0.11-0.12\textrm(stat.)±0.01\textrm(syst.) with an exposure of 1.7 × 1020 PoT in NuMI antineutrino running mode. We use the apparent difference in neutrino and antineutrino oscillation parameters to constrain non-standard matter interactions which could occur during propagation through the Earth's crust to the far detector.
