It is shown that the tension between recent neutrino oscillation experiments, favoring sterile neutrinos with masses of the order of 1 eV, and cosmological data which impose stringent constraints on neutrino masses from the free streaming suppression of density fluctuations, can be resolved in models of the present accelerated expansion of the Universe based on f(R) gravity.

    In two f(R) gravity models, a specific matter-curvature interaction shifts the fixed points and can create stable late-time accelerating attractors, but the attractors appear only for parameter values outside the mode...
