Scientific paper

It is shown that the tension between recent neutrino oscillation experiments,
favoring sterile neutrinos with mass of 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.
