Neutrino masses and the number of light neutrino species can be tested in a variety of laboratory experiments and also can be constrained by particle astrophysics and precision cosmology. A conflict between these various results could be an indication of new physics in the neutrino sector. In this paper, we explore the possibility for reconciliation of otherwise discrepant results in a simple model containing a light scalar field which produces mass-varying neutrinos. We extend previous work on mass-varying neutrinos to consider issues of neutrino clumping, the effects of additional contributions to neutrino mass, and reconciliation of eV mass sterile neutrinos with cosmology.
