A healthy extension of Horava gravity
  We propose a natural extension of Horava's model for quantum gravity, which
is free from the notorious pathologies of the original proposal. The new model
endows the scalar graviton mode with a regular quadratic action and remains
power-counting renormalizable. At low energies, it reduces to a
Lorentz-violating scalar-tensor gravity theory. The deviations with respect to
general relativity can be made weak by an appropriate choice of parameters.
