Quantum gravity stability of isotropy in homogeneous cosmology
  It has been shown that anisotropy of homogeneous spacetime described by the
general Kasner metric can be damped by quantum fluctuations coming from
perturbative quantum gravity in one-loop approximation. Also, a formal
argument, not limited to one-loop approximation, is put forward in favor of
stability of isotropy in the exactly isotropic case.
