Query: Diffeomorphic souls and disconnected moduli spaces of nonnegatively
  curved metrics   We give examples of open manifolds that carry infinitely many complete
metrics of nonnegative sectional curvature such that they all have the same
soul, and their isometry classes lie in different connected components of the
moduli space. All previously known examples of this kind have souls of
codimension one. In our examples the souls have codimensions three and two.
