Query: D-branes and cosmic structure   We outline the embedding of the vector curvaton scenario as a promising
mechanism to generate statistical anisotropy within Type IIB string theory,
where the vector field on a single D-brane plays the role of the vector
curvaton. We first consider a toy model in the context of open string
inflation, and then begin to construct a concrete model in the context of
closed string inflation.
