The Nuts and Bolts of Brane Resolution
  We construct various non-singular p-branes on higher-dimensional generalizations of Taub-NUT and Taub-BOLT instantons. Among other solutions, these include S^1-wrapped D3-branes and M5-branes, as well as deformed M2-branes. The resulting geometries smoothly interpolate between product spaces which include Minkowski elements of different dimensionality. The new solutions do not preserve any supersymmetry.
