Borel and Haefliger asked in 1961 whether cycle classes on smooth projective complex varieties are smoothable, that is, belong to the subgroup generated by classes of smooth subvarieties. This was disproved for cycles of dimension greater than or equal their codimension. I will explain the proof of smoothability of cycles of dimension smaller than their codimension (joint work with Kollár).
