In recent years, evidence of intrinsic nano-scale inhomogeneities in manganites has been gathered by dozens of experimental groups. Theoretical developments independently arrived to similar conclusions and provided a tentative unifying framework to understand the colossal magnetoresistance phenomenon as caused by these inhomogeneities. The status of this active field of research will be reviewed [1]. The general aspects of the problem will be discussed, including extensions to cuprates in the underdoped regime where coexisting superconducting and antiferromagnetic clusters could be possible [2].
