Multiple Uses of the QCD Instantons

In spite of very general title, this is not a mini-review on instantons, but a sum of two unrelated new developments. The first deals with the pion and nucleon formfactors which were found to be calculable in a simple single-instanton approximation. The second is summary of several recent papers on production of the topological sphaleron-type gluomagnetic clusters in high energy reactions, which clarified their properties and production cross section. The paper ends with some estimates claiming that the latter process can be important for heavy ion collisions at RHIC energies.
