Query: On the problem of synthesis of superheavy nuclei. A short historical
  review on first theoretical predictions and new experimental reality   It is shown that it is just Dubna that possesses the priority both in the
recent synthesis of a superheavy nucleus with charge Z = 114 (Flerov Laboratory
of Nuclear Reactions, JINR) and in its theoretical prediction (Bogoliubov
Laboratory of Theoretical Physics, JINR) made 33 years ago. Possible sizes of
the island of stability of superheavy nuclei are discussed.
