In 1992, the Science Society of Galicia (SCG) decided to begin publishing a multidisciplinary journal open to all areas of Science and Technology.

The number “00” of “Mol” was published in January 1993, and this publication continued in the following years. From 2011 the journal was internationalized, publishing articles in Spanish and English. In 2015 began the renewal of the Editorial Board with the incorporation of foreign scientists and in 2016 the publication underwent a new remodeling, separating the scientific and technological content (Mol) of the information on the SCG (Boletín SCG, in Spanish).
