I review the results of a wide-range international collaboration. The empirical analysis of the interstellar matter and the early stages of the stellar formation takes place 8 years ago under the title mentioned project with Hungarian participation. We determine the physical parameters of more than 10 thousand interstellar clouds with an entirely new approach. A substantial portion of the clouds show the signs of star formation. The work resulted not only in publications but also new observing campaigns. I will select some news abut these campaigns, as well.
