Here, "one aim.several goals" background m.thod for boosting (activating) biom.terials by weak low frequency m.gnetic field for m.ny branches of biotechnology and m.dicine was presented. Our original m.thod allows us to activate for the one hand the growth and reproduction of stem.cells without any cancer transform.tions, with de novo expression of m.NA m.R gene, decreased apoptotic effects and in the required am.unt which could be the very im.ortant application in m.ny branches of cancer therapy with standard chem.therapy procedures and without any fear about possible stem.cells transform.tion into cancer cells. But for another hand it also could be the way for the biofuel production from.m.croalgae Chlorella vulgaris. Such biofuel could be produced quickly and in large volum.s, and biosafety waste products could use as a tool for rehabilitation of tsunam. or radiation-affected soils
