September 2025 marked the 110th anniversary of the birth of Academician, soil scientist and ecologist Gleb V. Dobrovol’sky. His research was not limited to the natural sciences. A significant part of his activity was scientific and educational work within the Scientific Council of the Russian Academy of Sciences for the Study and Protection of Cultural and Natural Heritage. From 1998 to 2013, he served as co-chair of the Council and led its natural heritage research. During this period, soil scientists were actively involved in the Council's work: seminars and conferences were organized, articles and monographs were published, and dissertations on soils and society were defended. But most importantly, it supported the research of scientists in line with the principles of natural-cultural synthesis. The approaches pioneered by G.V. Dobrovolsky further advanced the field of soils and society. This article examines the main areas of work of the Scientific Council of the Russian Academy of Sciences and its major achievements.

Brief information is given about several Russian microbiologists--naturalists whose names are found on the pages of V.I. Vernadsky’s diaries. Despite the variety of topics, their works always found hot reaction of V.I. Vernadsky. The knowledge of these materials helps one to understand the evolution of the scientists’ ideas, trends of the development of science.

The constantly extending list of humankind-produced environmentally toxic compounds currently includes pharmacological preparations. Among them, of potential relevance are neurotransmitters including such biogenic amines as norepinephrine, dopamine, serotonin, and histamine, as well as acetylcholine. These neurotransmitters were tested in the present work using such model organisms as the green microalgae Chlorella vulgaris Beijer, Scenedesmus quadricauda (Turp.) Breb. К-1149, and Haematococcus lacustris (= pluvialis) strains IPPAS H-239 and BM-1, as well as the cyanobacterium Limnospira platensis IPPAS B-256. It was established that all tested neurotransmitters significantly stimulate the growth of the cultures of microalgae at sufficiently low (micromolar) concentrations. In light of the results of this work, uncontrollable microalgal growth seems to be possible under the influence of trace amounts of neurotransmitters in natural and artificial water bodies, which might cause their eutrophication. All tested substances influenced the photosynthetic pigment content at micromolar (or submicromolar) concentrations, acetylcholine being a quasi-universal promoter of their biosynthesis that presumably stimulates the photosynthetic activity of the microalgae. The effects of the other tested substances varied depending on the microalgal species involved but predominantly resulted in promoting photosynthetic pigment biosynthesis. A biotechnological project aimed at stimulating the microalgal biomass yield by supplementing microalgal cultures with neurotransmitters seems to hold promise for producing drugs, food additives, or biofuel.

A brief analysis of modern interdisciplinary directions in science as the basis for its further development is given. The intense development of the theory of self-organization, synergetics, fractal theory, and the theory of complex systems and especially the modern development of nanoscience and nanotechnologies are noted. The commonality and difference of these scientific directions and their prospects are shown.
