This article describes the first half of the UN Decade of Ocean Science for Sustainable Development (2021- 2030). It presents the background to the proclamation of the Decade and the development of its Implementation Plan. The results of the first half of the Decade, including the Russian Federation's contribution, are presented. The limited participation of Russian scientists and specialists in the Decade is noted.

This article presents conceptual approaches to the category of "well-being", which is considered as an alternative to other measures of social progress and economic growth. To this end, a review of current research by domestic and international authors on this topic is conducted, presenting their approaches to the essence of well-being, classified by types and subtypes. The theoretical review is based on all sources of scientific literature to which the authors had access (eLIBRARY.RU; scholar.google.ru; the Elsevier website), where the concept under study (well-being, types of well-being, approaches to assessing well-being) appears, specifically in terms of references in the text of the work or in the definition itself of the determinants of this phenomenon. The article systematizes the types and approaches to assessing well-being, demonstrating the category's multidimensionality (measured using both statistical and sociological indicators, using various scales, indices, and ratings), its multifaceted nature (the subject field of well-being assessments is very broad), and its multilevel nature (measurements extend to different levels, from personal well-being to the territorial level). The study assessed the socio-ecological-economic well-being of Russian regions using a multiplicative model based on A. Sen's abbreviated well-being function.

The paper examines the high environmental efficiency of renovating used technical products, which allows for a significant reduction in the consumption of natural resources and a decrease in environmental stress on the planet. Annually, over 10% of complex technical products are withdrawn from circulation worldwide after their service life due to wear of parts, amounting to no more than 0.1 - 0.5% of their weight, while the inner layers of the material in most products retain their original properties. Consequently, less than 1% of the resources invested in their creation is actually used, and the environmental pollution from their manufacturing is 100-150 times greater than the products' own weight. By removing the outer, defective material layer and applying a new one, then machining it to nominal specifications, the item is ready for use again. Renovating used products instead of manufacturing identical new ones leads to saving over 95% of all resources initially invested, a tenfold reduction in environmental pollution at minimal cost, and a reduction in the overall exploitation of non- renewable natural resources. However, this crucial scientific and technical direction for the ecologization of the technosphere is currently receiving no attention from industrial, consumer, governmental, scientific, or educational sectors.

Bibliometric networks of scientists are defined by the relationships between publications and/or their authors, implemented on the basis of lists of co-authors and bibliographic lists. Accordingly, considering scientific journals as a set of articles published in them over a certain period of time, we can talk about bibliometric networks of journals. The corresponding graph-theoretical models, called bibliometric graphs, are often used as mathematical models of bibliometric networks. The paper proposes an approach to the analysis of a network of journals using a new type of bibliometric graph, the graph of journal intersections, based on the binary operation of set intersection. The approach is demonstrated using a relatively small example of a real network of journals, data about which is contained in the information system of the All-Russian portal Math-Net.Ru. These are 63 journals from 2008-2021 that meet certain requirements and contain almost 69,000 articles by 54,000 authors.

One of the key social and medical problems in the Donetsk People's Republic (DPR) is the rising incidence of malignant neoplasms. Cancer is the second leading cause of death (19.3%). The history of the oncology service in Donbass dates back to 1943. Then, immediately after the liberation of Stalino (now Donetsk), the X-ray station and oncology hospital began to be reopened. Over the decades, the service has come a long way - from a small dispensary to a major Republican Oncology Center, which today bears the name of the founder of the oncology school and service in Donbass, the renowned surgeon and academician of the National Academy of Medical Sciences of Ukraine, G.V. Bondar. The oncocardiology service of the DPR continues to develop, providing high-tech medical care to the population. This symbiosis of science and practice not only improves the quality of life for patients but also strengthens the region's position in the healthcare system of the Russian Federation.

This article examines the results of the VI All-Russian Demographic Forum with international participation (December 2025), held with the support of the Scientific Council of the Russian Academy of Sciences "Demographic Development and Demographic Policy of the Russian Federation". It outlines the role of the Scientific Council of the Russian Academy of Sciences in implementing priority areas of state demographic policy aimed at supporting families, fertility, and self-preservation behavior. Abstracts of plenary reports by RAS members are presented, highlighting the social factors in reproductive behavior, the nature of scenario modeling of long-term demographic processes in Russia, and the specifics of corporate programs for men's health and active longevity.
