The paper scrutinizes the role of internal geodynamics of Earth, technogenesis and global climate changes in the context of aggravating hazardous natural processes on the Earth. Intensification of geohazards due to a number of techno-natural factors requires the elaboration of a new strategy of modern civilization development based on keeping the balance between the human economic activity and the environment protection. The strategy of living with natural disasters based on the assessment of natural risks of socioeconomic losses is discussed. The procedure of natural risk assessment is exemplified by the map of complex individual natural risk for population of the Russian Federation with the account of earthquakes, floods, hurricanes, snow avalanches, landslides, and mudflows. The necessity of developing the scientifically grounded policy of human technogenic activity based on the principle of technogenesisenvironment coevolution is reported. KEYWORDS: Technogenesis; global climate change; internal geodynamics of the Earth; hazardous technonatural processes; risk assessment.
Genetically identical organisms under the same conditions usually have differences in the level of expression of the same genes. This phenomenon is called genetic noise, and it is characteristic of all organisms. In this paper, we studied the stochasticity of gene expression in Mycoplasma gallisepticum at the level of single cells using fluorescence microscopy. The results show that M. gallisepticum demonstrates high level of variations in gene expression: even in case of strong promoters and ribosome-binding sites, some cells demonstrate negligible expression level. Such a high stochasticity in gene expression may have significant impact on the life of this reduced bacterium.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
