Scientists from the Winogradsky Institute of Microbiology RAS, RUDN University, St. Petersburg State University and the Tyumen Scientific Centre SB RAS studied the microbial communities from several lakes of the Yamal Peninsula. It turned out that methanotrophs (bacteria that use methane as a source of energy) consume methane more actively in the deep mature lakes of the peninsula than in small thermokarst lakes. In this regard, methane emissions into the atmosphere from the surface of deep lakes are low, and only small (relatively younger thermokarst lakes with constitutional ground ice) can make a significant contribution to methane emissions in the north of Western Siberia. Thus, bacteria perform an important function for the climate balance — they reduce the emission of methane into the atmosphere.
RUDN University physicists have described the conditions for the most efficient operation of long mirror-based variant of cyclotron in the autoresonance mode. These data will bring better understanding of plasma processes in magnetic traps.
The World Legislative Congress of the International Federation of Translators (FIT-IFT) officially approved the membership of RUDN University.
Chemists from Russia and the USA have improved the method of creating bioactive indole-acetonitrile compounds. Previously, in the course of their synthesis, by-products were obtained — a new method allows them to be avoided. This increases the yield of the final product to 81%.
RUDN University doctors have identified genetic features that may affect the susceptibility to reoccurring stenosis (luminal renarrowing) after stent deployment. The results will help to determine the risk of restenosis and choose a personalized therapy more accurately.
RUDN chemists have created a reusable catalyst for the oxidation of sulfides for the synthesis of drugs, dyes and other compounds. It can “switch” the final product and provides “green” reaction conditions.
