Scientists Reveal the Water Column of the Yamal Lakes Can Be a Microbial Filter

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.

The new protocol will allow to obtain bioactive compounds bypassing by-products

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 scientists proposed using satellite images to assess the state of chernozems

RUDN scientists have traced the changes that have occurred in the chernozems of the Belgorod region over the past 35 years. During soil degradation, they often change color, and this allowed specialists to assess their condition from satellite images. This method will help to quickly identify the deterioration of the soil and regulate its use in order to increase the efficiency of cultivation.

RUDN University Engineers Propose a New Approach for Accounting Plastic Anisotropy in the Theoretical Description of Metal Forming Processes

RUDN University engineers have shown that theoretical calculations traditionally used to describe the compression of metal work pieces, do not take into account an important property of materials. Scientists have proposed a new approach that considered the missing property and showed that the final result in this case changes by 15-20%.
