1. To the team of Russian chemists and materials scientists from the Institute of General and Inorganic Chemistry named after V.I. N.S. Kurnakov Russian Academy of Sciences, Russian University of Chemical Technology. DI. Mendeleev, Institute of Silicate Chemistry named after I.V. Grebenshchikov Russian Academy of Sciences and St. Petersburg Institute of Nuclear Physics named after B.P. Konstantinov managed to achieve high sensitivity of sensors for detecting toxic and flammable gases. To do this, they used platinum, which is considered an excellent catalyst for the oxidation of hydrogen, hydrocarbons and aromatics, which explains the increased sensory response to these gases.

2. Today, about 50% of Russian and 50-60% of the world's deposits belong to deposits, reserves from which are difficult to extract. Scientists from Perm Polytechnic University and Curtin University(Perth, Australia) have developed a technology to assess the potential of fractured oil reservoirs - natural ‘arteries’ through which hydrocarbons pass. The technique will be able to quickly and inexpensively determine the parameters of fractures for effective oil production from low-permeability formations.

3. Skoltech scientists used the Zhores supercomputer installed at the institute to investigate a new method of generating gamma-ray combs for nuclear and X-ray photonics and spectroscopy of new materials. Our idea is based on a method well known to specialists in the field of attosecond physics. It uses laser pulses with time-varying polarization(circular at the edges and linear at the center of the pulse) in order to limit the emission of harmonics to only that part of the pulse where the polarization is linear.

4. Doctors at Moscow State University have proposed the use of spironolactone for the treatment of coronavirus pneumonia and have shown its effectiveness in combination with dipyridamole. We are starting a clinical trial of a combination of spironolactone and dipyridamole for patients with complex coronavirus infection. At the same time, we expect a decrease in the severity of pulmonary fibrosis and pneumonia in patients.

5. The launch of the first radar Earth observation satellite Obzor-R is planned for next year, said Valery Zaichko, deputy director of the Roscosmos navigation space systems department. Earlier it was reported that the launch of Obzor-R by the Soyuz-2.1a carrier rocket from the Plesetsk cosmodrome is scheduled for the third quarter of 2021.
