1. TsAGI scientists have modified the drones with a pushing propeller. One of the new vectors in the development of aircraft construction is the development of aircraft-type drones. They are used for monitoring the earth's surface and various objects. Scientists of the Central Aerohydrodynamic Institute named after Professor N.E. Zhukovsky. The use of a straightening device will make it possible to lighten the weight of the structure and reduce the required engine power, which in turn will reduce fuel consumption or battery discharge.

2. The economic efficiency from the introduction of the digital Arctic logistics management system ‘Kapitan’ for 2019-2020 amounted to 0.9 billion rubles. Thanks to the application of this system, the unit costs of Gazprom Neft for the export of 1 ton of Arctic oil decreased by 12% in comparison with the years before the use of the Captain. This effect was achieved by optimizing the operating costs of tankers by choosing the best routes, saving fuel, reducing the cost of icebreaker assistance, as well as reducing downtime and maximizing oil export.

3. Employees of the Cluster Catalysis Laboratory at St. Petersburg State University synthesized polymers from biomass processing products. The peculiarity of the new materials lies in their ease of recycling. The main component of these polymers is terpenols.

4. Scientists from Russia and Germany studied the molecular composition of the insoluble organic matter of two meteorites(carbonaceous chondrites), Murchison and Allende, in order to understand their origin. Ultra-high resolution mass spectrometry has shown a huge variety of meteorite chemistry and revealed unexpected similarities between meteorites belonging to different groups.

5. Russian engineers are working on promising vehicles with a carrying capacity of up to 200 tons. This is significantly higher than the performance of the ‘lunar’ super-heavy rocket known as the Enisei. The development of such media will require very large expenditures from Russia, so they are now considering the issue of implementing projects together with other countries.
