Russian Scientists Discover Way to Increase Effectiveness of COVID-19 Vaccines
Scientists from the Institute of Bioorganic Chemistry of the Russian Academy of Sciences, in collaboration with the Research Institute of Systems Biology and Medicine, have discovered a way to improve COVID-19 vaccines by enhancing the body's immune response.
The researchers focused their study on the S protein receptors of five coronavirus strains, including the Wuhan-Hu-1, Alpha, Delta, Gamma, and Omicron strains. The results of the study showed that the S protein in the Omicron strain degrades differently than in other strains, affecting the immune response.
Anna Kudyryaeva, the project supervisor, explained that this discovery helps understand the mechanisms of interaction between the virus and the immune system and provides guidance for the development of a new generation of vaccines that enhance the effectiveness of the immune response and provide better protection against new coronavirus variants.

NASA: "Cosmic Monster" Swallows Star, Triggering Massive Explosion
Washington - Saba: NASA has captured a stunning image of a rare black hole, believed to be of intermediate mass, tearing apart a star and causing a cosmic explosion. This event is considered strong evidence of the "missing link" in the evolution of black holes. Scientists observed the black hole, known as HLX-1, located 450 million light-years from Earth at the outer edge of the galaxy NGC 6099, according to Live Science. An animation created by the scientists shows the moment the black hole rips apart the star, triggering a deafening explosion. For his part, Dr. Yi-Chi Chang, head of the research team from National Tsing Hua University in Taiwan, explained that "this discovery is like finding a 'missing link' that connects small black holes resulting from collapsing stars and the supermassive black holes that dominate galaxies." "It gives us a rare glimpse into the evolution of these cosmic monsters," he said. Intermediate-mass black holes are mysterious and difficult to observe, as they may resemble small black hole clusters or hide behind nearby star clusters. Scientists caution, however, that HLX-1 needs further study to confirm its nature, as the flashing may be caused by other phenomena, such as fluctuations in the accretion disk surrounding the black hole. As a new generation of advanced telescopes comes online, astronomers expect to discover more of these mysterious black holes, enhancing our understanding of the universe and the evolution of these massive cosmic phenomena.

UK Health Security Agency: Spread of new COVID variant 'Stratos'
London – SABA: The UK Health Security Agency (UKHSA) has announced the rapid spread of a new COVID-19 variant known as 'Stratos', which has now become a notable proportion of coronavirus infections across the United Kingdom. In a statement issued Thursday, the agency said that recent genomic analyses showed that the XFG strain and its sub-lineages are now the most prevalent in sequenced samples. According to official data, the XFG and XFG.3 subvariants accounted for approximately 40% of total COVID-19 infections by the end of June—a significant increase from just 10% in May. 'Stratos' is a recombinant subvariant of the highly contagious Omicron lineage, labeled as a so-called 'Frankenstein variant' due to its hybrid nature. It emerged from a genetic fusion between two highly transmissible subvariants: LF.7 and LP.8.1.2, resulting in this new hybrid strain. Health experts have warned that Stratos could be more virulent and transmissible than previous strains, due to its mutations that enhance immune evasion—whether from prior infections or vaccinations.

Russian Scientists Develop Coating to Protect Aircraft Engines
Moscow - (Saba): Scientists from the Ural Federal University and the Institute of Electrophysics of the Ural Branch of the Russian Academy of Sciences have developed an innovative coating made of silicon, aluminum, carbon, and nitrogen that can protect aircraft engine components from oxidation at extreme temperatures. The development combines low synthesis temperatures of up to 400°C, a high deposition rate, and high hardness. All of this will reduce the cost of manufacturing parts and extend the life of civil aircraft and helicopter engines, according to the Scientific Russia portal. The study, supported by the Russian Science Foundation and published in the journal "Ceramics," features high oxidation resistance at high temperatures. This means that in an oxygen-containing environment, when heated, a barrier layer is formed due to the aluminum content, preventing oxygen from penetrating deep into the protected material. The difficulty of obtaining such multicomponent functional coatings is due to the need to create a dense structure with the required chemical elements, according to Andrey Menshakov, a senior researcher at the Laboratory of Photovoltaic Materials at the Ural Federal University and the Institute of Electrophysics of the Ural Branch of the Russian Academy of Sciences. The coating was obtained using a hybrid technology combining aluminum evaporation and plasma activation of organosilicon. Experiments have shown that the new material has a hardness of up to 31 gigapascals (comparable to diamond-like coatings) and a dense, defect-free structure. By comparison, conventional methods for creating such protective films on the surface of turbine elements require temperatures above 1,000 degrees Celsius and often lead to the formation of various defects. Over two years, the scientists conducted more than ten series of tests, resulting in the creation of several hundred samples. According to the researchers, choosing the optimal conditions made it possible to achieve the formation of a dense nanostructured coating with the desired chemical composition, ensuring the new composite's high mechanical properties. Andrey Menshakov added, "We were able to vary the compounding conditions over a wide range, and the process itself is carried out at relatively low temperatures (100, 200, 400 degrees Celsius). This allows the application of protective coatings not only to steel and titanium products, but also to low-melting materials such as polycarbonate." We also face no obvious restrictions on scaling the facility for industrial production; in this case, everything depends directly on the task at hand. Plans include testing the coating on real components of gas turbines and jet engines, as well as adapting the technology for other industries. Whatsapp Telegram Email Print more of (International)
