Russia Confirms Rare, Deadly ‘Black Fungus’ Infections Seen in India – Reports May 17, 2021 Experts stressed that mucormycosis does not spread from humans to humans and Russia is not at risk of a mass outbreak. Kirill Zykov / Moskva News Agency
Russia has registered cases of a rare and deadly fungal infection afflicting current and former coronavirus patients that has been on the rise in virus-stricken India, the pro-Kremlin Izvestia newspaper reported Monday.
Experts interviewed by the publication stressed that mucormycosis, which Indian doctors have dubbed “black fungus” due to its dark pigmentation, does not spread from humans to humans and Russia is not at risk of a mass outbreak. The infection, which has a 50% mortality rate, typically starts in the nose before spreading to the eyes and brain.

Exposure to light is compulsory for photosynthetic organisms for the conversion of inorganic compounds into organic ones. However, if there is too much solar energy, the photosystems and other cell components could be damaged. Thanks to special protective proteins, the overexcitation is converted into heat - in the process called non-photochemical quenching. The object of the published study, OCP, was one of such defenders. It was first isolated in 1981 from representatives of the ancient group of photosynthetic bacteria, ?yanobacteria. OCP comprises two domains forming a cavity, in which a carotenoid pigment is embedded. When light is absorbed by the carotenoid molecule, OCP can change from an inactive orange to an active red form. This process is multi-stage and follows a complex hierarchy of events. We showed the asynchrony of these changes in previous work, but the mechanism of the very first stage of OCP activation, associated with the breakage of hy
Stan Yurchenko: The World Will Give Up the Mega-Metropolis in the Next Hundred Years
Economist and mathematician Stanislav “Stan” Yurchenko believes that the centuries-old urge of humankind towards urbanization is living out its last decades. In the near future, people will take earnest thought that there is no need to stay crowded in huge cities. Besides, it is dangerous.
“The vulnerability of a mega-metropolis is one of the key lessons taught to us by the COVID pandemic,” says Stan Yurchenko. “The crowds in public transportation, on the street, and in supermarkets have become the key factor affecting the virus spread. Yet, at the same time, we realized that we no longer need human resources to be centralized.”

Young scientists of Tomsk Polytechnic University as a part of the team of Arctic researchers have studied pore waters in three areas of methane release on the surface. They first managed to define in details the composition of pore waters in the cold methane seeps of the Eastern Arctic seas. The research findings are published in the
Water academic journal.
The research was based on the samples obtained during the Arctic expedition aboard the research vessel Akademik Mstislav Keldysh in 2019. The scientists and students from 12 scientific institutions, including Tomsk Polytechnic University, Moscow Institute of Physics and Technology, Lomonosov Moscow State University, the Research Center of Biotechnology of the Russian Academy of Sciences, the Vernadsky Institute of Geochemistry and Analytical Chemistry of the Russian Academy of Sciences, the Zhirmunsky National Scientific Center of Marine Biology of the Far Eastern Branch of the Russian Academy of Sciences and others
