Scientists of the Skolkovo Institute of Science and Technology and Saratov State University named after N. G. Chernyshevsky have developed a new, cost-effective method for visualizing blood flow in the vessels of the brain. The accuracy of the method is so high that it allows reconstructing the vascular map by the movement of individual red blood cells, and without the use of toxic dyes and expensive genetic engineering.

Despite the fact that it is just a fragment of rock, a strange cosmic body has attracted the attention of scientists with its unusual proximity to the Sun — they do not know how it got there.
Non-coding RNA in the cell enters some important organelles, regulates protein synthesis, accelerates individual reactions and participates in other biologically important processes. Often, the functioning of non-coding RNAs is ensured by stable interactions of nucleotides of one or more RNA molecules. A bioinformatician from MIPT and the Institute of Mathematical Problems of Biology of the Russian Academy of Sciences described the known structures of non-coding RNAs associated with adenine.
Libido. This concept of psychoanalysis was developed by grandfather Freud to explain the sacred sexual energy of a person. We offer you to learn more about your sexual inclinations by the method of the author of graphic tests Zlata Koroleva.
Duke University scientists have estimated the likelihood of pandemics in the future. The Mandatory Medical Insurance Fund of the Russian Federation estimated the state's costs for combating the pandemic. According to the US Centers for Disease Control and Prevention, the effectiveness of vaccines has fallen to 66% due to the spread of the delta strain. The International Vaccine Institute (South Korea) has announced the start of the second phase of clinical trials of a vaccine against the chikungunya virus in Costa Rica.
