Scientists Discover One of the Longest-Lasting Cases of COVID-19
An international team, including researchers from HSE University, examined an unusual SARS-CoV-2 sample obtained from an HIV-positive patient. Genetic analysis revealed multiple mutations and showed that the virus had been evolving inside the patient’s body for two years. This finding supports the theory that the virus can persist in individuals for years, gradually accumulate mutations, and eventually spill back into the population. The study's findings have been published in Frontiers in Cellular and Infection Microbiology.
HSE Researchers Develop New Method for Analysing Genetic Admixture of Populations
Researchers of the HSE International Laboratory of Statistical and Computational Genomics together with their international colleagues have proposed a new statistical method for analysing population admixture that makes it possible to determine the time and number of migration waves more accurately. The history of Colombians and Mexicans (descendants of Native Americans, Spaniards and Africans) features two episodes of admixture that occurred about 350 and 200 years ago for Mexicans and 400 and 100 years ago for Colombians. The results were published in the Plos Genetics journal.
Nature Communications Journal Publishes a Study by Russian Scholars Involving HSE MIEM Students
Biologists and mathematicians from HSE University, Skoltech and the RAS Kharkevich Institute have studied the spread of COVID-19 in Russia. The main part of the study was completed in late June, but until October, the team was working with data following the reviewers’ recommendations. The paper was published on January 28, 2021 in the journal Nature Communications. MIEM students spoke about their contribution to the research.
