RUDN University researchers have shown that technogenic toxicants in the ecosystem are distributed unevenly. The reason for this is that they come from the source in “portions”. Further, an active interaction of technogenic and natural factors begins: soils temporarily deposit pollution and create conditions for the transformation of toxicants. Further, the buffer role of the roots is switched on, which do not allow some pollutants to pass through. From a practical point of view, these data are important for optimizing the traffic load in urban ecosystems and developing technologies for cleaning soils in the city.

RUDN University epidemiologists have reconstructed the history of hepatitis B and D viruses evolution in Yakutia (Russia). The investigation has established the course of evolution over the past fifteen hundred years. It turned out that a silent epidemic of hepatitis D continues in the region, and measures must be taken to stop it.

Scientists from the Nikol'skii Mathematical Institute of RUDN University built a mathematical model that describes the self-sustaining propagation of virus concentration waves – autowaves – in a tissue or cell culture, taking into account their competition for resources, that is the infected cells. The authors applied the constructed model to study variants of the new coronavirus, Delta and Omicron. It turned out that the autowave with the higher speed of spatial propagation wins, while the slow autowave dies. The studied processes relate to the competition and evolution of viral strains in the upper respiratory tract in vivo. In addition, the proposed approaches can be used when creating new methods for studying viruses in vitro.

RUDN agronomists have studied the microbial community of water and soil in the Arctic. In recent years, this region has been increasingly polluted with oil products. Some of the detected microorganisms are able to “digest” oil hydrocarbons that are dangerous for the environment. Perhaps in the future they will help clean up the region.

Scientists from the Immanuel Kant Baltic Federal University showed with the help of mathematical calculation that the only way to prevent the falling of the kilometer-long asteroids on the Earth is to trigger a powerful thermonuclear explosion on their surface, that enables to correct their trajectory or to fracture the dangerous object into smaller pieces. Asteroids of such size may collide with the Earth once in a 500 thousand of years and cause the partial destruction of human civilization. This work helps to assess the technical applicability of various methods of struggling with potentially dangerous cosmic bodies
