In the run-up to Russian Science Day, which is celebrated annually on February 8th, the book service Litres has analyzed the demand for non-fiction literature about modern science. Based on the results of 2025, revenue (across all monetization models) from the sales of books on this topic increased by 41% compared to 2024.

In the top 10 most popular books in this category, six spots were occupied by works from Russian authors.

In fifth place is the study "Artificial Intelligence in Russia. Technologies and Markets," prepared by a team of authors from the HSE University's Institute for Statistical Studies and Economics of Knowledge. Next is the audiobook "The Biotech Summa: A Guide to Combating Myths about the Genetic Modification of Plants, Animals, and Humans" by Alexander Panchin, a Candidate of Biological Sciences, as well as the electronic version of this publication. In eighth place is the book "Hyperspace: A Scientific Odyssey Through Parallel Universes, Time Warps, and the 10th Dimension" by American theoretical physicist Michio Kaku. In ninth is "Astrophysics.
