High-energy neutrino astrophysics is developing intensively, and new and exciting results have been obtained in the last two years. Among them are the confirmation of the exist„ence of a diffuse flux of astrophysical neutrinos by the new independent Baikal-GVD experiment, the discovery of neutrino emission in our Galaxy, new confirmations of the connection of some astrophysical neutrinos to blazars, and much more. This brief review, based on the author's presentation at the session of the RAS Physical Science Division, "Gamma quanta and neutrinos from space: what we can see now and what we need to see more," summarizes the results obtained since the publication of the review [Phys. Usp. 64 1261 (2021)] and can be considered a companion to it.
