New record and phylogenetic assessment of (Braun, 1902) (Digenea: Psilostomidae), a parasite of Eurasian Coot Linnaeus, 1758 (Aves: Rallidae).

Phylogenetic studies of aberrant species are of considerable scientific interest because their taxonomic rank in traditional systems based on morphological characters is not infrequently overestimated. (Braun, ) is one of the few psilostomid digeneans devoid of the pharynx. This is considered a sufficient basis for assigning it and similar species to the subfamily Apopharynginae.

[Health risks of school-age children with distance learning in the first months of the spread of COVID-19].

According to the results of a sociological survey of 10,237 parents of schoolchildren during the period of emergency transfer of students to distance learning in the initial period of the spread of coronavirus infection, a low provision of children with technical teaching aids was revealed: only 18% of children had a stationary computer at home, 42% of children had a basic gadget available. available for training, there was a smartphone. At the same time, it was determined that children also use gadgets for a considerable time for personal purposes (entertainment, games): according to 17% of parents, 3-4 hours, and 8% of parents answered - more than 5 hours a day.
