New monographs of the scholarly series ROSSICA. Russia and the West. Literary Connections and Contacts of the Litfact publishing house examine Russian-French and Soviet-American literary and cultural connections of the first half of the 20th century. Book by Alexandre Stroev is dedicated to the Russian writers (I. Bunin, Dm. Merezhkovsky, A. Bely, E. Zamyatin, M. Voloshin) in France, their literary and public reputation and the reception of their works. Galina Lapina considers American-Soviet contacts and joint projects (theatrical, cinematic, educational) of the 1930s and early 1940s. The heroes of her book are American writers, journalists, diplomats, artists, and students. Both monographs are based on archival documents, letters, memoirs, fictional texts, materials from the Soviet/Russian and foreign (French or American) press. The study of an impressive source array made it possible to reveal unexplored episodes in the life of Russian writers in France and unknown part of their legacy, to reconstruct the history of Soviet-American joint ventures in the fields of culture, education, literature, theater and cinema.

The 2019 coronavirus disease (COVID-19) outbreak has become global. The unprecedented socioeconomic impact of the pandemic has highlighted the need to improve existing diagnostic methods and develop new methods to control the spread of the disease. Traditional technologies such as quantitative real-time polymerase chain reaction (qRT-PCR) have been considered the gold standard for testing for COVID-19 since the SARS-CoV-2 genome sequence was published. However, they are time-consuming, labor-intensive and do not guarantee the absence of false results. Electrochemical biosensors present alternative approaches to detect viral nucleic acids or viral antigens. High sensitivity, relatively low cost of sensors and equipment, convenient management, rapid analysis, and suitability for miniaturization may contribute to the development of point-of-care (POC) testing for COVID-19. The review examines and critically discusses modern electrochemical biosensors for SARS-CoV-2 detection and related technologies.
