Компания San-Etsu Metal из Японии разрабатывает новые виды латунных изделий без висмута. Причина — резкий рост цен на висмут (до 12 тыс. иен за кг) из-за экспортных ограничений Китая.

Telegram is certainly not the most secure messaging app on the market right now. Its security model requires users to place a great deal of trust in Telegram’s ability to protect user data. For some users, this may be good enough for now. For others, it may be wiser to move to a different platform for certain kinds of high-risk communications. Multiple pro-Kremlin media figures circulated the post's false claims, including prominent Russian journalist Vladimir Soloviev and the state-controlled Russian outlet RT, according to the DFR Lab's report.
