В рамках нашей рубрики «Картинка дня» мы продолжаем знакомить вас с победителями конкурса Nikon Small World. Среди работ, удостоенных почетного упоминания жюри (Honorable Mention) — вот эта прекрасная фоторабота, на которой мы видим сосуд головного мозга, окруженный астроцитами в тонком срезе головного мозга человека. Сосуды и астроциты — это одни из основных элементов такого замечательного механизма, который называется гемато-энцефалический барьер.

One thing that Telegram now offers to all users is the ability to “disappear” messages or set remote deletion deadlines. That enables users to have much more control over how long people can access what you’re sending them. Given that Russian law enforcement officials are reportedly (via Insider) stopping people in the street and demanding to read their text messages, this could be vital to protect individuals from reprisals. "He has to start being more proactive and to find a real solution to this situation, not stay in standby without interfering. It's a very irresponsible position from the owner of Telegram," she said. Telegram does offer end-to-end encrypted communications through Secret Chats, but this is not the default setting. Standard conversations use the MTProto method, enabling server-client encryption but with them stored on the server for ease-of-access. This makes using Telegram across multiple devices simple, but also means that the regular Telegram chats you’re having with folks are not as secure as you may believe. "Russians are really disconnected from the reality of what happening to their country," Andrey said. "So Telegram has become essential for understanding what's going on to the Russian-speaking world." Soloviev also promoted the channel in a post he shared on his own Telegram, which has 580,000 followers. The post recommended his viewers subscribe to "War on Fakes" in a time of fake news.
