💢 میکروبی که در مواجهه با تشعشعات مرگبار، می‌خندد!
🦠باکتری Deinococcus radiodurans که به عنوان Conan the Bacterium هم شناخته می‌شود، یکی از مقاوم‌ترین موجودات طبیعی است که قادر است در سطوح تابش هزاران بار بالاتر از آنچه که یک انسان را می‌کشد، زنده بماند.
🔍دانشمندان سرانجام راز مولکولی پشت این مقاومت را کشف کرده‌اند. این کشف می‌تواند راه را برای فناوری‌های نجات‌دهنده زندگی، از اکتشافات فضایی تا درمان‌های پزشکی هموار کند.

Individual messages can be fully encrypted. But the user has to turn on that function. It's not automatic, as it is on Signal and WhatsApp. But Telegram says people want to keep their chat history when they get a new phone, and they like having a data backup that will sync their chats across multiple devices. And that is why they let people choose whether they want their messages to be encrypted or not. When not turned on, though, chats are stored on Telegram's services, which are scattered throughout the world. But it has "disclosed 0 bytes of user data to third parties, including governments," Telegram states on its website. Telegram was co-founded by Pavel and Nikolai Durov, the brothers who had previously created VKontakte. VK is Russia’s equivalent of Facebook, a social network used for public and private messaging, audio and video sharing as well as online gaming. In January, SimpleWeb reported that VK was Russia’s fourth most-visited website, after Yandex, YouTube and Google’s Russian-language homepage. In 2016, Forbes’ Michael Solomon described Pavel Durov (pictured, below) as the “Mark Zuckerberg of Russia.” Some people used the platform to organize ahead of the storming of the U.S. Capitol in January 2021, and last month Senator Mark Warner sent a letter to Durov urging him to curb Russian information operations on Telegram. The Securities and Exchange Board of India (Sebi) had carried out a similar exercise in 2017 in a matter related to circulation of messages through WhatsApp.
