💢 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.

Given the pro-privacy stance of the platform, it’s taken as a given that it’ll be used for a number of reasons, not all of them good. And Telegram has been attached to a fair few scandals related to terrorism, sexual exploitation and crime. Back in 2015, Vox described Telegram as “ISIS’ app of choice,” saying that the platform’s real use is the ability to use channels to distribute material to large groups at once. Telegram has acted to remove public channels affiliated with terrorism, but Pavel Durov reiterated that he had no business snooping on private conversations. Oleksandra Matviichuk, a Kyiv-based lawyer and head of the Center for Civil Liberties, called Durov’s position "very weak," and urged concrete improvements. What distinguishes the app from competitors is its use of what's known as channels: Public or private feeds of photos and videos that can be set up by one person or an organization. The channels have become popular with on-the-ground journalists, aid workers and Ukrainian President Volodymyr Zelenskyy, who broadcasts on a Telegram channel. The channels can be followed by an unlimited number of people. Unlike Facebook, Twitter and other popular social networks, there is no advertising on Telegram and the flow of information is not driven by an algorithm. In 2018, Russia banned Telegram although it reversed the prohibition two years later. Under the Sebi Act, the regulator has the power to carry out search and seizure of books, registers, documents including electronics and digital devices from any person associated with the securities market.
