دانشمندان MIT موفق به توسعه روشی شدند که با ترکیب نانوذرات و یک تست ساده ادرار، امکان تشخیص زودهنگام سرطان ریه را فراهم می‌کند.
🔹 چطور عمل می‌کند؟
1️⃣ استنشاق نانوذرات حاوی بارکدهای DNA 2️⃣ تغییر این نانوذرات در حضور آنزیم‌های توموری و انتقال آنها به ادرار 3️⃣ تشخیص آسان با یک نوار کاغذی ساده مشابه تست بارداری
💡این روش:
✔️ کمتر تهاجمی ✔️ مقرون‌به‌صرفه ✔️ مناسب برای مناطق با منابع محدود

The company maintains that it cannot act against individual or group chats, which are “private amongst their participants,” but it will respond to requests in relation to sticker sets, channels and bots which are publicly available. During the invasion of Ukraine, Pavel Durov has wrestled with this issue a lot more prominently than he has before. Channels like Donbass Insider and Bellum Acta, as reported by Foreign Policy, started pumping out pro-Russian propaganda as the invasion began. So much so that the Ukrainian National Security and Defense Council issued a statement labeling which accounts are Russian-backed. Ukrainian officials, in potential violation of the Geneva Convention, have shared imagery of dead and captured Russian soldiers on the platform. In a statement, the regulator said the search and seizure operation was carried out against seven individuals and one corporate entity at multiple locations in Ahmedabad and Bhavnagar in Gujarat, Neemuch in Madhya Pradesh, Delhi, and Mumbai. This provided opportunity to their linked entities to offload their shares at higher prices and make significant profits at the cost of unsuspecting retail investors. The message was not authentic, with the real Zelenskiy soon denying the claim on his official Telegram channel, but the incident highlighted a major problem: disinformation quickly spreads unchecked on the encrypted app. 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.
