🔷 تصویربرداری سرد برای نجات جان انسان‌ها؛ تحول در طراحی داروهای پیشرفته

🔹 دانشمندان دانشگاه ناتینگهام روشی پیشرفته برای بررسی ساختار نانوذرات لیپیدی توسعه دادند؛ روشی که می‌تواند دارورسانی را در درمان بسیاری از بیماری‌ها متحول سازد.

🔹 در پژوهشی که به‌تازگی در مجموعه مقالات توسعه روش‌های طیف‌سنجی جرمی نشریه نیچر منتشر شده است، تیمی از پژوهشگران به رهبری دانشمندان دانشکده داروسازی دانشگاه ناتینگهام موفق شدند با بهره‌گیری از روشی نوین موسوم به طیف‌سنجی جرمی برودتی، ساختار سطحی نانوذرات لیپیدی منجمد را به‌صورت لایه‌به‌لایه آشکار کنند. نانوذرات لیپیدی (Lipid Nanoparticles – LNPs) که شهرت جهانی خود را طی موفقیت واکسن‌های مبتنی بر RNA شرکت‌های مدرنا (Moderna) و فایزر-بیوان‌تک (Pfizer-BioNTech) در دوران همه‌گیری کرونا کسب کردند، اکنون به‌عنوان یکی از امیدبخش‌ترین ابزارهای دارورسانی نوین در...

How Does Bitcoin Work?

Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. “Once a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”

Telegram Q&A

Q: How does hottg.com work?

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.

Q: What is Telegram? What do I do here?

Telegram is a messaging app with a focus on speed and security, it’s super-fast, simple and free. You can use Telegram on all your devices at the same time — your messages sync seamlessly across any number of your phones, tablets or computers.

Telegram is for everyone who wants fast and reliable messaging and calls. Business users and small teams may like the large groups, usernames, desktop apps and powerful file sharing options.

Public groups can be joined by anyone and are powerful platforms for discussions and collecting feedback.In case you're more into pictures, Telegram has animated gif search, a state of the art photo editor, and an open sticker platform (find some cool stickers here or here). What's more, there is no need to worry about disk space on your device. With Telegram's cloud support and cache management options, Telegram can take up nearly zero space on your phone.

Q: How is Telegram different from WhatsApp?

Unlike WhatsApp, Telegram is a cloud-based messenger with seamless sync. As a result, you can access your messages from several devices at once, including tablets and computers, and share an unlimited number of photos, videos and files (doc, zip, mp3, etc.) of up to 2 GB each. And if you don't want to store all that data on your device, you can always keep it in the cloud.Thanks to our multi-data center infrastructure and encryption, Telegram is faster and way more secure. On top of that, Telegram is free and will stay free — no ads, no subscription fees, forever.

Q: Can I make calls via Telegram?
