پژوهشگران دانشگاه کالج لندن و مؤسسه فرانسیس کریک با استفاده از فناوری پیشرفته‌ی میکروسکوپی با ورقه نور، توانستند فرآیند شکل‌گیری قلب در جنین موش را با دقتی بی‌نظیر و به‌صورت سه‌بعدی تماشا کنند.
‌
آن‌ها با علامت‌گذاری سلول‌ها با نشانگرهای فلورسنت و تصویربرداری هر دو دقیقه به مدت ۴۱ ساعت، تایم‌لپسی خیره‌کننده تهیه کردند که نشان می‌دهد چگونه سلول‌ها از حالت پراکنده و بی‌نظم، به‌سوی ساختار یک قلب تپنده سازمان می‌یابند.
‌
یافته‌های این مطالعه نشان می‌دهد که سلول‌های قلبی، بسیار زودتر از تصورات پیشین، مسیر و نقش خود را «می‌دانند» و به‌صورت هدفمند حرکت می‌کنند. برخلاف تصور رایج که این فرآیند را آشوبناک می‌دانست، پژوهشگران دریافتند که نظم پنهانی بر آن حاکم است. این کشف می‌تواند درک ما از شکل‌گیری قلب را به‌طور بنیادین تغییر دهد و در آینده مسیر درمان‌های نوین برای نقص‌های مادرزادی قلب را هموار کند.

Look for Channels Online

You guessed it – the internet is your friend. A good place to start looking for Telegram channels is Reddit. This is one of the biggest sites on the internet, with millions of communities, including those from Telegram.Then, you can search one of the many dedicated websites for Telegram channel searching. One of them is telegram-group.com. This website has many categories and a really simple user interface. Another great site is telegram channels.me. It has even more channels than the previous one, and an even better user experience.These are just some of the many available websites. You can look them up online if you’re not satisfied with these two. All of these sites list only public channels. If you want to join a private channel, you’ll have to ask one of its members to invite you.

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.

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.
