美国联邦机构工作的科学家失去了对 Springer Nature 旗下知名期刊的访问权限。NASA、美国农业部、能源部以及国立卫生研究院 (NIH)等机构都终止了对 Springer Nature 旗下期刊的订阅合同。美国卫生与公众服务部 (HHS) 首席发言人 Andrew Nixon 称这些期刊都是垃圾科学。美国反疫苗的卫生部长 Robert F. Kennedy Jr.此前表示要停止在 Lancet、New England Journal of Medicine、JAMA 等期刊上发表论文，因为它们都腐化了，变成了制药行业宣传的载体。制药行业显然是疫苗的支持者。他表示除非相关期刊做出改变，否则美国联邦机构将禁止 NIH 科学家在这些期刊上发表论文。

From the Files app, scroll down to Internal storage, and tap on WhatsApp. Once you’re there, go to Media and then WhatsApp Stickers. Don’t be surprised if you find a large number of files in that folder—it holds your personal collection of stickers and every one you’ve ever received. Even the bad ones.Tap the three dots in the top right corner of your screen to Select all. If you want to trim the fat and grab only the best of the best, this is the perfect time to do so: choose the ones you want to export by long-pressing one file to activate selection mode, and then tapping on the rest. Once you’re done, hit the Share button (that “less than”-like symbol at the top of your screen). If you have a big collection—more than 500 stickers, for example—it’s possible that nothing will happen when you tap the Share button. Be patient—your phone’s just struggling with a heavy load.On the menu that pops from the bottom of the screen, choose Telegram, and then select the chat named Saved messages. This is a chat only you can see, and it will serve as your sticker bank. Unlike WhatsApp, Telegram doesn’t store your favorite stickers in a quick-access reservoir right beside the typing field, but you’ll be able to snatch them out of your Saved messages chat and forward them to any of your Telegram contacts. This also means you won’t have a quick way to save incoming stickers like you did on WhatsApp, so you’ll have to forward them from one chat to the other.
What is Telegram?
Telegram’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.
