科学家声称找到煮鸡蛋的完美方法
#科学

传统煮鸡蛋的方法有两种:在 100 摄氏度的沸水中硬煮,但这会导致蛋黄完全凝固;通过真空低温烹调,在 60 到 70 摄氏度下慢慢炖煮一小时,但这会让蛋白不够熟。科学家现在报告了一种被称为“周期性烹饪”的新方法。它不仅让每一颗煮鸡蛋都能达到完美的均匀熟度,还能提升其营养成分。科学家利用计算流体动力学软件模拟出了这种全新的煮蛋过程:将鸡蛋在 100 摄氏度的沸水和 30 摄氏度的冷水中交替浸泡,每两分钟转移一次,总共持续 32 分钟。在这段时间里,蛋白逐渐变得细腻而富有弹性,蛋黄则保持了奶油般的柔软质感。经过处理后蛋黄中的多酚含量显著增加,这是一种被认为对健康非常有益的微量营养素。

Telegram Gives Up On Crypto Blockchain Project

Durov said on his Telegram channel today that the two and a half year blockchain and crypto project has been put to sleep. Ironically, after leaving Russia because the government wanted his encryption keys to his social media firm, Durov’s cryptocurrency idea lost steam because of a U.S. court. “The technology we created allowed for an open, free, decentralized exchange of value and ideas. TON had the potential to revolutionize how people store and transfer funds and information,” he wrote on his channel. “Unfortunately, a U.S. court stopped TON from happening.”

Export WhatsApp stickers to Telegram on Android

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.
