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。 Guardian：Scientists crack what they say is the perfect way to boil an egg 科技日报：如何煮出熟度均匀的鸡蛋？

In recent times, Telegram has gained a lot of popularity because of the controversy over WhatsApp’s new privacy policy. In January 2021, Telegram was the most downloaded app worldwide and crossed 500 million monthly active users. And with so many active users on the app, people might get messages in bulk from a group or a channel that can be a little irritating. So to get rid of the same, you can mute groups, chats, and channels on Telegram just like WhatsApp. You can mute notifications for one hour, eight hours, or two days, or you can disable notifications forever.
Should I buy bitcoin?
“To the extent it is used I fear it’s often for illicit finance. It’s an extremely inefficient way of conducting transactions, and the amount of energy that’s consumed in processing those transactions is staggering,” the former Fed chairwoman said. Yellen’s comments have been cited as a reason for bitcoin’s recent losses. However, Yellen’s assessment of bitcoin as a inefficient medium of exchange is an important point and one that has already been raised in the past by bitcoin bulls. Using a volatile asset in exchange for goods and services makes little sense if the asset can tumble 10% in a day, or surge 80% over the course of a two months as bitcoin has done in 2021, critics argue. To put a finer point on it, over the past 12 months bitcoin has registered 8 corrections, defined as a decline from a recent peak of at least 10% but not more than 20%, and two bear markets, which are defined as falls of 20% or more, according to Dow Jones Market Data.
