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 general, many financial experts support their clients’ desire to buy cryptocurrency, but they don’t recommend it unless clients express interest. “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college,” says Ian Harvey, a certified financial planner (CFP) in New York City. “Then it wasn’t worth the risk.” The speculative nature of cryptocurrency leads some planners to recommend it for clients’ “side” investments. “Some call it a Vegas account,” says Scott Hammel, a CFP in Dallas. “Let’s keep this away from our real long-term perspective, make sure it doesn’t become too large a portion of your portfolio.” In a very real sense, Bitcoin is like a single stock, and advisors wouldn’t recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if you’re passionate about it. “If it was one stock, you would never allocate any significant portion of your portfolio to it,” Hammel says.
In many cases, the content resembled that of the marketplaces found on the dark web, a group of hidden websites that are popular among hackers and accessed using specific anonymising software.“We have recently been witnessing a 100 per cent-plus rise in Telegram usage by cybercriminals,” said Tal Samra, cyber threat analyst at Cyberint.The rise in nefarious activity comes as users flocked to the encrypted chat app earlier this year after changes to the privacy policy of Facebook-owned rival WhatsApp prompted many to seek out alternatives.telegram from ye
