科学家可能找到了阻止秃顶的方法

2025-03-30 17:31 by 人猿泰山之密林追踪

治疗秃顶甚至预防秃顶距离我们又近了一步。研究人员发现,负责头发生长的毛囊干细胞 (HFSC) 需要一种起到“保镖”作用的蛋白质 MCL-1。如果 MCL-1 因为压力、衰老、抗癌药物或遗传等降低水平,HSFC 会逐渐筋疲力尽最终走向死亡,也就不会长出新头发了。研究人员通过关闭生成 MCL-1 蛋白质的基因并剔除实验鼠的现有毛发演示了其作用。他们发现 HFSC 存活了一段时间,但最终因为触发压力信号 (P53)而走向死亡。研究报告发表在《Nature Communications》期刊上。最新发现为治疗和预防脱发开辟了新的研究方向。

Spiking bond yields driving sharp losses in tech stocks

A spike in interest rates since the start of the year has accelerated a rotation out of high-growth technology stocks and into value stocks poised to benefit from a reopening of the economy. The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year. A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.

Can I mute a Telegram group?

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.
