科学家可能找到了阻止秃顶的方法
#科学

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。

The lead from Wall Street offers little clarity as the major averages opened lower on Friday and then bounced back and forth across the unchanged line, finally finishing mixed and little changed.The Dow added 33.18 points or 0.10 percent to finish at 34,798.00, while the NASDAQ eased 4.54 points or 0.03 percent to close at 15,047.70 and the S&P 500 rose 6.50 points or 0.15 percent to end at 4,455.48. For the week, the Dow rose 0.6 percent, the NASDAQ added 0.1 percent and the S&P gained 0.5 percent.The lackluster performance on Wall Street came on uncertainty about the outlook for the markets following recent volatility.

What Is Bitcoin?

Bitcoin is a decentralized digital currency that you can buy, sell and exchange directly, without an intermediary like a bank. Bitcoin’s creator, Satoshi Nakamoto, originally described the need for “an electronic payment system based on cryptographic proof instead of trust.” Each and every Bitcoin transaction that’s ever been made exists on a public ledger accessible to everyone, making transactions hard to reverse and difficult to fake. That’s by design: Core to their decentralized nature, Bitcoins aren’t backed by the government or any issuing institution, and there’s nothing to guarantee their value besides the proof baked in the heart of the system. “The reason why it’s worth money is simply because we, as people, decided it has value—same as gold,” says Anton Mozgovoy, co-founder & CEO of digital financial service company Holyheld.
