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。

草 熬了半个晚上准备看 Isar Aerospace 的 Spectrum 第一次发射，结果熬到一半昏迷了。
Spectrum 是德国的 Isar Aerospace 开发的小型运载火箭，第一级由九枚 Aquila 丙烷/液氧 引擎提供动力，第二级有一枚真空优化的 Aquila 引擎。
今天的发射在挪威的 Andøya Rocket Range 进行，使得 Isar Aerospace 成为了第一个在欧洲本土发射火箭的私人公司。

With this test flight, we were able to successfully gather valuable data and experience for future missions. Thanks to strict safety procedures from both Isar Aerospace and Andøya Spaceport, all personnel remained safe at all times.

The demoscene as a UNESCO heritage in Sweden
The demoscene has become a national UNESCO-heritage in Sweden, thanks to an application that Ziphoid and me did last year. This has already happened in several European countries, as part of the international Art of Coding initiative to make the demoscene…

Fram2 任务将在大约1小时40分钟后发射进入90度极地轨道，将成为第一个从地球低轨道飞跃地球极区的载人任务。本次任务将会进行三到五天，执飞的龙飞船 C207 Resilience 将配备和 Inspiration 4 任务中同样的半球形窗口。
