CRISPR-Cas 基因编辑在实验室中完全消除 HIV 病毒
2024-03-20 18:41 by 猿朋豹友
荷兰阿姆斯特丹大学的研究人员报告,他们利用 CRISPR 基因编辑技术,成功的从受感染细胞中消除了 HIV 病毒。HIV 治疗的重大挑战之一是该病毒具有将自身基因组整合到宿主 DNA 中的能力,尽管目前有多种有效的抗病毒药物用于治疗 HIV 感染,但只能抑制 HIV 在人体内的复制,无法将其清除,故患者需要接受终身抗病毒治疗,因为一旦抗病毒治疗停止,HIV 可能会卷土重来。HIV 可以感染体内不同类型的细胞和组织,每种细胞和组织都有其独特的环境和特征。在这项研究中,荷兰研究人员使用“分子剪刀”与两种 gRNA(向导 RNA) 来对抗所有已知的 HIV 毒株中保持相同的病毒基因组部分,并成功治愈了 HIV 感染者的 T 细胞。荷兰研究人员证明,当在培养皿中的免疫细胞上进行测试时,他们的 CRISPR 系统可以灭活所有 HIV 病毒,将其从免疫细胞中清除。研究人员强调他们的工作仍然只是“概念证明”,不会很快成为 HIV 的治疗方法。

Show HN: Memories – FOSS Google Photos alternative built for high performance (🔥 Score: 160+ in 3 hours)
Link: https://readhacker.news/s/64xYH
Comments: https://readhacker.news/c/64xYH
Memories is a FOSS Google Photos alternative that you can self-host (it runs as a Nextcloud plugin).
Website: https://memories.gallery/
GitHub: https://github.com/pulsejet/memories
Demo Server: https://demo.memories.gallery/apps/memories/
(demo runs in San Francisco on a free-tier cloud vm)
Memories has been built ground-up for high performance and is extremely fast when configured correctly. In our testing environment, it can load a timeline view with 100k photos in under 500ms, including query and rendering time!
Some features to highlight:
* A timeline similar to Google Photos where you can skip to any time in history instantly.
* AI-based tagging that runs locally on your server, identifying and tagging people and objects.
* Albums and external sharing.
* Metadata editing support
* A world map of your photos, supported both on mobile and the web
* Did I mention it's extremely fast?
Would love to hear feedback from the HN community! :)

DuckDB as the New jq
Recently, I’ve been interested in the DuckDB project (like a SQLite geared towards data applications). And one of the amazing features is that it has many data importers included without requiring extra dependencies. This means it can natively read and parse…

虽然不知道为什么,但是 YouTube 推荐算法最近把这个空客祝波音 100 年诞辰的视频推到各种奇怪的地方。
感觉更缺德了。

十年前,如果有人告诉我说,《三体》是他看过的最棒的科幻小说。我会回答他说三部的水平参差不齐,说文笔尤其是对女性的描写还有提升空间,说这套书后面的世界观过于暗黑和狭窄。这些都是我的真实想法,但是在对方那里听起来就像是一种反驳,甚至是一种否定,认为我在驳斥他的个人判断。
现在我不会那么说了,我会回答他说:既然你那么喜欢科幻小说,有一套《基地》也很不错,如果觉得篇幅太长,可以考虑一下《海伯利安》。这里没有那种中国社会里的传统法术:对别人的观点和想法不置一词,然后想办法让对方知道“什么才是真正的好东西”,于是在保全了对方面子的同时也折服了对方。我没有这种想法,我现在的想法很简单---
对方和我说那一番话,我理解为他在向我介绍或者推荐他认为最好的东西。这应该被理解为一种善意,所以我个人是否认同并不重要。那么作为一种对善意的回馈,我也把我认为不错的东西介绍给他,这样大家有来有往。至于说他是否接受,是否赞同,也不在我的考虑之中。
