3. Greenland is a beautiful nightmare (matduggan.com)

Greenland is a complicated topic here in Denmark. The former colony that is still treated a bit like a colony is something that inspires a lot of emotions. Greenland has been subjected to a lot of unethical experiments by Denmark, from taking their kids to wild experiments in criminal justice.

8. Samsung now owns Denon, Bowers and Wilkins, Marantz, Polk, and more audio brands (www.theverge.com)

三星子公司哈曼(Harman)已完成对原属马西莫(Masimo)的音响业务“Sound United”的收购,交易金额达3.5亿美元。此次收购将宝华韦健(Bowers & Wilkins)、天龙(Denon)、马兰士(Marantz)、Definitive Technology、Polk Audio、HEOS、Classé 和波士顿声学(Boston Acoustics) 等多个知名音响品牌纳入三星音频品牌组合,与此前已收购的JBL、哈曼卡顿(Harman Kardon) 等品牌归于同一集团。

哈曼生活方式部门负责人戴夫·罗杰斯表示,Sound United 品牌阵容与哈曼在声音、创新和品质方面的价值观一致,此次交易将为双方创造显著增长机会,并巩固哈曼在音频领域的领导地位。

为保障各品牌保持其独立性和客户基础,Sound United 将作为哈曼生活方式部门旗下的独立业务运营。

21. Thoughts on Mechanical Keyboards and the ZSA Moonlander (www.masteringemacs.org)

Mechanical keyboards, the nerd equivalent of obsessing over ferrule weights in golf clubs, are wildly popular, and for a good reason. I've owned and used a ZSA Moonlander for some years now, and here are my thoughts on it and why I think you should literally buy any mechanical keyboard you can get your hands on with programmable firmware. Your fingers will thank you.

研究概要

一项由纽约大学朗格尼健康中心及其佩尔穆特癌症中心主导的最新研究表明,人类口腔中栖息的某些细菌和真菌的组合,与胰腺癌风险显著升高密切相关。这项研究于2025年9月18日在线发表在《JAMA Oncology》杂志上。

核心发现

  • 风险关联:研究人员鉴定出27种口腔微生物(包括细菌和真菌),它们共同存在时,与胰腺癌风险增加3.5倍相关。
  • 研究规模:该分析是迄今为止规模最大、最详细的同类研究。它评估了来自两项大型美国全国性研究(美国癌症协会癌症预防研究II及前列腺癌、肺癌、结直肠癌和卵巢癌筛查试验)中约122,000名健康男女的唾液样本。
  • 真菌的首次纳入:该研究是首次显示口腔真菌——特别是自然存在于人体皮肤和体内的念珠菌属的某种酵母菌——可能在胰腺癌中发挥作用。研究人员还在患者的胰腺肿瘤中也鉴定出了这些口腔念珠菌。
  • 具体微生物:研究共识别出24种单独或升高或降低胰腺癌风险的细菌和真菌物种。另外三种与胰腺癌相关的细菌已被知会导致牙周病。

研究方法与背景

研究人员分析了参与者使用漱口水后提供的唾液样本中的细菌和真菌DNA。他们随后平均跟踪参与者约九年以记录肿瘤的发生。在研究中,他们对比了445名后来确诊胰腺癌的患者与445名未患癌的随机选取对象的微生物DNA,并考虑了年龄、种族和吸烟频率等已知风险因素。

意义与展望

  1. 筛查工具:研究首次开发了一种工具,通过分析个人口腔微生物组成来评估其胰腺癌风险。这有助于肿瘤科医生识别出最需要接受胰腺癌筛查的高危人群。
  2. 口腔健康的重要性:研究共同资深作者强调,该发现进一步表明,保持口腔卫生(如刷牙和使用牙线)不仅有助于预防牙周病,也可能对预防胰腺癌具有保护作用。
  3. 研究局限与未来方向:研究人员指出,该研究旨在识别疾病风险与口腔中某些微生物之间的关联,而非确立直接的因果关系,这需要进一步的研究证实。研究团队计划接下来探索口腔病毒是否也可能导致癌症,以及口腔微生物组如何影响患者的生存机会。

资助与作者

该研究由美国国立卫生研究院的多项资助支持。论文作者来自纽约大学朗格尼健康中心、阿尔伯特爱因斯坦医学院、美国国家癌症研究所和美国癌症协会等多个机构。

24. Why We Think (lilianweng.github.io)

Special thanks to John Schulman for a lot of super valuable feedback and direct edits on this post. Test time compute (Graves et al. 2016, Ling, et al. 2017, Cobbe et al. 2021) and Chain-of-thought (CoT) (Wei et al. 2022, Nye et al. 2021), have led to significant improvements in model performance, while raising many research questions. This post aims to review recent developments in how to effectively use test-time compute (i.e. “thinking time”) and why it helps.

25. AI model trapped in a Raspberry Pi (blog.adafruit.com)

Latent Reflection (2025) 是一个由科技艺术家 Root Kid 创建的电子艺术装置。该装置由一块 Raspberry Pi 4B 单板计算机驱动,运行量化的 Llama 3.2-3B 大型语言模型。硬件部分包括一个由96个16段LED模块组成的6x16矩阵显示器,安装在铝制面板上。

装置的核心功能是让AI模型进行内省反思:通过初始提示,LLM被引导思考其自身的有限存在,生成的思考内容逐词显示在LED显示屏上。这个过程持续进行,直到系统内存耗尽,触发自动重启,形成一个循环。这类似于电影《记忆碎片》的概念,LLM被困在自己的“心智”中,经历存在主义的螺旋直至崩溃并重新开始。

该作品探索了人工自我意识的概念,通过公开展示AI对其受限和短暂状态的无掩饰反思,涉及暴露意识、技术限制和循环无常等主题。在测试阶段,Root Kid曾创建动态眼睛图形显示,呈现出赛博朋克风格的效果。
