1046-肿瘤发生初期的活体成像与观察技术研究
from 聊聊Sci
这篇综述探讨了利用活体显微镜、组织透明化和空间转录组学等前沿成像技术观察癌症早期发生的机制。这些工具将肿瘤起始从理论推测转变为可在生物体内直接观测的动态过程，揭示了突变克隆如何通过竞争或合作在组织中生存与扩张。研究发现，突变细胞的命运受细胞层级、微环境信号以及宿主代谢等系统性因素的共同调控。通过精准追踪单个突变克隆的演化规律，科学家能够识别出具有恶变潜力的“突变场”。这些技术突破不仅深化了对癌变机理的理解，也为肿瘤的早期拦截和预防提供了关键视角。这种多维度的观测手段正在重塑癌症生物学的研究范式。References:Messal H A, Mourao L, Dörner L, et al.

Deep Dream State
Neural Nets And Pretty Patterns
Deep Dream State is a full-cast dystopian sci-fi and desire horror audio drama by Neural Nets and Pretty Patterns. As the originating work of desire horror, it locates the uncanny inside wanting itself. While conventional horror positions you against a threat, desire horror implicates you in it. The horror emerges from recognition: the realization of why characters stay, and why surrender feels like relief. Since 2017, the show has used research in dream science, surveillance studies, behavioral economics, and advertising technology to examine systems of control through immersive sound design and full-cast performance.
