1155-Renoir：空间配体-靶标活性图谱绘制框架
from 聊聊Sci
这篇论文介绍了 Renoir，这是一种用于分析空间转录组数据的创新型计算框架。Renoir 的核心功能在于能够精确绘制组织微环境中配体与靶基因之间的空间活动图谱，填补了以往研究仅关注配体-受体结合而忽略下游基因表达影响的空白。通过整合单细胞测序与空间定位信息，该工具可以识别具有特定细胞通讯模式的空间生态位，并对信号通路的活性进行空间标定。研究团队通过模拟数据集和多种生物样本（包括脑组织、发育中的胎肝及乳腺癌肿瘤）验证了 Renoir 的优越性，证明其能有效揭示复杂的细胞间对话。此外，该工具在肝癌研究中成功识别出了癌胎生态位与双潜能干细胞之间的相互作用，为理解组织发育和疾病机制提供了重要的生物学见解。References:Rao N, Kumar T, Kazemi D, 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.
