385-IRIS：高效精准的空间转录组组织分割法
from 聊聊Sci
这项研究介绍了一种名为 IRIS 的计算方法，旨在更精确、高效地识别空间转录组学 (SRT) 数据中的组织结构区域。与传统方法不同，IRIS 创新性地利用单细胞 RNA 测序 (scRNA-seq) 数据作为参考，直接建模组织内各区域特有的细胞类型组成特征。该方法不仅能整合多个组织切片的信息，还能跨越不同物种和技术平台，处理具有数百万个空间位置的大型数据集。通过对大脑结构、肿瘤微环境及病理变化的研究，证明了 IRIS 在识别生物学领域方面的准确率提升了高达 10 倍以上。同时，其运行速度较现有方法提升了数十倍乃至数百倍，为理解复杂组织的空间功能组织提供了强大的工具。References: Ma, Y., Zhou, X.

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.
