358-DNA甲基化应用于中枢神经系统肿瘤诊断
from 聊聊Sci
这份研究介绍了海德堡中枢神经系统（CNS）肿瘤DNA甲基化分类器从v11到v12.8版本的重大升级。通过全球协作与庞大的在线数据库，该分类器识别的肿瘤亚类从91个翻倍扩展至184个，显著提升了对罕见及异质性肿瘤的诊断能力。新版本引入了四级分层结构（超家族、家族、类、亚类），使分类结果能够更好地与世卫组织（WHO）标准对齐，并提供经校准的概率评分以辅助临床决策。性能评估显示，v12.8在亚类水平上的准确率高达95%，成功解决了此前许多无法归类的病例。此外，该工具在预后评估方面表现卓越，能够通过分子特征区分传统组织学容易混淆的高低级别胶质瘤。总之，这一进步不仅增强了神经肿瘤学的精准诊断，也通过开源与国际合作促进了全球医疗公平。References: Sill M, Schrimpf D, Patel A, 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.
