300-基因驱动编程肿瘤进化以克服耐药性
from 聊聊Sci
这份研究文章介绍了一种名为选择基因驱动（selection gene drives）的新型癌症疗法，旨在主动对抗肿瘤对靶向抗癌药物产生的耐药性。该系统通过在癌细胞中引入一个双开关遗传回路，将可诱导的适应性优势与共享的适应性成本相结合，从而重新规划肿瘤的进化轨迹。研究人员利用随机模型来确定最佳设计标准和治疗方案，并在体外实验中构建了原型，证明了该系统能够消除多种形式的遗传耐药性。最终，通过在小鼠实体瘤模型中进行实验验证了这种模型指导的开关激活方法能够有效靶向并清除预先存在的耐药细胞，提供了一种以进化为导向的抗癌治疗框架。References: Leighow S M, Reynolds J A, Sokirniy I, 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.
