381-声学报告基因：实现深层组织的多重超声成像
from 聊聊Sci
这项研究开发了新型声学报告基因，首次实现了多重超声成像，能够同时观测活体深层组织中的多种细胞状态。科研人员通过蛋白质工程和定向进化技术，设计出具有不同声压响应特征的蛋白质纳米结构，并将其命名为 bARG560 和 bARG710。这些基因能够像荧光蛋白区分颜色一样，让研究者通过不同的超声频率或压力辨别不同的细胞群。实验成功在小鼠体内区分了益生菌种类，并实时监测了肿瘤定植细菌的分布情况。这一突破克服了光学成像穿透力差的局限，为深层生物组织的复杂功能研究提供了高分辨率的成像工具。该技术在细胞疗法追踪和活体分子诊断领域具有广阔的应用前景。References: Nyström N N, Jin Z, Bennett M E, 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.
