857-RNU4-2饱和基因组编辑揭示显性与隐性遗传病相关性
from 聊聊Sci
这份研究通过饱和基因组编辑（SGE）技术，系统地评估了非编码基因 RNU4-2 中数以百计变异的功能影响。研究者发现，该基因中特定的核心区域变异会导致常染色体显性遗传的 ReNU 综合征，且变异的功能评分与患者临床表型的严重程度高度相关。此外，研究还首次确定了该基因其他功能区的变异会引发一种全新的、临床特征独特的隐性遗传神经发育疾病。通过构建高分辨率的变异功能图谱，该研究显著提升了临床诊断的准确性。这些成果为理解剪接体相关疾病的分子机制提供了关键见解，并为相关罕见病的治疗开发奠定了基础。References: De Jonghe J, Kim H C, Adedeji 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.
