738-幕上室管膜瘤的异质性与发育景观
from 聊聊Sci
这篇研究论文利用单细胞测序与空间转录组学技术，深度剖析了幕上室管膜瘤（ST-EPN）的细胞异质性。研究者发现，这种侵袭性儿童脑肿瘤具有模拟人类大脑早期发育的特定细胞状态，并识别出两类互斥的祖细胞样状态。通过空间定位分析，论文揭示了肿瘤内部存在高度有序与无序两种不同的组织架构，且这些模式与间充质/缺氧信号密切相关。此外，实验证明了肿瘤微环境在诱导恶性细胞向神经元样表型转化中起着关键作用。这些多维度的发现为理解肿瘤的发生机制提供了新框架，并为未来的精准医疗干预奠定了理论基础。References: Jeong D, Danielli S G, Maaß K K, 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.
