1623-中国蜱虫及其微生物组基因组图谱
from 聊聊Sci
这项研究通过对中国境内48种蜱虫的1,479个样本进行大规模宏基因组测序，构建了一个涵盖7,783个细菌基因组的庞大数据库。研究人员发现了大量未曾记录的细菌物种，并揭示了地理环境、宿主种类及蜱虫自身遗传变异如何共同塑造其体内微生物群落的构成。分析显示，特定的内共生菌具有高度的属特异性，且蜱虫的特定基因多态性（SNPs）与其携带病原体的能力和代谢过程密切相关。这一成果不仅极大地扩展了人类对蜱传病原体多样性的认知，也为制定有效的蜱虫防治和传染病预警策略提供了关键的遗传学基础。References:Du L F, Shi W, Cui X M, 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.
