230-苔藓植物的基因家族空间大于维管植物
from 聊聊Sci
这篇研究通过对 123 个新测序的苔藓植物基因组进行全面的超级泛基因组分析，揭示了苔藓植物在经历五亿年进化后，其基因家族多样性显著高于维管植物。研究发现，苔藓植物的基因组进化主要由持续的新基因创新和微生物基因的水平转移驱动，这赋予了苔藓植物丰富的遗传工具包。这些独特的进化机制可能解释了苔藓植物在各种栖息地（包括极端环境）中的生态适应性和长期成功。该论文强调了新测序的苔藓植物基因组对于探索陆地生存替代进化策略的宝贵价值。References: Dong S, Wang S, Li L, 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.
