523-猕猴与人类胎盘类器官的演化差异比较研究
from 聊聊Sci
这项研究成功开发了恒河猴胎盘类器官模型，为模拟灵长类动物妊娠过程提供了重要的体外平台。通过应用单细胞和单细胞核转录组测序技术，科学家详细绘制了恒河猴胎盘细胞的分子图谱，并将其与人类数据进行了跨物种比较分析。研究结果揭示，虽然恒河猴与人类在合体滋养层细胞的遗传程序上具有高度相似性，但在滋养层细胞侵袭及相关基因表达方面存在显著的演化差异。该模型不仅能分泌关键的妊娠激素，还能够模拟滋养层细胞的多种分化路径。这项成果为深入理解灵长类胎盘发育提供了关键证据，并有助于探究母婴界面的演化适应机制。该研究建立的类器官系统也为未来研究妊娠相关疾病提供了比传统细胞系更精准的替代方案。References: Comparative analysis of rhesus macaque and human placental organoids highlights evolutionary differences in placentationCaldwell, Allyson et al.Developmental Cell, Volume 0, Issue 0前往小宇宙评论区与主播互动

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.
