1482-铁催化脂质过氧化驱动蓝藻水华崩溃
from 聊聊Sci
这项研究揭示了铁催化的脂质过氧化是如何引发蓝藻暴发后的爆发性集体死亡。研究发现，在微囊藻群体中，单细胞内的亚铁离子过载会触发脂质过氧化链式反应，产生能使细胞膜破裂并形成纳米孔道的缩短链脂质过氧化物。这种被称为铁死亡的过程不仅能迅速导致个体细胞死亡，还会通过释放活性脂质信号向相邻细胞扩散死亡信息。这种非随机的空间扩散机制解释了藻华为何能在数日内大规模崩溃，并为治理有害藻华提供了潜在的调控策略。通过实验模拟与野外监测，该科研团队确证了铁死亡是协调藻类种群集体瓦解的核心生理机制。References:Zhu Y, Wang X, Tong Y, 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.
