1537-GOOSE：蛋白质本质无序区的理性设计框架
from 聊聊Sci
本文介绍了 GOOSE，这是一个用于理性设计内在无序蛋白质区域（IDRs）的新型计算框架。由于 IDRs 缺乏稳定的三维结构且序列与功能关系复杂，传统设计方法难以对其进行有效操控。GOOSE 能够根据氨基酸组成、电荷模式和构象特征快速生成数千个序列，帮助研究人员在细胞内系统地探究其生物学功能。通过该工具，作者揭示了序列属性如何影响 IDRs 的空间构象、亚细胞定位以及对细胞压力（如渗透压变化）的响应。此外，该研究成功设计出具有特定自组装能力的蛋白质，以及能显著提高酵母抗脱水能力的新型序列。总之，GOOSE 为探索无序蛋白质的序列-功能规律提供了一个高效、通用的平台。References:Hunter K, Brandt T, Guadalupe 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.
