1224-ROAST：无参考基因组超级转录组组装优化工具

这份研究报告介绍了一种名为 ROAST 的生物信息学工具，旨在优化非模式生物的超级转录组（supertranscriptome）组装质量。由于传统的组装软件常会产生片段化、冗余或嵌合体等错误，ROAST 采用了一种无需参考基因组的迭代算法，通过分析 Illumina 双端测序数据的报错特征来修复这些缺陷。该工具利用软切片（soft-clips）、异常表达覆盖度以及失配读取方向等信号，能够自动识别并修正局部组装错误。实验证明，ROAST 在模拟和真实数据集上均显著提升了组装的完整性与准确性。这种方法摆脱了对近缘物种比对的依赖，为缺乏高质量基因组数据的研究提供了高效的组装优化方案。该软件采用 C++ 编写，并已作为开源工具供学术界使用。References:Shabbir M, Mithani A.

Forfeiture Book Review: Ecocide and Sci-Fi JP et al. A whizz bang review of the complex themes in the new ecological Sci-Fi novel, FORFEITURE by JP Nebra 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.
