Cells are the fundamental units of biological systems and exhibit unique development trajectories and molecular features. Our exploration of how the genomes orchestrate the formation and maintenance of each cell, and control the cellular phenotypes of various organismsis, is both captivating and intricate. Since the inception of the first single-cell RNA technology, technologies related to single-cell sequencing have experienced rapid advancements in recent years. These technologies have expanded horizontally to include single-cell genome, epigenome,proteome, and metabolome, while vertically, they have progressed to integrate multiple omics data and incorporate additional information such as spatial sc RNA-seq and CRISPR screening. Single-cell omics represent a groundbreaking advancement in the biomedical field,offering profound insights into the understanding of complex diseases, including cancers. Here, we comprehensively summarize recent advances in single-cell omics technologies, with a specific focus on the methodology section. This overview aims to guide researchers in selecting appropriate methods for single-cell sequencing and related data analysis.

Breaking new ground in photocatalysis: lutetium texaphyrin as a trigger for pyroptosis through biomolecular photoredox reactions

Malignant neoplasms consistently pose a significant threat to global public health [1,2]. In recent years, immunotherapy has demonstrated remarkable clinical success; however, its efficacy is limited by the scarcity of immune cell infiltration within tumor microenvironments. Cell pyroptosis, a gasdermin-mediated process characterized by cellular swelling,rupture, and the release of intracellular contents such as IL-1β, IL-18, ATP, HMGB1, plays a crucial role in this context[3,4].

文明是中国共产党百余年推进马克思主义中国化时代化的核心线索,文明叙事是中国共产党历史叙事的重要维度,也是习近平文化思想的重要方法论。习近平文化思想的深厚文明意蕴体现在四个方面:一是从历史纵深出发把握“走自己的路”的文明基因,即从中华5000多年文明的历史传承中把握中国道路的来龙去脉及其内在逻辑必然;二是以“第二个结合”为根本方法,重塑发展中华文明的使命担当,不断推动建设中华民族现代文明实现传统文明的现代新生;三是坚守文明超越理念,将新文明的建构与中国式现代化的现实实践相互关联,以中国式现代化创造人类文明新形态,打破西方以资本逻辑为核心的形而上学抽象文明观的历史困境;四是坚持文明交流互鉴,推动落实全球文明倡议,构建人类文明交往新范式。
