Agar was first introduced into the laboratory in 1881. Since then, microbiologists have depended on agar to create strong jellies. When microorganisms are streaked or plated onto this jellied surface and incubated, individual cells multiply into distinct colonies that scientists can easily observe, select, and propagate for further experiments. Many of the most important findings in biological research of the last 150 years or so — including the discovery of the CRISPR/Cas9 gene-editing tool — have been enabled by agar.4 Agarose, a derivative of agar, is also essential in molecular biology techniques like gel electrophoresis, where its porous gel matrix separates DNA fragments by size, enabling researchers to analyze and isolate specific genetic sequences.

對於中國解放軍而言,現在的局面也是史無前例的——在習近平上台前,根據公開資料統計,中共歷史上被處理的上將僅有一位黃永勝,他在1971年因林彪叛逃事件牽連而被處理。鄧小平、江澤民、胡錦濤時代都無上將被處理。習近平上台後,已有25名上將被開除黨籍、軍籍,其中除了徐才厚、郭伯雄等八人在習上台之前就已是上將,其餘都是他任內提拔,又在他任內被查。
