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.
这些词放在一份硅谷顶级风投的年度展望里，多少有些违和。过去二十年，风险投资的逻辑是逃离物理世界——越轻越好，越数字化越好，最好是纯软件，边际成本为零，可以无限复制。工厂、矿山、流水线，太重、太慢、太难标准化，不是VC该碰的生意。
