位于伊拉克南部米桑省的哈法亚油田，现代化厂区整洁美观，400多口油水井、5个高压注水泵站、3个油气中心处理厂和1个天然气处理厂昼夜不停生产作业。人们很难想象，15年前这里还是一片荒无人烟的偏远油区。

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.
