围炉之“炉”,从前是炭火炉,如今是电磁炉。不变的是在氤氲的热气里,一家人坐着塑料凳,在木桌前簇拥着,必须起身才够得到对角线的菜。夹肉的筷子频频打架,火锅沸腾到锅盖跳舞了才手忙脚乱地关掉,身后的电视机明明开了很大声音,却总是什么也听不清。

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.
