写作是艺术也是门手艺,而手艺活要分两步:先塑形,后抛光。第一稿是塑形,把那一团模糊的想法,所谓灵感,捏出个大概模样。这时候你要像个陶匠,手上沾满泥巴,没关系,关键是让坯子成型,有模有样。第二稿才是抛光、打磨,这时候你是一个编辑,是雕刻家,是一个让人“讨厌”的挑剔的人,是一个指手画脚的人,但也是那个让作品发光的人。这个过程很煎熬,但成果喜人。我听一位刊物编辑说,作家索南才让的《荒原上》,前前后后修改了十稿,最终获得了鲁迅文学奖。当然不是说所有稿件修改十遍后就能拿奖,但若没有这一历程,作品恐怕不会有现在这样的成色。
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.
