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.
最近几天，中国低成本大语言模型深度求索（DeepSeek）欧美AI圈引起了不小的震动。据悉，来自杭州的初创企业深度求索1月20日发布DeepSeek-R1，该模型在测试表现、训练成本和开源开放程度等多个基准测试中均超越“ChatGPT之父”美国OpenAI公司的最新模型o1，但成本仅为o1的三十分之一。
