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.
2023年5月，习近平总书记在河北考察并主持召开深入推进京津冀协同发展座谈会时强调：“推动京津冀协同发展不断迈上新台阶，努力使京津冀成为中国式现代化建设的先行区、示范区。”2026年1月，中共中央、国务院批复《现代化首都都市圈空间协同规划（2023—2035年）》，明确“围绕完善首都功能区域布局，牢牢牵住疏解北京非首都功能这个‘牛鼻子’”“建成以首都为核心的世界一流都市圈、先行示范中国式现代化的首善之区，支撑京津冀世界一流城市群建设”。
