By WWII, scientists had already begun looking at alternative gelling substances for routine use in bacteriology, but concluded that agar was still better as it is both firmer and easier to handle. Today, some specialized microbiology applications use the colloid carrageenan (extracted from red seaweed Chondrus crispus, or “Irish Moss”), a more transparent and less auto-fluorescent alternative to agar (agar emits its own background fluorescence when excited by light). However, for routine bacteriological use, carrageenan is more difficult to dissolve, requires higher concentrations, can degrade at high temperatures, and forms weaker gels, which may result in puncturing its surface during the plating of cells.

在过去，多终端窗口多agent工作的场景下，你可能需要在 Claude Code、Cursor 或不同终端窗口间来回切换，然后复制粘贴另一个窗口的输出作为上下文。现在，你只需待在你最习惯的 Agent（比如 Claude Code 或 OpenClaw、Trae）里，像指挥官一样下令："用 mco 调度 Codex 和 Gemini (或者其他市面上各种的agent cli) 一起分析这个项目的架构。"，或者通过主agent给他们分配各自的任务并行去调度执行。，推荐阅读同城约会获取更多信息
