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.
与AI服务器“抢食”内存产能的同时，手机自身对内存的需求也在急剧膨胀。CounterPoint Research发布报告称，2025年12月全球智能手机平均内存（DRAM）为8.4GB，创历史新高。在高端手机市场（售价超600美元），平均内存容量更是达到了约11GB。为了满足高强度多任务处理和端侧大语言模型（LLM）的本地运行需求，12GB内存正在迅速成为高端智能手机的基础标准配置。
