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.
那几年，阿爸的气色慢慢好起来。他的亲生奶奶有几年也会过来看一看。人来了，坐一会儿，问几句身体情况，就走了。有一次，我听阿爸的亲姐姐说，这个弟弟是几个孩子里最乖巧的，小时候不该卖出去，她好不甘心。

Under the original Artemis architecture, NASA planned on multiple versions of the SLS rocket, ranging from the "Block 1" vehicle currently in use to a more powerful EUS-equipped Block 1B and eventually an even bigger Block 2 model using advanced solid rocket boosters. The latter two versions required use of a taller mobile launch gantry, already well under construction at the Kennedy Space Center.
