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.

The most obvious trend is continued growth in AI search usage. As more people discover tools like ChatGPT, Claude, and Perplexity, and as these tools improve their interfaces and expand capabilities, the percentage of information-seeking behavior flowing through AI models will increase. This doesn't necessarily mean traditional search engines will disappear, but it does mean the traffic pie is being redivided, with AI search claiming an expanding slice.
