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.
Anxiety is growing over a potential war between Iran and the US in the Middle East, with embassies evacuating staff and airlines cancelling flights as tensions mount.

India is Supabase’s fourth-largest source of traffic, accounting for about 9% of global visits, according to data from Similarweb, highlighting the potential fallout for the country’s developer ecosystem. The platform’s global traffic jumped more than 111% year over year to about 4.2 million visits in January. In India, visits rose roughly 179% to about 365,000, compared with a 168.5% increase in the U.S. to about 627,000.。同城约会对此有专业解读
