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 alarm comes from changes in the way taxpayers’ money is invested by UK Research and Innovation (UKRI), which recently published its plan on how to disburse £38.6bn of public research and development funding over the next four years. Change is always unsettling, and as the UKRI’s chief executive, Ian Chapman, says, there will always be those who lose out when change happens. Difficult choices must be made.
