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.
Friedmann began appealing his conviction in 2023. Last summer, the appeal was denied. In December, the Tennessee Supreme Court declined to review the case. Friedmann is now in the Bledsoe County Correctional Complex, in Pikeville, where he is still writing. He has been contributing to the online magazine of the Prison Journalism Project, covering minor injustices, such as the comparatively high cost that his Muslim prisonmates have to pay for Qurans. He has not lost his sense of humor. Recently, he wrote an essay called “The Art of the Prison Fart.” In 2022, his play “Twenty Years in Solitary” earned him another first-place award from PEN America.
