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 Fairphone 6 costs £499 (€599), making it cheaper than previous models and pitting it squarely against budget champs such as the Google Pixel 9a and the Nothing Phone 3a Pro, while being repairable at home with long-term software support and a five-year warranty. On paper it sounds like the ideal phone to see out the decade.
