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.

I feel compelled to point out that Ramy Bensebaini played left-sided centre-back of a back three against Atalanta rather than left-back (yesterday’s Football Daily). I noticed this because of the body language of his teammate Daniel Svensson each time Bensebaini recklessly served a goal up on Wednesday. Svensson was the recovering left wing-back at the Algerian’s side, head bowed and shoulders increasingly drooping” – Matthew Parham.
