The Dutch love four-day working weeks, but are they sustainable?
“In the manifold of breakfast, are there empty subspaces? Might there be breakfasts that no one has ever had? With a theoretical model of breakfast, can we derive the existence of ‘dark breakfasts,’ breakfasts that we know must exist, but have never observed?”

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.
