Let’s now imagine that the station is depressurized and, for the first time in decades, empty, operated entirely via computers and remote control. First, NASA and its partners must accept the need to deorbit—there’s no going back to save the ISS. This could be complicated: 23 countries in the European Space Agency, as well as Japan and Canada, are involved in the ISS partnership. And then there’s Russia. The Russians have committed to supporting the ISS only until 2028. But they did agree to help NASA in a contingency deorbit situation.
Two months ago, Aston Villa were just three points off top spot in the Premier League. They were on a run of 12 wins in 14 games that included victories against Manchester City and Arsenal. Their run of eight consecutive wins in the league was their best since they won 10 in a row in 1910. You wouldn’t have blamed Villa fans for daring to dream about lifting their first league title since 1981.

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.
