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.
На некоторые жалобы чиновники отвечали, что фото грызуна старое и не соответствует действительности. Тогда одна из художниц арт-центра «Пушкинская-10» распечатала посты Telegram-канала «Фонтанки» с датой и сняла крысу на их фоне.

We fixed in issue where the window switcher could leave a non-interactive area on screen when closed, plus an issue where the 6th and 13th keypresses could be skipped while Alt + Tabing. We fixed a couple of issues with multitasking, including ones with fullscreen windows not properly being moved, animations when reordering workspaces, and missing icons in the show all windows view. Plus we fixed blurry picture-in-picture resize icons on fractionally scaled displays.
