Scientist bakes sourdough bread with yeast derived from 4500 year old Egyptian pottery

is a sourdough boule

And in case anyone was wondering

TiL (click to go to the thread, which probably has more interesting tidbits I missed).

Bonus:

In addition to the print terminology stuff: the visual shorthand icons and ad graphics for something about writing are still often pen-nibs, fountain pens and typewriters…

…while graphics of a monitor, keyboard and mouse remain visual shorthand for computing…

…even though most writers now use monitor /  keyboard / mouse or even laptop / touchpad.

In addition, headers for “this blog / website is about writing” are often in one of the many imitation typewriter fonts complete with smudges, or just Courier.

The start and end call icons on most / all smartphones is still the handset of a classic desk telephone, and sometimes the open-app icon is a complete phone.

The term “hang up” for “end the call” refers to something even older - one of these…

And of course the Save icon is indeed a 3½ inch floppy disc.

Why it wasn’t a 5¼ floppy is a mystery. The icon version is just as distinctive.

Also, why various OP updates never changed “Save” to the graphic of a CD / DVD or flash drive is another mystery, and nowadays a Save icon should probably be a cartoon cloud.
