Happy Friday, everyone.

Also, happy 30th birthday to the Hubble Telescope! For something with such an unsteady beginning, it’s had an incredible life.

From Satori: “A similar epidemic in Northern China in 1910/1911 originating from the marmot fur trade… a very interesting compare/contrast on why and how it didn't get out to the rest of the world."

And finally, meet Pepper the hedgehog, conquering the increasingly difficult living room obstacle course! (The narration is wonderful.)

Have a safe and spiffy weekend, everyone. See you next week.
