I’m taking a few days off to catch-up on a few neglected projects. So today’s newsletter is a re-run of an old favorite. If you need some cheering up, this should do it.

See you next time!

So how are you holding up in this crazy time? Sleeping OK? Would a really sweet fact help out? If so, I’ve got you covered: Giraffes hum to each other during the night. Isn’t that the sweetest thing you’ve heard all year?

This isn’t just some random vocalization. The researchers who discovered this hum described it as “a low-frequency vocalization with a rich harmonic structure.” Of course no one has any idea what giraffes are communicating with these sounds — or even if they are communicating. But it’s likely they’re saying something, in part because of the complex variations in frequency and harmonic structure. In an interview with The New Scientist, one of the researchers said the hums might be produced while the animals are in a dream-like state.

So maybe giraffes are singing about their dreams? Or perhaps they’re just trying to soothe each other in the dark. In any case, I sleep better just thinking about giraffes humming to each other at night.

’til next time — sweet dreams!
