Painful stings like the velvet ants' venom actually evolved to defend them from insect predators, so it's surprising how well they target mammalian nociception ('pain-sensing') pathways.
There's a nice paper on this where they found velvet ant venom caused aversion in fruit flies, mice, and mantis.

Arizona velvet ants are colorful little insects that will DESTROY you. Their sting is described as 'hot oil from the deep fryer'. As wingless wasps, they will drop you to your knees. They will make you call to god. They are the reason countless children are afraid of cute insects.

Just finished processing my HaLRGB image of the Andromeda Galaxy (M31)
At ~2.5 million light years away, Andromeda is our nearest spiral neighbour. The pink regions mark hydrogen-rich star-forming nebulae, while the dusty lanes and bright core reveal stunning depth.

Noodling what it would take to visit Europe again. Some of that's directed, like looking at suggestions from other travelers and seeing what guided tours do. But other things I do are literally zooming in on maps and seeing what a place in an area I'm interested in is like.

Imagine it's 1850 and you've just been flattened by an elite cavalry officer who just yells "SOWWY" as he thunders away.
![Screenshot of a tweet:
British cavalry in the 1850s consisted entirely of twinks who used UwU-speak...
[Photo of a book page] "The dash of British cavalry officers was never greater than at the opening of the Crimean campaign in the spring of 1854. These aristocratic horsemen were, in the idiom of the day, "plungers," "tremendous swells." They affected elegant boredom, yawned a great deal, spoke a jargon of their own, pronouncing "r" as "w," saying "vewwy," "howwid," and "sowwy," and interlarded sentences with loud and meaningless exclamations of "Haw, haw." Their sweeping whiskers, languid voices, tiny waists, laced in by corsets, and their large cigars were irresistible, frantically admired, and as frantically envied. Magnificently mounted, horses were their passion; they rode like the devil himself, and their confidence in their ability to defeat any enemy single-handed was com-plete. Cavalry officers were saying in London drawing-rooms that to take infantry on the campaign was superfluous; the infantry would merely be a drag on them, and had better be left at

Salt Lake City and Detroit were two airports that I regularly had good experiences in back when i used to travel regularly
Actually, you know what? Let’s stop complaining for a second. QT this with a GOOD airport. Defend that title as much or as little as you like. But let’s hear about airports that don’t suck.

There's a story popularized by Grace Hopper, computer pioneer, about a 1947 failure in the Harvard Mark II computer that was traced to a moth trapped in an electrical relay.
Here's a photo of the operator log, with the attached bug.
