If so, that means the person was exposed to more testosterone in the womb. If reversed then they were exposed to more estrogen.
Funnily, I've learned about this in a Planet Dolan video, something I had started watching to get references for a CWC drawing I'm working on. TFW you actually learn something thanks to OPL...
 
Planar deformation features, or PDFs, are optically recognizable microscopic features in grains of silicate minerals (usually quartz or feldspar), consisting of very narrow planes of glassy material arranged in parallel sets that have distinct orientations with respect to the grain's crystal structure.

PDFs are only produced by extreme shock compressions on the scale of meteor impacts. They are not found in
volcanic environments. Their presence therefore is a primary criterion for recognizing that an impact event has occurred.

tl;dr They're tiny markings in rocks that show a meteor was there.
 
There are at least three, and up to possibly five, bats inside an old local playhouse that enjoy participating in the theatrics. They appeared during Dracula, and in a very dramatic death scene from another show, one was circuling the "dying" actress from above, its shadow flitting around her. The tech manager managed to convince a few audience members that he was controlling a robotic bat he built just for the show.

The show Im in, they divebombed the spotlight operators, the crew backstage (including me), and scared the women out of their dressing room. They possibly divebombed the audience too, I couldnt see. During a very dramatic and tension filled scene too. Which kinda fit, since the last act is all about awful secrets coming to light, but still.

At least they found a use for 'em, even if for a specific reason!
 
TIL There's a squirrel in Norse mythology named Ratatoskr that liked to spread drama by playing the messenger between the chaotic dragon, Nidhogg and the eagle on top of Yggdrasil, telling slanderous gossip. That squirrel's a real piece of shit. Fuck that guy.
 
"Although Hyenas lack perineal scent glands, they have a large pouch of naked skin located at the anal opening. Large anal glands above the anus open into this pouch. Several sebaceous glands are present between the openings of the anal glands and above them.[20] These glands produce a white, creamy secretion that the hyenas paste onto grass stalks. The odour of this secretion is very strong, smelling of boiling cheap soap or burning, and can be detected by humans several metres downwind.[31] The secretions are primarily used for territorial marking, though both the aardwolf[8] and the striped hyena[32] will spray them when attacked."

Scent-marking in the animal kingdom is nothing new to me, but hyenas have a version that smells like soap? What the fuck?

I learned that Richard Ramirez, aka the Night Stalker, hung out around my hometown in the mid 1980's. My parents were in high school at the time and have distinct memories of a creepy guy with dark curly hair that would hang out around their friend group despite being too old to be in high school. It wasn't until fairly recently that anyone realized whi he was. No wonder I attract so many weirdos, this shit is genetic.
 
If you try to put out a chip pan fire with water, the water, which is denser than oil, sinks to the bottom of the pot and boils instantly, vaporizing and rising out of the pan, simultaneously lifting the burning oil out of the pot and causing the oil that's not on fire to combust, forming a massive growing fireball that will engulf your entire kitchen.
