It looks like ISS will transit the sun in Tuscaloosa, AL (33.206667, -87.534722) on Wednesday Dec. 13. The three tools that I've looked at show slightly different ideal locations and times for the transit. Who should I believe:

For a potassium source that's not too basic, I'm adding potassium citrate to La Croix sparkling water, which I'm assuming is acidic (carbonic acid?). What is happening when it starts fizzing? [more inside]
A good and terribly brilliant friend is currently a college freshman with a life-long enthusiasm for the insect world, and an eye toward a career in entomology. Her passion: spiders.

What kinds of non-abilities are some small percentage of humankind born with that don't affect their everyday life and, in fact, may not be discovered as a non-ability until later in life? [more inside]
Flat Earthers fascinate me. Mostly because it's such a pure conspiracy theory; it's good to see someone standing up to Big Sphere. What kind of experiment could I carry out for an open-minded Flat Earther that would demonstrate the Earth isn't a disk? There's the old "ship disappearing beyond the horizon" thing, but that's something you rarely (if ever) see with your naked eye. Presume that I'm willing to throw a little but of money into this.

I'm sure that I've read about species (animal or plant) which went extinct because they had some specific sexual habit or preference or requirement which turned out to not be very robust in the face of change. However, I'm having trouble thinking of any examples now. Is this a thing that actually happens? Can you think of examples?
Thought experiment: two conflicting concepts regarding weight loss where the math doesn't add up and is completely contrary to real life conditions. [more inside]
I visit this site a few times a week and have never seen this many recorded before. No where close. Is this unusual? If so what's up?
