Is it possible to receive an electric shock when you *stop* touching something?

I seem to remember as a young child being told that it is safe to touch a Van de Graff generator (for the hair demonstration), but that if you let go before it is safe you will get a nasty shock. I know a bit more about electricity now, and I’m a little skeptical now. Is it possible to get a shock from letting go of something?

Atapuerca – human cannibalism 1 million years ago: what is known about the evolution of human morality over time into the near current era?

I just watched the recent video from Stephen Milo on human life 1 million years ago. He mentions cannibalism evidence across multiple events. That has me thinking about morality in isolated groups and how it might have evolved or could evolve differently....

Does stranger matter violate thermodynamics?

I’m just curious.Strange matter, according to my research, is a perfect state of matter with perfect density, etc. If it is like this, does that also mean that it violates the law of entropy?Because let’s see, if it converts matter around it into stranger matter, and after that it doesn’t react with anything else, I mean...

What mechanism is the source for Earth's Nitrogen?

I recall an explanation of the formation of Jovian moons on the Harvard Smithsonian “CfA Colloquium” YT channel that casually mentioned how various elements freeze out of the solar wind forming ices, and this is the mechanism that allows formation of moons with large amounts of water and elements that are not found in larger...
