This is a thread for general questions about biology, chemistry, physics, medicine, environmental science, etc.
Anyway, here's the first question I was wondering.....
How does Tylenol work?

Acetaminophen belongs to a class of drugs called analgesics (pain relievers) and antipyretics (fever reducers). The exact mechanism of action of acetaminophen is not known. Acetaminophen relieves pain by elevating the pain threshold, that is, by requiring a greater amount of pain to develop before it is felt by a person. It reduces fever through its action on the heat-regulating center of the brain. Specifically, it tells the center to lower the body's temperature when the temperature is elevated. Acetaminophen was approved by the FDA in 1951.

Basically its a phase of matter, different from solid, liquid or gas. I'll edit my post with a link to explain what plasma is in more detail, but I can't seem to find the link I want.

Cool...since it's come up I thought I might as well ask, what exactly is plasma? If it's highly ionized gas, how can it be electrically neutral?
