I'm like Phi for All. When I lay down I usually contemplate some of the last things I've done. I'd guess that it typically takes anywhere from 30-45 minutes for me to fall asleep. I remember finding this annoying as a kid. I'd spend the night with some friends and they'd all be asleep within 5 minutes of laying down. Then I'd spend an hour trying to fall asleep amidst their snoring.

I looked a little on google. It seems as if ionotropic glutamate receptors are ligand gated ion channels. When glutamate is released from neighboring cells, it binds to the receptor which opens the channel. Ions can then rush in or out of the cell which causes a depolarization. It looks like the channel is divided into five subunits. Remember that primary structure is the linear amino acid sequence of the protein. Secondary structures would be B-pleated sheets or alpha helices, which form due to hydrogen bonding. Tertiary structure of the protein is a complete comformation of a subunit of the protein. All four weak interactions are involved with this folding: ionic, Van der Waals, hydrogen bonding, and hydrophobic interactions. Covalent bonds also help stabilized this structure. They form between the sulfur atoms in adjacent cysteine molecules. The tertiary structure is responsible for the protein subunits behavior. Quaternary structure is the whole protein, including all the subunits. Here's a great link: http://www.bris.ac.uk/Depts/Synaptic/info/glutamate.html

I'm not sure about the first part of your post, it's a little beyond what I've read so far. Ligand gated ion channels are transmembrane channels that allow ions to flow in or out depending on equillibrium. The channels are open and closed by the ligands, which change the conformation of the protein.

That would be why it's in General Discussion. It's fun to talk about random things, thats what GD is for.

Uhh, check your history books. The president does make some decisions, but see who passes the laws.

My birthday is on June 7th, so I'm just going to go ahead and call myself 21 21/m/US

Booo, when did we start becoming anti-opinion nazis? We may disagree just like any other user, but you won't get in trouble for it. BE LIKE SAYONARA AND TELL US WERE WRONG PLEASE>

The opposite also applies. A stick? A stone? A kitchen kinfe? These are all things that can cause harm. Where does freedom begin and end? My handgun isn't putting anyone in danger just lying there. Neither is my printner, unless I beat someone over the head with it.

Yea. In intelligence's case it was something like this: Intelligence: "Yea i'm going to create a biology forum where we can ridicule the weak religious mind" (3 weeks later he's banned and the user BiologyForums signs up) Biology Forums: "Hey join my biology forum. Oh, and no theists on the boards please. By the way, I'm not intelligence."

remember kids, 8 bits = 1 byte.

R U N. seriously, take off sprinting.

They're gone for good.

Indeed, most of them were guilty of mulitple offenses.

Intelligence was banned because of defamation of character and disrespect to forum leaders. A week later he was back on a different name to spam his new website. Hahnemannian444 was banned for defamation of character despite several warnings. Timokay was banned for flooding the forums with vulgarity. I think he was either Hahnemannian444 or a close friend. Zarkov and Adam are the kings of psuedoscience. The royal family, if you will. I believe they were both banned for reasons other than spewing trash [probably got mad and lashed out at someone], although that was part of it.

Hydrogen behaves somewhat like a halogen in that it only needs one more electron to fill it's valence shell.

An airplane is still subject to earth's rotation even in flight. For example, if you throw a ball up inside a moving car, the ball is stationary relative to your fixed point inside the car, even though the car is moving. If you throw a ball up, it doesn't suddenly shoot backwards because you're rotating away! (if so it would fly back at an apparent ~800 mph!) Let's assume the earth is rotating around 800mph counter-clockwise at one point [if measured from space]. If an airplane takes off from this point and fly's AGAINST the earth's rotation at 400mph, the same observer in space will see the airplane actually flying with the earth's rotation, but 400mph slower, so the earth is rotating under the airplane. Likewise if an airplane takes off and flies with the earth's rotation, an observer in space would calculate the airplanes speed to be the 800mph (earth's rotation) + 400mph(airspeed). Bottom line: an airplane is still rotating with the earth just like a ball thrown inside the car is still moving with the car.

Hahnemannian444, Intelligence, Timokay were also infamous in their day.

The warning system isn't even installed anymore

I doubt that was all it was.
