This is just weird

Dick move, NASA. Dick move.

Words cannot express how much I want this to be true.

Curiosity: "This is one small maneuver for a robot, one giant high-five to the internet."

On a completely unrelated note that you have  probably heard of already...

Edit:  fixed my grammar

[AlmightyOne]

Well what's wrong with it, since they didn't find any water they just decided to draw a penis, because seriously what else to do.

One big flaw:

We don't use EM impulses. We use ions. Most commonly, K+ and Na+ ions moving into and out of neurons, producing little waves of changing charges (It's more complex, I'm trying to put it imply, since the whole thing needs quite a wall of text).

Basically, no EM radiation or electricity is used. Simply positive ions. Which are sorta the inverse of electricity, since electricity is electrons, which are negative, and positive ions are... positive.

This is so WTF false I don't know what even. It's like listening to my girlfriend reiterating the next big new age guru bullcrap. ARRGHHGHGHBLBL

That is just sad.
Just watched this, I don't know anything about guns or anything but it's just funny.

Buh? That's high-school level Biology, man. How is it false?

I presume for similar reasons that they teach you a lot of nonsense in high school level physics: It's wrong, but fairly close to being right and a lot simpler.

[Bauglir]

It is correct that ions moving around is how nerve impulses propagate. How this makes it not electrical is a mystery to me, since it's pretty dependent on the forces generated by the charges on those ions. A lot of the structures involved are even dependent on voltage, and there's definitely measurable electrical activity (hence, EKGs and stuff).

you probably meant this http://en.wikipedia.org/wiki/Sodium_channel
but you should also note this

As a side effect of the electrochemical processes used by neurons for signaling,
brain tissue generates electric fields when it is active. When large numbers of
neurons show synchronized activity, the electric fields that they generate can
be large enough to detect outside the skull, using electroencephalography (EEG)
[70] or magnetoencephalography (MEG).

since you said this

[MonkeyHead]

Oh god, the lack of Physics knowledge, it hurts! All "electricity" is, as in electric current, is simply a flow of charge, be it electrons as used in circuits, or ions in electrolysis or batteries - positive or negative does not matter, as long as charge is moving. People just assume electricity = electrons, as that is what they are familiar with through exposure to distribution systems.
