No its more general than that, any property of a particle can become entangled except ones that produce a long range field like charge. The position of particles can become entangled as can spin or momentum. Often entanglement is created when a particle in a prepared state is split it into two parts, a downconverted photon (i.e. a photon split by non-linear crystal into two photons of lower frequencies) or a decaying atom, you don't know that properties each part has, but you do know that they have to add up to the previous total.
But you can do more tricks with entanglement, for example, by preforming a measurement on a two particles from two seperate entangled pairs, you can make the other two (potentially millions of miles away from you or each other) entangled with each other. Using tricks like that, we could potentially make a quantum entanglement telephone exchange type system, distrubting entanglement connection to any points in a network as required, but as I said above, you still need a slower than light classical channel as well to do communication.
There are indeed networked, but you still need a classical slower than light channel as well as the quantum entangled particles. So you can't communicated faster than light.
With a n-bit classical channel alone you can
send n-bits obviously. With n units of entanglement you can send nothing
at all, but the entanglement is non-local and
doesn't travel slower than light, indeed you
could say it doesn't travel at all, its already
there.
But with both of the above, you can send 2^n bits of information (note not two times n but 2 to the power of n). Wierd huh.

Its more important than that, that fact clones aren't medically identical or as fit as the orignal, tells us, that there is something we don't know about genetics. Whatever it is, it can cause premature aging and auto-immune disease, that may well mean, that whatever we learn about why clone are unfit, can produce cure for auto-immune diseases and maybe slow down aging.
Perphap the key to clones failure is methylization, the genes in cells can be selectly switched on and off by attacting methyl group to potions of the DNA, how this works, is controlled, and how/if its passed on, is very important unknown of cell biology. In the same way over half the DNA is a cell, is made up of intron sequence that don't code for proteins or gene, however intron a preversed across millions of years of evolution, human share many of the same introns as mice. That means introns have to be doing something important, but unknown. We've much yet to learn about cellular biology and cloning as much to teach us.
Yes indeed it could, since no one has any idea what dark energy is, no one knows weather it may run out in the future.
The standard, and simplest model of dark energy, is just a cosmological constant, which says that every empty piece of vacuum exerts a default repulsive force (creates negative space-time curvature), that idea of actually first inverted by Einstein, with the constant appearing as an arbitary constant of integration in his derivation of the equations of general relavity. In this simplest model obviously dark energy obviously can't change (they'd have to rename to the cosmological variable otherwise:-).
A models where it might run out, is called quintessance, a nice name they made up for a simple scalar field (i.e. a field that has magnitude only, no direction), which has a repulsive effect, models where quintessance decays are very possible.
Thats the mistake all the anti war on iraq people make. Theres no need to take a country over for the oil. If they drill the oil and sell it to us, then we make stuff and sell it them, then we are just as well off as if we owned the oil in the first place. Thats economics. Of course you do have to be good at making something useful or wanted for it to work.
No your can't have a geo-synchronous satellite over the pole, but what you can do is balance a solar sail above the South Pole, using the mommentum of the light of the sun, to balance the earths gravity. The further away the solar sail is, the smaller it needs to be. Now the balance is unstable so you have to carefully control the sail to keep position, but its a simple and useful technic.
Given that antartica was near the equator during the time of the dinasours, i'm expect there to by lots of oil, diamonds, coal, plus your standard exploited minerals in the area. Thus next century when the rest of the earth is mined out, Antartica will be a very important piece of real estate.

I've read Schild's Ladder, very good book, if a little heavy on the physics. If you can handle three page asides on decoherence and charge superselection rules, then Schild's ladders is well, worth a read. Plus its probably they only book that tries to explain loop quantum gravity to layman at present.
Concerns about radiation from the engines? Space is riddled with cosmic radiation of unbelievebly high energy as it is. In a 1 year non nuclear mission to mars astronauts will already exceed there lifetime radiation exposure limit. Reducing the time to a couple of months using a well protected nuclear reaction will actually massively reduce the astronauts radiation exposure.
huh, Quaterions and Octerions aren't commutative but you have well defined inverses. And you can even invert Matrixes of Octerions. P.S. I've miss spelled Quaterions and Octerions, its late.

Previously AMD was working with UMC to develope 65nm 12" wafer chips. But UMC have never been state of the art and IBM is much better bet as a partner.
OO definitely helps modularity, and even splitting responsiblity between programmers, and help maintainity. But reuseability, not really, unless your writing nice well abstracted library functions, your pretty soon find that all the little extra features needed in the code for one project just won't fit with all the little extra features in the other project, and so you some end up to reusability by good old cut and paste.
If your going to allowed to carry guns, at least they should be made so someone else can't use them against you. I am sure some gun nuts here, are going to be against the idea, but i can't imagine a reason why. And yeah it probably won't be secure at first, and they'll be underground gangs rechiping the guns. But it makes it harder for criminals to get guns and that has to be good.
I don't think protein protien interaction is trivial either. Lets assume that both proteins say the same shape. Take one protein rotate it and move it around the other protein in all possible positions and orientations the relavent group action is R(3) tensor O(3), (the group transitions of one body in 3d, times the group of rotations in 3d: six dimensions. proteins are big molecules, for each of the possible orientations and positions you need to calculate the electrical and pauli forces between each atom on the surfaces of one protein with those on the the surface of the other protein to see if the there can be any chemical interaction between the two. This is a heavy ammount of computation. But its worse than that one protein can change the shape of another one making the calculations even more complex.
Proteomics needs the folding problem solved. Protein Protein interaction solved. The inverse folding problem solved (for drug/DNA design). Then DNA-protein interaction, and the interactions with macro sugar molecules. Once you've done all that and have it tabulated in vest lookup tables for common problems and with computation on demand for rarer problems, then you can simulate a single cell.
