I have a funny feeling that fusion power plants will have a large amount of nuclear waste over time.
The deuterium and tritium reaction is but one of a few options. It is however the easiest option to realise.
My belief is that more safe and scalable fission research and deployment should be done, waste repositories opened, and when (if) fusion power becomes reasonable, we will have a waste disposal system ready to go for it.
I am sorry if I was implying that fission research should be halted. Again it is my personal opinion that as of now fission is our "best bet".
There is a reason that your opinion is unpopular. It is wrong.
It produces even more radioctive waste than fission, because you have to transform the all the neutreons and other radiation coming out from the reaction, to heat.
I strongly suggest that you read more about nuclear fusion.
The number one problem of humanity is that we are consuming too much natural resources. The availability of a power-source like fusion would increase our consumption even more instead of reducing it.
Why would it not reduce our consumption of resources? When fusion is realised, less coal, oil and natural gas would be required to produce power.
Please everybody stop dreaming of fusion and use your resources (intellectual and monetary) on techonlogies like solar power,....
I put my intellectual and monetary backing behind nuclear fusion, solar power does not spark my interest as I find that too much energy is reflected. This is a personal opinion of my own.
Again, I am being quite serious. If (hopefully when...) the LHC team confirms the Higgs, could they file for a patent on their discovery? The LHC's location (French/Swiss border) might complicate the process, but is it fesible?
I am actually being rather serious. If I can patent a gene, what can't a patent? Is it feasible that I could patent a molecule such as dihydrogen monoxide. Could I patent a elementary particle such as the Higgs?
Hmm, now IANAB nor do I have any real training in the life sciences, however I am under the impression that cancer is essentially unregulated cell growth. Thus I doubt that hibernation would stop it altogether, as for slowing it, I haven't the faintest idea.
Holographic optical tweezers have been around for a bit, however this is the first time that I have seen it done in 3-dimensions. That being said, I am only a second year physics undergrad so it very well may have been done before, yet this is the first I have heard of it.
Further digging led me to theUniversity of Glasgow's Optics Groupd where there is a great deal of information on their project page about optical tweezers. As an aside, I don't suppose anyone has the time to elaborate on the Gerchberg-Saxton algorithm?
Couldn't the ISS be used to study the long term effects of microgravity on humans? That is, if NASA would allow its astronauts to pull longer terms. I do not mean to come across as snide, however, there are some things that the ISS could have proved vital too, however in its current state I would have to agree that the ISS is a white elephant.
However, is private industry insterested in science? As I have said before, private industry in space is good, however there is a place for NASA. I am having great difficulty thinking of a corporation which would greenlight the Kepler Mission or LISA.
Does it really have to be an either/or question?
Yes. If you want cool stuff, you have to pay for it.
Couldn't we cut funding for something else, like say nuclear weapons research/maintenance, ( i mean we could get rid of the nukes, not just stop taking care of them.)? Just get rid of ICBMs all together, i mean, is it all that important that we be able to kill someone in 4 hours instead of 8 hours with a nuclear cruise missile?
No, we cannot cut funding for nuclear weapons research/maintenance. You are lying to yourself if you believe that anyone in Washington would consider purging nuclear weapons from our arsenal. As for cutting maintenance funding, surely you jest. From what I have gathered (though I could be wrong) we really do not know too much about how nuclear weapons age, thus cutting the funding for those who research this would be most unwise.
I suggest you start here. As far as displays are concerned, I cannot help you construct your own, however I have heard that the Private Eye which was produced by the now defunct Phoenix Group was a rather good monochrome display and relatively cheap as well.
I agree with the fact that the jury is still out on the speed of gravitational waves, however most (including myself) expect it to be the speed of light. One can hope that LISA will not experience "budget troubles" as it will measure the arrival times of light and gravity from the same source, settling this question.

Practice, my lord practice! If you cannot read your own handwriting how is a pharamcist suppose to?
Yes it did. There were two versions produced, one with the traditional layout, the other with the punch pads.
Actually, the first Street Fighter implemented a pad which you punched.

The paper can be found at Optics Express. One can also find video of the tweezers in action.
Considerthe Concorde? So it was envisioned in the early 1960's, however, it does look quite stunning, no?
Neutrinos can be detected.

This is why.
Well Doom was originally released in December of 93' and plenty of people still play it.
You do know that Sony has an extensive classical catalogue?
We just aren't getting the same type of benefits from NASA that we once did, it's stagnant and dull.
What crack are you smoking and can I have some?
Tibooks users everywhere demand to know! Seriously, does anyone have any input with regards to this? I am doubting it, but one can hope, no?
Terribly sorry about that.

As with most movies, the book on which it is based is better IMHO.
