Scientific American did a good piece of limb regeneration back in April 2008(Regrowing Limbs: Can People Regenerate Body Parts? Preview - http://www.scientificamerican.com/article.cfm?id=regrowing-human-limbs)
Key points are that salamanders are best at complete limb regeneration but humans (and many other animals) scar instead of regenerating. However, if we turn off the scar system and prime the regeneration system, we may be able to regenerate whole limbs, too. One of the neat points made in the article is that salamanders cells seem to know how to re-build the lost limb with first growing a "baby" version. In other words, lose your limb and an "adult" one will regenerate without you having to wait 15 years for it to grow to the right size.
I'm no expert, but I seem to recall from an article that I read that the pressure of "a million atmospheres" was created by tightening the screws on the anvil by hand. If that's true, it hardly seems like a practical setup for storing and retrieving massive amounts of energy.
Isn't the idea of quantum crypto and even crypto in general seriously in doubt given the advent of the "First Electronic Quantum Processor" (see recent/. posting) Granted, the first processor is only 2qb, but once it's scaled to 8qb won't it be able to crack pretty much any crypto?
