Building Better Body Armor With Nanofoams 74
Zothecula writes "Given that scientists are already looking to sea sponges as an inspiration for body armor, perhaps we shouldn't be surprised that foam is also being considered ... not just any foam, though. Unlike regular foam, specially-designed nanofoams could someday not only be used in body armor, but also to protect buildings from explosions."

I can see a lot better use for this than putting it on buildings. How often do buildings in the first world get bombed anyway and what affect will it have on demolishing them when needed? Put them in carparks, as crash barriers and traffic devices, even fencing walls, anything to hold cars back so they cannot cause greater damage to others.

It sure does make for annoying headlines; but 'nanotechnology' is sort of a concept that is doomed by nature to be spread vacuously thin across all sorts of things, both incremental advances and more remarkable stuff.
There probably a material in existence whose bulk properties don't derive from its structure at a fine scale, so the entire history of fields like metallurgy is 'nanotechnology' in a weak sense. On the other hand, though, most of that history, even to the present for economically viable bulk production, is largely messing around with heating and cooling parameters, and throwing various trace impurities into the mix, and then hoping really hard that the right nanoscale structures self-assemble.
The real problem is deciding where to draw the line between 'yeah, it's "nanotech" in the vacuous sense that all materials engineering is' and 'actually "nanotech" in some sense that makes it worthy of the title'...

I'm not American so far be it for me to tell you how to be American.
However there was a T shirt post 9/11 that said "I hope Allah has kevlar" that I feel summed up the sort of can do, batshit insane attitude we expect from Americans and from America.
You guys needs to be be Batman not Commissioner Gordon. We have loads of Commissioner Gordons that work within the rules with all the compromises that implies. Some problems need a rich psycho with an inflexible sense of morality and a load of gadgets.
And in any case the Jokers of this world are going to be blowing up shit no matter what America does. Look at the time line of AlQaeda attacks on the US.
