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.
"Necessity is the mother of invention" is a silly proverb. "Necessity
is the mother of futile dodges" is much nearer the truth.
