Case Western Reserve University engineers hit pay dirt with clay mixture

A watery, mud-like substance has hit pay dirt for Case Western Reserve University engineering professor David Schiraldi and his research group. The researchers have created a line of patented foam-like and environmentally friendly polymers, called clay aerogel composites that can take on the s...

Here's venom in your eye: Spitting cobras hit their mark
