Bio-composite combines hardness of aluminum with toughness of bone

When it comes to plant-based materials, many people may picture something that's "green" but not very robust. Such is not the case with a new MIT-designed composite, however, which is claimed to be as hard as aluminum and as tough as bone.

New technique illuminates micro-cracks in ordinary concrete

Although concrete can be altered in order to help tiny cracks show up before they become catastrophic, scientists have now discovered that regular concrete does the job pretty well itself. It just needs a coat of ordinary paint, and a light source.
