Cracking eggshell nanostructure: New discovery could have important implications for food safety

How is it that fertilized chicken eggs manage to resist fracture from the outside, while at the same time, are weak enough to break from the inside during chick hatching? It's all in the eggshell's nanostructure, according ...
