Why Are Eggshells So Strong?

By Kate Stone @GotScienceOrg Anyone who has a tried to squeeze a chicken egg from end to end knows how strong eggshells are. Not much in nature mineralizes as quickly as a bird egg. How is it that fertilized chicken eggs manage to resist fracture from the outside while, at the same time, can be broken open from the inside by a tiny chick? It’s all in the eggshell nanostructure, according to a new study led by McGill University scientists and published in the journal Science Advances. For millions of…

Nanostructured Honeycomb Creates Electricity from Light

By Jonathan Trinastic @jptrinastic Zoom in to the nanometer scale—less than the width of a human hair—and you might think the new device designed by a team of scientists led by Lei Zhang is a honeycomb. Upon closer inspection, you would find that the hexagonal structure is made of gold and that a long string of organic molecules winds up and down through each hexagonal space. And one more thing: this device, so perfectly structured in the world of atoms and molecules, can create electricity from light. These researchers from…
