Mother-of-pearl -- Classic beauty and remarkable strength
...al by preventing the formation of natural cleavage planes - like those that form the facets of a cut diamond - where a single crystal can easily break. "It is intuitive that a poly-crystal is mechanically stronger than a single crystal, so perhaps that is an advantage for the animal," Gilbert says.

This genus contains some of the worlds most devastating plant and animal pathogens and remains largely a mystery to scientists who do not have ......terials that can be described as individual atomic planes pulled out of bulk crystals. These one-atom thick materials have rapidly become one of the most provocative topics in physics. However, it had remained doubtful whether such materials could exist without the support of a substratum. Now, the resear......n. Snapshots of the specimen obtained in different planes along different directions and at varying time points are assembled into three-dimensional images or movies, which provide insights into the dynamic cellular processes of a living organism.

Conventional wisdom holds that airplanes (airfoils) are more efficient because they travel from point to point with no wasted up-and-down motion.
