'Sharkitecture:' A nanoscale look inside a blacktip shark's skeleton

Using synchrotron X-ray nanotomography with detailed 3D imaging and in-situ mechanical testing, researchers are peering inside shark skeletons at the nanoscale, revealing a microscopic 'sharkitecture' that helps these ancient apex predators withstand extreme physical demands of constant motion. After hundreds of millions of years of evolution, scientists can now finally see how shark cartilage works at the nanoscale -- and learn from them.
