For some time scientists have tried to make nanosized artificial bone materials using various methods, And have recently turned their attention to mineralised collagen, a nanoapatite/collagen composite. This material is highly biocompatible and has the nanostructure of artificial bone. It could be used in bone grafts and bone-tissue engineering, among other applications."

Reading the modified image crashed the readers, which suggests they could be vulnerable to a code-injection exploit that might, for example, reprogram a reader to approve expired or forged passports."
