Process could someday play a role in creating smart materials and metamorphic devices.

Johns Hopkins computer science graduate students and their professor discovered three security flaws in a popular hobby drone, all of which could which cause the small aircraft to make an 'uncontrolled landing.'

This could serve as a wake-up call so that future drones won't leave the factory until enhanced security features are already on board.
