Lightweight, impact-resistant honeycomb structures can sense when they have been damaged
A new form of lightweight, impact-resistant plastic-based 'honeycomb' structures which can sense when they have been damaged could find use in new forms of 'smart' prosthetics and medical implants, its inventors suggest.

Researchers flip the motion of electrons on ultrafast time scales without slowing them down
To change the direction of motion of a massive object, such as a car, it has to be slowed down and brought to a complete standstill first. Even the tiniest charge carriers in the universe, the electrons, follow this rule. ...
