What do you get when you combine microorganisms and fiber optics? Mind control over mice and rats.
A fiber optic cable is connected into a living mouse or rat with the spliced genes allowing scientists to expose different neurons to different lights.
An optical fiber backbone (red) provides broadband connections between the central offices and antenna base stations.
Then, the base stations wirelessly transmit 5-mm-wave (60 GHz) signals to customers. Within buildings and homes, the short-range wireless signals can provide high-speed connectivity (faster than 1 Gb/s) for a variety of wireless, high-bandwidth communication devices.
