One of the limiting factors of remotely-operated vehicles is the fact that, in order for their operators to see what the ROVs' cameras are seeing, the craft have to be tethered to a support ship. Scientists are working on changing that, using lasers to wirelessly transmit video through the water.

Quantum encryption can make data breaches literally impossible, and in a new demonstration of that kind of security, scientists have now used the Chinese satellite Micius to send quantum-encrypted data between China and Austria. That brings the world another step closer to a global quantum internet.
