Back in 2010, Sonitus Technologies introduced a novel in-mouth hearing aid called the SoundBite. Now the US Department of Defense has awarded the company a contract to develop a wireless two-way comms system that clips to a user's back teeth.

MIT's Translational Acoustic-RF (TARF) system uses a combination of acoustics and radar to allow messages transmitted underwater to be directly received in the air without the need for any sort of physical link. The technology holds the promise of making the "silent world" not so silent.

Adapting a laser system called Lunar Laser Communication Demonstration that was used to transmit data between lunar orbit and the Earth, MIT's Lincoln Laboratories is developing a way for underwater workers and machines to communicate more effectively with one another.

It’s an unfortunate truth that weapons and explosives in public places are an increasing problem. But many screening technologies are bulky and expensive, and require staff to operate. Now a new study has found a way to tap into a type of signal that’s already ubiquitous in public places – Wi-Fi.

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.

While it is possible for video bloggers to do multi-camera productions, they pretty much have to record everything with every camera, then go back and edit between them. The Cutbox Studio system, however, allows users to cut live between three included cameras.

Plain old video calls could soon be made to look very outdated, thanks to new research coming out of Queen's University in Ontario. A team there has produced a 3D teleconferencing system called TeleHuman 2, which enables real-time holograms of people to appear in any location.

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.
