In the modern day, we’re used to sending messages to people over long distances, usually by way of a phone. But now, scientists at MIT have developed a way to use a laser to beam an audible message through thin air to a person standing on the other side of a room, so that only they can hear it.

The Australian government yesterday passed a bill allowing law enforcement agencies to compel tech companies to hand over encrypted messaging data. The legislation has been broadly condemned with suggestions it could not only harm the Australian tech industry, but undermine encryption worldwide.

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.
