Twisting puts the brakes on light in a vacuum

The speed of light is a universal constant, but, according to scientists at the University of Ottawa, not that constant. A team of researchers led by assistant professor Ebrahim Karimi has discovered that twisted light traveling through a vacuum moves slower than the speed set by Einstein's theory of relativity, which has implications for quantum computing and communications.Read More

​Simplified system could allow for better robot-human communications

A new system, developed by researchers at MIT, could provide a more streamlined way for robots to communicate with humans in difficult situations, including during emergency response operations. The new model cuts down the necessary communications made by a robot team member by 60 percent, significantly reducing the barrage of data that its human counterpart has to deal with.

First high speed laser communication satellite set for launch

Space-based laser communications are moving out of the testing phase and into orbit as the first satellite in the European DAta Relay System (EDRS), or SpaceDataHighway, prepares for launch at the end of January. Likened to having a fiber optic cable in space, the 1.8 Gigabit per second system is a joint public–private partnership between Airbus Defence and Space and ESA that will act as a relay system between ground stations, satellites, and aircraft.

DARPA wants to make airborne communications more stable

Military airborne communications can be tricky. Not only do they need to overcome attempted disruption from hostiles, but also tackle the difficulties in getting different systems to work together. DARPA is looking to improve things, soliciting proposals to get both manned and unmanned systems communicating faster, more securely and in spite of enemy jamming attempts.Read More

Asteroid Impact Mission sets sights on new laser communications record

Laser-based communications has the ability to beam enormous amounts of data at high speed, but the use of this technology in space is still in its infancy. To help push things along, ESA’s proposed Asteroid Impact Mission (AIM) will carry out a record-setting demonstration of space laser communications across a distance of 75 million kilometers while orbiting a binary asteroid.Read More

TALONS effectively gives ships of all sizes skyscraper-tall masts

Warships are only as effective as far as they can see, so DARPA's Towed Airborne Lift Of Naval Systems (TALONS) research effort is aiming to extend their horizons by giving them a crow's nest 1,500 ft (457 m) tall by way of a towed parafoil. A TALONS prototype recently completed sea trials off the US East Coast as part of a project to provide ships of every size with better long-distance communications and situational awareness.
