Majorana particles may block intruders on sensitive networks in the future - Story
July 30, 2018
The signature of the long-sought-after Majorana particle - a particle that has unusual properties believed to render it resistant to external interference - has been found by a group of researchers led by UCLA and funded by the U.S. Army. What they've found may just be the key to blocking intruders on sensitive communications networks in the future.

Cyberattack attribution: Is it actually a deterrent? - Story
July 27, 2018
As the U.S. Department of Defense (DoD) builds up its cyberwarfare programs, what sorts of cyber ops are North Korea and other nation-state adversaries focusing on? Does attribution or admission of responsibility actually act as a deterrent to other would-be cyberattackers?

Ensuring navigation in GPS-denied environments - Story
November 20, 2017
Global militaries are leveraging multiple technologies and creating augmented solutions to ensure navigation in GPS-denied environments. In this QandA with Troy Brunk, vice president and general manager of Communication, Navigation and Electronic Warfare Solutions for Rockwell Collins Government Systems, he discusses this trend, the history of GPS technology, improvements in Galileo Global Navigation Satellite System (GNSS) solutions, leveraging M-code, and more. Edited excerpts follow.

Shipboard electronics trend both sophisticated and "retro" - Story
September 06, 2017
As one of the world's most sophisticated scalable radar systems is poised to make its debut aboard U.S. Navy vessels, so is a "retro" version of an old approach to ship-to-ship communication. This old-style method enables sailors to use their vessels' signal lamps to text-message each other on handheld devices without knowing Morse code during communication-denied scenarios while at sea.
