Deep-Space Positioning System

NASA's Jet Propulsion Laboratory (JPL) has developed a compact, low-power, self-contained instrument that provides the equivalent of GPS throughout the solar system without the aid of an artificially provided infrastructure. The state-of-the-art X-ray navigation instrument is also able to determine the position of a...

The Reality of Application Security: Scare Tactics or Genuine Threat?

Guardians of application security have perhaps become slightly immune to the fearful messages of cybersecurity vendors. The combination of ‘Big Data’ with an exponentially growing Internet of Things (IoT) would seem to provide the perfect storm conditions for the...

Question of the Week : Communications
In five years, will light-enabled Wi-Fi "find a home?"

This week’s Question: A PhD student at Eindhoven University of Technology has developed a way of using infrared rays to carry wireless data to a laptop or smartphone. The wireless data comes from central "light antennas" that could, for example, be mounted on a ceiling to direct the rays...
