The U.S. Army has announced the Apps for the Army (A4A) challenge, a three-month outreach to the service’s active duty, National Guard and civilian employees that will award as much as $2,000 to the top entries.

I'm a fan of all things Discovery: Animal Planet, TLC, and of course the Science and Military channels. So I'm particularly excited about the Discovery News iPhone application.

Brig. Gen. Russell J. Handy, USAF, has been named director, Air Component Coordination Element, U.S.

NATO is transitioning its satellite communications infrastructure from an ownership- and capability-based “bent pipe” arrangement to a more fluid, service-led approach. The challenge for the alliance now is in making plans and provisions for that new capability, which aims at providing a guaranteed ability to obtain the required services to meet collaborative communications needs in space and on the ground.

Researchers are pursuing advances in radio antenna technology to build communication equipment into body armor and to offer more capable and efficient methods for countering roadside bombs. Virtual modeling techniques incorporating developments in materials science currently are testing and verifying prototype equipment before physical testing begins. This combination of cutting-edge research and simulation has rapidly matured these antenna technologies and prepared them for initial operational evaluations.

Strategic efforts to access top executives’ computers and to steal source code and intellectual property are taking cybercrime beyond simple financial theft. Criminals and foreign organizations are launching more sophisticated and targeted phishing and malware attacks, resulting in more prevalent infiltrations in 2009. Cybercriminals often target social media sites, such as Twitter and Facebook, and use an individual’s personal data to fool friends and colleagues into revealing valuable personal and corporate data.

The convergence of information technology and voice communications is prompting another merger—this one between government and industry. The establishment of the National Cybersecurity and Communications Integration Center late last year is the first step in unifying the effort to keep U.S. information networks and infrastructure secure and to respond immediately in case of attack. The center increases the U.S. government’s ability to detect, prevent, respond to and mitigate disruptions of voice and cyber communications.

Digital natives probably don’t remember how home TV viewers had to manually adjust “rabbit ears”—those odd-shaped dipole antennas that sat atop a TV sprouting wires and sporting any number of dials to turn in the hope of improving the picture. But when a recently uncovered use for an alloy comprising gallium and indium becomes widespread as the go-to material for antennas, the newest antennas may be able to adjust themselves without a human hand. Although only in the second stage of research, the combination of these well-known materials already has demonstrated that when bent and twisted, antennas return to their original shape; when cut with a razor, they heal.

Lisa N. Wolford grew up loving water sports. A former competitive swimmer, she worked as a lifeguard as a teenager and young adult. Later she took up motor boating, kayaking and sailing as well as jet and water skiing. But probably because she came of age in land-locked Nebraska, Wolford never did learn how to surf. That proved no hindrance later in life. As a federal information technology executive, the former U.S. Marine Corps radio operator figured out how to catch a big wave and ride it to success.
