Cool App-titude: Mashable

April 6, 2010
By Katie Packard

I keep up with all things social media and Web 2.0 related by reading Mashable, one of the largest blogs focused specifically on these topics. Now fans like me can read Mashable on the go with the Mashable iPhone app. The free tool allows users to browse by channel, category, tag or author; share stories via e-mail, Twitter or Facebook; save stories to read offline later; and more. For more information or to download the application, visit the iTunes store. These sites are not affiliated with AFCEA or SIGNAL Magazine, and we are not responsible for the content or quality of the products offered. When visiting new Web sites, please use proper Internet security procedures. In other news, this is Katie Packard's last post to Cool App-titudes and SIGNAL Scape. But never fear, the blog--and the App-titude column--will continue. Future editions will include apps for other mobile platforms, Facebook, and others that catch our attention. We hope you enjoy!

Need for Math and Science Majors Is Out of This World

February 17, 2010
By Henry Kenyon

For my February 2010 article, I interviewed members of the Defense Department's Human Spaceflight Payloads Office and Space Test Program about the experiments they help put into space. The projects impressed me, as did the sources' firm belief in the importance of what they do to help warfighters. At the end of our interview, I asked the gentlemen to indulge me on a personal question: "What would you recommend to a child like my son, who wants to grow up to become, as he calls it, 'a space scientist?'"

Fuel Cell Technology Soars

December 2009
By Henry S. Kenyon

A small unmanned aerial vehicle powered by a fuel cell soon may be soaring over distant battlefields. Lightweight tactical robot aircraft are vital for supplying ground forces with immediate reconnaissance information, but their battery-powered engines limit their operational time. New advances in fuel cell technology will allow smaller, lighter robotic aircraft to stay aloft for 24 hours or more to supply commanders with continuous data.

Heat Ray Warms Up for Operation

April 2009
By Henry S. Kenyon

U.S. troops soon may use a nonlethal directed energy weapon to disperse crowds and protect vital facilities. Operating at ranges beyond conventional small arms, the technology allows military units to protect themselves from demonstrations without resorting to lethal force. The technology has the potential to change how military and law enforcement agencies manage riots and other civil disturbances.
