Scientists are turning humble pond scum into fuel. A research effort seeks to develop techniques to grow algae economically and to convert the oils produced by the tiny plants into biodiesel on an industrial scale.

The U.S. Navy's Combined Enterprise Regional Information Exchange System–Maritime is part of a multinational initiative supporting information exchange among coalition partners. Successful coalition communications systems must be built around capabilities that allow a responsive flow of information without violating the trust or compromising the security interests of participating nations.

The transition to Internet protocol version 6 (IPv6) is not about the protocol but what that protocol will enable. The first step is to have a core backbone in place, and from there, "things start getting exciting and interesting," relates Dr. John W. McManus, deputy chief information officer and chief technology officer, U.S. Commerce Department.

Prevailing in Iraq and in the Global War on Terrorism dominates most military planning today, but other challenges loom on the horizon. One element linking all of these issues is the unconventional thinking it may take to maintain military supremacy and meet the difficulties confronting the Free World.

The U.S. Army and Marine Corps are shouldering the nation's burden in Iraq and Afghanistan, and they are suffering the majority of their casualties from roadside bombs. To dramatically reduce injuries and loss of life caused by fragmentation and blast overpressure, the two services are rapidly fielding 4,000 to 6,000 mine resistant ambush protected (MRAP) vehicles. There is no question that the immediate fielding of these mine-resistant vehicles will help protect our nation's most valuable military assets—service members. But is this the complete answer to a problem?

The Strong May Beat the Weak, but the Smart Defeat the Strong. By Cmdr. Gregory E. Glaros, USN (Ret.)

In his March 2007 SIGNAL Magazine column, Greg Glaros says "There was never a technology they didn't like ...at a cost they could afford."

After five and a half years in which you have entrusted in me a leadership position at AFCEA International, it is now time for me to step down as president and chief executive officer.

A ship sailing inside a building, a periscope view on a PC and F-18 pilots located thousands of miles apart yet flying in formation are just some of the new teaching tools simulators now are enabling for the U.S. Navy. Computing advances and that touch of illusion that only the entertainment industry can create immerse both new and experienced sailors in virtual environments that suspend reality and convince them that what they see, smell, hear and feel truly surrounds them. The opportunities these capabilities offer are melding the Navy's training and operational environments and shrinking the time from learning to doing.

Soldiers are receiving better and more convenient simulated training as developers work to increase the scalability and accessibility of their products. Troops are benefiting from training tools they can load onto personal laptops and take anywhere instead of being forced to visit a major simulation facility. The result is that warfighters no longer have to leave a mission to conduct a simulation or to wait for simulation centers to have an opening on their calendar.
