An ultra-powerful laser can turn regular incandescent light bulbs into power-sippers, say optics researchers at the University of Rochester. The process could make a light as bright as a 100-watt bulb consume less electricity than a 60-watt bulb while remaining far cheaper and radiating a more pleasant light than a fluorescent bulb can.
The laser process creates a unique array of nano- and micro-scale structures on the surface of a regular tungsten filament—the tiny wire inside a light bulb—and theses structures make the tungsten become far more effective at radiating light.

Raytheon-IMI GPS-Guided Mortar Rounds Demo Capability During Tests
A new type of 120 mm precision-guided mortar round hit eight out of nine target areas during a recent U.S. Army-Raytheon Company (NYSE: RTN) cooperative research and development agreement demonstration.
The rounds made by an Israel Military Industries-Raytheon team hit short- and long-range targets, demonstrating greater range than current unguided 120 mm high-explosive mortar rounds in the U.S. Army's inventory.

LM To Develop USAF's Next-Gen Long-Range Radar
The U.S. Air Force has awarded Lockheed Martin [NYSE:LMT] a fixed-price contract for nearly $25 million to develop a prototype for the next-generation 3-Dimensional Expeditionary Long-Range Radar (3DELRR). Lockheed Martin was one of two industry teams placed under contract for the technical development of this new land-based radar.
The Electronic Systems Center at Hanscom Air Force Base leads the acquisition for the new radar. The Air Force plans to replace its entire TPS-75 long-range radar inventory with the 3DELRR, which will detect, identify, track and report aircraft and missiles. Following a 20-month Technical Development Phase, the Air Force has said it intends to competitively award one contract for system development in the 2011 timeframe.

Infrared Fuses Can Send Secret Messages
By combining cutting-edge chemistry with the ancient concept of signaling flares, researchers have made an information-dense fuse that transmits complicated messages as it burns.
The so-called “infofuse” is made from dots of lithium, rubidium and cesium laid on a line of fast-burning nitrocellulose. Different combinations of the metals produce different intensities and wavelengths of light, from visible to infrared. These characteristics can be precisely controlled, allowing the fuses to convey a form of chemical Morse code.

U.S. Military Turns to Twitter for Afghan Hard News
"What are you doing?" For the U.S. military in Afghanistan, the answer to the latest social networking craze seems to be: "Killing Taliban."
U.S. commanders launched their "social networking strategy" for Afghanistan Tuesday, using the hugely popular website Twitter to release information about some of their operations (http://twitter.com/usfora)
Among their first postings about insurgents killed and detained, the military tweeted on Tuesday: "Afghan & coalition forces killed six militants in Paktika Province overnight during a (sic) operation to capture a Taliban commander."

In-depth communication
Raytheon has developed a technology that makes it possible to communicate with a submerged submarine at classified speeds and depths in real time.
The defence technology specialist demonstrated the new technology, called Deep Siren Tactical Paging (DSTP), for the UK's Royal Navy at an at-sea trial.
The Ministry of Defence (MoD) reported that the Deep Siren system demonstrated ‘the first step toward a transformational capability that will change the way we operate submarines in the future’.

Ground control
A highly controllable rocket system with the ability to manoeuvre planetary landers on future space missions has been demonstrated by US engineers.
Project partners Advanced Technology Associates (ATA) and Alliant Techsystems (ATK) have developed a proposed solid-fuel propellant system designed to offer the precision control needed to land NASA's Mars Science Laboratory.
Minneapolis-based ATK is working with NASA's Jet Propulsion Laboratory (JPL) to develop propellants for a low-cost lightweight solid-propellant control system that could be used in payload descent and spacecraft cruise phases for planetary exploration missions.
