Air Force Office of Scientific Research and National Science Foundation-funded professor, Dr. Xiang Zhang has demonstrated at the University of California, Berkeley the world's smallest semiconductor laser, which may have applications to the Air Force in communications, computing and bio-hazard detection.
The semiconductor, called a plasmon, can focus light the size of a single protein in a space that is smaller than half its wavelength while maintaining laser-like qualities that allow it to not dissipate over time.

IP routing takes one giant leap into space
A joint venture between the Defense Department, Cisco and Intelsat reached a major milestone with the launch of the Intelsat 14 (IS-14) satellite that contains an Internet router designed for the rigors of operation in space. The router onboard IS-14 is intended to demonstrate Internet Routing in Space (IRIS) capabilities to the military.
The Power of Aggregated Broadband
A growing small or medium-sized enterprise will likely need to scale up its facility's bandwidth. However, making the jump from T1 to T3, for example, may be more of a leap than it's ready to take. By aggregating bandwidth from multiple broadband connections, a business might be able to get more bang -- and more reliability -- for the buck.
Air Force extends plug-and-play spacecraft
Looking to build strategic satellites in day if need be, rather than months, the Air Force is pushing forward with what it calls plug-and-play spacecraft.
This week it awarded a $500,000 order to Northrop Grumman to begin designing the plug-and-play spacecraft "bus" which will offer standard interfaces for a variety of payload components, much like a laptop computer that immediately recognizes new hardware when it's plugged in.

Swipe Your Credit Card on a Cell Phone
With a small card reader that attaches to a cell phone, a new company is making it easier for small businesses and even individuals to accept credit card payments. The San Francisco start-up, called Square, which opened just last week, is headed by Twitter cofounder Jack Dorsey.
New platinum compound shows promise in tumor cells
MIT chemists have developed a new platinum compound that is as powerful as the commonly used anticancer drug cisplatin but better able to destroy tumor cells.
Lotus leaf solar cells soak up more power
SOLAR cells have an unfortunate habit of reflecting back much of the light that hits them, rather than converting it into electricity. A technique that peppers the cells' surface with nanoscale domes could curb this tendency and improve efficiency by as much as 25 per cent.

Google offers search by sight
Google's first search engine let people search by typing text onto a Web page. Next came queries spoken over the phone. On Monday, Google announced the ability to perform an Internet search by submitting a photograph.
The experimental search-by-sight feature, called Google Goggles, has a database of billions of images that informs its analysis of what's been uploaded.

In the Brain, Seven Is A Magic Number
Countless psychological experiments have shown that, on average, the longest sequence a normal person can recall on the fly contains about seven items. This limit, which psychologists dubbed the "magical number seven" when they discovered it in the 1950s, is the typical capacity of what's called the brain's working memory.

NASA Challenges 350 Rocketeers Nationwide to Aim a Mile High
NASA has invited more than 350 student rocketeers from middle schools, high schools, colleges and universities -- 37 teams nationwide -- to take part in the 2009-2010 NASA Student Launch Projects.
Their challenge is to build powerful rockets of their own design, complete with a working science payload, and launch them to an altitude of 1 mile.
Boeing Unveils New Visual Display for Simulation Applications
The Boeing Company [NYSE: BA] demonstrated its Constant Resolution Visual System (CRVS) for potential customers this week at the Interservice/Industry Training, Simulation and Education Conference in Orlando. CRVS, the company's newest visual display, delivers an immersive environment by providing a high-resolution "out-the-window" view for training systems and for general visualization applications.

Swiss Team Achieves First-Ever Manned Solar Plane Flight
Folks over at the École Polytechnique Fédérale de Lausanne, Switzerland, have been working on a solar-powered plane since 2003. Now, after six years of testing, they have finally managed to get the plane off the ground.
Tunable Terahertz Lasers Could Allow Airport Scanners to Chemically Analyze Substances
An MIT electrical engineer and colleagues have managed to tune a small but powerful laser capable of generating terahertz rays. That could someday lead to airport scanners capable of even better snooping than superheroes.
The laser in question is a quantum cascade laser, which came out of Bell Labs in 1994.

Not Yet For Unmanned, Autonomous Aircraft
Although the U.S. military has fielded many new unmanned aircraft in recent years, the Pentagon is far from sending the last manned war plane into combat, Air Force Lt. Gen. David Deptula said Dec. 3.
As the defense community debates the future of combat tactical aviation, Deptula said during the taping that any possible fielding of a fleet of totally unmanned - and even totally autonomous - combat planes is many years away.
Sensors Improving U.S. Army Logistics
The Army is headed toward increased use of sensors on vehicles and aircraft that predict and report impending system failures, said Lt. Gen. Mitchell Stevenson, speaking at a conference on military logistics.
Those devices are embedded in vehicles and aircraft with the purpose of alerting operators about the health of the vehicle or when a new part is likely to be needed before a failure happens

Comeback of supersonic flight
In the labs and wind tunnels of Cleveland's Glenn Research Center and three other NASA facilities, the prospect of commercial supersonic flight is quietly coming out of mothballs.
Glenn engineers and their counterparts at the Langley, Dryden and Ames research centers are at work devising greener, fuel-efficient and less-polluting supersonic engines.
