Using precision techniques for making superconducting thin films layer-by-layer, physicists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have identified a single layer responsible for one such material's ability to become superconducting, i.e., carry electrical current with no energy loss. The technique, described in the October 30, 2009, issue of Science, could be used to engineer ultrathin films with "tunable" superconductivity for higher-efficiency electronic devices.

Intel Claims Memory Research Milestone
Intel (NSDQ: INTC) and Numonyx say they have achieved a research milestone in computer memory that could one day lead to a less expensive and higher-performing alternative to the technology used today.
The accomplishment stems from the work the two companies have been doing together on a type of non-volatile memory called phase-change memory, or PCM. The research partners say they have successfully stacked multiple layers of PCM arrays within a single 64 Mb die.

Fermi Telescope Caps its 1st Year with a Glimpse of Space-Time
During its first year of operations, NASA's Fermi Gamma Ray Space Telescope mapped the extreme sky with unprecedented resolution and sensitivity. It captured more than one thousand discrete sources of gamma rays -- the highest-energy form of light. Capping these achievements was a measurement that provided rare experimental evidence about the very structure of space and time, unified as space-time in Einstein's theories.

Metamaterials Arrive in Cellphones
The quest to build more-powerful multiband mobile handsets has gotten a boost from a relatively new class of materials. Called metamaterials, they arespecifically engineered to have properties that do not occur naturally, such as the ability to bend light the wrong way. For manufacturers of mobile devices, recent advances in metamaterials promise a way to shrink size while still retaining multiband functionality.
Yellow Jacket Fuses MASINT, IMINT, UAVs to Hunt IEDs
CenTauri Solutionshas been awarded by the U.S. Department of Defense to demonstrate an integrated UAV-based counter-IED technology. Known as “Yellow Jacket” the $11.7 million program is sponsored by the U.S. Air Force Research Laboratory, (AFRL) in Rome, New York. Such a capability could provide life saving services for military patrols and convoys, by scanning the roads and locations and identifing potential IED threats before the arrival of the forces.
Northrop Grumman Announces Successful G/ATOR AESA System Tests
Northrop Grumman Corporation (NYSE:NOC) today announced a prototype partial array antenna representative of the U.S. Marine Corps Ground/Air Task Oriented Radar (G/ATOR) active electronic scanned array (AESA) has completed successful testing at a company antenna test range in Norwalk, Conn., where all planned test objectives were met. This provides a high degree of confidence that the first EDM fully populated array (currently under integration/test) will likewise be a success.

NASA: Ares I-X rocket damaged in test flight
The booster rocket used in a test flight was badly dented when it fell into the Atlantic because of a deflated parachute, NASA said Thursday.
Asteroid explosion was a whopper for Earth
A space rock explosion earlier this month over an island region of Indonesia is now being viewed as perhaps the biggest object to tangle with the Earth in more than a decade.
Japanese Ship Conducts Successful BMD Test
A Japanese destroyer shot down a ballistic missile target during a seven-minute engagement off Hawaii on Tuesday night, becoming the third Japanese ship to demonstrate an engagement capability using the Aegis combat system.
