VACCINATING people against swine flu may be a lot easier than anyone dared hope, as it turns out that people have an unexpected degree of immunity to the pandemic now sweeping the world.
A seasonal flu in the same H1N1 family as the pandemic virus has been circulating since 1977, but until now it was thought that this seasonal virus did not induce immunity to the pandemic strain.

Secrets of insect flight revealed
Researchers are one step closer to creating a micro-aircraft that flies with the manoeuvrability and energy efficiency of an insect after decoding the aerodynamic secrets of insect flight.
Dr John Young, from the University of New South Wales (UNSW) in Australia, and a team of animal flight researchers from Oxford University's Department of Zoology, used high-speed digital video cameras to film locusts in action in a wind tunnel, capturing how the shape of a locust's wing changes in flight. They used that information to create a computer model which recreates the airflow and thrust generated by the complex flapping movement.

Taiwan Scientist develops Earthquake Early Warning System
A Taiwan scientist has made an earthquake early warning system, which will allow public a crucial 15-second warning before quake causes destruction.
The system depends on seismic waves, which move horizontally as well as vertically. The device detects and analyses these vertical waves, which travel faster.

NASA Testing Breakthrough In Water Safety
NASA and University of Utah chemists are developing advanced tech for testing the drinkability of water.
The process just began a six month run aboard the International Space Station. Water will be sampled either from the Space Station's or Shuttle's galley using a syringe. It is then forced through a chemically-imbued membrane which changes color based on toxicity.

IAI to Supply Self-Protection System for Military and Civilian Planes
ELTA Systems Ltd., a group and wholly owned subsidiary of Israel Aerospace Industries (IAI), has been awarded a contract to supply its self-protection systems, Flight Guard, for commercial planes in Israel. Contracts for various customers in Israel and abroad for the self-protection systems are estimated to be valued at tens of millions of dollars, over period of years. This is the only system to be tested and authorized by the Israel Civil Aviation Authority (ICAA).

Boeing Flies Harpoon Missile With Updated Guidance Control
A Boeing [NYSE: BA] Harpoon Block II missile equipped with a redesigned Guidance Control Unit (GCU) flew for the first time in a test conducted on Sept. 10. It was launched from the USS Princeton off the coast of California and scored a direct hit on a land-based target on San Nicolas Island, Calif.
The new GCU, which controls most of the missile's functions, incorporates a Selective Availability Anti-Spoofing Module (SAASM) Global Positioning System (GPS) receiver to improve GPS security. In addition, the GCU resolves obsolescence issues and can accommodate possible future implementation of a data link for network centric operations.

Scientists Create First Ever Magnetic Gas
For decades, scientists have debated whether or not gasses could display the same magnetic properties as solids. Now, thanks to some MIT scientists, they know the answer is a freezing cold yes.
MIT researchers have observed magnetism in an atomic gas of lithium cooled down to 150 millionths of a degree above absolute zero.

Microvision commercially launches the first laser picoprojector
Microvision (Redmond, WA) has commercially introduced the world's first laser-based picoprojector, called SHOW WX, which is based on the company's proprietary PicoP display-engine technology.
The Microvision picoprojector uses the laser-based PicoP display engine that delivers large, colorful, bright, and vivid images that are in focus regardless of projection distance.

U.S. Air Dominance Eroding
The U.S. military’s historic dominance of the skies, unchallenged since around spring 1943, is increasingly at risk because of the proliferation of advanced technologies and a buildup of potential adversary arsenals.

CSBA outlines B-3 Next Generation Bomber
Thomas Ehrhard, of the Center for Strategic and Budgetary Assessments, has published a fascinating monograph today with a recommended long-haul strategy for the US Air Force. The paper covers a lot of ground, but contains a particular focus on the USAF's deeply classified plans to start fielding a next-generation bomber force within the next 10 years. Ehrhard, who previously helped resuce the US Navy's X-47B program from cancellation, proposes his ideal strategy for a notional B-3 next generation bomber force of 130 aircraft, with a $16 billion development bill and a flyaway cost per aircraft of about $425 million.
