Fuel Efficient Five-Gear Rocket Engine Designed
Roland Piquepaille writes "Georgia Tech researchers have had a brilliant idea. Rocket engines used today to launch satellites run at maximum exhaust velocity until they reach orbit. For a car, this would be analog to stay all the time in first gear. So they have designed a new space rocket which works as it has a five-gear transmission system. This rocket engine uses 40 percent less fuel than current ones by running on solar power while in space and by fine-tuning exhaust velocity. But as it was designed with funds from the U.S. Air Force, military applications will be ready before civilian ones. Here is how this new rocket engine works." -
Robot Dogs Evolve Their Own Language
bab00n writes According to this article at The Engineer Online, researchers led by the Institute of Cognitive Science and Technology in Italy are developing robots that evolve their own language, bypassing the limits of imposing human rule-based communication. The technology, dubbed Embedded and Communicating Agents, has allowed researchers at Sony's Computer Science Laboratory in France to add a new level of intelligence to the AIBO dog. The robot dog has learnt to see a ball and tell another one where the ball is, if it's moving and what colour it is, and the other is capable of recognising it. -
3D Modelling for Kids
An anonymous reader writes "E4engineering has a story on Cosmic Blobs, a 3D modelling tool designed for kids and marketed as a game. Blobs breaks new ground both on the UI side (for instance, the UI has no text whatsoever) and on the modelling side: an object stays smooth as it is pushed and pulled, and animations are automatically adapted to arbitrary shapes. I tried the demo and it's fun, but sometimes unintuitive ( tutorials on the website are useful). I could make animals and get them to hop around with relative ease even though I have no artistic talent. Could this be the way real artists model in the future?" -
Factory Testing of Airborne Laser Cannon Completed
Acid-F1ux writes "Lockheed Martin has completed factory testing of the optical benches for the Airborne Laser's Beam Control/Fire Control (BC/FC) system. The Airborne Laser (ABL) is the first megawatt-class laser weapon system to be carried on a specially configured 747-400F aircraft, designed to autonomously detect, track and destroy hostile ballistic missiles." -
Stopping Malware Before It Hits
SpudGunMan writes "John Lockwood, Ph.D, an assistant professor of computer science at Washington University, and the graduate students that work in his research laboratory, have developed a hardware platform called the Field-programmable Port Extender (FPX) that scans for malware transmitted over a network and filters out unwanted data." -
NVRAM With Disordered Assemblies (Smaller/Cheaper)
chadjg writes " Jim Tour, of Rice University says "Our research shows that ordered precision isn't a prerequisite for computing. It is possible to make memory circuits out of disordered systems." The article on www.e4engineering.com says the team has made "NanoCells", self assembled devices made from gold nanowires and organic conductive molecules. These NanoCells are the first devices of their kind to be made into working microelectronic devices, apparently." Yep. Let an untold number of machines try to create NanoCells, and statistics says you'll find the most efficient kind. -

Ultra High Definition Video
mr.henry writes "Engineers at the Japanese Broadcasting Corporation (NHK) have developed a prototype ultra high definition video (UHDV) system. How good is it? When it was shown to the public, some viewers experienced nausea because of the ultra realistic visual effect of speed without the usual physical sensation of movement. 18 minutes of UHDV takes up 3.5 terabytes." 4,000 horizontal scanlines. Excellent. -
Rearranging Pixels For Performance
tepes writes "From bottomquark, A new method of sub-pixel rendering could make monitors cheaper to produce. ClairVoyante Laboratories developed the PenTile Matrix, which uses five sub-pixels instead of the typical three, to take advantage of the fact that the human eye is more sensitive to blue colors."
