First pilotless F-16

The US air force has test flown an F-16 fighter jet without a pilot on board for the first time in the latest sign of the military’s increasing reliance on drones.

The robotic F-16 flew for 55 minutes with an empty cockpit from a Florida base last week as part of a programme that would see the converted fighter jet used as a target for pilots in training, manufacturer Boeing said.

“It was really amazing to see an F-16 take off with nobody in it,” said Michelle Shelhamer from Boeing, which has adapted the plane for the US military.

The aircraft is one of six “retired” F-16 jets that would be used as aerial targets for fighter pilots training for air-to-air combat, she said.

“They’re basically built to be shot down,” she said. “It’s full-scale, real world, real life, combat training – not with a simulator or anything else.”

NASA awards grant for 3-D food printer

Thtat’s just fantastic age we’re living on! “One of the major advantages of a 3-D printer is that it provides personalized nutrition,” Contractor told. “If you’re male, female, someone is sick—they all have different dietary needs. If you can program your needs into a 3-D printer, it can print exactly the nutrients that person requires.”

NASA is certainly a believer: The six-month grant comes to $125,000. The agency specifically interested in using the 3-D printer to feed astronauts on long space voyages.

“Long distance space travel requires 15-plus years of shelf life,” Contractor said to Quartz. “The way we are working on it is, all the carbs, proteins and macro and micro nutrients are in powder form. We take moisture out, and in that form it will last maybe 30 years.”

International Aviation Exhibition 2012

Airshow China 2012 will take place on Nov. 13-18, 2012, in Zhuhai, Guangdong, China. Since 1996, the Show has been successfully held in Zhuhai in every even-number year for eight sessions.

The China International Aviation Exhibition Center, Zhuhai, China (Zhuhai Airshow Center) occupies an area of 1,300,000 square meters, with 3 car parks and 1 chalet car park, covering 496,900 square meters and can provide 60,000 parking lots.

The static aircraft display area is 408,000 square meters. The area of afforestation reaches 300,000 square meters. The 3 exhibition halls have an area of 43,120 square meters, providing 1,800 package stands. The press center is 11,860 square meters, and it’s a modernized one for news edition, trade negotiation, academic exchange, office working, etc. There are 35 chalets, and each one is 72 square meters, totaling 2,520 square meters.

God Particle

You have probably head about Higgs boson. Scientists working at the world’s largest atom smasher say they have enough evidence of the long-sought-after Higgs boson. What is wxactly Higgs boson and how does it work?

There is a gist of the standard model, developed in the early 1970s: The Higgs boson appeared 13.7 billion years ago in the chaos of the Big Bang and turned the flying debris into galaxies, stars and planets. Our entire universe is made of 12 different matter particles and four forces. Among those 12 particles, you’ll encounter six quarks and six leptons. Quarks make up protons and neutrons, while members of the lepton family include the electron and the electron neutrino, its neutrally charged counterpart. Scientists think that leptons and quarks are indivisible; that you can’t break them apart into smaller particles. Along with all those particles, the standard model also acknowledges four forces: gravity, electromagnetic, strong and weak. Here is the picture found online trying to get illustrated explanation of the subject.

As theories go, the standard model has been very effective, aside from its failure to fit in gravity. Armed with it, physicists have predicted the existence of certain particles years before they were verified empirically. Unfortunately, the model still has another missing piece – the Higgs boson.

“We think the Higgs boson is a manifestation of the fact that the universe is filled with a force that we haven’t been able to detect yet that gives other particles mass,” Lykken told NPR. “It exists for a billionth of a billionth of a billionth of a second, or something like that, and then falls apart into other particles.”

Thus, scientists are in a bit of a quagmire, according to the AP. While they appear to have enough evidence to report the existence of the “God particle,” they still hedge on whether to report “a discovery.” It’s a fine line, indeed, but one that scientists will likely continue to debate.

The Smallest Robot in the World

Bruce Donald and his colleagues, engineers and computer scientists from Dartmouth College have built the smallest robot in the world which is the thickness of human hair and shorter than the sharp point of a thumb tack, integrated in a small package, wireless powered and controlled. However, the robot takes over ten thousand steps a second and continue their motion for over half an hour with no sign of fatigue, with net motion of over one foot in length. That represents over 30 million steps; a human taking that many steps would go over half way around the world.

Features:

60x250x10 micro-meter robot made of polycrystaline silicon and chromium
Utilizes surface micromachining (MEMS) with stress engineering to produce out-of-plane curl.
Monolithic fabrication from poly-silicon includes on-board:
power and control signal pickup,
decoding and state memory (electro-mechanical), and
locomotion and turning.
Two gaits:
forward walking: MEMS Scratch Drive propulsion only, and
turning: Propulsion and Turning Arm both deployed.
12nm average step size.
Operation demonstrated at 16kHz (not an intrinsic speed limit).
Teleoperation alows motion anywhere on a plane.
Moves on an insulated substrate with submerged interdigitated electrodes.
Control is one-wire (plus ground) with four level logic, and is independent of robot position or orientation on substrate surface.

Truly Wireless Battery Invention.

Konarka Technologies, Inc have demonstrated new light-activated Power Plastic Sun Battery, that is flexible, lightweight, lower in cost and much more versatile in application than traditional silicon-based solar cells.

These new materials are made from conducting polymers and nano-engineered materials that can be coated or printed onto a surface in a process similar to how photographic film is made.

Batteries can be useed with devices, systems and structures to have their own low-cost embedded sources of renewable power. By combining energy generation and power consumption within the same device, the battery is truly wireless applications.
