Smart Self-Service Scales 279

Roland Piquepaille writes "German researchers have developed intelligent self-service scales for supermarkets, able to recognize fruit or vegetables placed on them (photo). The scales automatically recognize the item being weighed and ask the customer to choose between only those icons that are relevant, such as various kinds of tomatoes. The scales are equipped with a camera and an image evaluation algorithm that compares the image of the item on the scale with images stored in its database. Store managers can add items to the database. The scales are now being tested in about 300 supermarkets across Europe."

The First Paper-Based Transistors 177

Roland Piquepaille found news of research out of Portugal that has resulted in the first paper-based transistors (the original article is less informative than Roland's blog). More precisely, they've made the first field effect transistors (FET) with a paper interstrate layer. According to the research team, such transistors offer the same level of performance as 'state-of-the-art, oxide-based thin film transistors produced on glass or crystalline silicon substrates.' Possible applications include disposable electronics devices, such as paper displays, smart labels, bio-applications or RFID tags. The research will be published in IEEE Electron Device Letters in September.

Giant Snake-Shaped Generators Could Capture Wave Power 432

Roland Piquepaille writes "UK researchers have developed a prototype of a future giant rubber tube which could catch energy from sea waves. The device, dubbed Anaconda, uses 'long sea waves to excite bulge waves which travel along the wall of a submersed rubber tube. These are then converted into flows of water passing through a turbine to generate electricity.' So far, the experiments have been done with tubes with diameters of 0.25 and 0.5 meters. But if the experiments are successful, future full-scale Anaconda devices would be 200 meters long and 7 meters in diameter, and deployed in water depths of between 40 and 100 meters. An Anaconda would deliver an output power of 1MW (enough to power 2,000 houses). These devices would be deployed in groups of 20 or even more providing cheap electricity without harming our environment."

New Sensor Finds Leaks in Spacecraft 115

Roland Piquepaille writes "With financial support from NASA, Iowa State University (ISU) engineers have developed a sensor to quickly find leaks in a spacecraft. This sensor locates an air leak by listening to the noise generated by the air rushing out of the leak and includes an array of 64 elements that detects vibrations as they radiate along the spacecraft. Because astronauts cannot hear the noise caused by escaping air, NASA needed to design a system to help them. As one ISU researcher said, 'NASA wants to be able to find these leaks. Fixing them is easy. But the question is, "Where is the leak?"' Now that this sensor has successfully been tested on the ground, NASA is evaluating a proposal to build a prototype of the leak detection system for future missions.

The History of the Federal Reserve 514

Michael J. Ross writes "Money plays a key role in modern life; in fact, for some people, nothing is more important than acquiring more of it. Yet most people do not know what money really is, how it is created, how its supply is expanded and contracted, and who benefits from those changes. In the United States, the central figure in this ongoing drama, is our central bank, the Federal Reserve, whose history, power, and effects are explored in G. Edward Griffin's fascinating book The Creature from Jekyll Island: A Second Look at the Federal Reserve." Read on for the rest of Michael's review.

Jack Valenti, Dead at 85 650

saforrest writes "Jack Valenti, a man whose influence in both Washington and Hollywood was profound, died today at age 85. He first became famous as special assistant to Lyndon Johnson: he can even be seen in the famous photo aboard Air Force One. In 1966, he quit this job to become president of the MPAA, from 1966 to 2004."

Submission + - "Dark Side" of the H1-B Program

TheGrapeApe writes: Froma Harrop examines the "Dark Side" of the H1-B Visa program, and the subtle ways that corporations are using it to dismantle and extract American programming, graphic design and other service-sector jobs to overseas economies in this piece from the Seattle Times:

Ron Hira has studied the dark side of the H-1B program. A professor of public policy at the Rochester Institute of Technology, he notes that the top applicants for visas are outsourcing companies, such as Wipro Technologies of India and Bermuda-based Accenture.

The companies bring recruits in from, say, India to learn about American business. After three years here, the workers go home better able to interact with their U.S. customers.

In other cases, companies ask their U.S. employees to train H-1B workers who then replace them at lower pay. "This is euphemistically called, 'knowledge transfer,' " Hira says. "I call it, 'knowledge extraction.' "

Feed The Origin Of The Brain Lies In A Worm (sciencedaily.com)

Researchers find that the vertebrate nervous system is probably much older than expected. The study suggests that the last common ancestor of vertebrates, insects and worms already had a centralised nervous system resembling that of vertebrates today.

Submission + - The grave of Jesus (and his son) found

Firmafest writes: "Movie producer and director James Cameron is expected to hold a press conference Monday morning to announce that he has found the grave of Jesus Christ, as well as Judah, the son of Jesus. According to a blog on Time-blog.com the man who brought you 'The Titanic' is back with another blockbuster. This time, the ship he's sinking is Christianity. The findings will be documented in a 90 minutes documentary to be shown on Discovery channel. The tomb was found 20 years ago, but hasn't been confirmed until now — or did they just wait for the right time before going public?"

Adobe To Release Full PDF Specification to ISO 275

nickull writes "Adobe announced it will release the entire PDF specification (current version 1.7 ) to the International Standards Organization (ISO) via AIIM. PDF has reached a point in its maturity cycle where maintaining it in an open standards manner is the next logical step in evolution. Not only does this reinforce Adobe's commitment to open standards (see also my earlier blog on the release of flash runtime code to the Tamarin open source project at Sourceforge), but it demonstrates that open standards and open source strategies are really becoming a mainstream concept in the software industry. So what does this really mean? Most people know that PDF is already a standard so why do this now? This event is very subtle yet very significant. PDF will go from being an open standard/specification and de facto standard to a full blown de jure standard. The difference will not affect implementers much given PDF has been a published open standard for years. There are some important distinctions however. First — others will have a clearly documented process for contributing to the future of the PDF specification. That process also clearly documents the path for others to contribute their own Intellectual property for consideration in future versions of the standard. Perhaps Adobe could have set up some open standards process within the company but this would be merely duplicating the open standards process, which we felt was the proper home for PDF. Second, it helps cement the full PDF specification as the umbrella specification for all the other PDF standards under the ISO umbrella such as PDF/A, PDF/X and PDF/E. The move also helps realize the dreams of a fully open web as the web evolves (what some are calling Web 2.0), built upon truly open standards, technologies and protocols."

Submission + - World's first 4G mobile system is in China

fmnews writes: "China has launched the world's first fourth-generation (4G) mobile communication system in Shanghai. The home-grown 4G system provides speeds of up to 100 mbps in wireless transmission of data and images many times faster than that of current mobile technology. The rollout of the trial, which has cost $19.2 million, is a milestone in the development of China's 4G technologies, the official 'China Daily' reported. "It testifies that the technology we've developed is feasible and brings us one step closer to put it into commercial use," a leading expert involved in the programme, You Xiaohu said. China initiated the B3G (Beyond 3G)/4G research project in 2001 under the label Future Technology for Universal Radio Environment, or FuTURE Project. http://visible.mobi/readMore.php?newsId=1844&story =World's%201st%204G%20mobile%20system%20is%20in%20 China&case=1"

Blue Crab Nanosensor to Fight Terrorism 106

Roland Piquepaille writes "A substance found in crab shells called chitosan has very useful properties. For example, it has been used in bandages to stop bleeding. But now, researchers at the University of Maryland have used the chitosan from blue crabs living in Chesapeake Bay as a component of a nanoscale sensor system which could save many lives in the future. These blue crab nanosensors will be used to improve security in airports, hospitals and other public locations by detecting tiny amounts of explosives or chemicals in air and water. Read on for additional references and pictures of these blue crab nanosensors."
