Another fascinating research story from University of Washington. I saw this article on Washington Post’s Web site that I had to share.

“Move over, Bionic Man. Engineers at the University of Washington in Seattle have come up with a nanotech device that Steve Austin would have loved: a contact lens that displays images, letting a person surf the Web, read e-mail, scan a spreadsheet or play a video game, all without using a computer screen.

The lens has not undergone human trials, but it has been tested on rabbits for up to 20 minutes without ill effects.”

The research activities at the University of Washington (UW) in Seattle are often fascinating. I just read the other day that the UW, along with researchers from Harvard and UMass Amherst showed how it is possible for someone to extract patients’ private medical infromation from implantable devices. Not only that, but it is also possible to reprogram the medical settings without patients’ approval or knowledge.

The research has been reported widely in the medical community and in the press. According to the uwnews. org “In computer laboratory bench tests, the research team used an inexpensive software radio to intercept and capture signals sent from the implantable device. They were able to obtain detailed information about a hypothetical patient, including name, diagnosis, date of birth and medical ID number. Researchers could determine the make and model of the device and access real-time electrocardiogram results as well as data on the hypothetical patient’s heart rate and cardiac activity.”

Jason Hiner, the Executive Editor of TechRepublic has written an interesting article Prediction: Microsoft will leapfrog Vista, release Windows 7 early, and change its OS business in which he states that “Microsoft will ultimately try to quell the embarrassing Windows Vista debacle by making a bold move with Windows 7 to win back customer loyalty and generate positive spin for its most important product.” He goes on to say that “My prognosis is that Microsoft will use smoke and mirrors to conjure up an early release of Windows 7, the next edition of the world’s most widely-used operating system. Then they will quietly and unofficially allow IT departments to migrate straight from Windows XP to Windows 7.”

Check out his prediction and the reasoning behind why in his opinion Microsoft will leapfrog Vista and change its OS business.

Google, the world’s most popular search engine, has quietly deleted more than 100 controversial sites from some search result listings. Absent from Google’s French and German listings are Web sites that are anti-Semitic, pro-Nazi or related to white supremacy, according to a new report from Harvard University’s Berkman Center. Also banned is Jesus-is-lord.com, a fundamentalist Christian site that is adamantly opposed to abortion.

Google confirmed on Wednesday that the sites had been removed from listings available at Google.fr and Google.de. The removed sites continue to appear in listings on the main Google.com site.

The Harvard report, prepared by law student Ben Edelman and assistant professor Jonathan Zittrain, and scheduled to be released Thursday, is the result of automated testing of Google’s massive 2.5 billion-page index and a comparison of the results returned by different foreign-language versions. The duo found 113 excluded sites, most with racial overtones.

“To avoid legal liability, we remove sites from Google.de search results pages that may conflict with German law,” said Google spokesman Nate Tyler. He indicated that each site that was delisted came after a specific complaint from a foreign government.

German law considers the publication of Holocaust denials and similar material as an incitement of racial and ethnic hatred, and therefore illegal. In the past, Germany has ordered Internet providers to block access to U.S. Web sites that post revisionist literature.

France has similar laws that allowed a students’ antiracism group to successfully sue Yahoo in a Paris court for allowing Third Reich memorabilia and Adolf Hitler’s “Mein Kampf” to be sold on the company’s auction sites. In November 2001, a U.S. judge ruled that the First Amendment’s guarantee of free speech protects Yahoo from liability.

Google’s battles
The Harvard report comes as Google is becoming increasingly embroiled in international political disputes over copyright and censorship. China blocked access to Google last month.

Google was criticized in March for bowing to a demand from the Church of Scientology to delete critical sites from its index. In a response that won praise, Google replied by pledging to report future legal threats to the ChillingEffects.org site run by law school clinics.

As Google has become the way more and more people find information on the Internet, it has also become an increasingly visible target for copyright complaints about cached information and allegedly infringing links. ChillingEffect.org’s Google section lists 16 requests or legal threats the company has received in the past three months. One Google competitor and critic even suggested that the wildly popular search engine be transformed into a government-controlled “public utility.”

Here are some highlights from an interesting research news as reported by the University of Washington Office of News and Information.:

What if swallowing a pill with a camera could detect the earliest signs of cancer? The tiny camera is designed to take high-quality, color pictures in confined spaces. Such a device could find warning signs of esophageal cancer, the fastest growing cancer in the United States.

A fundamentally new design has created a smaller endoscope that is more comfortable for the patient and cheaper to use than current technology. Its first use on a human, scanning for early signs of esophageal cancer, will be reported in an upcoming issue of IEEE Transactions on Biomedical Engineering.

An endoscope is a flexible camera that travels into the body’s cavities to directly investigate the digestive tract, colon or throat. Most of today’s endoscopes capture the image using a traditional approach where each part of the camera captures a different section of the image. These tools are long, flexible cords about 9 mm wide, about the width of a human fingernail. Because the cord is so wide patients must be sedated during the scan.

The scanning endoscope developed at the UW is fundamentally different. It consists of just a single optical fiber for illumination and six fibers for collecting light, all encased in a pill. Seibel acted as the human volunteer in the first test of the UW device. He reports that it felt like swallowing a regular pill, and the tether, which is 1.4 mm wide, did not bother him.

Once swallowed, an electric current flowing through the UW endoscope causes the fiber to bounce back and forth so that its lone electronic eye sees the whole scene, one pixel at a time. At the same time the fiber spins and its tip projects red, green and blue laser light. The image processing then combines all this information to create a two-dimensional color picture.

In the tested model the fiber swings 5,000 times per second, creating 15 color pictures per second. The resolution is better than 100 microns, or more than 500 lines per inch. Although conventional endoscopes produce images at higher resolution, the tethered-capsule endoscope is designed specifically for low-cost screening.

Using the scanning device is cheap because it’s so small it doesn’t require anesthesia and sedation, which increase the cost of the traditional procedure.
