Paralyzed man takes a walk in SecondLife

 

Using only his brain waves, a man paralyzed for more than 30 years took a walk in SecondLife, Japanese researchers said Monday.  Headgear, electrodes that monitored brain waves, and a mircophone let the man  walk and talk with another character in the virtual reality game. (Yahoo News, 06/02/08)

Scientists closer to understanding brain thought patterns with new computational model

 

Scientists at Carnegie Mellon have developed a new computational model that correctly determines brain activation patterns associated with words. Computers using this model predicted what each subject's brain pattern would look like when thinking about certain words. (Science Daily, 06/02/08)

Microsoft and HP enter into deal to make Live Search default search tool on personal computers

Microsoft announced a deal with Hewlett-Packard on Monday which will put Microsoft's Live Search toolbar on all HP personal computers shipped in the US and Canada starting in January. Additionally, computers will ship with Silverlight preinstalled. Silverlight is Microsoft's answer to Adobe's Flash plug-in and is required to run the Live Search toolbar.  (BetaNews, 06/02/08).

Researchers develop means to more cost-effective quantum key distribution

Researchers at the U.S. National Institute of Standards and Technology (NIST) have demonstrated a simpler and potentially lower-cost method for distributing strings of digits for use in quantum cryptography—the most secure data transmission method, Science Daily reports. Detailed in an upcoming paper, the new "quantum key distribution" (QKD) method reduces the required number of detectors, which are described as "by far the most costly components in quantum cryptography." Researchers note that the minimum-detector arrangement reduces transmission rates by 50 percent. Still, the NIST system "works at broadband speeds, allowing, for example, real-time quantum encryption and decryption of webcam-quality video streams over an experimental quantum network," according to Science Daily (Science Daily, 5/30/08).

Carnegie Mellon researchers create computational model to predict brain activity

Scientists at Carnegie Mellon University have created the first computational model that can predict the unique brain activation patterns associated with names for things that you can see, hear, feel, taste or smell. According to the release, the research team developed the computational model "by using fMRI activation patterns for 60 concrete nouns and by statistically analyzing a set of texts totaling more than a trillion words, called a text corpus." The computer model combines this data concerning how words are used in text to predict the activation patterns for thousands of concrete nouns within the text corpus yielding accuracies significantly greater than chance. Moreover, the model "proved capable of predicting activation patterns even in semantic areas for which it was untrained," according to the release. The findings appear in the May 30 issue of the journal Science (Carnegie Mellon University release, 5/29/08).

New nanoscale assembly technology created

U.S. scientists say they have created a technology that improves the assembly of single-walled carbon nanotube networks from microns to inches, United Press International reports. The researchers at the National Science Foundation's Nanoscale Science and Engineering Center for High-rate Nanomanufacturing at Northeastern University, in collaboration with researchers at the University of Massachusetts and the University of New Hampshire, plan to display the process during next week's Nano Science and Technology Institute's Nanotech 2008 Conference in Boston. According to the scientists, the new technology creates a viable circuit template that can be transferred from one substrate to another for optimum productivity. They add that the revolutionary assembly process can "scale-up" nanoscale structures on the wafer level and may be able to change the way electronics and other applications are developed for consumers (UPI, 5/29/08).

Virtual worlds tapped for distance learning
Online education is increasingly investigating the use of virtual worlds such as Second Life for distance learning opportunities, the AFP reports. The trend involves enabling students to act through animated characters called "avatars," mingling in simulated school settings and embarking on Internet-based quests for knowledge. For example, San Jose State University in California has built a campus at Second Life spanning 16 digital acres with school buildings that Library Sciences Department students use for classes and experiments. One 15-week virtual-world class boasts 30 students who signed-up to learn about the application driving the Second Life program. While such class simulations are considered unconventional, industry analysts suggest the methods are not unique, the AFP notes. According to Sloan Consortium's survey director, who researches education trends, just a small fraction of the more than 3.5 million U.S. residents that took online classes last year did so in virtual worlds. The major barrier, according to the director, is finding constructive ways to leverage the technology (Sherr, AFP/Yahoo! News, 5/30/08)
